3 Meter (10ft) ObservaDome purchased new in 1989 for House Mountain Observatory in western Virginia. The dome is all aluminum construction with a steel base ring and is very rugged with the ability to withstand strong winds.

The dome currently houses a 130mm Astro-Physics APO refractor on an Optical Guidance System mount. It previously housed a 16in Ritchey-Chretien by Optical Guidance Systems. The dome rests on a flat-roofed wood frame building. The steel base ring has an outside diameter of 2921mm (115in) and an inside diameter of 2667mm (105in).

The dome is rotated by a ¼ horsepower 110 volt electric motor. It does not have a computer controlled rotating system, but might be converted to one.

The clear shutter opening is 965mm (38 in) in width and extends vertically from the base ring to 559mm (22 in) beyond zenith. Clear space from the radial center of dome is 1499mm (59 inches).

The original owner’s manual and assembly instructions come with it.

Buyer will be responsible for disassembly and transport to its new location.

The OGS German Equatorial telescope mount is also offered for sale if desired. Price negotiable.
