Hi, my first mirror has turned out to 1/18.9 at zone 3 according to tex.exe but under a ronchi test OUTSIDE of focus, the edges turn out at the very top. Is this what i think it means that I have a TURNED UP edge. I dont want to get it wrong and apply the wrong action and screw up what is now a very fine figure.

Thanks Please send message to brummund@islandnet.com
