While I was in Sydney I purchased an A4 sheet of Baader AstroSolar Film. I was thinking about making a filter for either the WO66mm or the Orion 80mm scopes, not sure which one yet.
What I would like to know is with either scope is it necessary to make the filter area as large as the aperature or would I be able to use a smaller diameter solar film than the aperature of either scope, obviously I need to make sure that no light from the sun enters the scope except through the filter.
I dont want to waste the Film making something bigger than necessary.
Anyone use either of these scopes to view the sun? What are your thoughts?
