With a TV101 or TV102 and a Coronado solar Max90mm, what is the best scope & blocking filter arrangement for solar observation?
Thanks, Rob C

Robert, I use a 60mm Solarmax with BF10 blocking filter and adapter on a TV np 101 and TV 76. Some people have recommended the larger BF30 straight through blocking filter for the 90mm, but if you're used to using a 90 diagonal either the BF10 or BF15 are rated for a fast scope like the TV 101/102. Either scope should provide essentially identical prerformance. There are a couple of Coronado and solar viewer forums, here and on Tahoo, that cover the debate in more detail.
