I remembering bringing my 5" dobson to a work retreat camping trip. Everyone was pretty boozed up to the point where they were struggling to keep their eyes steady in the eyepiece.
When one of my coworkers finally got everything lined up he just blurted out “HOLY FUCKING SHIT THAT’S SATURN!”
It was great.
I think you’re mixing up names. Dobson is the name of the mount, and since they’re most commonly used on Newtonians, it’s kind of become shorthand. My 5" and 12" are both Newtonian reflectors on Dobson mounts.
Maybe you’re thinking of a Schmidt Cassegrain?
