Several authors here have that knowledge, but you have to say a
lot more about the use of the telescope. Photographic use,
visual, or both?. What field size?. Do you need to use it in the
IR or UV? Do you really need 10" F/9 when you may get better
performance from an 8" of the same focal length?. Could you use
glass types different that those you quoted?
Please tell us more. We don't know if you are photographing
nebulae or observing Neptune. Also, look at this web page hosted
on the ATM List server for a good read :
