Do you have photoshop? You can use layers and masks to reduce noise a lot - if you like I can post an example. It really gets rid of the grainy look.
Faint objects are always noisier - I guess there is less signal so the noise shows up more?
I don't have much luck with faint galaxies - they need long exposures and with Melbourne's current weather there isn't much time available.

Thanks Tony,
I use Images Plus for stacking and the first tweaking and then export the file as a TIFF to PS for additional works in levels, curves, sharpening and de-noising.
If you have any links for online tutes, please post them up. I am always on the look out for new tips and hints!
