Hi I need help in correcting a severe TUE on my 8” F/7
Mirror. ROC Difference is about 8mm. I haven’t tried anything except a
slightly longer stroke somewhere between 1/3 and ½ but these
hasn’t been much difference. Mainly staying away
from a ½ stroke in fear of a central hole. Should I use a localized
small tool or can this defect be cured by texereau’s method of a ¼ stroke
with pressure on the edge. Thanks Aditya Munshi |
