Subject:	 New ETX owner
Sent:	Sunday, May 31, 1998 15:18:37
From:	dranselmo@uswest.net (Don)
I have just received my ETX and set it up for the first time
yesterday. The immediate problem I had was that I could not get
the 45 Deg prism or the camera mount to focus to infinity on the
photo port. I moved the foces knob out on the shaft and it fixed
the problem but it made me wonder what kind of inspection process
Meade uses since this is very fundamental. The slow motion RA
control is very sloppy but does work. It is too bad you can't
move from the camera port to the eyepiece and not have to
refocus. Enough complaining, my first look at the moon was
spectacular and the motor drive did just fine for the 30 min I
kept it on the moon. I did ,and still have problems getting a
sharp image on my nikon screen. Aer their any helpful hints on
getting good field photos and shots of the moon.
I would not even attempt any planets until I get some advice. I
also purchased the basic camera adaptor to use the camera on the
90 deg port and can find no info on using it in the manual. Can
you safely use the 26 deg plossel eyepeice in a Nikon ? will it
clear the mirror in the Nikon ? It is a beautiful instrument, I
wish it didn't have so much plastic in it's construction, but at
$595. that might be asking too much. How useful are the setting

Is the scale reversed for the N hemisphere? Does the procedure
described in the manual work and is there a better way to set it

Hope to hear from you, This is my first telescope so I have
nothing to compare with.

Don Anselmo.

Mike here: Most of your questions are addressed here on the ETX web site. Just do a search on various terms. With the camera adapter, the eyepiece does not go inside the camera body; at least it didn't on my Pentax. There has been some discussion that the ETX manual is incorrect in that the RA setting circles are reversed on some ETXes; north is actually the southern hemisphere one and vice versa.

Added later:

Thanks for the rapid response. Yes I should have explored the web
site first. I did find a lot of answers. I was able to make the
26 mm eye peice work on my Nikon by removing the rubber cup.
However the image ,at least for field photos seems much better
without any eyepeice in the adaptor. Any explanation?

Mike here again: Glad you were able to find the info. As to why the image may look better without the eyepiece, with EP you just have a telephoto lens of 1250mm focal length. When you add the eyepiece you add more glass, some magnification, and let less light through. This may be what you are experiencing.

Subject:	Teflon pads

From:	Gandpr@aol.com
You got your ETX in 9/96. I got mine in 6/96. Does yours have the
teflon pads described in the user comments? I took mine apart for
the first time yesteday to do the hanger bolt fix and I can't
find any trace of these beasts. Could this be a design
'improvement' since mine was made, or am I just not looking at
the right things?

Thanks for your dedication in keeping this site up and running. A
great help to us all!

Greg Randall

Mike here: Since I've had no need to go exploring inside my ETX I've not looked for the pads. Maybe those that have noticed the pads will send me the month/year when they got their ETX. Then we'll see if there is a pattern.

Subject:	 My ETX bearing experience
Sent:	Saturday, May 30, 1998 15:18:14
From:	mahlon.r.haunschild@ac.com
First, let me congratulate you on a very fine Web site, full of
useful tidbits of information.  Keep it up!
Now, to business.  As a brand-new ETX owner, I was thinking that
the bearings in the 'scope mount were just supposed to be a
little bit sticky. It's my first-ever REAL telescope, and what do
I know about these things, right?  Then, when one of the three
R.A. bearing pads under the setting circle oozed out of the mount
and dropped into the palm of my hand (the other two weren't far
behind), I suspected that something was afoot. That's when I went
looking for some Net-wisdom on the ETX, found your Web site, and
was surprised to see that I was having the same sort of
difficulties that others were having!  Here's what I came up with
as a "fix" for this set of problems, after a lot of thought and a
few false starts.

First, bearing lubrication:  I have a tube of what is known as
"Pedro's SYNgrease", a high-pressure synthetic grease that is
intended for use on any slow-running bearing that is exposed to
the elements, such as bicycle hubs and bottom brackets (for which
it is sold).  I also use it on such things as my photo enlarger
focuser and condenser control.   It's really difficult to wipe it
off of your hands, and soap 'n' water barely takes it off.   I
used this stuff (in VERY SMALL quantities) on the declination
bearings (I also smeared an EXTREMELY small bit on the portion of
the right-side tube arm that lies inside of the dec. lock), the
R.A. bearing and hubs, and the inside and upper and lower edges
of the R.A. drive gear hub, which ride inside of matching
recesses in the base and fork.   You should be able to find this
grease at better bicycle shops; if not, try REI Co-op at

Second:  the three tiny little R.A. bearing pads:  I happen to
have some .015" thick adhesive-backed Teflon tape, which I used
to replace the three stock pads.  I added three other pieces of
tape diametrically opposed to the three stock pads' locations, in
the theory that "more is better".  I also noticed additional
raised bits of plastic in these locations, and that the fork had
been wearing on these also.  Do NOT overtighten the screw that
holds the R.A. axis together; this warps the base and hub!  This
was one of my early mistakes, mine is now barely more than

The result:  The declination axis is now ABSOLUTELY smooth as
butter, with almost NO stickiness at all!  As a matter of fact,
the 'scope really wants to tilt down now, unless an eyepiece is
in the eyepiece holder (maybe I overdid the grease a bit).  But,
the grease seems to be heavy enough to keep this from happening. 
The R.A. axis is MUCH better than it was, but still not quite
there.  Rotationally speaking, it's almost as smooth as the
declination axis, but the fork still rocks a tiny bit on the base
because the Teflon tape that I had is .015" thick, while the
stock pads are .030". On inspection, I can see that the R.A. hub
& bearing assembly is dimensioned for the thicker pads, because I
can see daylight between the pieces of Teflon tape and the bottom
of the fork.   Nevertheless, I honestly can't believe that it's
the same mount, and I do think that I'm on the right track.

Small Parts, Inc. of Miami Lakes, FL sells Teflon sheet in a
variety of forms, one of which is .030" thick and etched on one
side so that you can glue it to things.  I think I'll get some of
this and make some better (bigger) pads.  One of the problems
with the stock pads is that there isn't enough adhesive surface
for them to stay put, and the other problem is that there needs
to be six or eight of them spaced around the base, rather than
three.  Could someone report on the size and quantity of the
replacement pads that Meade is passing out?

Cowardly disclaimer:  I have NO idea what the long-term effects
of the grease on the plastic are, so You Are On Your Own in this
area.  Since it's a synthetic, I would suspect that it's fairly
benign, but only time will tell.

Will pass on further info once I get the Teflon.  BTW, the 'scope
works really well on my Bogen 3036 tripod / 3047 head
combination, but I'm going to fab an adjustable wedge out of some
oak and other h/w that will screw down directly onto the top of
the tripod's center column, eliminating the need for the tripod
head and its associated height and weight.  Will also report on
this when I get 'round to it.

Later on.  Gotta get back to the skies...

Great web site Mike.  I've made it a frequent stop since I bought
my ETX two months ago; thanks for putting up an invaluable
resource for this great little scope!  I quite like my ETX and
have been fortunate insofar as I have experienced none of the
quality control issues mentioned by other users, though my timing
by buying the scope when no nighttime planets are visible could
have stood some improvement.
First a comment in response to a recent post regarding good
beginner's books.  As a thoroughly untutored greenhorn when I
bought my scope, I picked up a copy of Peterson's Field Guides to
the Stars and Planets upon recommendation of an astronomer friend
of mine.  In addition to naked-eye and telescope sky maps, the
book contains a lot of explanatory material which I have found
instructive and useful.  It's $18 for a 500-page paperback which
fits in a coat pocket.

Now for my question.  I know little about photography and nothing
about tripod heads.  Tripods are simple enough devices, but I am
interested in picking up a Bogen and they offer pan/tilt heads,
fluid heads, 3d heads, and all manner of confusing other styles. 
Which is most appropriate for equatorial mounting of the ETX with
or without a JMI wedge?

Also, what is the preferred method for cleaning the front surface
of the objective lens, or the eyepieces for that matter?  Is it
safe to use a soft brush, say a horsehair brush, for dust, or
will that damage the coatings?  Is "optical cleaning tissue"
really equivalent or better than a cotton handkerchief, and what
kind of cleaning solvent is recommended? I thank you in advance
for your advice.  Keep up the great work with the site.

Mike here: Search the site for "Bogen"; there are lots of comments on their tripods. And searching the site for "cleaning". You'll find some tips.

From:	lrp@bullhead.adp.unc.edu
I've followed your ETX page since I received my ETX as a
Christmas gift from my wife last Christmas.  I am very interested
in getting into astrophotography and will probably eventually
invest in an LX10 or LX50 (an LX200 in my dreams).  That's
probably not going to happen for at least another year though so
I would like to begin exploring the capabilities of the ETX.  I
currently have my ETX mounted on a Bogen 3221 with a 3030 pan
You review the JMI wedge on your page and mention that it can be
mounted on a photo tripod.  Have you tried that or do you know
anyone who has? I've spent a couple of hundred dollars on the
configuration I have now and if I can add a wedge without the
necessity of a new tripod, I would prefer that solution.  I can
achieve a very rough polar alignment with my current setup (I
have managed to track M42 for around an hour) but I would like to
achieve the best alignment I can before attempting any planetary

Do you know of anyone who has any experience using the setting
circles on the ETX (another reason to achieve a good polar
alignment)?  I think mastering the setting circles will greatly
improve my viewing pleasure (I'm not really into spending most of
my limited observing time star hopping)?

Do you have any tips for using an SLR camera for eye-piece
projection photography (actually the afocal method you describe
for your Casio)?  I assume you leave the 50mm lens in the camera
and do your best to hold it still?

I'm considering getting the JMI piggy back adapter and an Orion
EZFinder.  Will I be able to mount both of these accessories
without them interfering with each other?

Any other tips you might have for someone who is interested in
beginning to explore astrophotography with an ETX?

BTW, when you reply, please CC this to my home email address if
it isn't too much trouble (no problem either way).  I'm sending
this from work and I'm accumulating a folder of useful astro tips
at home.

Mike here: The JMI wedge can be mounted on a Bogen tripod. They modified it just for that brand. I've used the setting circles a few times. They work. In particular that is how I located Venus in the daytime. As to using the SLR, I did try that with extremely limited success. I actually get better results from the Casio! Don't know about the Piggyback mount and the EZFinder. Probably will work. You can slide the mount all the way rearward and leave the front most portion of the tube available. Check out the Astrophotography pages on the site for lots of details about ETX astrophotography.

I know nothing of  astronomy,  I just point and get excited when
I  see anything. (Moon and Mars - more of the Moon than anything
else). I have been using a SIMMONS*  and recently was given as a
gift the ETX.  Can you recommend a book, which will get me beyond
just pointing the telescope and wishing for the best.  Yes, you
guess correctly the ETX is still in the box.   Help!

From:	cann@axionet.com
Tell Ray not to worry. My ETX and two others that I have seen,
have the same 'broken stump'. It appears to be just a flashing
left over from the casting. I know it looks a bit rough but they
all appear to have it. I used some vaseline on the bearing
surfaces at the edges and this seems to smooth things out. I was
concerned about using any regular oils and greases in case they
start to soften or heaven forbid, dissolve the ABS plastic.
Good luck Ray.  Cheers....Doug....

From:	gbass@taconic.net
I did receive a package of teflon pads in the mail from Meade,
but with no instructions as to their use. I doubt I'll have a
chance to fiddle this week as I'm about to head south for two
weeks on the coast of NC with family. Last year at this time I
began using the ETX there as a new purchase. This year I am
hoping to take a year's worth of experience (though it was a very
difficult winter weather-wise to do much observing) and get to
know the sky better through the scope. I'll work with the pads
when I get back as I'd rather live with the wobble than take a
chance on messing up the scope when I have these two weeks to
As I mentioned, I purchased the scope about a year ago - right
after Hale-Bopp so I never got to view the comet through the
scope. It must have been quite a sight! Having observed the comet
with some regularity, I began to think that I might, in fact,
profit by something a bit more powerful than 10X binoculars. I
must confess that I have always been a victim of "bigger is
better" and, thus, must congratulate myself on my choice of an
ETX. I just knew (for once in my life, at least) that bigger
might not be better: A big scope would be too difficult to manage
and, if I were going to use an instrument on a regular basis, it
would have to be very easy to transport and set up. I purchased
the ETX mainly on the basis of the Meade reputation, and reading
their catalog - so I was not a very savvy shopper. It was not
easy, then, to get one. Astronomics ( astronomics &
christophers, ltd. Telescope and Binocular Mail Order ) was able
to ship one in a week- but all other dealers were talking six
months. I want to say that Astronomics will send some excellent
literature on telescopes and equipment when one requests their
catalog - very credible information on the different types of
scopes and what each is best at doing.

Along the way, I also have purchased the following Meade lenses:
a Barlow, a 13.8 SWA (these two are often in use together - maybe
my favorite combination with the right seeing - and I also love
the 13.8 by itself), and a 9.7mm. which I don't find myself using
much at all. I also have enjoyed using a Thousand Oaks solar
filter and am even thinking of (some day) investing in a H-alpha
setup so that I can see solar flares. I purchased a stable camera
tripod from a local photo shop which seems fine so far even when
the scope is polar-aligned. (More about tripods in a moment).
Since I am observing in the humid northeast, I invested, after a
soaking or two, in the Kendrick system has kept me dew free on
some very wet nights. I do have a soft Meade bag, which, like
others have mentioned is small and offers little, if any, real
protection. However, it does allow me to carry the scope down the
block where I need to be to enjoy dark skies. When I bought the
scope I figured that it would be impossible to use it for
astrophotography, but I have really been enjoying the pictures
you and others have provided. I want to learn to star-hop better
before I get into the next round of purchases, however.

I'm still perusing the feedback archives - have worked my way
back to December '97 (slow going because of major house
renovations). I can tell from scattered reports that there seems
to be some variability in the tracking rate between scopes. I've
found mine to be quite good as it runs about 2.5 minutes slow in
an hour. So, no complaints there. My one big problem is now
becoming a bit more clear. One part of my mind was blaming my
tripod, and my sighting of Polaris, while another part was
thinking there was something wrong with the scope. I'd align the
same way, centering Polaris in the 26mm lens, and some nights
things would track forever. Other nights, nothing would stay in
view - might as well not have had a clock-drive in the first
place. Now I am beginning to understand that the RA clutch
mechanism might not always be locking and so will be looking to
fix that along with the wobble.

I've mainly been viewing the moon and planets (all through the
fall). I remember being absolutely amazed at my first sightings
of Saturn and Jupiter in the late summer evenings. Enjoyed them
all during the fall, and enjoyed showing them off to friends (big
and little) as well. I'll never forget one morning last summer,
getting up around 3:30 to get a high view of Saturn and Jupiter.
Almost jumped out of my skin they were so sharp. I must have
enjoyed one of those one-in-a-thousand episodes of clear seeing.
Saw five clear bands on Jupiter, and the Cassini division and
bands on Saturn -- easily! I was so elated I got everyone up to
see. They actually didn't mind once they'd had a peek. I just
wish I'd been a more sophisticated observer - could have done
some drawing, at least. Also spent a wonderful, but frightfully
cold, hour on New Year's Eve looking at Venus, Saturn, Jupiter
and Mars. Beautiful sights at sunset. Wows from all observers
each time I moved the scope. I hope to get better at learning my
way around to some deep sky objects this summer. Sure am missing
those planets.

Sorry this is getting so long: one comment and a question or two.

I just purchased DeLorme's Street Atlas USA v.5.0 because the
cursor position is accompanied by latitude and longitude. It's
cheap, and a good mapping program (also works, so it claims, with
GPS and laptop in the car), but I love it for the lat-long
readouts. I now "know" where I am - even when I'm not here! For
those who roam, it's a great way to get those numbers.


Has anyone done any flying with a hard-case (like those reviewed
and already commented on) since the airlines have become strict
with carry-ons? Does the X-L Doskocil still fit?

One problem I'm having concerns finding a comfortable viewing
posture. I'm missing out on long slow looks at objects because my
scope never seems to be at the right height. I'm also working on
getting some little friends (10 and 8) interested in viewing with
me, so we have different viewing requirements. My pod height is
only adjustable by altering leg height and it's a pain to juggle
three legs with the scope on top to find a place where we can all
see. Of course, when the little ones can see, I'm left straining
my lower back. Do any of the tripods mentioned in your equipment
reviews or by others have adjustable center posts? Do I need one
of those adjustable height chairs I've seen advertised (big bucks
- but maybe worth it?). How do you all find comfortable positions
for long viewing sessions?

Thanks again for maintaining this terrific site. Look forward to
chatting again when I get back from NC. And, look forward to even
more catching up!

good seeing,

Subj:	ETX--impressions after a couple of months
Date:	Thursday, May 28, 1998 08:15:25
From:	kfisher@rim.net
Well I'm relatively new to amateur astronomy...a couple months
ago I went to a local telescope dealer and asked what a good
starter scope would be and he pointed me to the ETX.  I must say,
I'm really impressed with the scope after the first two months of
I mainly bought it for planets, but unfortunately my timing
hasn't been all that great as the planets have been largely early
morning and low horizon creatures for the past couple months. 
So, instead, I've been learning the skies and trying to see as
many deep-sky objects as I can. With the ETX some things have
been spectacular (The Hercules cluster and the Orion nebula, for
example) and others disappointing (NGC 2392).  As soon as the
planets start appearing at night again I'll start making
observations of them (since I can't seem to wake up early enough
to see them in the morning). A lot of my observing has been city
viewing, mainly from my balcony (which faces the northwest).

I have purchased a number of accessories that I'd like to
mention...I have the Meade 2x barlow, a 9.7mm and 6.9mm eyepieces
(along with the 26mm that came with the scope).  I have had
really good results with the 9.7mm eyepiece on deep-sky
objects...the Hercules cluster looked really good through this
eyepiece.  The 6.9mm is really pushing the ETX though.  Don't
even bother trying that on deep-sky objects as it just doesn't
bring in enough light.  On the one morning I DID rouse myself I
managed to observe Venus with the 6.9mm eyepiece...you could tell
the phase of Venus easily, however the image was somewhat blurred
(it was a relatively clear, stable morning as well).  The Meade
2x barlow is also a great accessory...it works really well with
the 26mm eyepiece (I almost never use the 26mm eyepiece alone

I recently purchased a Lumicon wideband filter for light
pollution, however I haven't had a chance to really test it (lots
of cloudy skies recently in southern Ontario).  I DID try it on
NGC 2392, but I didn't really see much of an improvement with it.
 I will try it on some brighter deep sky objects soon, weather
permitting.  I am also assembling the 'Dry Eye' dewcap and
optical heating system, I'll send my opinion of that along when
I've got the whole thing together on my ETX.

As far as good 'starter' astronomy books, I can only recommend
Nightwatch by Terence Dickenson (for the rank amateur :) and The
Backyard Astronomer by Dickenson and Dyer.  Excellent books,
especially the Backyard Astronomer which gives a LOT of good tips
for those who want to buy a telescope.

PS--I too have noticed a certain wobbliness to the base of the
ETX...or rather, the plate on which the ETX connects to the worm
drive seems wobbly. I noticed something significant about
this...the plate rotates on little plastic guides that are on the
bottom part of the ETX base (right under the declination scale). 
There are about 4 or 5 of them and they aren't really noticable. 
On my ETX, one of them came out and as a result, the whole scope
began to really wobble on it's base.  I don't know if this will
help anyone, but just make sure that the plastic guides are still
there...on mine one of them came right out and I still need to
find a good way to adhere it back in place.

Sent:	Tuesday, May 26, 1998 19:30:50
From:	davidthi@lava.net (David Takamiya)
As with many other people it seems, I also got my first lessons
in using the ETX from browsing your great website immediately
after purchasing my ETX last November. I did look up Meade's site
first, but they were next to useless when it came to practical,
down-and-dirty  information. Keep it up, and, yes, Meade should
definitely pay you to maintain this site.
Someone asked about the Bogen 3021 tripod (which is ONLY the
tripod without the head, by the way): I'm using it with a dinky
3028 head because it came that way when I purchased it used. I
will soon change the head to either a 3039 (Super Pro), 3047
(Deluxe 3-way Pan Head), or a 3275 (410 Compact Gear Head). Does
any one have practical experience with the compact gear head? As
far as the tripod itself is concerned it is very solid compared
to most other brands of tripods but it is a relatively
lightweight model that is rated for only a little over 13 lbs.;
there are five or six sturdier tripods in the Bogen standard line
but both increased weight and cost come with more solidness. In
essence, a 3021 without too many heavy accessories hanging off
the ETX is perfectly fine. And this particular model has three
click-stopped spread angles for the legs, giving it great
stability, especially useful here in Hawaii when polar aligning
at this low latitude.

Check out Bogen's website and you can print out the specs for
their different tripods and heads. They are at:

From:	Ray.Wartinger@usa.xerox.com (Wartinger, Ray C)
I hadn't checked the feedback for awhile.  My teflon pads are
ancient history -- fell off almost immediately.  Seemed to have
been stuck on with rubber cement.  Silly design!  Anyway, I'll
give Meade a call and get them to send me a replacement set. 
Don't know if I should mention the broken post problem 'cause
then I'd be admitting that I've had it apart.  I guess the
warranty is gone by now anyway.  I've made some minor improvement
just by adjusting the screw tightness (another silly design!) but
the teflon pads may just be the problem after all.  I'm also
experimenting with a larger RA knob.  This has two advantages:
first, it gives me a bit more control and leverage; second, it is
easier to reach.  I'm even thinking of putting a large gear on
the RA shaft and driving that with a smaller gear attached to a
large knob.  This would give me even slower motion and put the
knob further out the back so it would be very easy to reach and
turn.  I'll keep you posted...

Added later:

Big breakthrough!  After reading your suggestion about the teflon
pads, I tried a small plastic shim where the original teflon pad
had once been and the RA action smoothed out completely!  I only
replaced the one in the back since that takes the weight when the
fork is tilted toward the pole.  Man what a difference!  Since
those little buggers fell out so readily I'd discounted their
importance, but as it turns out, they are vital to the smooth
operation of the RA mechanism.  The plastic I used was cut from a
soft margarine container.  The outside is real shiny so I put
that side up. After cleaning both surfaces with a bit of acetone
(don't use too much), I stuck in on with a bit of double sticky
scotch tape, then trimmed it flush with a razor knife.  Works so
well I'm not sure I'll even bother to order the real replacement
pads.  I can't thank you enough.

Subject:	 Mirror flop?
Sent:	Monday, May 25, 1998 08:36:54
From:	prairie3@gte.net (Walt)
I was reading an article from Doc Greiner's ETX Info site:
"Fixing the Flip Mirror in the ETX

I found that the flip mirror, when in its 90 degree position, was
not as stable as I would have liked. Each time the mirror was
flipped, the centering of the guide star in the eyepiece changed
considerably even though the star usually on the guider chip. 
But in some cases the flip mirror was badly enough set that a
star in the center of the eyepiece did not fall on the chip at
all.   This problem needed to be fixed before the ETX could be
used with the tiny 216XT chip.

The reason for this problem is that the up position of the mirror
is established by a spongy pad on the back of the mirror which
does not  firmly establish a stopped position.  The fix allows
for precision adjustment of the angle of the mirror in its up
position. (90 degree position)  The angular accuracy required for
the mirror is quite high.  A good fix can be effected in the
following way."

This sounds like a possible cause to the object shifting that I

Nice web site.
Can the finderscope be affixed on to the right hand side of the
tube rather than the left (as pictured)?



A crash reduces your expensive

Mike here: Not without drilling some holes. But alternative finderscopes like the QuikFinder and Telrad can be mounted wherever you like.

Sent:	Sunday, May 24, 1998 00:45:24
From:	prairie3@gte.net (Walt)
It took 30.5 years, but, finally I have my very own telescope!
Wow, I sound like a kid in a candy store! I guess that's because
I've wanted one since the age of 9.( I will be 40 yrs old this
year!) I just want to tell you that I love everything the ETX is
and isn't. From the shiny deep purple OTA to the compact little
fork mount, even the little 6 X 20 finder! I have used my new toy
at least 4 times each week. ( Not counting looking at it only) I
can't wait to get home at night to align and learn more about the
sky. I have purchased the t-adapter and mount so that I can get
into the photography. I bought "Turn left at Orion", by Guy
Consolmango and Dan M. Davis. A real good book for the beginner!
I have seen the double-double; epsilon lyrae, Jupiter, Venus (
didn't know Venus had "phases"!,  could only see 75%.) I took
pictures of Venus and Jupiter with auto-focus on and in my hands.
Of course this doesn't work. But, it was fun! I love to look at
the moon, especially at dawn.
I am a FPGA designer for a large corporation. I have alot of
pressure at work. This scope has allowed me to divert myself and
find, yet another way to appreciate this beautiful world I live
in! I also love to fish and take nature walks. We also have use
the scope to observe nature on our 5 acre farmette, outside of
Rockford, Illinois. After viewing the "DarkSky" map of light
pollution, we find ourselves in a relatively dark area,
considering Chicago is only 75 miles east of our home.

I would like to ask you a few questions about astronomy and the ETX:

1. I bought the 9.7mm SP 4000 eyepiece to get higher
magnification for planets and the moon. But, I notice a small
aura around the center of the lens. I have tried to focus this
out, figuring it was a diffraction ring. But, it's always there!
No matter what I look at. Today I cleaned the eyepiece with
distilled water and a chemical free camera lens cleaning tissue.
Still there! Then I noticed that when I removed the eyepiece from
the scope the image of the secondary was present on the
flip-mirror and it resembled the concentric of the, above
mentioned, aura! Am I seeing the secondary image? Is this typical
of high power pieces? Meade told me how to clean it and thought
that it my be a "bubble". What is a bubble? What do you think I
should do?

2. I also cleaned my 26mm SP 4000 today. I noticed a small
line/scratch/hair on the outer edge of the lens. It doesn't seem
to affect the view, but it bothers me that the eyepiece had the
blemish. I'm wondering if I have to return both the 9.7 and the
26mm to " Natural Wonders" and pick up two new pieces!

3. I seem to get better tracking when I align to the Magnetic
North Pole. What is the relationship between the way meade has
calibrated the drive vs. the Polar alignment reference? Is
Polaris more accurate than the Mag North?

4. Should I purchase a polar alignment tool?

5. Meade states that a ETX tripod/eq. mount will be available
July 98. I really want to buy the "traveler" from Bogen, but am
wondering if I should wait. I also want to use the tripod when I
go camping into rougher country. The "Traveler" has a 3036 leg
tripod with a 3047 head. It seems like the best all=around
choice. And, for only $199.00! Meade will be offering theirs at
$200 also.

6. When I center the OTA using the flip-mirror down position,
view from the eye-piece and then flip the mirror up and view
though the camera view-finder I find that the object is not
centered view to view. Should the object be centered the same in
both views? I would think so if the flip mirror is centered and
calibrated to the secondary.

Well, I've really asked alot of you and I hope not too much. I
love my ETX and want it to perform it's best! I just finishes
dusting it and will soon tuck it to sleep. :) Hope you can help

By the way, is there a ETX users group somewhere?

Thank you very much!

Sincerely, Walt Boyd

Mike here: Glad you like the ETX. It can do a lot as you've discovered. And even astrophotography can be done as shown on my ETX web site. As to your questions, here are some of my thoughts: 1. I haven't seen any "aura" in my Meade 9.7mm eyepiece. From your description I'm not sure what it is. 2. Over cleaning is not a good idea. Most times, dirt and dust on the eyepieces won't interfere. Of course, if it is bad and does interfer then cleaning is required. With that said, if you cleaned off the blemish then keep the EP. 3. The magnetic pole can vary from the earth's axis by quite a bit. This is because the source of the magnetic pole is not on the axis. In some places the variation is small but in others in may be in excess of 10 degrees. Pilots worry about magnetic variation and so this information appears on flying charts. Polaris is probably more accurate but even it is about 1 degree off the axis. 4. Depends. I'm hoping a review can be posted soon. 5. I have the JMI Wedge/Tripod combination and like it. Meade may be sending me theirs for review. Keep watching the site. 6. I've not seen the shifting image when flipping the mirror. Perhaps the problem is related to the aura you've seen. Maybe the scope is slightly out of collimation? There used to be an ETX group online but it seems to have gone away. The MAPUG mailing list and I guess my site are the closest things to a users group.

From:	kimscott@alaska.net (Kim and Scott Girard)
Once again congratulations on a great site!
I wrote a couple of weeks ago regarding an ETX that I bought from
the Nature Source here in Anchorage.  I originally bought it but
discovered that the R.A. control mechanism was broken when I took
the scope out of the box.  The Nature Source was great about
it...they were going to replace it no problem.

However, after this first experience with an ETX and along with
the other reports regarding ETX quality problems I decided to
just get my money back and try another scope.

Since portability was one of my main concerns as well as quality
optics, I bought a TeleVUE Pronto.  The cost was about twice the
price of the ETX but well worth it.  Since this was to be my
first serious telescope I felt it was important to purchase
something that would not turn me of from the hobby.   I consulted
and purchased the Pronto from Martin Cohen at Company 7.  Good
folks....they only sell the best brands and they check out and
test every scope prior to shipment.  Company 7 will spend all the
time you need explaining anything you need to know about buying a
telescope or accessories.  Check them out on the web........

Take care,


Subject:	 I think my ETX is defective...
Sent:	Friday, May 22, 1998 06:38:03
From:	Ray.Wartinger@usa.xerox.com (Wartinger, Ray C)
I've been trying to smooth out my ETX RA motion ever since I got
the scope. I've had it apart numerous times tweaking the RA axis
screw, trying different lubes on the rubbing parts, waving garlic
over it while reciting incantations....  Nothing has improved the
situation.  Moving the scope in RA is verrrrrry sticky and jerky.
 In all those times I've had it apart, I never noticed what I
think is a defect in the bottom half of the drive base. This is
going to be hard to describe w/o pictures...
The screw comes up through the center hole in the bottom half of
the base, and threads into the hole in the top half of the base. 
I think there's supposed to be a post connected to the bottom
half of the base through which the screw passes on its way to the
top half.  In mine, it looks like that post is broken off at the
base.  In other words, the screw passes through the bottom hole,
then *through thin air*, then into the top hole!  There is a
ragged edge around the hole that indicates that the post was once
there but somehow broke off.  Without this post, the drive halves
don't line up properly and the off-axis forces in the base when
the scope is polar aligned cause extra friction.  In alt-azimuth
mode there is no off-axis force and the RA moves smoothly.

I think this happened at the factory since I've never heard
anything rattling in there or seen any pieces when I opened it up
the first time. There's also the possibility that someone else
owned my scope before I did, broke it, and returned it -- then it
was resold to me as if it was new. Grrrrr!

Anyway, can someone verify that there should be this post I'm
talking about? Also, does anyone have any bright ideas on how to
fix it?  I don't think my warranty is any good anymore.  Are
there parts available?  For example, could I buy just the plastic
bottom half of the base, without the motor, circuit board,  and
base plate?  Does anyone have a spare fork mound they don't need
- - like if you bought the Astro ETX but only use the OT?  I'm
open to suggestions and I appreciate any help I get.

Thanks and sorry for the length of this message....

Hi, I'm a novice. I'd like to get an ETX but am held up by one
point. I'm moving to the central pacific (9 degrees north of
equator). I read that polar alignment is unusable for southern
sky observing when at latitudes near 20 degrees north due to the
mechanical limitations of the ETX. Does this mean I can not "lock
on" to southern stars or does it just mean alignment is more
What is the most useful scope/mount combo for near equatorial
(and extremely dark) viewing?


Mike here: The legs that are supplied with the ETX will not tilt the mount far enough to align to the Earth's axis when near the equator. Some heavy duty tripods can hold the ETX in this unbalanced position without tipping over. So that is what you would need.

I've been visiting your site regularly since I got my ETX in
December, and it's really great to hear from people with the same
obsession as mine.  (Stargazing, at least for me, has been a
lonely business.)  I especially like the "ETX home remedy"
suggestions - I dutifully applied the "final fix" to the RA drive
bolt, put a 35mm film can in the eyepiece hole, and was crushed
when I was scooped on the Dymo tape fix for the "shorty" 26mm
eyepiece.  (I used electricians' tape, which was easy to trim to
make the eyepiece parfocal.)  So I was happy to see the question
about the "right-angle finder vs. nose," which I also had to deal
with.  My solution was to get an eyepiece extension tube from
Lumicon (which cost about $20).  The extension tube adds about
100mm to the focal length (bringing the ETX to about f/15), but
now I can use my right eye on the 9.7mm Super Plossl without
uncomfortable contortions.

T-2 weeks away from the end of my classes and the Big Test, Part
I (one part per year...).
I got the new Meade catalog through my job (stock analyst, now
I'm own their mailing list...doesn't mean I'll get answers any
faster than if I were "only" a customer!).

Anyway: In the ETX section they show a tripod. The description

"Field Tripod: The rigid, full-length Meade ETX Field Tripod
allows for standing or seated observations through the telescope.
Manual controls permit precise polar alignment of the telescope's
fork mount for astronomical applications. For terrestrial
observing, where altazimuth orientation is desirable, the tripod
head tilts to 90 degrees."

From the picture it looks nice, but it looks 90% the same as the
tripod on many of the Meade refractors and smaller Newts. So, if
anybody has owned one of those, they can probably tell us how
steady the tripod is. The only difference is the head, allowing
for the mounting of the ETX.

No prices in this catalog, natch.

The catalog does not show any other new nifty devices for the
ETX. There might be something else coming, though. One analyst
report on the company talked in vague generalities of upcoming
products. One was the tripod, another was a mention that Meade
would be selling some version of their computer guiding/searching
capabilities on the lower end telescopes. So maybe we'll get
Meade-designed GOTO for the ETX? If I see anything more definite,
I'll let you know.

(If anybody is interested, the other thing I noticed in the
catalog is that the LX10 model SCT is no longer listed...only the
LX50 and LX200 SCT's...)

I just had a quick look at your "Mighty ETX" website and it's
great! I've got a brief story to relate about a friend who
recently bought an ETX spotter. He purchased the scope "brand
new" from a local retailer in Toronto, Ontario, Canada. At first,
my friend was impressed with the ETX. However, after he checked
the scope's collimation with a Tectron collimation tool, he was
convinced that the optics were misaligned. Star testing that
evening confirmed his suspicions; the sharpest star images were
mid-way from the centre of field to the edge, at the 4-o'clock
position. At centre of field, the diffraction image was a bit
offset and midway towards the opposite edge of field
(10-o'clock), the star images were mush. He returned the next day
to the shop and described the problem. The sales guy listened
patiently and then produced his own Tectron tool. Sure enough,
his collimation tool saw the same defect. My friend then wandered
over to the other ETX in the shop and asked if it could be tested
too. Unfortunately, that scope tested worse than the first unit!
The end result of this was that my friend exchanged his ETX for a
TeleVue Ranger. I'm wondering how many instances you've heard of
or encountered, of ETX mis-collimation? Is it a fairly common

From:	Ray.Wartinger@usa.xerox.com (Wartinger, Ray C)
I recently tried the Apogee Wide Field Reducer on my ETX.  This
was advertised in the Pocono Mountain Optics ad in the June
Astronomy.  Bottom line: I sent it back.  The problem was #1 it
wouldn't focus unless I removed the focus knob to allow me
another couple of turns before it touched the case.  #2, it
greatly restricts the motion of the OT through the fork since it
attaches to the back of the ETX. The focal reducer lens element
is mounted in a right-angle attachment and requires the Apogee
ETX-to-1.25" adaptor.  I thought this would be a neat arrangement
since I could have two lenses on the scope at the same time and
just switch the ETX mirror to go back and forth.  However, since
the two setups needed wildly different focus settings, it wasn't
all that convenient after all.  It did indeed produce a wider
field (about 29x and 1.8 degrees with the stock 26mm EP - once I
got it to focus, that is) and the images looked ok, but the
drawbacks greatly outweighed the advantages.
This still leaves me looking for a decent wide angle solution for
the ETX. Any hints?

Mike here: I also noted the big focus changes in my Showcase Products report but could focus. As you noted, it can restrict movement through the fork. But that is true of a lot of ETX accessories that mount on the back.

I just installed the Shutan right angle finder conversion on my

eye, so I usually I don't encounter any problems with the finder
being in the way.  But when I switch to my right eye, I also have
trouble getting my eye positioned when I use a short eyepiece
without a barlow.  One way to overcome this problem is to slide
the eyepiece about halfway out of the housing making sure to lock
the set screw securely.  This adds about 1/2 to 3/4 of an inch to
the overall length.  You can also use a 1" eyepiece extension
tube, and it will accomplish the same thing.  You will increase
the magnification by probably 10% to 20% depending how far you
draw the eyepiece out of the housing, otherwise there are no
noticeable optical problems that I have noticed.

Thanks for a great web site--its helped me a lot in using my new
I want to mention that I was really disappointed with Meade's
quality control with the ETX  and some of their eyepieces. The
26mm that came with the unit had obvious coating problems and a
6.7mm also had to be returned for the same problem. The ETX had a
loose wire on it and the motor drive wouldnt work. I fixed that
myself. Seems to me that Meade needs to QC their products a lot
better than they do. Their service/customer relationship group is
great and they really work with you,( especially Mike Leigh)to
try to ensure your satifaction. I wrote a letter to Meade's CEO
telling him about my problems and disappointment with their
products---so far, no response. This is the last Meade scope I
will ever buy----Celestron, here I come.

Thanks for a great site

Great site!!!
I got my ETX a few weeks ago and have generally had the usual
plagues of bad weather or a bright moon, but have been having a
blast.  It's set up on a Bogen 3211 with a pan head (no wedge)
and that seems to work well for polar alignment.  My best
accomplishment to date besides great views of the moon was last
night when I split epsilon Bootis (2.8") with a 9.7 Plossl and
the 2x Barlow.  Way cool!

But, I do have two annoyances and wanted to see if anyone had
suggestions.  I have the right angle finder conversion from
Shutan - works great; overall much more pleasant than the
straight through.  The problem came last night when I put in the
9.7 Plossl and found that my right dominant eye had a hard time
getting to the right place because of the right angle finder
stuck in the bridge of my nose!  I could rotate the finder to
move it out of the way, but then it looks like it would interfere
with the forks.  Anybody else have trouble like this with short
eye pieces?  Any ideas?

The other problem is with the ETX itself.  When the RA lock is
off there seems to be an excessive amount of play or jiggle
between the base and the scope.  I can move scope up and down
about 1/16 to 1/8" on the RA rings.  At high powers it really
shakes when the RA lock is off.  Is this normal or is mine looser
than most?

Thanks for the great site and your time to keep it up.

Barry Rayburn

Mike here: I haven't come across the loose base problem or seen any similar mention. Maybe someone will have a good answer. As to the short eyepieces, noses, and the right angle finders, as long as the ETX clears the fork mount you shouldn't have any problem rotating the finder. An alternative is to mount the eyepiece at the rear port of the ETX. See the Accessories - Showcase page for the Shutan Visual Back accessory that allows this and the Accessories - Miscellaneous page for the Meade Erecting Prism.

I'm finding that there are very few eyepieces to select from in
the .965" range. I have found several .965 to 1.25" adapters that
would allow me to select from the wide range of 1.25" eyepieces.
Can you think of any reasons why this might be a bad idea?

Mike here: The biggest problem might be focus. Depending upon on a lot of factors, some eyepieces might not reach a proper focus with some telescopes. But I've used my .965 Edmund eyepieces (circa early 1960s) with my ETX. See the review on the adapter on the Accessories - Eyepieces page.

Subject:	Zoom Eyepieces on the ETX?
Sent:	Tuesday, May 12, 1998 19:42:42
From:	JaePbond@aol.com
On the use of zoom eyepieces for astronomy, there is generally
the school of thought that serious work (maximum planetary detail
to be drawn, etc), should be done only with single fl eyepieces. 
The counter argument to this is that there is benefit to framing
objects (deep sky, etc.).  So I wouldn't rule out zooms but I
would have to agree that for best performance go single fl.
Specifically, your Nikon zoom is considered to be among the best
along with Swarovski according to Better View Desired.   I doubt
that the Orion listed zooms will be much better.   I would try to
get a custom adapter made to use it if by trying some rough tests
show promise.

Secondly, I use the ETX off the fork mount more than on it.  I
use an Alt-Azimuth mount with slow motion knobs (an old Unitron
unit) on various tripods.   I've found this to be very good for
fine tuning as the fork slow motions are rough compared to this
unit and is very portable with tripod.  Of course you lose
tracking.  I've also used it on a heavier duty equatorial mount
(SP/GP).   The main reason for using these other mounts is if I
decide to use a LAR,  6.3 SCT reducer, and a two inch eyepiece on
a two inch diagonal.  It becomes too bulky to be used on the
fork, both from poor balance and lack of freedom of movement.  
Now it may seem that this type of a set up seems counter to the 
ETX concept but it turns out to be no more bulky than say a wide
field 80mm refractor.   You get better color correction and
obtain a field of view over 2 degrees plus you can switch with
the flip mirror the focal lengths instantly as opposed to having
to unscrew the reducer as used on SCT.

Hope this helps.

From:	nreimer@elele.peacesat.hawaii.edu (Neil Reimer)
Thought I'd send you my thoughts in response to some of the
comments/questions in the user feedback section on your ETX site.
After reading a message from Don Shope on your site and emailing
him, I decided to purchase a Bogen 3036 tripod with a 3039 head. 
Don uses a 3011 tripod which he says is very stable but I liked
the versatility of the 3036.  It can go from 16" to about 7' and
the legs spread at different angles.  The 3036/3039 combination
works great for polar alignment with my ETX at my latitude. 
Polaris is at about 21 degrees above the horizon in Hawaii.  The
ETX on this combination is very stable and not off balanced even
at this low angle.

One drawback would be that the N/S switch on the ETX bottom is
partially covered by the quick release plate on the 3039.  This
is not a problem for us in the northern hemisphere but actually
an advantage because I can't move the switch off the N position
in the dark when I'm moving the wrong switch to engage the motor
drive.  The plate couldn't be used in the southern hemisphere
unless it is modified.

In response to one person's question about using the ETX on a
tripod without the fork mount, I would say that it works fine but
you no longer have use of the motor drive for tracking an object.
 This can get anoying at high magnification.

I read a lot on this site and elsewhere about problems with the
optics in the ETX, which got me a bit concerned.  I have not had
ideal "seeing" so far on the nights I've used my scope so I was
uncertain of its colmination, etc.  This weeked I did a
"christmas ornament" star test.  This is where you place a sphere
in the sun (i.e. christmas ornament, but I used marbles).  You
then focus the scope on the sun's pinpoint reflection from about
75 feet away at high magnification and focus in and out.  The
shapes of the concentric rings gives you information on the
status of your optics. The ETX passed with flying colors.

does it mean?

Mike here: The JMI Wedgepod is a combination of their wedge and tripod. I have comments on the combination on the Showcase Products page. I liked it enough to purchase it after using it for awhile. As to max magnification, your mileage will vary depending on what you are looking at (brightness, size, etc), quality of the optics (all of them), and your expectations.

I reviewed the comments of the ETX by the folks on your web site.
I do see a number of comlaints on Meades ETX relative to quality
control.  As to the 3 ETXs' I returned to Service Merchandise the
one with the missing owners manual was Services fault.  The other
two had never been opened and were just shipped to the store
defective. I can assure you that if the ETX was made in Japan it
would be perfect.  I guess that is why the majority of
electronics sold in the US are made in Japan.  Meade certainly
must like you.  Perhaps you should foward all the complaints to
their Hqs.  They just might make an effort to improve. In time
poor quality control catches up and the ETX just might flop
facing other competition.

Subject:	 Zoom Eyepieces on the ETX?
Sent:	Saturday, May 9, 1998 09:09:59
From:	acl3@sprynet.com (Al)
Over the last several years I have found myself frequently
turning my spotting scope skyward, and thus have become
increasingly interested in astronomy.  Yesterday, I took the
plunge and purchased an ETX.  My first view was of the nearly
full moon, and I can only comment - WOW!  I also learned why the
manufacturers offer polarizing filters; the intensity of the
moon's image with the 26mm standard eyepiece was stunning almost
to the point of being painful.
The question deals with eyepieces.  My favorite spotter is a 60mm
Nikon ED Fieldscope.  The only eyepiece I have ever used is the
Nikon 20x-36x zoom.  This piece was highly rated, and has been
fully functional under a wide variety of conditions and

The current Orion catalog shows manufacturers (Celestron, Vixen,
Tele Vue) offering 1.25" zooms for telescopes.  I understand that
astronomical observation imposes different, seemingly more
complex variables, than terrestrial observation, and at any given
power, the zoom will invariably suffer somewhat when compared to
a single power eyepiece.  However, I would be interested in any
input from ETX users regarding their experience with these or
other zooms as well as general comments on the practicality of
zoom eyepieces for astronomical telescopes.

Secondly, my the ETX on a pretty heavy Bogen tripod with the same
video head used for the spotter.  The setup seemed stable, but I
was wondering about removing the scope from the ETX fork mount 
and setting up like a spotting scope directly attached to the
video head.  I would like to see some comments from users who
have used the scope on a tripod with and without the fork mount.

This is an excellent web site.  I was fully prepared to spend
twice what I paid for the ETX, however the comments of satisfied
users, photographs, and review links convinced me that the ETX
was what I wanted as my starter scope.

I prefer to use my ETX on a table using the 3 tripod legs so that

I plan to place a fixed turntable on the main table which would
turn on teflon similiar to a dob mount.. The ETX with the 3
tripod legs would be firmly set on the turntable by anchoring the
legs via stops or indentations for the leg ends. Then once the
main table is levelled and then the ETX is polar aligned the
turntable would be locked in place. I haven't figured out the
locking mechanism yet.

Eager to learn,


Mike here: I started out with 400 speed film since I had it on-hand. I've since moved to the Kodak Max 800. And yes, you're right. Faster film is better for astrophotography of most objects. Planets and the Moon may not need a fast film, depending upon a lot of factors. Of course, fast film can suffer from an increase in film grain, which may or may not be a factor. I've been pleased so far with the Kodak Max 800 and having it processed onto PhotoCD.

I agree with Mike.  Any scope can produce image blur or shift for
less than obvious reasons.  I, too, have had a "blur" problem
using the time release method with my Nikon FM on the ETX.  I ran
several tests with the camera in place, and, while viewing
through a 12mm X-hair, noticed a very perceptible movement of the
object even with a mirror lock-up.  The hat trick is probably the
best way to go.  But...even some of the blurry shots of a 2-day
old moon look good.

Good luck.  Keep trying!

From:	AstroFrk69@aol.com
it's been a while sinced i have sent an email in but I do keep
coming back to this webpage.  As to viewing the ring nebula with
the etx, i found that when i viewed it, the image of m57 was
crisp and clear.  Without any kind of filter, I was able (and
other people as well) to view the ring nebula, which is a small
planetary nebula of about a 9 magnitude.  Being able to view a 9
magnitude object with a 3.56 inch diameter scope i feel is very
impressive.  With a filter (lumicon's Olll), i am able to see
more details in it.  Another big factor when observing this is,
how long do u look at it for?  The longer an object is observed,
the better the view.  There is a big difference between observing
an object and just looking at it.  I spend up to about 45 minutes
observing one object.  This not only provides better views of the
object, but it trains your eye to become more sensitive.  I have
observed m57 many times with my etx, as well as my 10 inch dob
and 17.5 inch truss.  To be honest, i find the etx to be my
favorite scope.  Every object that I have seen with my other
scopes i have seen with my etx.  M57 isn't a bright object, or
detailed one, but knowing that you're viewing an object about
2,150 lightyears away through a 3.56 inch scope really impresses

Mike here: A couple of other tips on seeing more when viewing faint objects. 1) Let your eyes become fully dark-adapted. 2) Use averted-vision, that is, don't look directly at the object but look slightly off to one the side of it. Try different sides, top, bottom, etc, to see which direction works best for you.

Another solution to the wide-field problem is available from
Orion.  It is possible to purchase a "Large Accessory Ring" from
them which functionally changes the porthole at the back of the
ETX into a completely standard SCT mount.  I got it so I could
use my existing camera T-mount adapter with the ETX.  The ability
to put standard accessories for an SCT on the ETX means that you
can buy any make of wide field adapter (or use one you have) to
obtain the advantages of exposure time reduction, etc.
I'm planning to try one sometime in early summer.  It may be that
the Shutan is better; it may be that the Meade standard or the
unit from other companies is superior.  They are slightly more
expensive, I think.

places.  Its my second telescope.  I tried a 114EQ 4" reflecting
telescope but found it frustrating chasing Jupiter across the sky
(seemed to race out of view every 10 seconds.)
Wouldn't you know, since I got it on Thursday its been raining
and cloudy and they predict rain all weekend!

I've got a question for you.  With no stars to look at I tried it
out on some terrestrial bodies.   I focused it on some white
tulips behind our house (about 300 yards away.)  I was a little
suprised to see some pretty severe ghosting around the white
heads of the flowers.  Is this normal? Will this occur with
planet viewing?  I don't see anything like this indicated with
your moon and planet photos.  Did I get a bad one?

The other thing I noticed it the fine altitude adjustment seems
to have a big freeplay/backlash in it.  When I change directions
it takes quite a bit of winding before it starts moving in the
other direction.

Thanks.  Again, nice informative website (I must have spent 2
hours reading the reviews and tips there.)

Mike here: Are the optics perhaps dirty? Maybe it had been sitting out at Service Merchandise and so collected some dust? Or maybe someone tried to clean the optics and left smeared residue? Either one, especially a lousy cleaning, could result in a bad image. The declination adjustment should kick in immediately if the DEC lock is fully engaged. However, since this is just a friction lock it could be that it has gotten dirty as well as so there is less friction. So, I guess I could begin to wonder how long this scope was sitting out in the showroom (or elsewhere) and under what conditions. I'm not saying that a dirty scope is the culprit in both of these cases but it could be.

Added later:

They just got them in and sold out most of them so I don't think
it sat too long. I did notice the front lens came off rather
easily and there was a piece of material on the inside of the
lens which I dusted off.  Otherwise the lens looked remarkably
shiny and clean.  It was rather scary actually.  Not only did the
front lens unscrew quite easily (as I was trying to loosen the
lens cap) but the body started unscrewing as well.  I had to
tighten the whole tube back down.

How do I clean the lens properly?  I'll want to try that before
returning it.  I read a post on sci.astro.amateur where an
uncoated lens caused these ghosting reflections.  Does that sound

re: DEC lock:  Woops, sounds like a case of "read the manual."  I
didn't have the friction DEC lock fully engaged.

Just gave it another go on some street lights down the block and
didn't see any ghosting whatsoever.  Now I'm wondering if I
forgot to open my glass door and was sighting through it.  I
imagine the thermal panes would play havoc on the image!

If I can get this sorted I think the ETX will be the ideal scope
to introduce my boys to stargazing.  I'll always remember sitting
out a night with my father, gazing, with fascination, at the
moon's craters through his spotting scope.  I was looking for a
telescope that would be as easy to crank out for use with my

Thanks again for the help and great website.

Mike here again: See the March 1998 Feedback archive for some cleaning tips.

Added later:

I checked this morning through the sliding door glass and without
it.  There was not a discernible difference.  Both looked
fine...no ghosting.  Then I remembered the screen door.  When I
viewed through that I got terrible ghosting.  Problem solved.  I
feel a quite silly now.

Subject:	 Help! Using DC camera with telescope

Hope you can help us.  You are unique in your success with the DC
and telescope in astrophotogaphy. We need help, that is our club
members (Everglades Astro. Club.) are anxious to know how you are
able to get a focused image notwithstanding some inherent
obstacles in the DC's.
Please answer the following:

I'm unable to get a focused image either thru the eyepiece or
thru the rear port of my Questar 3.5" telescope.  I am using a
Kodak DC-120 which has a fixed lens and an automatic focus (It
does NOT focus thru the primary lense). It has no manual focus.

Does your casio DC -QV-10 have similar features?  If so, how are
you able to focus, and how do you circumvent (or neutralize) the
camera's fixed lens?

Bottom line, How do you get a fixed focus?

Thank for your help.

Mike here: I guess maybe I've been lucky or maybe just persistent. Taking astrophotos using the Casio is challenging and requires some patience. The Casio QV-10 has a fixed focus lens focused at infinity (except for a macro position which is not applicable for astrophotography). So I can't adjust the focus nor does the camera do any automatic focusing. This is ideal for the eyepiece projection (really afocal) photography. I focus the image in the eyepiece by looking into the eyepiece as normal. Then I place the camera lens up to the eyepiece. Since the Casio has a nice LCD screen I can see what the lens sees. When I have the image I want, I press the shutter button. Then I usually delete that image since I moved the camera during the exposure, which even though very brief, it can be long enough for blurring to occur from handholding the camera. I take lots of pictures but delete them from the camera almost immediately. I eventually get the good photo. If there is a distance sensor IR port on your camera, you might be able to cover it to disable the automatic focusing (although that might fool the camera into thinking the subject is really close!). Since I don't have the Kodak camera, I don't know what else might work. Maybe someone else has some thoughts?
