Thats an interesting read and pretty much correlates with what I heard from an academic earlier this year.

Looks like current darks are important and for aesthetic purposes a median smooth may help some of the noise that doesn’t respond to sigma clipping – on account of not being from a Normal distribution.

It does make the QHY600 a very attractive prospect.

Nice to see CMOS has finally (nearly) caught up with CCDs. I first remember hearing of them from a friend in the mid 90s – the noise characteristics then were hideous.

Of course a 123MB image is a little worrying. I might need a 2TB drive a bit sharpish, if I bought one of those.
