Re: Since we are talking about low light performance...

A fascinating study, David.

I'm not sure if I understood you completely... did you actually try stacking the SD1M images?

I was under the impression that the SD1M makes a dark frame exposure for shutter speeds 30 secs and over but I don't know how you would access those frames. So I imagine that you would have to take your own dark frames anyway.

I've been planning on using my GFX 50S II for astro work, but I haven't done so yet. The longest lens I have is the 100-200 f/5.6 which is probably a bit slow.
