I have a 10" f/5.5 mirror, does any body know if it is possible to convert it to a cassegrain type set up?

Michael,
Not likely as most cassagrains are primary of F2-f4 and then the secondary magnification multiplies that by 4 to 6 times..
Additionally, coring a finished mirror would like ruin the figure...
Sorry...if you want a Cass, sell this mirror and buy a cass...
If you are interested, I think I have a 12.5 inch Cass set somewhere around here...no idea what state it's in as I purchased it here on Astromart...and have not tested it yet...
I'm traveling starting tomorrow to Monterrey Mexico for the next 2 weeks, but if interested, drop me a note and I'll respond when I get back...
Best Regards,
Preston
