This is a homemade mount that my dad made back in 1960 to control his 6” f10 refractor. It was recently replaced with a goto mount. Various modifications were made over the years to modernize and upgrade this mount. This mount assembly sat atop a 16” diameter concrete pier and was bolted to a custom made plate steel “wedge” by a local welding shop in 1960. This steel plate weldment is fabricated of ½” plate steel and weights in excess of 100 lbs, This was fabricated to a 42 degree angle to reflect his observatory latitude in East Hartland, CT. That angle can be easily adjusted with shims to match your latitude. This base measures 13” x 15” outside dimensions. The angled portion of the base has been detached temporarily from the main base in order to move this assembly around. This base wedge is included with this mount package. The telescope shown in the first picture below is not included.

- The RA axis is 20” long, is 1.5” in diameter made of steel bar stock, has a 180 tooth 7” diameter drive gear machined by an unknown manufacturer, it is machined from aluminum or possibly stainless steel. The shaft is mounted in Boston pillow blocks, has a 6” setting circle. It has a spring-loaded adjustable clutch mechanism of unknown manufacture.
- The DEC axis is 29” long, is made of 1.25” dia. steel bar stock and is manually controlled with a knurled knob which drives a 300+ tooth brass gear which is 6” in diameter. There is a manually released/adjustable clutch. The telescope scope rings attach to the homemade plate. The scope rings are not included.
- There is a very accurate clock drive on the RA axis driven with two Hurst motors that worked well the last time I used it. There is a remotely adjustable speed control to accelerate RA movement and to adjust the speed of the motors. The manufacturer of the speed control is not known.
- There are 6 counterweights that fit the 1.25” steel axis. They weight approximately 2.2 lbs. each.

This is a very heavy assembly which is located in East Hartland, CT. Crating would be virtually impossible. Pick up on site would most likely be required. I’d be willing to drive 100 miles to meet a buyer that has interest in this mount This mount served my dad well for over 40 years. Thousands of people saw through his 6” refractor over the years at his dark-sky, high elevation observatory.

I’d be happy to try to answer any questions you may have on this classic mount.
