Reflectors eventually need realuminizing, but very seldom. My own personal
preference would be an F/8, but I would also prefer an equatorial mount. There
are lots of reasons for this that are too extensive to go into here, suffice it
to say that for finding, tracking and for high magnification, a well-oriented
EQ beats the pants off an altaz. I will probably get flak on the F/8, but a
lot of people think that only a short F/value can see DSO's, which is not the
case - you just need longer FL eyepieces.

Clear, Dark, Steady Skies!
