76mm copyscope OTA

I have a homemade 76mm f/5 copyscope made from a Fujinon copier lens. Len appears fully coated (possibly multicoated) and is good for wide field use under dark skies. The optical tube assembly comes with a brand new GSO mirror star diagonal 1.25" (itself worth $50 new plus postage!). This copyscope is unique as it does not use a drainpipe pull and push focuser rather it comes with an Edmund Scientific rack and pinion focuser. I can include a large hose clamp and a homemade mounting plate (see piccy).

The OTA itself with the R&P focuser fully retracted is approximately 12" long and weights about 1.5kg. I was looking at getting about $65 for this and preferebly via pickup (postage would cost at least $15 by regular mail). Does not come with eyepieces but if you want I can include the Orion 20mm Expanse (66 degree FOV) for an extra $40.

This will make a good grab and go scope on a photo tripod or a large finder for a big dob and you can be sure the quality is going to be better than those plastic e b** 80mm f/5 scopes. Prices are negotiable so do let me know if you are interested and we can work something out.

Cheers,
Darren
