That is the question...? answer?..move to the Atacama

Gee that mirror in your scope is good. Such great fine detail. You are spoilt as several years ago you wouldn't've seen all that fine detail to even know the seeing was off!
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.
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!
12 inch F3.8 imaging is definitely a luxury once you get all the alignments/flex all good.
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.
