I have a potential buyer but his email is bouncing. Chuck W. please update your astromart email or send me a different email. Other interested people: will hold your name if this falls through. Thanks! Greg

Selling TWO (will not separate at this price) f/10 4.25" mirrors.

Mirror #1. From Discovery and is a spherical mirror. About one year old. These are about $90 new.

Mirror #2. An old Optical Craftsman mirror that was refinished by an amateur mirror maker in the 1980s. It has a NEW beral coating from Clausing. (Coating a mirror this size is $30.)

I am not able to tell you how well these mirrors star test. As you may know, mirror focal lengths are nominal, not exact. These two mirrors would not come to focus in the tube I wanted to use them in--probably because they ARE in fact REAL f/10s (I suspect my tube was fitted with an f/10.5 or f/11 in earlier decades).

Anyhow at this price you can afford to play with these mirrors and keep the one you like and sell the other one. There is much to be learned from building a small scope.

M.O. or check from well-rated astromart user. Price includes USPS CONUSA.

thanks for looking
