Hi Cristian,
Have been doing some more polishing, but the mirror appears to be returning to a figure similar to that in my post on 24/1. Have been considering doing a short stint with tool on top to see if I can get it to move to a more spherical figure. At present I don't have an image available. Will try to get one tonight. My tester is pretty much a standard Focault/Ronchi carriage with a green led for a light source. Am still unable to get more than about 3 lines outside ROC. The width of the slit image appears to be quite narrow past ROC.
Regards,
David.
