Does anybody remember the name of the company that made research quality cass scopes that used the same config that ealing used for their mounts, ie asymetric single arm fork? Western Kentucky Univ has one of their 24". They had some ads in S & T in the 60's and 70's. Thanks, Craig.

Some Boller & Chivens mounts had the offset counter weight.

I found an image of the telescope at WKU, definitely *not* Boller & Chivens, so I would guess Group 128. I recall that they did advertise in Sky & Telescope.

 

That type of mount is technically called a torque-tube mount.

The 7th picture posted for the auction confirms it was manufactured by Group 128.

The page where I found the picture was an announcement that they got an NSF grant to replace it with a modern 28" scope.

 

The price is right - current high bid is $110. Problem is the only way to remove it is by crane through the dome slit, and it weighs 1/2 ton.

 

Gotta think about this - could it replace my C80ED as a grab-and-go? yay.gif

AAI in Cranford NJ has one of those and it is a fabulous scope from what my distant memory recalls.  That’d be worth some effort…

I believe the late Phil Lichtman was a founder of Competition Associates which became Group 128, named after Route 128, the original 1950's ring road around Boston. It was famous as one of the first high tech areas, with many tech companies like Raytheon, Polaroid, Digital, Data General, Analogic, Teradyne, High Voltage Engineering, Itek, Prime Computer, Wang Labs and on and on located along it. After Interstate Route 95's original plan to run right through the heart of Cambridge and Boston was nixed, route 128 was renamed 95. Obviously a lot has changed, with most of the companies merging or disappearing since then.

 

I met Phil a few times over the years as we had a mutual friend. He was an interesting and clever guy with strong opinions. Years ago (1970's?) I went to the Group 128 liquidation auction, a source of some measuring equipment I have still. There was a 16-inch scope that was nearly complete that some friends bought, but I'm not sure where it wound up or is now. The telescope designs were sold to and marketed by Ealing from a location nearby, which is why there are so many similarities between Competition Associates, Group 128, Ealing and Ealing-Beck telescopes.

I seem to recall an advertisement in S&T for an 8" Cassegrain by Group 128. It was marketed towards serious amateur astronomers and small colleges. It looked like a scaled down version of their larger scopes. 

 

Please correct me if I'm wrong.

I don’t recall a Group 128 8” Cass but Tinsley had a really sweet looking one.

I'm probably confusing the Tinsley with the Ealing, thanks for the correction.
