Is 16” a respectable aperature for viewing DSO with a dob? Is there that much difference at the eyepiece when compared to 18-20”?

16" is a great aperture for DSOs. The next logical step up would be 20"
Once you go past 16" then 2" steps are not that noticeable.
I would rather a excellent 16" than an ok 18 or 20.
There can be a huge variation on the actual bulk of scopes of a similar aperture. A well designed 18 or 20 can be more compact than many commercial 16s.
I would vary the saying to "Good quality aperture is King"
