VD,

Thanks for the info. I know about the extreme sensitivity to
collimation of a true RC and the precision needed to execute it
successfully. I personally never had confidence in Meade's ability to
get that level of precision at such a low price. If the mirrors aren't
hyperboloids, then how can they get away with calling it a R-C? It
seems like it would be easier to use a subdiameter corrector near the
focus to improve the optics rather than a large front corrector.
