For Sale: 32" Optical Guidance Systems Ritchey Chretien Telescope

For Sale: Optical Guidance Systems 32" Ritchey-Chretien Telescope, including Optical Tube and OGS140 Mount.

For over a year now it has become increasingly obvious to me that I no longer have the time to devote to the use of this magnificent instrument, and have little prospect of that changing for years to come. I have decided, therefore, to place it for sale so that it may find appropriate use in amateur, educational, or professional use.

If one were to purchase this scope and mount new, the price would be over $300,000. I am listing the OTA for $275,000, and including the mount as a bonus. (I won't have use for the mount after the OTA is gone.) Buyer will be responsible for pickup of the scope from its remote Northwest Arizona location.

This scope has produced hundreds of marvelous images for me, including a nice collection of APODs and a huge number of magazine and book published images.

If you have the resources and time to acquire an instrument of this size and quality, you can save years of waiting for a new one to be manufactured, and get a proven performer immediately.
