Hello again, It is very much appreciated that you shall help me through this Cristian, shall save me a few hours work! and mistakes....
Here is my efforts last night. I did 1/3 coc MOT for 20 mins. Done a test after 30min cool down. Lines in ronchi test looked good as well as the knife edge with the hill in the middle much smaller as well. Repressed for 15min then done some 3/4 w MOT putting some more pressure on the edge to reduce the centre hill, done this for about 15 min. I don`t know that I have done the right thing here? but heres the picture of it. Still a small hill and a bit uneven, still think there is a slight TDE? It is hard for me to tell if this is diffraction or a real feature.? .......
Thanks Gary
