I use my questar mostly for bird and geology photography> It has one of the greatest means for image stabilization (I have a Q-7 Ti) with an after market "steady cam" lens gizmo made by Canon. Its a real great tool for long distance range shots and it helps moderate the atmospherics when Im shooting "peneplain surfaces' at over 5 miles distance. I rarely bother pointing it up unless theres something extra going on (Ill certainly be watching this comet , but I was a kid when Kouhoutec came around and was really bummed out when it turned out to be a visual dud)
As far as my use of the instrument,I am compiling photos for a geology book and Ive used it to set up pan shots of distant structures that can only be appreciated in long distance. In my camera Ive got "Stitching" software so I can adjust the spread of the shot.
I got mine at a schools de- accession sale so if you dont mind Ill drive my "Ferrari" knowing that I made a great deal.
AS Ive told Ragmanoccasionally, the proof is in the picture, not the equipment. My goal is shots, how I get there is of no concern to anyone save me. Most all spotting scopes are pretty crappy no matter what the ads say. Ive rented and leased all kinds over the years and was mostly satisfied with some of the canon or Nikor long Fp lenses but I wanted something I could leave "on station".
Gotta admit, I dont hardly use the clock drive mechanisms . Only times Ive used em is when I would do a loong exposure of something like the milky way from Spruce Knob W Va. Otherwise, I suppose I could do without it. Now with this comet, assuming it aint another dud, Ill be able to stay on station pretty well.
