Gee that mirror in your scope is good. Such great fine detail.

Yeah, I think it is ok..? (definitely for imaging anyway
)

You are spoilt as several years ago you wouldn't've seen all that fine detail to even know the seeing was off!

Certainly not in
THESE days

My personal opinion is to remove the really bad ones and do a stack and see. I sometimes do a few stacks to see what it looks like with the not so good left in and a stack with them taken out. Often I like the ones with the not so good taken out. Its less important with the colour and more important for the luminance.

Agree and this is essentially what I usually do too and yes colour can be taken in poor seeing, wind and even through some cloud and while it can't then be used in the Lum stack, it is perfectly ok for the RGB. Only a couple of times has the seeing been so bad that it affected the RGB combine and that was only for one colour each time. If the seeing is looking bad I often revert to grabbing some RGB...just not as cool seeing this come down at those times

That's why we opted for 12 inch F3.8 scopes with sensitive cameras and good tracking to get the maximum amount of signal in the least amount of available time. Think of the other poor souls imaging at F8 and beyond - ouch!

Some still think that 30min subs (or more) are a must but this is only because the camera they use, plus often coupled with the F ratio and/or small aperture, requires it
(Just ask Ray
)

12 inch F3.8 imaging is definitely a luxury once you get all the alignments/flex all good.

Yes, I have not had to fiddle with the AG12 since purchased in 2011, in fact I have not adjusted anything nor collimated it since Aug 2014 when it went into to the current observatory! (nor have I had to tweak the PA!)....only thing that has occurred since was one tiny grub screw came lose on the small brass transfer gear one night on the NJP and the hex head had rounded so I couldn't tighten it hard enough with an Allen key...a 30c fix the next day

Perhaps one of these ZWO ASI1600 and 60 second lucky imaging
to grab the moments of good seeing is in your future. Its taking the ICX694 and 12 inch F3.6 to the next logical step forward.

Well actually, I did do essentially this for
