Clouds have been lousy but I finally caught a break a few nights ago. I waited 6+ hours after setting up for the clouds to clear and caught 100 minutes of the comet. Transparency was terrible so I ended up shooting 240sec images to see details. Didn't have too much time to test so I just stuck with what looked good. Hoping to get another shot in the coming days to retry (probably will do 60-120 secs at max).

 

Equipment used:

  1. Astro-Tech AT60ED with the 0.8x Reducer/Flattener on Advanced VX Mount
  2. Mount controlled via Astroberry
  3. ZWO ASI533MC Pro
  4. Svbony 60mm guide scope with ZWO ASI120MM-Mini guide cam
  5. 25x240sec with L-Pro
  6. 15 darks
  7. 30 flats for each session
  8. 35 bias
  9. I stacked the Comet in AstroPixelProcessor and stacked the stars in Siril to try and just get the stars stacked. I then made a composite in Photoshop.

I also have a short timelapse of the comet zooming through the sky and some more info + my process in this video: https://www.youtube....h?v=-ApH5fxkWBI
