Description

Details

Parallax Instruments PI250C 10" Classical F/15 Cassegrain Telescope

Parallax also offers Classical Cassegrain and Dall-Kirkham Cassegrain telescopes in 10", 12.5", 14.5", and 16" apertures. The Classical Cassegrain offers a very long focal length in a relatively compact tube. Includes 2" Feather Touch or 2.7" AP Focuser (Specify), 8X50 finder, standard tube rings, tube weight counterbar assembly and slewing handles.

All optical tubes are finished in high gloss acrylic urethane paint and are furnished with metal snap-lock dust cover and 2" and 1 1/4" focuser adapters. Diagonals or eyepieces are not included. Interferometric test report and fringe analysis data is included with each telescope.

They are excellent instruments for high magnification planetary and double star work. The Dall-Kirkham Cassegrain with its F/20 focal ratio and smaller central obstruction is perhaps the ultimate high magnification visual planetary telescope. Enhanced aluminum coatings for the Parallax Instruments PI250C 10" Classical F/15 Cassegrain Telescope are available for an additional $120.
