M65 & M66 taken over 2 nights: 25/26 Feb 2019
Modified Sony A7S on Celestron C11 with Starizona LF 0.72x Corrector
6.5hours of data in 30sec subexposures - yes that's nearly 800 subs!

That's wonderful Mark ! If any criticism, and to be really picky, I would say, given how smooth the data seems to be, that it could possibly take a bit more sharpening. I especially like the detail in M65, and the reason I think it could possibly take a bit more sharpening.
Edit... 800 subs ! that must have taken a while to process especially as, I assume, you drizzle stacked it !

Excellent Mark, Great detail and colour.
I think I agree with Robert that it could take a bit more selective sharpening, though still great as it is.

:! !!!!!!!!!!!!!!!!
Wow, you must have a very good computer. I recently downloaded a whole load of Roger's CMOS subs and it really overloaded my computer, I was glad to delete them again. But I guess mine is older and less good spec than yours.

That is really wonderful hubbly jubbly image. Loads of lovely detail and excellent colour without overdoing it. When you look around there are quite a few tiddly galaxies in evidence as well. Lovely.
Lovely picture Mark and to think that there is (in simple distance from Earth terms) 6 million light years between them!
Hugh
Lovely detail on the galaxies, well done Mark.

It might take a tiny bit more deconvolution but I was trying to keep the noise artifacts under control.
Yes, 800 subs took ages to calibrate and integrate - especially using my usual 2x drizzle. I reckon the calibration, stacking and drizzle stacking took around 6 hours.
