Re: Unexpected mount movement
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?

Re: Unexpected mount movement
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

WoW! Another APOD for Ignacio
https://apod.nasa.gov/apod/ap211014.html
With his 168mm refractor that I made from some one-off glass I had on hand. Maybe I should make some more of them?
Anyway, congratulations Ignacio. You are

Re: Testing SkyTrack continuous tracking with the Mach2

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.

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

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

Re: RA Mesh adjustment for 2104 model Mach 1 GTO
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?

Re: RA Mesh adjustment for 2104 model Mach 1 GTO
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

Re: RA Mesh adjustment for 2104 model Mach 1 GTO
Unfortunately rms is not a good representative of tracking because it basically smooths out peak excursions that can leave stars eggy or having small appendages. I would rather have consistent 1 arc
