I just recieved this in partial trade for some items I recently sold. I don't have time for another project so it is up for sale. It is a coulter 8" f/7 primary and a secondary(1.52 I think), UO cell, UO secondary holder and spider, and an orion 2" focuser. It is all in exc++ to almost new condition. I have not verified the focal length of this mirror and there are no markings on it. Also, the individual I got this from still has the aluminum tube for it. If interested let me know and I will connect you with him. Here are the specs right from the coulter page
MATERIAL -- Precision annealed Soda-Lime glass
SURFACE -- 1/8 wave or better
COATING -- 89% Aluminum with SiO Overcoat
THICKNESS -- 8:1 Diameter-to-Thickness
HAND-FIGURED -- Free of objectionable astigmatism, turned edges and
other common optical defects.
New this package would cost around $335 shipped. Asking $225 shipped or would consider a trade for a nice eyepiece(radian or panoptic), a nice finder, 2" diagonal, possibly an ota or any other intersting astro item plus or minus a little cash as needed.
