Subject:	#505 cable and software

From:	Graham Hilton (
I'm a new owner of an etx125 which I bought in Florida while on holiday
and brought back with me on the plane to the save a few bucks!

I have just made a cable to connect the Autostar to my computer and
everything is working fine  with upgrades etc.

I wonder if it is possible to obtain the software which comes with the
complete package separately please?
Best regards

My software is now available for download from the astronomy section in

Click on the Astronomy leaf in the top frame.

The NTC download is pretty old but is the last stable version. I've been
working on the mapper program, but will continue testing the newer
version of NTC which includes a search function for locating a object
that isn't visible when you replace the eyepiece with a camera.

The main problem, which has been solved during development of my Mapper
program, was accurately adjusting the lines of longitude. The longitude
problem also affects NTC.

Things are working well using my ETX90 thanks to you.I was wondering
which planetarium or skymap which works well with ETX 90 on the PC ? A
simple one to download perhaps? I got Starry night bundle when I bought
the cables #505, but the program won't connect to the scope.I've tried
several times
Thanks a lot again!

Subject:	Control of ETX 125 with Astromist software through palm device

From:	alain verschuere (
Are you aware of the usefulness of this (Astromist) software through a
palm device to control the ETX-125 scope. Astromist seems to be a nice
program.  Any users yet (especially interested in the control features)?
What would be the (dis)advantages over the autostar.
Thank you in advance,

Hi Sure could use some assistance here.
System: Meade ETX 70 with the 494 Autostar control.
Software: # 506 AstroFinder package. (ACP 1.2)
Hardware: ETX 70, Toshiba 3005-S303 Pentium 3.

Problem. Regardless of repeated checking I can't get the computer to
talk to the Autostar.

When I bring up the control panel for the ACP I get the following panel

These data are all in RED color and impossible to change. When I
instruct the device to set the time to computer time, I get the error
message : Illegal time, check your computer date and time. The computer
date and time are correct. For some reason the computer can not access
the hand held control. I have no serial connection on the lap top so the
USB connection seemed reasonable to me. Is there a known problem with
this set up. I checked the continuity of the connecting cable which was

Mike here: Have you contacted the developer of ACP? I don't use it so can't answer directly. But if not the current version you might want to download a new version from their website.


Thanx Mike

 I'll give it a go.

The ASCOM platform lumps them all as "Autostar"

(they may have a separate entry for LX200gps, since some
of its conventions differ from the classic LX200)

Thanks much Dick.

Clear skies!!!

Thank you very much Randy.  I'll use the LX 200 with Autostar setting. 
Good to know about the COM port.  My notebook has only USB so my adapter
should make a connection OK.

Hello George,
My name is Randy Miller, and I'm located in SLC, UT.
I use Starry Night with my ETX 125 and use the LX200 and Autostar
setting. I've had it running for some time now and I remember I had some
COM port issues when I set it up that caused me some grief. I picked up
a USB to serial adapter and that made things somewhat easier. If I can
be of further assistance drop me a line.

From:	John (
As you know I am using an ETX90EC with Starry Night Pro and ASCOM
telescope control. The Starry Night Manual advises using the "LX200 with
Autostar" option for any ETX series scope, and this works fine for me.

I am controlling my ETX 125 using StarryNight Pro 4.5 (ASCOM
platform)(actually v.4.5.2).

Use the LX 200/Autostar option. Works like a charm.

Make sure you have good location/time inputs use a GPS patch if

Biggest problem I have is making sure I click (enter) the right
alignment star. Sometimes it is not so easy to figure out which star you
need to move to.

Good luck Chuck Nardo

From:	B F (

The Starry Night Manual does state to select the LX200 option for all
ETX scopes. And it works fine for me.

Do you know of anyone who is controlling an ETX 125 by computer from
StarryNight Pro 4.5 (ASCOM platform)?

If so, what scope was selected?  ASCOM doesn't list the ETX series.

All else failing, I'm going to try the LX 200/Autostar option.

Mike here: I'm sure people are using it. I don't have SN. Have you checked their website?
