Tony,
if you decide to come up we can have a look through my 8" meade and then pop up to the Mapleton Observatory (about 10 min away from me) and have a look through the C11 celestron 11". That might be useful, to you.
To be quite honest I IMHO I feel I get as good (if not better, (for those celestron users
)) a quality of image (clarity) with the meade UHTC on the lenses as through the C11, but I've not put them side by side. Though apparently Celestron have a new coating for their lenses now but I don't know much about it.
