Hi,
Is there someone out there who can help me obtain the optimal collimation bolt pitch circle diameter for my 10" f/5 mirror? I would like to use 3 point support. I am also considering using a 4mm aluminium backing plate to keep the thermoelectric cooling option open for the future... Using the Plop program looks a bit tricky....
Some basic info:
Material = BK7 glass
Outside Diameter = 250mm
Thickness = 34.5 mm at outside edge
I'm not sure what other info is required?
Regards,
Andrew.
