Thanks everyone. Imaging isn't the main reason I bought the DSI but I am interested in how it performs.
Louie, this shot is a total of 35 images at 30sec exposure with autodarks. It was quite dim on screen but pulled up quite bright with some PS tweeking.
Gary and Rob. I don't know about the "blobbiness", though I was aware of the issue when I bought it. The pixel size is 9.6X7.5 if I remember correctly. Compared to the ToUcams 5.6X5.6 and the LPI's 8X8. Rob I'm already thinking of ways to cool it. It should be easy enough to build a jacket for it and drop some dry ice into it
Thanks for the offer Davo but I'll see if I can modify the 300D to autoguide for the DSI
Mike I think the DSLR would win 10 times out of ten for resolution, but the DSI would win for colour range. I'm hoping to do a comparison over the next few weeks. I'll let you know how it goes
