Hi all,
I would like to provide an update on my eccentricity issues. Hopefully you will be in a better position to help. I re-centered the image in the guide scope, and re-positioned the guide scope in its bracket. Stars look a little better (maybe).
- Shorter subs have rounder stars. At 1 minute, stars look great.
- Elongation rotates with camera.
- Polar alignment seems good.
- Guiding overall is good, although RA is worse than dec. Eg: RA 0.6, dec 0.4.
- RA pulses are up and down. Dec pulses are always down for some reason.
Any additional suggestions are welcome.
Many thanks,
Stéphane
