Thanks Guys,
Jase I've seen those Lazarroti? optics on the web before and have been intrigued - I wonder if anyone has used them on the forum. They look ideal from pov of F ratio and cool-down properties... dew might be a problem though!
Anthony, I certainly agree on all the factors you list needed for top planetary photography. I have them all from Lymax coolers to Hutech mirror locks and zero shift moto focusser, the DMK industrial grade firewire mono cam and motorised filter wheel and take great care with collimation etc using bob's knobs etc, the latest processing software etc. I can always use more practice on technique of course and am constantly learning tips from the guys here and the getting the best seeing is all about putting in the time to score those sweet moments. With these in hand though it must be said that aperture (optical quality being equal, and that's perhaps debatable between C9.25 and C11) should deliver finer detail due to improved resolution capability... when the seeing conditions allow. Guess I'm seeking a little leg-up for that bity of extra motivation
cheers,
