I have a Nova 12.5" mirror made in 2004. It is F4.5, 1.5" thick and has never been out of the box. It looks like a great mirror and it is marked by the maker at the optical center. I'm also willing to throw most of the parts to build a Plettstone type scope in for free. That includes the secondary mirror, upper ring, tubes, mirror box, unfinished tube clamps, mirror cell triangle, and the half moon shaped rings for the bearings. I do not have the rocker box, focuser holder or focuser, diagonal holder, or the little right angle pieces that hold the diagonal in place. BUT i can give you copies of the drawings to make these things?
I can sell and ship the mirror separately, but for the other stuff, I'd prefer you come pick it up. Feb 2015 still available
