Folded Refractor Light Loss ???Posted By William McHale |
Well if you design the scope right, the light loss will only be maybe 10% more than you loose on a normal refractor since the latter is usually used with a star diagonal. I wouldn't fold the scope so that the light returned to the back of the scope; makes it more difficult to mount and baffel. I would set it up so that the light was reflected back up through the top of the tube then you could mount it on a Dob mount . With a little thought, you can probably get the 6" f/15 down to no more than the length of a 6" f/6
