how can i mount a secondary hyperbolic lens to my correcting lens in a schmidt-cass i'm working on?i plan on drilling a hole in the corrector to eliminate spyder defraction. any ideas??

I think it would be better to clarify the question a bit. If it is an SCT then it has a corrector which holds the secondary. Therefore, there is no spider diffraction because the secondary is held up by glass. Since there is a hole in the corrector to hold the secondary already, it isn't clear why you are drilling one. So it's hard to figure out what you're doing.
Modifying an SCT is a very technical question for Yahoo! answers and it seems to me that you would have better luck on one of the Astromart forums. Or, read the wiki article below and check out the links that it provides at the bottom.
Good luck! GN

Hi. A Schmidt-cassegrain already has a hole in the corrector plate. Do you mean a Schmidt-Newtonian? That is what I have and it also has a hole in the corrector plate. Drilling into a solid corretor would cause deformation of the aspherical figure, so make sure that is what you want to do. Good luck!
