0.81-m Tenagra II (32″) Telescope Specifications
This is Tenagra Observatories’ flagship telescope. It is an f/7 Ritchey-Chretien. The science camera is 2048 x 2048 x 13.5nm back illuminated E2V chip yielding ~0.98″ per pixel binned 2X2. Field of view is 16.8 X 16.8 arc minutes. Chip temperature is maintained at a constant –50° C. year round. Even more remarkable, exposures of up to 800s can be taken without need for autoguiding. A highly accurate automated refocus occurs with every telescope slew.
Paul Jones has made hundreds of Ritchey-Chretien systems and this is probably one of the last 32” systems produced. Clausing performed the coating.

Telescope Control System
In 2008 it was time to replace legacy hardware and software. It is now 100% ASCOM compliant (from Astrometrics, Inc.).
The telescope is in a 14.5’ Ash dome which has been modified for continuous usage: (a) control of the upper and lower shutters is via monorail contacts and (b) the dome is rotated by a large stepper motor. Both control systems, of course, are under manual or software control.
