Hi Gary that looks pretty close to me go ahead and do the coudermask test. If you are really close then the measurements on the couder mask should confirm this. Take about 5 measurements of each zone and average them out. When you have the results you have to plot them in a graph and see what you come up with. Also do the focault test measuring the images from inside to outside the field of curvature (.707 I think) and if the measurements add up good(See texereaux). Once all this is done and everything measures up you are done. Once you take the measurements let me know and I'll run them on a program I have called figure 45. I don't know if it is still available but that plots the graph snd gives you the wave measurement of your mirror as well.
Regards Cristian
