Sorry Jonathan, I wasn't meaning to worry you. I have nothing definite to go on, but of all the Celestron SCTs, the 11" is the one people most commonly moan about. There seems to be a widely held view, that it is not up to the standard of either their larger or smaller SCTs in their range. Common moans seem to be lower optical accuracy, disproportionately large central obstruction, it is sometimes accused of sub standard build quality while the other sizes are praised. It's the one Celectron SCT that the Celestron fans don't seem happy with (I wouldn't waste time crediting complaints by people trying to laud Meade or something). This may all be rubbish, or it may be a quality control problem that's since been delt with, I just don't know, but when a concientious ametures offload their 11s and go back to 9.25s, I'm not personally inclined to doubt them enough to make a trial of the thing myself. Obviously your commited to the 11, and I'd be interested to hear your opinion of it compared to other SCTs you've used or owned.
Thanks for the Argo Navis tip Paul, I'd heard of it but never bothered looking it up. Definitely worth some thought.
Does anybody have any thoughts or opinions on the Celestron equatorial mounts and goto units? Seem more expensive than Losmandy, which surprised me.
Does anybody have any thoughts, opinions or experience with the Vixen SCTs. So far as I know they don't make bigger than an 8", and their optical system isn't pure SCT (something different about it) but I don't know more than that, and that their refractors have a reasonable reputation.
