One more example to make it as last to finish the camera topic here
This image of Rosette, with two Takahashi scopes and two cameras one of them is a full frame camera DSLR, done for 12 hours:

And here is another one with also another Takahashi scope and smaller sensor for 5 hours 32 minutes:

I will choose the second one always.
So, the camera topic isn't really entered my mind as people buying expensive amazing scopes and yet to buy a better camera larger sensor with it, so camera thing is not a factor here, and even if people will lose light percent gathering it didn't stop them to use those small sensor cameras, thus a camera thing is not what they or me worried about, and i won't afford any astro cooled full frame camera an soon in future, and APS-C mono could be my next year plan, but i can't wait until next year to decide which scope only after i buy that camera first.
