Thanks John!
I don't have a filter... just the straight camera and adapter. This is my first tentative step into imaging after many years of observing. I figure if I can get some experience using a simple camera and processing images, I can take the step of getting a "real" camera when next year's tax return comes back...
On the plus side, a C9.25 on a CGEM is a great scope/mount combination... so any errors are 99% my fault if the images don't turn out!!
