Nice image Bo for a low exposure!
I've never found this an easy target - it has quite a low surface brightness for a PN. The smaller ones are often easier. Also Melbourne's night sky isn't very dark - hard to get a nice black background.
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.
Tony.
