Thanks for the freeware post Ken, one project I have been assembling is an 203mm f20 classical cassegrain. Picked up the optics fairly cheaply from the USA a few years ago when the $s' were at near parity.
Although I have Texereaus' book and used it for the calculations, it will be great to be able to compare my results with those achieved in the freeware.
Just hope the scope gives good planetary views when the secondary distance is sorted and the optics collimated and the damned rain goes away.
