Re: [ATM] Advice on Solar scopes/observation

The use of a filter glass for the secondary with the secondary
being a full aperture surface makes a lot of sense for a solar
scope.  You get an unobstructed light path as a bonus.  You also
want to build a relatively long focal length scope as you want
power without having to go to very short FL EPs.
