Well, maybe it is time for a sixth new mirror?
I just received my 8" f4.5 cave
Here is the info inscribed on the side of the mirror
Cave Optical Co.
-F/4.5 - 36 1/16 f.l.
Dec - 19 - 1973
I hope to be able to get first light on it today, but I may have some other issues to bug out of this scope before I get to it.............
Just an update on my mirror. I sent it to swayze Optical. He found it was petty badly over-corrected. It has been reworked and is in rout to Spectrum Coatings for its new coatings. Steve says "it turned out fabulous" I would imagine it will be several more weeks(at least) before I get it back.
I'll update more when I do get it back.
