Traditional CCD imagers are also operate well cooled while video cameras do not, and the cooling will greatly help long-exposure imaging.




This is not true for all the video products, the Mallincams (and one model of the Stellacam III) have a built in TEC cooler. The MC cooler works very well but it doesn't take the sensor down to quite the same levels as those in many CCD cameras. It's fun to watch as you turn on the TEC and see the individual hot pixels drop out one by one as the cooling takes effect in real time.

I really agree with the comments from both BrandonF and Dave (Happy Birthday by the way) about the differences and experiences. I had fun working with a DSI Pro and learned a lot but my "fun quotient" has gone way up with a Mallincam.

Like Dave I can see a dedicated CCD imager in my future and when I do go down that path it will be with a better foundation of knowledge and experience (the DSI has been relegated to duty as an autoguider). In the mean time I'm having a blast with my Mallincam.
