Re: DSI CCD Question

I've used a DSI and DSI Pro on my Meade LXD75 SC8 and they work fine. The DSI Pro is particuarly well suited because of its high sensitivity and sharp image. The only problem I have with the specific item you link to is the price is a tad high. You should be able to find a DSI Pro for about $200 w/o filters (camera only) and $250-$300 for the camera w/ filters. Another option would be the Orion Deep Space Imager...

...which is a bit more expensive, but it has a larger chip and is available new from Orion.
One limitation of these cameras is the chip is fairly small, and you'll want an f/6.3 focal reducer to get a better field of view. Also, in these small chip sizes I'd shy away from color cameras as their images are a tad soft. However, a good Plan B would be to go with a DSLR like a Canon Rebel XT ($450-$550) or XTi (about $650). This would get you into a large format color camera that would be a great match for your 8" SCT. With my 8" scope I use my Rebel XT/XTi most of the time for general purpose deep sky and lunar imaging, but if I really want to go as deep as I can chasing small or very faint objects I use my DSI Pro.
