From 1982 by the marking on the mirror. Primary was figured to 1/8 wave, secondary flat to 1/8 wave according to the Edmund catalog. Everything on this telescope is built heavy. Red phenolic tube. Heavy cast aluminum end rings, cast aluminum fork mount, cradle, and tripod legs. Finder tube and objective is from a similar Edmund telescope but with newer diagonal and eyepiece. Original offset spider with original 2 5/8 inch diagonal. Oversize 2” focuser with large backfocus for astrophotography. Original Edmund clock drive and manual slow motion control on the declination. See ad #191051 for the Edmund catalog page describing this telescope.

Overall condition is very good. Optics have just been re-coated by Clausing. Telescope works fine and gives nice views, but there is some backlash in the clock drive. If I were keeping it, I’d do some work on the drive before doing astrophotography (I think the motor shaft has eccentricity causing the backlash – gears look good). Has a few scratches and scuffs on the tube, but still looks good. Original thumb screws (except for a couple) are a little rusty but work fine.

I’ll include a 2” extension tube required for using 2” eyepieces (has original 2” to 1.25” screw-in extension – I believe these threads are for a T-mount adapter) and a 28mm RKE eyepiece. Also Includes an Edmund off-axis guider made for this telescope model. (These are very hard to find.) It’s a combination of cast aluminum and brass which sold for $250 back in 1978. This was never mounted on this telescope, but would be easy to mount. Also have some extra 1/15 rpm motors I’ll include for parts.

Email me for more and higher resolution pictures. The picture of the gear was taken with the cover removed – the telescope is complete and includes the cover.
