Hi and welcome to both Quack and Luka..I brought an 8"inch dob as my first "real" scope..it has taught me a great deal about optics (collimation)...eyepieces (diffrences in magnifcation and quality of images)...and a great deal about patience when trying to find objects of interest (steering the scope using a very smooth and refined manner).
Definitely a great scope to use and to learn the sky from!
Cheers!
To me they all look very similar with small differences in pricing ($450-$550) and supplied eyepieces/focusers. Any particular thoughts which one to get/avoid?
I can guess that 2" Crayford focuser is desirable as the last 2 scopes have it and cost more.
