Out of curiosity, what do you think it would cost to get it re-ground to F/2 or F/3.5?

Would make for a serious astrograph.

Possible?
I looked into doing just that and you might want to give Mark a call from Deep Sky Optics.
As it's not an old mirror damaged or needs recoating it's a waste to regrind it.
Mark advised to sell it and he is making me an f3.8 mirror for an f3.8/2.75astrograph.
