Thanks Guys, I have joined the Cloudynights forum and am currently researching some options.
The new Malincam seems to be quite a beast, but you need to fork out the bucks if you want one.
I'm not certain whether I need that level of sophistication for what I wan't to do - use the camera as a more sensitive alternative to an e.p. and to be able to see colour in nebulas without spending a fortune.
Would I be correct in assuming that the camera needs to be peltier cooled to obtain zero hot pixels, or is it a combination of new chip technology and cooling?
It's a pity that the GSTAR -EX mini colour and Mallincam jnr are around the same price more or less.This makes the choice towards the GSTAR a difficult one as the performance and specs. are quite different.
