I have a wonderful 10" f/5 Raycraft Newtonian in a Parks fiberglass tube w/ very heavy cast aluminum mounting rings. This also includes a classic Parks 50mm finder with helical focuser (very sharp).
The primary was completed by Mr. Alan Raycraft earlier this year and the wave numbers put it at 1/13 wave - wavefront... excellent. Documentation on the mirror is included.
This was intended to be an imaging set up but i found it is just a little too big for my mount. There is plenty of backfocus for imaging. I have also considered converting it to a dob so I have altitude bearings available if someone would like to make a premium dob out of it.
I'd like to sell the entire OTA with very heavy cast aluminum rings (worth a lot of cash on their own) for $650... but will part out if I can't find someone interested in the entire OTA.
