***MIRROR AND CELL ARE SOLD--THANKS NATHAN***
Celestron Newtonian primary mirror from a 1997+/- Starhopper. I bought the Starhopper last week as a quick mounting solution for a premium Royce figured mirror I purchased a few weeks ago.
I took this mirror out briefly once after I got it home and while I confess I didn't let the scope fully acclimate to outside temperature, I did find the star test showed similar inside and outside of focus rings, as was described to me by the seller. I also saw some good detail on Mars. Beyond that, I can't guess at a figure--it appears to be a nice mirror.
There are a couple scratches-- one is ~5/8" and is like a hairline and the other is ~3/8" and is slightly wider. They look like they are only in the coating to me. I think recoating is unnecessary and minor blemishes like these probably have no visible effect at the eyepiece.
Mirror also comes with a complete cell for a 10" ID tube--it could be easily modified to fit a slightly smaller or a larger tube.
How about $110 shipped in the CONUS, or make an offer.
