Query: Works on Linux, but not in Windows 7.

I bought it on eBay long time ago.When I used it with my old laptop with Windows Vista 32:The camera worked, but since it is like an eyepice of 5mm it used to be very hard to keep the the image in the center of field. Maybe because I have no motor drive. The image was a disgrace, the RegisTax version old, and AMcap is a very bad program.Now with Windows 7 64 bits: There is no drive from celestron. Their web site tells us to get the phillips drive for SPC 900NC. But with it the AMcap no longer works. Other programs are working, but in 176x144 and not anymore in VGA.Now I will try any webcam with an adapter I just bought. Do yoursef a favor. Don't buy this. Try something else.Update: Ok. It is working now. but not in windows 7. It works in ubuntu Linux. Just get the movie with "cheese", save it as .ogv and then use "devede" to converte to avi.
