Im just getting my first scope (10" dob) and starting to think about additional bits such as eyepieces and filters.
I will probably want a high mag eyepiece ( say a 4mm) but have seen there are zoom ones available ( not 4mm) and just wondered if they were any good. I assume a non zoom is probably better from a pure optical perspective but the zoom would be convenient...
Anyone had any experience with the zooms?
