Until you have used a scope with baffles and have installed them in a scope, baffles can be baffling. :) http://www.atmpage.com/baffle.html is a place which does a good job of explaining how to design baffles for your scope. The flocking paper that you have installed does a bit of the same type of job by tending to intercept the incoming light and reflecting it back out. Unfortunatly, there are a lot of edges in the paper and the light is refracted/difracted from these edges so you don't get the full effect of what is possible. I'll bet that you have found that the sky is darker witht the flocking paper in place? If so (and I know you have), you'll see even more of the effect when you put in baffles. As the article says, the baffles can be made from a lot of different things. The important thing is to make the edges at an angle and as sharp as you can easily make them. When you're done, you'll have a reflector that's as good as a refractor of the same size and not have the color problems of the refractor.
