Subject:	Extension cable for ETX-60AT not working
Sent:	Thursday, January 30, 2003 18:42:06
From:	wahlers@mindspring.com (Wayne Ahlers)
I recently purchased the orion monochrome video eyepiece intending to
operate the ETX remotely.

The controller is marked 35-4700-03. After reviewing various messages on
your site it seemed simple enough. I first tried a 25 ft radio shack
8-wire extension cable. I checked to make sure it was indeed straight
through and verified continuity and no shorts. When I plug it in the
Autostar goes into a self test mode and after you push all the buttons
declares test failure. Plugging it directly into the ETX gives the
normal start up initialzation.

I then tried the other suggestions which was to use a standard ethernet
cat 5 cable and female to female coupler, this results in no display
whatsoever with two different cables, one only 10 ft

All of this with fresh batteries.

The ETX was a very low cost BJ's special, is there something unique with
the controller??  Any advice appreciated.

Thanks, great site.

Subject:	Maximum magnification for ETX-70?
Sent:	Wednesday, January 29, 2003 5:16:26
From:	joseph.a.schlatter@mail.sprint.com (Schlatter, Joe A Jr [LTD])
The rule of thumb that I have seen for maximum magnification is 50 X
aperture in inches.  The 70mm ETX-70 aperture is approximately 2.8
inches. 50 x 2.8 = 140X.  Thus, the rule-of-thumb max magnification with
the ETX-70 would be 140X.

What magnifications have other ETX-70 users obtained before the
magnification starts to blur the object being viewed?

Firstly thanks for your site. It is really well constructed and a
fantastic source of information.

I have just been given my first ever telescope for my birthday, a Meade
ETX 70AT. The only problem I've come across is that the controller
language is set to German. I can not find anywhere in the Menus to
change the language setting so am I right in thinking that the language
is a function of the software and can only be changed by overwriting the
preloaded software?

If this is correct; I guess i need my laptop and one of the cables to
reload the software. Soooooo...... would a #505 or a #506 cable be more
suited AND is there any chance you could send me a URL link for the
current, correct English software please.

Many thanks from a Newbie Astronomer(UK),

And:

No Good Mike,

Still comes up in German. Initial screen is:

(C)00 Meade (10G)

I think I will need that cable and the correct software link. Thanks for
your help anyway, any chance you could send me a link for the Software
Download?

Thanks Again,

Vamp

From:	joseph.a.schlatter@mail.sprint.com (Schlatter, Joe A Jr [LTD])
I was reading the updates on the ETX-70AT site and have a comment and a
question.

COMMENT.

One gentleman reported that his scope was slewing 160 to 180 degrees out
-- not to insult anyone's intelligence -- but -- VERY CAREFULLY enter
the date and time and double-check each entry before hitting ENTER --
A.M. is not the same as P.M. and stars are in different locations from
day to day.

How do I know?  Because I kept swearing at my ETX-70 until I realized
the date was January 22 and I had left it at January 13.

QUESTIONS.

1.  Can I swap the 494 controller from the ETX-70AT with the 497 (I
think that's the model number) that comes with the other ETX scopes and
that has the numeric keypad?
2.  I ordered the software and 506 cable from Meade.  When I installed
the software, it comes bundled with Starry Night.  I already have Starry
Night installed so I skipped that part.  Now, the Astronomer's Control
Panel will not set the scope time to the computer time -- when I try to
do that, I get an error message.  Do I need to have Starry Night running
when I am using the ACP?

Thanks.

Would you consider the etx 70at a good beginner scope to use with a
Nikon 5700? I have never even looked through a telescope, but I am
addicted after look at photos of the moon!

I thimk my concern is will the scope be "bright' enough.

I don't expect miracles at the price, but I would like to be able to
take moon shots in particular.

Thanks for any input.

Thanks so much for taking time to reply! I am so excited about this new
"discovery" (astrophotography) that I can't wait for dark!!

Subject:	ETX-70AT Slewing -- Problem?!?!
Sent:	Saturday, January 25, 2003 19:34:28
From:	kcooke@nc.rr.com (Kevin D. Cooke)
For my recent b-day, my wife suprised me with an ETX-70AT...  I've never
owned a telescope before, so I know I'm in way over my head  :-)

Being a computer geek and mechanical tinkerer by nature, I've been
devouring all that I can as I wait for it to warm up and spend many
hours outdoors surfin' the skies!  Your site has been a tramendous help
(though I still can't seem to determine what the actual differences are
between the Autostar 949 and 947 -- but that another question entirely).

The thing that is troubling me most is some drive noise after slewing. 
All seems to be operating well -- but to be honest, I don't know exactly
what proper behavior of the EXT-70AT is...

The symptom is this: 30 seconds or so after slewing, the drive(s) are
making a subtle whining noise.  The unit is not moving anywhere, but the
drives seem to be trying to say something to me :-)   The whining is not
the same as when I'm slewing; it's slow, it's fast, it's very random.

Is this normal?  Is there something I can do to quite this?  Is the unit
faulty?  Your feedback and knowledge would be immensly helpful. TIA.

-Kevin Cooke

And:

THANKS...  Of course, that makes sense!  I feel a bit foolish now  :-)

One follow up question on the 949 versus 947.  Aside from the keypad and
more memory, it seems there is also a difference with the connectivity.
With the 947, computer connectivity is accomplished via a true RS-232
cable (505) that piggybacks off of the Autostar handheld.  For the 949,
there is no RS-232 connector and so computer connectivity is
accomplished directly to the scope through the use of a proprietary
cable (506).

In both cases (with a 949/506 or a 947/505) I can use a PC to locate and
slew the scope to celestial objects.  Is this true?

Thanks again for a wonderful site and your personal help!

Subject:	Re: ETX 90 v ETX 70
Sent:	Friday, January 24, 2003 10:15:24
From:	andystentiford@blueyonder.co.uk (Andy Stentiford)
I see what you're saying...

I have worked with different scope types over the years and have a basic
knowledge of the optics systems of SCT's, MC's, Refractors, Newtonians
etc. I have always had a basic understanding that the primary mirror is
just doing the same job as the lens in a refractor. I assumed that we
moved to reflectors at larger sizes simply due to the inherent problems
in producing (and supporting) large lenses or systems of lenses. 
Therefore, even though a 90mm MC has a different optical system, it
still theoretically has a smaller aperature - and hence light collecting
area -  than a 70mm refractor.  However, I do see that the MC Reflector
theoretically has more surfaces available for UHTC coatings, giving a
possible increase in "seeability"

Also, the faster (f5) ETX70 scope should be better all round, right?

Apologies if I am being naive or appear to be splitting hairs - I just
would like to have an idea why the 90 is so expensive relative to the 70
if the 70 is, to all intents and purposes, just as good.  If the 70 is
not as good, please could you let me know in which areas the 90 wins the
"head to head" race so I can make an educated purchase.  I have searched
your site (and the net) for a comparison, but have come up with
nothing...

Thanks for your patience! :o)

Please note that the #494 controller that comes with the ETX70AT does

Sent:	Friday, January 24, 2003 6:28:12
From:	dhamilton@Exchange.FULLERTON.EDU (Hamilton, David)
Thanks for the fast reply. I have considered doing both a motor
calibration and a training of the drive. One other thing I did yesterday
was to check supply voltage which was 118 volts then check adapter
output. I was surprised to find that output @ 16.35 volts D.C. This does
concern me. Please be advised that I am a commercial and industrial
refrigeration and air conditioning mechanic, approximately 80% of my
work involves electrical/electronics. The 6 AA batteries have supply of
9 volts D.C. and the adapter is rated at 12 volts D.C. This higher
voltage would certainly explain the much faster/livelier slew rate but
could also damage the motor and other circuitry. Meade was suppose to
have sent a replacement adapter to me on Monday via U.P.S. which I still
haven't received as of Thursday evening. It should have since I only
live about 30 miles from their Irvine facility. This is the first
telescope I've ever had and really enjoy it. I am sorry to say that I am
having very bad luck with Meade products. The first scope would not let
me past the 3rd stage of initialization being daylight savings 'yes/no'
I returned that scope for an exchange. That scope kept going into 'Motor
fault' the scope I presently have doesn't have the set screw in the
focus knob and I haven't been able to get the knob off so as to install
a flex-focus and now I have this adapter problem. I have looked over
other scopes on the computer and at stores and have found the Meade line
to be the best looking and very impressive overall but they certainly
seem to have quality control problems. I am looking to upgrade before
long to something in the 125m.m. size. At this point I am not sure I can
consider a Meade offering. Please keep in touch as your time allows,
also if you have any contacts at Meade, please feel free to forward this
e-mail to them as I still have hope ( though fading) of being a happy
Meade customer. Thank you for your attention in this matter.

Subject:	70 vs. 90

From:	sdbodin@hotmail.com (Steve Bodin)
Just a quick correction to the post on light gathering power of ETX 70
vs ETX 90.

The correct formula:  pi* (diameter/2)^2

ETX70 equals 38 sq. cm.
ETX90 equals 58 sq. cm. deducting the pawltry 5 sq. cm. for the secondary mirror block

And that is a 150% increase in light gathering power. And since the
price of a telescope is proportional to the square of the aperature, I
think the Meade line is an excellent value all the way across.

Clear skies,

Subject:	Powering the ETX-70AT - Another Solution
Sent:	Thursday, January 23, 2003 18:28:01
From:	jackono2@attbi.com (john o'connor)
Powering the ETX-70AT has always been a big problem for me.  I went
through dozens and dozens of AA batteries but they are very frustrating.
 Meade claims about twenty hours life per six pack, but I was lucky to
get five or six hours before the telescope started getting sloppy about
going to and moving around with the arrow keys. So I bought an AC
adapter with a twenty five foot cord which solved the problem when I had
an AC source nearby.  But too often I was out in the field and had to go
back to using the AA battery pack.  Finally I went down to Walmart and
bought a twelve volt lead acid lawn mower battery from them, and a
variable voltage reducer from Radio Shack.  Total cost was fifteen bucks
for the battery and about sixteen for the reducer.  I replaced the plug
on the reducer with a 9 volt connector which snaps right into the one on
the telescope.  This solved all my problems.  I get a true 9 volts going
into the telescope, (I found that the AA battery pack very quickly drops
down to about 7.5 volts or so), and I have never run out of power.  I
have used the rig for three consecutive ten hour nights with no
degradation in performance, and I am sure I could have gotten a lot more
than that.  I have an old automobile 12 volt charger in my garage that I
use to recharge it.  Recharging usually takes less than an hour.  I
carry the whole shebang around in a 5 gallon plastic pail and still have
room in the pail for accessories, maps etc.  The pail fits between the
legs of the tripod, and with the lid in place, I have a small but handy
work space. (I notched the top lip of the pail for the wire).

One caution, however, be sure to MAINTAIN THE PROPER POLARITY when
putting this rig together.  I think that if this isn't done it will fry
the innards of the 70AT the first time it is turned on.

Great web site, glad I found it. 

My wife and daughter gave me the ETX 70 for Christmas. Hopefully you 
might be able to assist with a problem I am having when using the a/c
adapter. When going through the easy two star alignment, the telescope
slews 160 to 180 degrees opposite of where the stars are actually
located. Even after correcting to proper alignment useing the hand box
controls, the scope will slew opposite of the selected planet/star. This
condition does not exist when using the battery pack. I spoke with Meade
customer service, they have no idea what is/would cause this condition.
They are currently sending me a new adapter which I doubt will correct
this problem as the scope motors operate properly useing the adapter.

Thank you for your attention in this matter.

From:	andystentiford@blueyonder.co.uk
Just to let you know that the Christmas ETX 70 is behaving incredibly
well! (unlike the Scottish weather :o).  A recent outing to the Royal
Observatory for an open night really put it through it's paces, and it
delivered clearer, sharper images thru the newly purchased 5mm Plossl
than their larger (8" and 10") portable 'scopes - these Meade babies are
optical gems! (OK, so their SCT's had REALLY seen better days, but even
so...)

Question: I have the opportunity of purchasing an unused ETX90 RA for
the same price as an ETX 70, and was wondering whether this is a
worthwhile purchase.  I ask because the ETX90 (Autostar Driven EC model)
is usually listed at almost DOUBLE the price of the ETX 70.

However, by my simple calculation, the 90 has a smaller light collecting
area than the 70:

ETX 70: pi*7.0 = 22.0 sqcm
ETX 90: pi*9.0 - pi*2.7 = 19.6 sqcm

So why are the 90's so pricey?

I know the 90 RA's are not autostar compatible and have a higher f-ratio
that the 70's making them less good at astrophotography, but there must
be something MAJOR in their favour to compensate for the price
difference, right?

Am I being naive? :o)

Many thanks for all your ETX support!

I recently purchased a new ETX 70AT, I don't think the az motor is
working properly, it seems to jump and lags when I use the hand
controller, subsequently when I tried to 'train' the motor I had little
control over the horizontal. It does seem to track and skew using the
goto. But I have not had a clear night to try it on any real objects
yet.

Could it be a loose drive clamp, the horizontal clamp on the base does
need to go all the way to the end stop to operate in this jumpy fashion.
NB the vertical movement is very smooth.

I got an ATX-70 for Christmas and have a few questions:

1)  After setting up for a 2-star alignment and selecting "enter" on my
Autostar the scope moves fairly quickly to the first star where it tells
me to center it and select "enter" again. When I use my arrow buttons to
center the star it moves very slowly. Slow enough that it is dificult to
"catch" the star as it moves. On two ocassions (once inside and once
outside) when using the arrow keys the scope moved very quickly, but on
all other ocassions it moved too slow to easily center the stars. I
always use my 25mm eyepiece to "setup" and "locate" my objects. When
using my arrow keys should it move quickly or slowly? I can't figure out
how to make it go fast or slow. I don't know what I did on those 2
ocassions to make it move quickly. I read a lot on your website about
the rh knob and how tight it should be. I have tried from very loose to
very tight and the scope never moved faster or slower than before.
Sometime it doesn't even move at all.

2) When turning on the Autostar I come across the "Daylight savings
time" question. The only thing I can find in the manual is that I can
enable it or disable it. I would think that the computer knows when it
is daylight savings time or not by the date entered. Is this more for
areas in the world where daylight savings time is not used? In the US
should it always be enabled?

3) If I am fortunate enough to get everything aligned what should I be
able to see? I have seen the rings of Saturn and Jupiter and it's moons.
  All I see at best focus (with a 6mm eyepiece) is a bright blob for a
planet (and it's moons) and one big ring around Saturn. When I use my
4mm or 6mm with 2x I can never find my object even if centered right
before switching (I suspect here that the Autstar was not tracking
properly and my not have been aligned properly).
Should I be able to see distinct detail in the rings of Saturn?
Should I see cloud layer detail on Jupiter.
Should I be able to see deep space objects (nebulas,...)
How much will light pollution affect the detail?

Thanks,

We got a ETX-70 for Christmas (11E firmware) and the first few
alignments were dead on, but as we've used it more and more the
centering on the alignment (easy align) stars has begun to drift. Last
couple of times we've tried to align it the alignment stars have been
off by huge amounts. For example we tried last night and the first
alignment star was off by 120 degrees in azimuth and 40 degrees in
elevation (star was NE and scope was pointing S when it said it was
looking at the star). Home position is good, I've got a very good
compass and have tried mag and true (-13) and the scope still wanders
WAY off the area trying to find alignment stars. Any idea what would
cause this?

What is the latest version of software for the ETX-70 with the 494

certain which of these is for the 494.  I assume if software says its
for the 497, I can't load it into the 494.

Will I find on the Meade web site both software and firmware upgrades
AND data updates?  How often do they put up data updates?

I have downloaded and installed the tutorial from your web site but I'm
not certain what to get from the Meade web site.

ANOTHER QUESTION:  I have been using my ETX-70 heavily since purchasing
it three days ago.  Weather is cold -- 15 degrees in the backyard. 
Tonight, I told it to GOTO a star -- it got halfway there and I got a

Hi Mike, yet another question I'm afraid.

I finally got all of the accessories for my ETX-70 and instead of the
standard tripod, they've sent me the deluxe one!

I did feel a bit guilty, but all of the messing around that I had to put
up with salved my conscience a bit :-).

As you know, this one has the option of Alt/Az or an equatorial mount.

I understand the difference between the two, and it seems to me that
using the equatorial mount would mean that only one motor would have to
be tracking to allow for the earth's motion.

However, although the 70 has an option for equatorial mounting, the
tripod notes say to use Alt/Az.

What would you recommend?

Hello!..  My name is Joaquin Martinez and I live in Puerto Rico. 
Recently, for Christmas, for a long time I wanted a telescope ans
because nobody gave me one for Christmas, I bought one for myself. It
was the ETX 70 from Meade and I must tell you, it was one of those
fabulous gifts that you said, hey! this was money well spent.  I bought
it from Discovery Store here in San Juan, it was in sale 299.00 plus
tripod and hard carry case.   Very good deal.  I am not an expert in
astronomy,just a rookie, but since the first moment I put the telescope
together, I was able to see the most beautiful stars and planets in
Puerto Rico that you can't imagine.  I saw Saturn with its rings and
Jupiter with its four moons and the moon with all these craters and
maria, that I was not even worried about the mosquitoes around me,
hahahahaha.  I must tell you , it was fascinating looking at the stars
with my new telescope.  I even went to a place in Old San Juan, its a
castle called El Morro Castle, it's a 14th century Spanish fort for
protection of the city against invaders, and I was there, in the middle
of the night, with my telescope fascinating looking at the stars, that
easily past two hours without notice.  I was so happy and 'hooked' with
my new telescope that I began 'surfing' in the net until I found your
web site.  It is OUTSTANDING AND WONDERFUL to see a page with so many
information about the ETX that even you published a book about it.  Good
for you......

Mr. Weasner I REALLY want to buy your book, but this is now tricky part.
Can you tell me please how to get your book and please I am requesting
if you can dedicate the book to me please?  It is possible to buy the
book direct from you and you can sign it please?..It will be very happy
to me reading a book written by a ' master' in ETX and also a fighter

After some testing with the hand controller that came with it, i
determined that it was the controll panel on the scope that was the
problem. I returned it to the dealer tonight and got another one. I
reset autostar and did a new calibration so it will work with this
scope. Tomorrow I will train the drives if its not too cold and see how
it works out. So far it seems to be working, I just have to hope that
this one doesnt have significant image shift in the FOV during focusing.
The only problem that I had tonight with the new scope is that out of
the box it was in polar mode and I cant get the hand contoller out of
it. However this really isn't much of an issue since I will be using
autostar anyway.
Thanks alot.

I got the ETX 70AT for xmas and decided to upgrade the controller from
the included 494 to a 595 controller. I did this because I already had a
505 cable made to connect to the laptop. But, I cannot get the "easy
align" to work."align" works fine with hte included controller.  Is the
595 controller not compatible with the 70AT or am I missing something.
The 70AT isn't listed when I do the "setup" "telescope model" in the 595

Thanks for the info. I was a little worried that something may be amiss
and without any previous experience with these telescopes it was
difficult to make a judgement. Did some rudimentary viewing last night
and I was really impressed with the craters on the moon but the
brightness was a little hard to take (no filter) as was the freezing

slews. It was VERY noisey while it slewed, so much so that my wife
couldn't hear the TV. Is this normal? I realize that sound volume is a

THought I'd post some positive feedback.

I receved my replacement ETX 70 yesterday, I had to work late, skies
were clear(ish) for my 2hour jouney home and the clouded over as I was
unpacking :-(, so have not had time to look at the any stars yet.

However initial feelings are good.

This one is actually a 70, not a 60 :-)

I really had to crank the Alt knob up on the old one, whereas this one
just needs to be 'nipped' up to work. Also, now the bit in the manual
about supporting the OTA when doing this makes sense, this one will drop
under it's own weight, the other was too stiff to do that.

I have since found out that the one I had initially had been put in the
window, and had stayed there for a year, so that may explain it.

The RA scale also rotates as it should.

I guess all of this would have been obvious had I not been such a
novice.

I finally got under the stars with my ETX-70. I was pushed for time, but
manually aligned on the Moon, just to get a feel for what I could
expect. I currently have the 25mm, 9mm and 3x Barlow so obviously I
tried all combinations and was VERY pleased with the results.

Conditions were ideal cold and clear, but with the light pollution to be
expected living near a main road. The Moon was half, so the shadows
really emphasised the craters.

I did point at a couple of very faint stars, but these were just specs
of light, I've yet to try a planet.

After you enter the Time and Date, when the telescope is offering:
Align/Easy

Tap the [mode] key... you're now seeing   Setup/Align

Tap the scroll down (and, for education, scroll up) key
(that's the one on the lower right of the keypad) 
many times... it will cycle past

At each of -those-, tap [enter] to drop into the sub-menus

At the SITE menu, you are offered Select/Add/Delete/Edit

The Autostar can carry 5 sites as quick-access (for example
your home and your favorite dark-sky site), the Select key
picks from that short list.
The ADD choice accesses the 400-odd city database.
The Delete choice removes entries from the "short list"
The EDIT choice lets you adjust a city's entry.. you can 
 edit the Name/Latitude/Longitude/TimeZone
Those Edits only affect "short list" entries.

Given that as an example, try exploring the -rest- of the
Autostar's menu trees... the manual should have a figure
showing most of the stops along the way, but it doesn't 
explore all of the byways and side-pools.

The 140 will (most likely, i haven't actually -tried- it) NOT WORK
with the ETX70... like the ETX90, the ETX70 requires a "shorty" Barlow.
(such as the 124 or 126).  The focus cannot be extended to "reach"
the 140's requirements.

I use my 126 in an ETX70, 90 and LX200gps.

And:

Which is why i put in my disclaimer armwave parenthetical statements.
I remember other postings by folks who couldn't get a regular ETX70
to focus at distance with the supplied eyepieces.

One way to check is to pull out the regular eyepiece and hold it away
from the holder... and see if you can focus.  That gives you the limit
of extension.

Thanks to both.  The 124 should arrive sometime next week and I'm

Thanks, Mike.

I found a good deal on a #124 plus two Plossls (4mm and 6mm) for $39.95
total and placed and order for them.  I realize the Plossls may be
overkill, but when/if I upgrade the scope in the future, they may come
in handy.

I received the ETX-70 from my sisters for Christmas.  They didn't know I
was looking for a scope for my boys (and myself) as well.  After a lot
of research on your site and a few others, I was ready to buy a more
capable scope--maybe and ETX-90 or a Celestron.  I won't, however, look
a gift horse in the mouth and will hold on to the 70 for a while.  I'm
below the novice level right now but have a strong desire to continue
the hobby.

My first assignment was flying A-10s at Myrtle in 1986 and enjoyed it
immensely.  From there I went to Holloman (AT-38s) to instruct before I
got my F-15E in 1991.

Glad to have some things in common with you and I really appreciate your

Hello,I just wanted to pass along some info. that maybe help some fellow

I got my ETX-70AT for X-mas and have enjoyed it every clear night since
I got it. I really liked the supplied eyepieces, but from reading
articles, reviews, and feedback I got the itch to buy some more
eyepieces.

So I went to the discoverystore.com web site and they have a GREAT combo
deal. The set has a #124 2x Barlow, 6mm and 4mm Plossl eyepieces, all of
this for only $39.95. I ordered them and got them yesterday, they have
been a nice addition, plus they were CHEAP!!!

Well I just wanted spread the word for anyone looking for eyepieces and
even a barlow lens for the ETX-70AT and I figured this was a decent deal
that scope owners should check out.

By the way, your site has helped me a great deal learning new things

I am a new ETX-70 owner with no previous astronomy experience.  Tonight,
after several nights of looking at Saturn (manually spotting), I was
finally able to discern a ring around the planet using the
Meade-supplied 9mm eyepiece.  I've read of others being able to break
out the Cassini Division with their -70s and would really like to be
able to do the same.  In browsing the Meade catalog I noticed two
different types of Barlow lenses, the #124 2x Barlow and the #140 2x
Apochromatic Barlow lens.  Which would be a better lens with the
standard Meade eyepieces (26 and 9mm)?

By the way, I've browsed your site for at least two weeks now and was

Like everyone else, I love your site.  Thank you so much for the
information.  I am, of course, a newbie. Just bought the ETX-70 for
Christmas.  After about two weeks of cloudy skies in Portland, Oregon,
we finally caught a break this week.

My family was astonsihed and excited when the first thing we saw was
Saturn and the rings!

My question is about what it looked like.  It was a VERY small point of
white light, with clear, yet almost not discernable rings (you kind of
had to concentrate to see them -- but it was still exciting none the
less).  I used the 9mm, then combined with 2x Barlow, then used the 6mm.
It seemed to be the same no matter which eyepeice I used.  Is this the
way it's supposed to look?  There was no coloration, and it was awfully
small.  Do some people really see the ring division's with this scope? 
Do some see the planet's colors (I see them on photos)?  If so, what can
I do, if anything?  Do I need a bigger scoope?  Is it the conditions (it
was very clear)?

BTW, same with what I think was Jupiter.

Thanks for any help.

And:

Thank you so much for the quick reply.

I guess I got carried away by the great pictures on your site (even
those made with smaller scopes).  I'm adjusting my expectations and look
forward to learning more about the basics first, then moving up to a
larger scope.

Subject:	Is alignment on object of choice possible? Acceptable?
Sent:	Monday, January 6, 2003 13:27:40
From:	kepler@creationimage.com (Kepler Nigh)
I am a new ETX-70AT owner. My dad used to build telescopes and grind the
objectives, and when I was a much younger I enjoyed them so very much.
All that is left of his work is a 3-inch refractor with an incredible
wooden tripod that needs some work on its polar mount, particularly
finding a counter weight for it. His old Erffel (Spelling?) 16.8 mm
eyepiece works wonderfully on the ETX-70AT (to my very untrained eye). I
love tech, and work as a PCRepair and Database instructor. I also worked
at one point as photographer. So the ETX-70AT is the intersection of a
verity of interests for me.

This web site is fabulous, and I just want you to know that it really
makes all the difference -- I'm not sure if I'd been half as far into
understanding and using my telescope as I am now, thanks to you and this
site.

Concretely, my (first) question: Is it acceptable to set up the scope in
Home position, skip through the alignment by allowing the scope to slew
to its chosen objects, and then pick an object from the Object menu, and
slew to where the scope thinks it is. Correct the slew manually using
the motor control arrow keys, and then hold down Enter and SYNC on that
that object. Choose another object form the Object menu, in another part
of the sky and commit the scope to slew to it, and then repeat the SYNC
process on it. Will this provide an acceptable two star alignment? Would
using a planet be too much math for the Autostar?

I suppose I would try it myself, and may yet, but I haven't had many
clear nights yet.

Another question. When I attempt to do drive training, ascension seems
to work fine, as long as I lock it down, but this takes more pressure
than it seems it should. I don't want to void my warranty, so I might
have to send the scope back to Meade, but it seems to work, except...
After I do ascension, I attempt to do declination, and the scope first
slews to the side, and I return it to the correct center point, and then
it slews to the other side, and when I return it to the correct center
point, the ascension is no longer exactly right (as if the scope has
slipped down a bit). If I am training on a specific distant object, this
is annoying, since the object may no longer be in the field of view!
(I'm using the 2X Barlow with the 4mm for training.) It would seem that
the scope is slipping in the altitude, but when I set a terrestrial
marker and slew off and then command a return, the altitude seems fine,
but the azimuth seems to be off a bit. It also seems that the error is
virtually identical always, and that no matter how many times I train,
or align, that I'm getting about the same degree of error throughout the
sky. However slews are probably always within the range of the 25mm
eyepiece but not always within the view of the 9mm. Should I be
concerned, or is this level of error typical for the ATX70-AT?

Also, how cold is too cold for the ETX?

Sorry to have so many questions, but when observing Saturn with the 4mm
lens and 2x Barlow, tracking doesn't seem to be too precise. I must make
constant adjustments. But using the 9mm alone, Saturn seems to be
tracked okay, at least for about 20 minutes. Should I be trying to
adjust the tracking value?

Thanks in advance for your advice and answers to my newbi questions. I
am really wonderstruck with what I have seen already with the ETX, and
maybe someday I'll grow up and be able to have a "real" telescope, but
for now my mighty little ETX is teaching me much, and revealing many
marvels. My family loves it too.

Oh yes... I bought and read your book on the ETX and loved it!

I got my 70At right before Christmas and just got the #827 right angle

I can't attach it. Curious because why would meade even have different
sized hex wrenches. Anyway the hex wrench I got was too small. I want to
stop by the hardware store and get a new one, but I haven't been able to
find the size in the manual or on your site.

Thanks,

By the way thanks for your site and your quick answers to all of my
newbie questions.

And:

The scope mount "sits" over the two holes to the left of the 90 degree
eyepiece holder (each hole contains a hex screw, though the bottom one
on the left is recessed like the both on the right side of the eyepiece
holder, while the upper one on the left is not recessed). There is a
"peg" on the mount that fits the lower hole and there is a hole in the
mount that covers the upper hex screw hole. My guess is that the upper
screw must be removed and then used to secure the finder mount through
that same hole with that same screw. But the hex wrench I got with the
scope is too small for any of those screws.

And:

I got the finder scope used, so it did not contain any instructions. As
for the hex wrench, it is the one I received with the telescope. It
doesn't fit any of the hex screws on the scope, including the one on the
focusing knob, which I plan to replace with the flexi-focus as soon as
it arrives. I can't believe the scope was shipped with that hex wrench.
I've had some issues with National Geographic and that is just another
one. Any idea what the proper size is so I can pick one up?

I hope you can shed some light on this.

I have just got a reasonable deal on an ETX-70 (or so I thought)

I got the scope, tripod, 25mm, 9mm, 4,5 and 6mm and a 3x converter,
autostar 494 for 280.

However then the problems started, firstly non-stop cloud for the past
few days:-).

But the deal was good as the telescope was a display model, what Ive
noticed is that:-

1)       The Declination scale will not rotate as it should, if I
tighten the LH knob up tight enough, then the telescope will not
elevate.

2)       The RH nut has to be done up *much* more than snug to get the
elevation to work at all, regardless if the setting of the LH knob.

3)       Although the base says ETX 70 the telescope front element says
ETX 60

Mainly because of item 3, the shop has no problem changing it, though I
may have to argue about keeping the extra eyepieces :-)

However, my main question is:

Given that 1 and 2 are probably caused by the same problem  over
lubrication, and that I dont want to do damage by over-tightening the
new telescope when it comes, I think that I should go through the tuning
tips, but how do you strip down a 60/70?

It appears to be different to the 90 in that there are no separate
mounting plates for the OTA(?), the mounting plate and the rear of the
scope (where the eyepieces go) seem to be the same molding.

Many thanks in advance

And:

Thanks for the very prompt reply.

You can probably tell from my phraseology (left hand knob etc.), that
I'm a novice at this, the ETX was almost an impulse buy, although I
think that luckily I have an appropriate model for my needs.

You're probably right about opening up a brand new telescope, I guess
that when I get the new one, assuming that it's all ok, it's a judgement
call as to when I'm cranking the RH knob too tightly, ot the autostar
misses targets.

Although I was surprised to see the problems mentioned on your site so
evident in a new telescope, tho' I guess if it's been sat in the shop
window for a while (and is a 60), then it may be fairly old and the
grease may have 'leeched'.

Skies may be better this weekend, so the practice on terrestrial objects
and 'dry-runs' at setting Autostart up should pay off :-).
