How do you find the UHC filter? Have you tried a OIII filter?
What objects do you normally use the UHC on? Do you use it at home or at a dark sky or both?
Oh and if we're talking favourite objects, not favourite DSO's, then Saturn has to be at the top of the list!
There's nothing quite like looking at Saturn..
I'll always remember my first viewing of it through a telescope.. it definitely got me hooked on astronomy from then on.
