Schlieren 18" Mirror Test

http://www.ian.org/Schlieren/

What luck, I managed to find an 18" primary telescope mirror, so I set it up to do some more experiements.

Schlieren photography makes air curents visible. In this video I light a butane lighter and hold my hand over it. At the beginning you can see the butane gas coming out before the spark ignites it. At the end I blow it out.

This is my first attempt.. I really need to build some proper hardware for adjusting things, right now it's all boxes and booklets and tape and gets out of whack if I sneeze, let alone if one of my cats rubs against it.

Never knew you could do this kind of thing with telescope mirrors. I have a 6'' mirror from a junk telescope which would otherwise be useless, maybe I could try it myself.

I know someone with a 20'' telescope, but I don't think they'd let me o.o.
