Excellent news. Good to hear the mirror performs. Always a chance of some problem.

Any idea what to do if the the glass tool sticks to the mirror on 600 grit?

the scratches might be making a little scattered light across the field, but overall I am very happy with the performance. No deep sky tonight as scudding clouds had me rapidly switching between jupiter, saturn the moon, alpacrucis as holes in the clouds presented themselves.
