Subject:	Electric focuser for ETX-LS?
Sent:	Saturday, October 31, 2009 08:33:24
From:	Yihan Goh
Hi, I was wondering if you know of any electric focuser that would work
with the ETX-LS? There seems to be a plug for an electric focuser on the
ETX-LS itself - do you know if there are specific Meade models for this
scope? Thank you.
Mike here: JMI has one listed on this page:


Many thanks, Mike. So none of the existing Meade models would work?
Mike here: Certain none of the ETX electric focusers will work. The Microfocuser (for the LX200) might work but since I've not received my ETX-LS back from Meade yet, I can't test that.
Many thanks again, Mike.

Do you know anywhere that I can get a blueprint or assembly drawing of
the GPS unit on the ETXLS from. I'd like to see how its put together
before I make any suggestions for improvements to Meade.
I would have thought that an antenna connector for an external antenna
would have been a good idea. This would not be too hard if the Meade
antenna plugs in and is not hard wired in. Simply replace it with your
own higher quality antenna.
If anyone has ever taken one apart and has photos that would be helpful.
Mike here: I've not seen any telescope with an external antenna jack. In fact, I don't recall seeing any GPS device with an external jack. But interesting idea. I suppose if you Google for the GPS part number (whatever it is), you might find some info on the Web.
Subject:	ETX-LS Feedback - another bad 'scope!
Sent:	Wednesday, October 28, 2009 21:39:55
From:	Scott Recker (
After a week's delay (so much for "cross-shipping"), Meade sent my
replacement ETX-LS. Ser# 1019xx, build date 9/30/09. System 1.2g is
factory installed.

Interestingly, the vssver entries I described earlier are in there!
Specifically: choose "Guided Tours," you get "Tonights Best" ...
"vssver". If you choose vssver you get an error message telling you that
the "file does not exist." Also, the 'scope crashes at random times - it
just freezes, requiring a reboot. So I reinstalled System 1.2g without
the vssver.scc files, and it seems to work fine. So I guess the
vssver.scc files I found in the update weren't my imagination after all!
(or a result of downloading the update with a Mac)

Anyway, this 'scope doesn't work, either. It's a different problem than
my first one, which wouldn't find North. Now, the GPS won't find my
location. Turn it on, it starts up, starts looking for satellites
("Satellites:0"), and finds none. I tried numerous times in numerous
locations with perfectly clear skies. When I input my city and the time,
it aligns successfully, and things work pretty well (still doesn't slew
to objects very well - it's a little better after using Finder Center).

Meade agreed to take this one back, too. Sigh!

Unfortunately, that product (and -all- GPS re-radiators) are illegal
in the USA (blkhole's in Canada, so he's safe).

The US FCC bans all such devices, since they *will* mess up adjacent
(passing ambulances? low flying helicopters?) GPS signal users.

In 2007, they levied a $75,000 fine against another vendor:
(fairly far down, seek "GPS" or "radiator")

Subject:	Mini Disk for ETX-LS
Sent:	Monday, October 26, 2009 10:22:09
From:	Warren Spreng (
Sorry to hear that blkhole is having so many problems with the GPS unit.
I sent my unit in because I had fried the Autostar and could not find a
mini disk that wouldn't just shut the scope down when I tried to use it.
They adjusted my GPS antenna while it was in to be re-loaded and now it
finds the satellites in about 1 minute.  Speaking of the mini disks, I
finally received one today that I ordered from and it works!!
It is the SanDisk Ultra II Mini SD 1.0 GB.  Previously when I would try
to "Take and Store Picture" after inserting a disk, the scope would
freeze up and I would have to turn it off and back on again.  I put this
one in, did the same and everything worked fine!  Even got a picture of
my living room!  Just thought I'd throw that in for any LS users that
were having the same problem.  (PS, I had formatted each of the previous
ones with FAT32 as well as this one)

Also I thought I would comment on Meade Service.  I sent my scope in on
September 9th and they said it would be 4 to 6 weeks including shipping.
I emailed Meade after about 3 weeks as to the status and they quickly
emailed back that it should be shipping back soon.  I received it back
on October 8th.  Everyone I have corresponded with has been very helpful
and returns my emails promptly.
Appreciate your site and input!

Subject:	Possible solution for weak GPS signals
Sent:	Saturday, October 24, 2009 15:30:53
From:	blkhole (
Hi Mike I said I would do some investigating and I came up with this
solution. Cheapest way to go.

It is now possible to boost your GPS reception for your telescope GPS
even though it doesn't have an external antenna. I found this item on
the internet 

Portable Re-Radiating Antenna set (MCX) GAR08X Cost $39.90
from Pc-Mobil at

Re-radiating antenna consists of 2 parts - receiving antenna and
transmitting antenna. Receiving antenna has internal signal amplifier so
requires power. 3 x AA batteries (Rechargeable Ni-MH or alkaline)
Amplified signal is transferred to the transmitting antenna which
"radiates" the signal onto the antenna of telescope GPS. In places where
reception is marginal, e.g. in woods or streets with high buildings.
Because re-radiating antenna "amplifies" the signal so you might get 4-5
satellites when you can get only 2-3 with your handheld GPS with its own
internal antenna. Connect the external receiving antenna to the
transmitting antenna by the MCX connector, put it somewhere where it has
best view of the sky. Switch on the transmitting antenna (LED power
indicator shows it is on and has adequate battery power). Place the
radiating antenna loop onto the telescope GPS. You should see the result
immediately (allow TIFF - time to first fix).  For best result, use the
supplied rubber band to strap the antenna loop onto the telescope GPS so
that it is secure even if you move the telescope GPS about.
Characteristics and positions of internal antenna vary so experiment
with different positions to get best result. After your telescope has
finished its set up the re-radiating antennas can be removed. This does
not void warranty as you are not opening or tampering with any telescope
parts. You are just temporarily amplifying a signal so your telescope
can pick it up.

Hope this helps with some of the problems.

Subject:	ETX-LS Feedback Ver 1.2g not much improvment.
Sent:	Thursday, October 22, 2009 19:44:51
From:	blkhole (
Well Mike I am finding that the new software ver 1.2g doesn't improve
the location and detection of the GPS sats very much more than the
original software. So tonite I thought I would test it out. It said it
had to detect 4 GPS sats and just didn't do anything for 1/2 an hour. I
thought it might be the location so I got my cheap explorist GPS unit
out and put it on the telescope in the handset holder on the base. My
GPS picked up 9 sats in under 10 minutes and most were strong signals.
So the problem here is either the GPS unit on the telescope not working
well enough or the antenna that they use for the GPS unit isn't strong
enough to pick the sat signals up. The scope finds level and North fine.
If you punch in your Location and Time it does the star alighnment fine
and when you go to an object no problem. Just for a test I asked it to
find M57 from my roof in the middle of the city. 20 seconds later we
were looking at the ring nebula and had a very good alighnment and view
even though the skies were really bad with smoke and clouds. So although
this telescope does have problems with finding GPS sats (the down side)
it does give excellent views of planets and deep sky objects from very
light polluted sites. I think this scope will only start to come into
its own when Meade actually spend some time and do a real update to the
GPS software or antenna system. Maybe a plug in antenna mod would make a
difference. I'll have to see what I can come up with to amplify the GPS
sat signals.
Guy Westcott
Mike here: It is certainly possible that the GPS unit or antenna could be faulty, or even the antenna cable (assuming there is one) is disconnected (from a jar during shipping?). Unless you want to open up the GPS unit module, you will probably have to contact Meade for a repair.

From:	Bellomy, Robert S. (
Did you ever get your scope replaced or repaired??  I have been bad
about getting my situation posted online in a timely fashion.  I have
been dealing with a (at work) spacecraft issue prior to launch and it
has dominated my time.  After getting in touch with the Meade Chief
Financial Officer by email and explaining my situation to him, Meade
called me and said they were sending me a new telescope.  I did receive
it and though I didn't have much time to play with it, did power it up
and noticed it did a "fair" alignment, only off by a small margin.  I
was aware of the software upgrade to the handbox, but still not enough
free time.  Well, my spacecraft did launch this past week and so I
downloaded the new version v1.2g and updated the handbox.  I took the
scope out last evening and it aligned itself.  Although not perfectly
centered, I can adjust the AZ-EL drives to get it as close to centered
as possible.  I then took a quick tour for objects I knew I would be
able to see.  The scope did a good job.  I only hope that your issue has
been taken care of and that you are up and operating.  Like I said
before, the optics are very, very good.  The camera is interesting and I
tried it for a fixed focus wide field shot of stars.  It performed
adequately, but I will probably never use it when I have a better camera
to use.  Functionality was overall very good with all Meade's claims
being met.

Hi Mike. for those people that are wondering I've been into astronomy
for about 55 years and I always seem to find my way out of problems.
Here's what I found out. If you update your telescope to 1.2g with only
the batteries or a battery pack it seems less likely to take and more
likely to give you errors. This is what happened to me the first time.
The second time I updated I used the meade supplied power pack and had
no troubles. I think when you are updating any variance in the voltages
screws up some of the data reading and writing. Also just about any
problem can be fixed by turning off the light switch and cycling through
back to on. When you turn it back on go directly to the shut down
telescope menu and shut it down this is like putting a car in neutral
and then allows you to start all over again with a clean slate. The
manual isn't wery explicit when it tells you to put in the time and actually have to put the location in first before you get
to the time screen or at least that's the way mine came up. Will keep
you posted on any other problems that I have and fixes that I come up
with. If you want anything tried out let me know, this one has all bells
and whistles including the mini monitor.

From:	blkhole (
Hi Mike finally got a clear nite. Went out turned telescope on and let
it do its thing. After half an hour it asked me to put the time and
location in manually. Although I tried every thing in the manual I could
find no way to enter the data manually nor would the telescope go back
to shutdown mode so that I could reprogram with the new files and
updates. Finally turned it off just as it was. Put the sd chip in and
turned it back on to see if it would update. It is now in the middle of
updating. It has now updated and asked me to remove the chip and

I might also add that my telescope has the same white piece in the card
slot as Gregs does. I found that this is just an indicator showing you
which way to put the chip in.     Cut away on the adapter to the
bottom...white arrow to the top and fingure connectors facing out
towards the side of the on off switch.

I am now going to restart the LS keeping my fingers crossed. It restarts
at ver 1.02 but the handbox says Time and Location on the top lineand
get from GPS on the second line. Only button that does anything is the
media button and that just starts the media presentation again Back
button and mode do I can't even get the telescope in the
shut down position. I'm starting to think that this is a white elephant
and not such an easy telescope to use even for advanced amateurs.

Guy Westcott
Mike here: The latest version of the AutoStar III software is 1.2g. I don't know why you are seeing 1.02 after updating to the current version. Up until recently, ETX-LS telescopes were shipped with 1.07. I suggest reformatting the mini SD card, re-installing the software on it, and then re-install the software into the ETX-LS. Thanks for the info on the card slot.


Yes Mike I just checked it again and it definetely is saying Ver 1.02
not 1.2g The download onto the chip and into the telescope went ok
software file is called EFINDERETX and is five folders and two bin files
(firmware and the FlashFirmware) total size is 243 Meg. The telescope
arrived with Ver 1.07 but after not finding the gps sats very well I
updated. I wonder what others are seeing as to version on their handsets
after updating?

And an update:

Just redownloaded and burnt a new sd chip and reprogrammed it this time
it came up as Ver 1.2g so maybe now it will lock on with the gps and
other processes a little better. Told it to goto Jupiter and it found it
ok. the optics are very clear and sharp for a 6" used a Xcell 18mm
eyepiece and could see the cloud bands and details easily. So first
light worked well you watch I'll get another week of rain and clouds
now. Thanks for the help Mike.

Did you get a replacement for your ETX-LS yet?, I am hesitating doing
anything yet partially because of the weather and being worried that
upgrading it to the Version 1.2 might make it worse.

Did you try using the newer version of the software before you sent your
LS back to Meade?

It seemed strange that at one time and one time only my LS did
everything it was supposed to do and this also makes me wonder if there
were certain situations present that either helped or hindered the
proper alignment of the LS.

To know that there are others having similar problems like I do makes me

I might also have a solution for Hajri Mohammed's problems. If his

the adapter. I have also found that it is easier to leave the adapter in

easier to get the micro chip in and out. The other way he could go is to
get a standard SD chip holder out of an old camera and replace the mini

if it's good should be able to do this for him at a price less than

I purchased the new ETX-LS ACF and agree with every thing you say. But
there are a few items that Meade should deal with. The SD slot on the
telescope is a Mini SD slot and not a standard SD slot The mini SD chip
however went out of popular use about a year ago and they are very hard
to find. You can always fit an adapter however but getting the chip back
out is extremely difficult unless you are female and have long nails.
Also no mention is made as to whether the scope will accept SDHC chips,
THIS SHOULD BE IN THE MANUAL. Meade could have easily supplied an SD
chip with the scope. When I phoned and asked they were more interested
in selling me an extended warrantee than correcting problems.The scope
should be supplied with the AC power adapter, not everyone has a stock
of batteries around their house. Meade does not at present make a carry
case for the telescope but for $375 JMI does. No 2 optical back, this
would have been nice. Given the option of a finder scope or a red dot
finder would also have been nice. One major change that Meade gets
points for is that now all their accessories have the same thread patern
as Celestron this enables me to use a vast collection of bits and pieces
that I have accumulated over the years. On the whole I liked the
telescope it performed well after I updated the AutoStar to Ver1.2 at
212mb (this refined the GPS tracking) A bit expensive for the begginner
but for someone older (retired) and hard of seeing to line things up,
its ideal.
Mike here: Adding the AC Adapter as standard would have increased the price somewhat. And not everyone can use it. So having it as an option is probably still appropriate. The SCT adapter thread is a standard across many manufacturers including Meade and Celestron. So most SCT accessories should work with the ETX-LS. Your concerns about the mini SD card are valid. Sometimes decisions are made early on in a project's design stage that get left behind as technology moves on. Only a few manufacturers (like Apple) can lead technology changes rather than lag them.
