Why are we even building new space telescopes ? Time to tell the space agencies ! Congratulations Ignacio ! 🤩 Sébastien De : main@ap-gto.groups.io <main@ap-gto.groups.io> de la part de Roland

Congrats again Ignacio!

Wow! This one is incredible. Congrats Ignacio!

It was not likely the mount. Lets assume for a second it is not the mount, what would be next on the list? Drawtube moving would move the star on the frame as well. Have you looked at that? If so how?

Not a guiding issue as I'm not guiding. Since the absolute encoders didn't log they detected any slew or directed movement, then Ray's theory of slippage of the clutch makes sense. I'm not sure how

Hi Brian, I am working on documentation for the new release. There is an older video on my website that should help. First clear night, I will also make a quick start video. The most common trouble

I always check my executables before uploading with VirusTotal. There were no detections against all 67 anti-virus vendors.

No hurry and thanks for excellent explanation. Peter

Yes, it's quite smooth. I don't have any pix at my disposal at the moment, but will dig some up when I get back. Rolando

FYI If you have Norton/Symantec as your virus checker on downloaded files, it will quarantine SkyTrack and flag it as WS.Reputation1. This is NOT an actual virus. This is Norton's designation for a

OK. Without encoders and using spur gears, I assume PE would look somewhat sinusoidal. Peter

Yes. With encoders it looks the same as the Mach2 with encoders. Without encoders you have PE but without belt ripple. Without encoders but with PEM activated, you have low PE and no belt

Do you have a similar graph using spur gears instead of belts like from A-P1100GTO mount? Peter

Actually the graph below shows belt ripple + stepper motor ripple + periodic error. The stepper motor ripple is very small but shows up as tiny wiggles on the belt ripple. The periodic error is the

I didn't realized you were comparing encoded mounts to non-encoded mounts whether gear reduction uses spur gears or pulley belts. Yes, absolute encoder mounts beat everything else especially when

I'll answer both your questions. 1) .02 seconds at 1x sidereal is .02 x 15 arc sec per second = 0.3 arc seconds 2) if you didn't know at this point, I would like to make clear that the Mach2 is a
