I'm not new to imaging but not an expert. I guess I'm somewhere inbetween. I'm just getting back after about 10 years away though and some things are vague. My old QHY8CCD seems to have little to zero support anymore. I tried and tried to get my camera recognized the past 2 weeks and couldn't. After a lot of digging and reading similar posts I decided to get a new imager and shelf the old QHY8 for now.
So I ended up replacing the QHY8 with an ASI294MC Pro. Also bought an ASI120MM Mini Guider. Updated all Ascom and EQMOD software and drivers, got Cartes Du Ciel installed and PhD 2 and so far everything is talking. Also installed ASI Studio. I was out last night (yes, new equipment and still had stars but a few clouds) and everything worked great except for my lack of focus vigilance. Still, guiding was best I've ever had. Goto's are right on and the hardware all seemed to work great! I already built the Dark Library in PhD 2 for the Mini Guider as it prompted me to.
So now I need to build a Dark Library for the ASI294MC Pro and not sure where to start. I did a search and I still didn't see what I needed so here I am with a question that's probably been asked 200 times. With the QHY8 I don't think we even did darks so my experience with using darks is limited in the first place.
I guess the first obvious question is, should I build a Dark Library for the ASI294MC Pro?
Secondly, do I need to build a set of darks for everything from 1 second up to 900 seconds (for every possible exposure time)?
Third, how many darks do I need for each set?
I have not modified my Cloudy Nights profile information yet, it's many years old so please don't look at that. Some of it is obsolete now. I'll get that updated today.
Thanks ahead for any help.
