Hi,
Thanks for all your input. It seems like I have stirred up a quite a hornet's nest though, but all your opinions are of interest.
I have considered a range of cameras from the simple low-lux security cameras and those suggested here. In view of it all, and considering my current telescope and aspirations, I think I'm heading toward a DSI II mono. (I would prefer the DSI III with the larger CCD, but its outside my price range.) I like the 1/2" Sony EXview HAD CCD and the 16bit A/D conversion as a camera basis. The camera itself is light and compact and yet equipped with a decent heat exchanger. It also features on board frame integration, temperature sensing and compensation etc. I prefer it to the GStar because of the better A/D resolution and its compact size - better for my mount when viewing high objects.
On all counts I think this has been a very profitable discussion, possibly not only for me.
Many thanks to all who contributed.
Robert
