This robust 18" fork mount Newtonian f 5.2 is being sold by the Oil Region Astronomical Society , in Venango County, Northwest Pennsylvania. Our moving to a new location has prompted it's selling. This telescope has a rich history. It was hand crafted by a German Engineer in Michigan as a prototype for a larger instrument going into one of the universities. The instrument is very solid and weights about 2500 pounds. ORAS Club President Tim Spuck recalls "the first view I had through the telescope was of Jupiter. You could see clearly Io crossing in front of the planet with and Io's shadow on Jupiter. It was impressive! The next thing I saw was the Orion Nebula ... the first time I saw the vivid green color of the nebula. The instrument may be older, but the optics produce some of the best views of both planets and deep sky objects I've seen through a telescope"
It comes complete with its 18" mirror with carrying case, as well as the secondary mirror and drive motors. The Oil Region Astronomical Society used the 18-inch telescope for a number of years, and tried to automate the scope. We added stepper motors and an additional altitude gear to the telescope. The altitude gear alone is a 24" high precision brass worm gear was precision machined at a local commercial heavy equipment fabricator, and is truly a mechanical charm. At the time we had it made, to purchase one commercially it would have cost us about $7800 for the gear and worm alone. After dealing with several visitor's who were afraid of heights, we made the decision to replace the telescope with a Schmidt-Cassegrain to keep the eyepiece closer to the ground. We would prefer to sale the telescope or part out the gears and optics. . This classic is being sold as is, and of course, we are flexible with regards to a date of pick-up. Club members would assist in the loading of scope and mount, including a lift. We would be overjoyed and most appreciative of that(those) individual(s) who would preserve this heirloom for another generation. We are in Venango County, Pennsylvania and you our welcome to attend and participate in our annual Astroblast Starparty being held this week, and well as inspect the scope if you wish. Our Autumn colors are now starting, and indeed we have dark skies.

Based on the size of this instrument, actual pick up of all scope components would be best
