I like the tilted newt design. Does the folded cost you any contrast. I know from the basic newt that the secondary blocks light, what effect does the 2nd secondary have since it is blocking part of the light cone after it is reflected from the primary. Two spiders? I have only seen one telescope on the internet that uses anything that strays from the basic disign. Does anyone know a web site that has more details on folded and tilted secondaries?
