Most of my nonsense from the asi071 is here
https://www.astrobin.com/users/ChrisFC/

I use both an 8" F5 gso and and 80mm F5.9 WO refractor on a CGEM mount. I think the imaging scales are about 0.9 and 1.6 arcsec/pixel. I particularly like it with the newt.
Guiding 50mm zwo guidescope, phd2.
Capture with SGPro. I use the standard unity gain setting this ascom.
With a UV/IR filter the optimal sub length is 60-90sec (to swamp read noise). Can share my spreadsheet calculator for this.
With the STC duo filter I use 6 min subs, although longer is probably better on some targets.
I used to cool to -5C. But now just to 0C. It doesn't need as much as CCD sensors as the dark current noise is so low.

For processing I don't use bias frames. Not needed!
