A new experiment

[bl_Bigdog]

I was curious if anyone out there may have an old telecope or something like that. I was talking with another group that Lana had to refered to me. They have a photographic theory that requires a concave mirror. If someone has one that they can either sell real inexpensive or even better free. Please let me know.
Thanks!!!

The experiment I am attempting is called Schlieren photography, I am trying to figure a way to make it larger and portable for investigations. It also has to be Carmon proof..lol the unit is sensitive to vibrations... If you are curious about it here is a link to a you tube video.
Again the only part I am missing is a large concave mirror. so if anyone has a mirror or an old telescope laying around I would really appreciate it.
