12.5" F4.7 Newtonian for Gary in Hinckley, OH.:

This telescope includes an Antares 2-speed 2" crayford focuser with 1.25" adapter, a Destiny curved vane spider and secondary. The mirror is a Hubble Optics 12.5" F4.7 with a strehl of .9987 and sits on a custom build 6-point all aluminum mirror cell optimized with Plop. I've installed the encoder installation kit and encoders for Gary as well as a DSC stalk for a digital setting circle.
 
The telescope was completed in June 2009.
 

This picture of the moon was taken with the 12.5" telescope. I used a TeleVue 12mm Nagler and a simple point 'n shoot Nikon digital camera. More photos here.

The 12.5" completely assembled and ready to use.
