I would like to make a telescope and I found a mirror about 7" from an old piece of medical equipment. I brought it to an astronomy shop and they told me that they had both good and bad news. They said that it it a good mirror, of good optical quality, however they said that it was spherical and not concave. It sure looked concave to me, so I am not sure what they were talking about. They told me that I could build a telescope with this mirror, but I would have to drill a hole in the middle. I would like some advice and enlightenment into what would be the best route to go with this mirror.

Please reply if you have any information.

Thanks in advance.

I just wanted to note that it is unfortunate that people have to post garbage mail (OLGA CRAP). I guess some never grow up and/or learn what is and is not appropriate!
