Thanks David. Your experience suggests I will not have a problem with an uncooled camera in the much cooler nights down here.

Iíve never had a noise problem so significant that I couldnít see some good detail on the screen within 10min.

I do a bit of post processing on my phone with photoshop express which allows me to pull some further detail from even the feint stuff. But in doing this I start to wrestle with the noise issue which I think can only be properly resolved by going to longer integration times (and for this you need a cooled camera).

For what youíre doing- go for a uncooled.
