Seeing vs Aperture
Not wanting to hijack Mike's Deep Sky image thread, I did make the observation of larger aperture being a bugger when it comes to seeing.
I have only been blessed with a handful of nights where I could truly say
my 36cm aperture was producing razor-sharp imagery, yet my 13cm aperture scope performs very well on most nights.
For those newbies who are interested there was a good write-up on this subject by Andrew Young at JPL in the September 1971 edition of Sky & Telescope.
Young noted "the aperture must be matched to the seeing conditions"
and I have to say I agree with him....but am curious as to whether others
have not found this to be the case.
