Hi from Neil
Just touching base. I have returned home after 2 1/2 months in the US. National Parks road trip and stay with family in NY.
Glad to hear you may have found an alternate observation site.
I expect to return to my mirror grinding project soon.
I purchased a slightly damaged 8" mirror and have been re-grinding it.
Started with #220 grit (Silicon Carbide) to remove the existing alloy coating and reduce it to Focal Ratio 4.5 from a 6.7.
Progressed to #320 grit to make my target of 2.83 mm sagitta.
Had to leave the project at this stage for the US.
I suspect I may have to re-asses the quality of my plaster/tiles grinding tool to achieve full contact and an even sphere from centre to edge of the mirror.
All the best
Neil
