GNTO On-Site Equipment
Imaging Telescope
The imaging telescope is a 14-inch Celestron Schmidt-Cassegrain optical tube assembly. A HyperStar optical corrector for CCD camera use at f1.9 is mounted on the telescope. This configuration accommodates a 6 megapixel CCD-Labs one-shot color camera. An Orion 80mm short tube refractor is used for image guiding.
Image acquisition and processing is accomplished on a laptop running TheSky6 Professional, CCDSoft, and Nebulosity software packages.

Isengard Telescope
The Isengard telescope is a 16-inch f/6 Newtonian style telescope made by Cave-Astrola. It is mounted on an equatorial mount. The telescope was donated by amateur astronomer Lt Col Bill Isengard UASF (Ret).
The telescope is equipped with an Astrometric Systems tracking drive that can be controlled using a laptop. Nexus DSC Pro digital setting circles are also available for moving the telescope scope manually. The focuser has a motorized Feathertouch unit so that tube vibration is minimized when refocusing. A variety of 1.25-inch and 2-inch eyepieces and filters are available for use with the telescope.

16-inch Dobsonian
The 16" Dobsonian telescope is a re-built Meade optical tube assembly on an improved mount. It is equipped with an NGC-MAX digital setting circle system. It has a finderscope and a Telrad. The base has wheels that allow easy movement of the telescope from the Main Dome building to the observing field. There is a Setup and Operations Guide for this telescope in the GNTO Files.
Specs:
406mm aperture
1830mm focal length
f/4.5
15-inch Dobsonian
The 15" Dobsonian telescope is a re-built Discover telescope. It uses the original mirror with a lighter optical tube assembly on an improved mount. It is equipped with an Argo Navis digital setting circles system. It has a finderscope and a Telrad. The base has wheels that allow easy movement of the telescope from the Main Dome building to the observing field. There is a Setup and Operations Guide for this telescope in the GNTO Files.
Specs:
381mm aperture
1905mm focal length
f/5

10-inch Dobsonian
The 10-inch Dobsonian telescope is also called the "Pellegrino Telescope" because the tube was constructed and used by George Pellegrino.

Solar Telescope
The solar telescope is a Coronado Personal Solar Telescope (PST) mounted on a tripod.

Large Binoculars
The Astro-Vue RA-88-SA binoculars are 88mm binoculars that use a pair of 1.25-inch eyepieces mounted at a right-angle for comfortable viewing. The binoculars are used with a parallelogram mount.
