Mark, definately an insperation for me to the point I may look at changing my order to an F3.5.
I am warming to the idea of no ladder observing.
Another site that has got my attention is
http://www.loptics.com
He is regularly doing mirrors to F3 and less with great results and with the new paracorr 2 designed for even faster scopes than F4.5's around the corner coma will be eliviated.
Got any more pics with out the light shroud so we can see the working bits
