Cutting back on my projects ........... too busy being a grandfather :)
So I am selling this Orion Optics U.K. 10" F4.8 (248mm /1187mm) Research Grade Primary Mirror and 63mm secondary with OOUK 4 vane spider.
The substrate is Schott Suprax and it is 25mm thick so it cools very quickly. The mirror is four years old.
There is a fine scratch on the mirror. and fine marks but it is still in good condition (see pic), both mirrors are centre spotted.
Just no time for building scopes at the moment. :(
