Telescopes

I'll always have a soft spot for the 3" Newtonian telescope that I received when I was 10. A couple of years later I moved to northern Arizona near Lowell Observatory where I fell in love with the spectacular skies.

Orion XT-8 Dobsonian

I now have two telescopes. I mostly use the 8" Dobsonian Orion XT-8 from home. It's a great visual telescope, easy to use, but bulky to move.

Questar Standard 3.5"

The scope that I use the most is my smallest. I use it for both visual observing and astrophotography. A 2013 Questar 3.5" standard, with broadband coatings and Zerodur primary (the same as used in the Hobby-Eberly Telescope). The telescope, eyepieces, camera, mount, and a small tripod fit into a carry on case and weigh about ten pounds. I normally use it with a heavy duty camera tripod and a wedge that I built myself. Setting up and aligning the scope for astrophotography takes about ten minutes.

The Questar is a treat. It has no "go to" drive or modern electronics, but its setting circles are large enough that it works nicely in "push to" mode. The control box at the back with built in finder, Barlow lens, and a dedicated axial port for a camera make it a pleasure to use in the dark. its high quality optics, guaranteed to be 1/8 wave end to end, are a great match for modern digital image processing algorithms. Finally there's the fan-boy thrill of using a version of the 1st telescope sent into space (Gemini 4) and one owned by Wernher Von Braun and Arthur C. Clark.
