Thanks Mike, I love trying to get these really faint beauties, but recently i only have had limited times, with work taking a large chunk of time including many nights. But slowly im getting more time available to start doing some really deep imaging. But i would use SXV-H9 for that for obvious reasons.
The 14" RCX400 is a nice piece of equipment. If anything, the forks need to be more solid to remove vibrations. Luckly i have a 4.5 meter dome its in, so no air movements to woble it. But Optics are really magic. I really cant fault them. Even with the large APS CCD its star dots to the edge, no distortions. Then theres visual, pinpoints, no blobs or streaks. Like a high quality refractor. Plus the many ports and functions, im trying to get the cuppuccino option fitted !.

If i was to get another scope, it would be a fast CDK (Corrected Dall Kirkam) as this is the ultimate telescope PERIOD !, but for the money, i would get another RCX without a second thought. Its just that good, when they are working !.

Roger, the QE is extremely good, and in fact very high. The Kodak KAI-11000M
has a QE of 50% and thats a mono chip.
You will not find many CCD sensors with such large QE's unless you start forking out big bucks, and most likely mono to boot. Even the SXV-H9 has 65% QE. Sony are well known for producing low noise sensors. I have yet to do any dark frames on ANY of my images for both the SXV or the QHY8, thats how low they are.
Lastly i dont use any guider, just short 1 minute or less subs then stack them. Yet i have a guide scope im not using. Lazy eh!

Theo.
