I'm wondering if anyone here has had a mirror they thought might need refigureing and gone through the process of spending lots of money only to see that there was no real difference. I wonder this because I have heard reports where people have said that after having a mirror tested it would be beneficial they were told to have it redone then the owner reports no discernable difference afterwards. Thanks

I am sure your question has been answered, but I love hearing myself talk, so here it goes. I would answer these quesions to get your answer.
1) Before the mirror was refigured did you have reason to believe there was a problem?
2) Were you getting "soft" images of Jupiter?
3) Are you new at this?
4) Did you have a chance to compare the views in your scope to a comparable scope next to you? Were your views inferior?
5) Do you know how to collimate the scope? Are you sure?
6) Did the mirror refigurer provide any data on the problems with the mirror before the work was done?
7) Did you get any verifiable results on the surface when the mirror was sent back to you?
8) Are you able to distinguish between a crappy mirror, and crappy seeing?
9) Are you still getting, or ever had soft planetary images?
10) Is this some sort of home built set up? Is the focuser set square with the tube? Is the tube straight, and the secondary in the middle of the tube, yada yada yada?
11) Do you bring a hot mirror out into the cool night air?
12) Can you visually tell the difference between a good optic and a poor optic?
If you can answer these questions then we may be able to narrow it down a little.
Good luck,
Richard
