Schmidt Cassegrain’s can be very heavy.
I bought a used one with an 8” or 12 “ mirror, (don’t remember now) and it’s so heavy mr. mm has to lift it to set it up.
I had a plain old 6” reflector and it was awkward. LONG tube but easy to collimate.
I also have a 3” refractor but it just doesn’t seem to have the magnifying power but is the easiest to haul around.
I’ll be working from my back yard, so the weight won’t matter much.
I’m also thinking of a larger Newtonian, since travel isn’t a factor.
