I find I can get really good looking dslr images of the brightest targets with an hour of exposures, but helix or tarantula images end up looking very noisy.
I guess one way is to lower the ISO to 800 or even 400 I agree re dimmer images and increased noise.

Thanks Dunk, but the clouds are having a permanent holidays here in Melbourne.
