Hi -
I posted this to the solar system forum the other day - thought I would share it here too. This is Roland's 10" f14.6 with a 23% central obstruction set up on an A/P 900 mount and portable pier. I often mount a 4" traveler on the top dovetail bar for star parties - the contrast in focal length is great fun visually.
This is my primary planetary imaging platform - I use a Baader FFC or barlow for focal lengths from 7-12 meters, depending on the subject. Shown here is a 1.5" travel starlight auxilliary focuser which is a nice convenience for critical focusing on our coldest Buffalo winter nights.
