Hi Ralph,Before I attempt to track a sat, I perform a basic test. I test my scope's setup. It is a simple procedure that will insure that I have my location, time and date, correct identification of alignment stars, etc. , all entered correctly. It does not involve the Satellite Tracker Program.I want to see the scope "GOTO" a star (or stars), a planet, the moon (if handy), with the target appearing in the field of view. I will wait several minutes on each target to confirm that the scope, is in fact, tracking the target (it should appear reasonably motionless). An additional preparation for a sat track attempt is to insure that fresh elsets are loaded into the Satellite Tracker Program.The scope doesn't know the difference between targets. And the only difference in the "command pulses" sent to the scope is that the sat track's are "fast and furious". If it then occurs that the scope acquires the satellite target but does not follow it, the program/computer is not sending the same type/form of "Command pulse" (if any) to the scope. Now if your scope goes to a star, planet, or the moon correctly, and then the target drifts slowly out of view, the problem is with the telescope.The above rambling is based more upon reasoning than any actual technical knowledge

I did track several satellites but I never caught any on camera because either the scope wasn't well focused or the image sensor was too small for 2500mm focal length. The satellite was most likely not properly centered in the field of view.When I tried it this year, the only things that are different is the fact that I now set an altitude limit, updated the satellite tracker software, and ASCOM Platform. All else is just the same as it was 2 years ago.Ralph

I don't have experience with the GPS Meades, but in the years past I have been extremely successful in tracking satellites with my 8" LX200 Classic. Remote diagnosis of your problem may prove difficult for even a LX200GPS expert.I assume you get the telescope oriented to point where you can "GOTO" planets, stars, the moon, etc., with a reasonable expectation (9 out of 10 times) of having the target appear in the field of view of a 40mm eyepiece?Also, previously, the same day, you had downloaded new (what were they called) elsets?. And you have also replaced the old elset file with the new data?After the above, I believe is when I hook up the cable between my telescope and my laptop. Then I think I opened the Satellite Tracker software, selected my site, opened the elset file that contains today's elsets,, checked to see if the file actually opened in ST, and see if the ST program recognizes that a LX200 was connected to the telescope. I have no idea if those steps are required with the GPS scopes, but it could be similar. Trying to remember, but it's been 2 or 3 years.I know that the above rambling won't tell you what you are doing wrong, but it will take you up to the stage where you should be able to track a sat.Several years ago, with the assistance of some of my neighbors and their kids, we would do marathon tracking. I would work the laptop, one of the "skilled at video games" young'ins would man the finder scope while holding a joystick. The job of the finder scope position was to center the finder scope on the sat, which is easily found in the finder, even if not in the field on the big glass. Others, adults and kids, would take turns manning the main scope eyepiece. The job of the eyepiece position was to call out "yes, there it is!" when the saw the sat.I would immediately select a new satellite as a target, and we would repeat the process. We had a success rate of about 95%, and on several nights we would run at about two sats a minute. After 2 hours we would bag over 200 successes, I believe once we went for about 3 hours with a score somewhere over 300. I believe the original Satellite Tracker Software was developed expressly for the LX200 Classic telescope.This post has triggered an "Off Topic" question I have for any moderators or owners of this site that might read this post. The question is: Do the current owners/moderators have access to early site records that might identify when individuals joined, signed up for, or downloaded, or ordered, the Satellite Tracker Program. My name is Robin Wier, and my email addy back then was probably rwier@.... They later became concentric.net. I wonder how close I was to being a charter member, so to speak.Thanks,RobinRobin
