Interesting idea. I might try and do that.

Steve,
P.S. I ditched flats too, but that has more to do with your specific optical thru-put that a camera noise issue.

Re: ASI2600 - Darks vs no darks
Flats are a must in my situation as my optical path produces a fairly substantial vignetting. And, those dust motes on your filters will get you every time. The one time I didn't take flats on a wide field nebula was the time I spend hours removing the dust donut manually with graphic editing tools.sdbodin wrote: ↑Sun Jul 11, 2021 6:19 pm Good to see that someone else is experimenting with no darks. I did all my spring snapshots this way. Sure is quicker and with less unexpected results.

Re: ASI2600 - Darks vs no darks
Yes, vignetting was what I was getting at. That brings up the problem of too big a chip for your scope, all that 'megapixel, full frame hype' that the newbie falls for:XCalRocketMan wrote: ↑Mon Jul 12, 2021 2:06 am

Flats won't fix this!!! Dust motes are a problem for anyone who is imaging in the 'outback' while on a trip etc.. Luckily I have little dust problems being sheltered and, maybe, too anal about cleanliness.
Good thread, much to discuss on this subject,
Steve
