thanks for everyone's post on this forum - I jump in and out of telescope making as time and weather permit - with lots of bad weather I'm thinking more about building.
Has anyone had experience with looking glass astronomical products - I enjoyed the discussion on sandwich mirrors - and was looking into buying a large blank 25"+ - during these cloudy / snowy days it seems like a reasonable alternative.
