I really should be saying my favourite is the 4" Reflector I made back in 1984 because it was my first scope and gave me all my first breathtaking views and because I built it myself,
or my 12" Dob Autographed by John Dobson because it finally allowed me to see all those faint little fuzzies with ease,
but I do honestly prefer my
ED80.
Not so much for visual as I don't believe it is a great visual scope, but for it's fantastic astrophotography potential.
Toucam, DSLR, and now AstroVideo, it does it all well. And they are cheap
