Hi all
I seek the optimum Coronado system for detailed solar viewing. I have a MaxScope 40, double loaded, which I like very much. The second etalon makes it possible to get a very narrow bandwidth. But I can't get it to magnify the sun the way a small refractor will, for example, magnify the moon. This leaves me in the lurch for detailed viewing of the surface of the sun.
When I take off the extra etalon, the bandwidth increases and the image gets much less compelling. So I am worried that a MaxScope 60 or 70 or even 90, single loaded, might not give me better views. Any ideas? Should I try one of these other animals, or put an etalon and Blocking filter on my lovely TV85?
