I bought a 5" reflector telescope for Mars observation in summer 2003.
It was delightful ... My apartment of that time had a perfect south-
facing porch with a clear view of the entire sky-track that Mars
made. Once it was up 40 degrees over the horizon, I could spend hours
studying it. At 80x-110x magnification, I could make out atmospheric
and surface features.
At 80x magnification, it took about 22 seconds to traverse the field
of view of my telescope (simple Dobsonian mount) before repositioning.

Best,

AND, "At a modest 75-power magnification Mars will look as large as
the full moon to the naked eye.."
Heck of a diffference between a size of 34.6 mm and the size when
viewed thru a 75X scope!

Rob,
I read that on Aug 27th, of this year, Earth and Mars
will experience their closest proximity in many
centuries.
Article states that Mars should appear Moon like in
size at 34.6MM and that this distance relationship
"may" not happen again for 60,000 years.
Get your TCs ready to stack onto the 300mm f2.8.;-]
In 60K years photo resolution will be such that a
Pentax 50mm lens will render resolution to allow one
to simply pull up the image in PS to examine the
planet's surface.
