Hello,
I am Patrick from south-west of France.
I wanted to buy a monochrome cooled camera for my AT111EDT. My budget is about 1000$.
In this envelop, here in Europe, there is the 178MM or the 174MM. None of those cams satisfies precisely the sampling rules. But is it really important to satisfy precisely those rules as the turbulence will flatten all. And maybe it would be better to oversample than subsample.
My targets are galaxies, planetary nebulaes, and planets.
For the wide field I wonder to use photographics lenses.
So, what are the arguments that can help me to choose between 178MM or 174MM ?
Thank you
Clear skies
Patrick
