Hi Andy,
Thanks for your comments. All my imaging is done using a ZWO ASI071-Pro OSC, although I do now have a ZWO1600MM-Cool Mono, with LRGB Filters, I picked up a few month ago from Iceinspace Trades. I haven't tried it yet. I'm balking a little on yet another learning curve, and the shear amount of space needed to store the original data, even my OSC it's around 3 to 4GB of data for one night, LRGB would be 4 times that plus. From Boronia which is not that far from your location, I found that taking lots of 5 to 6 minute Subs to be about the optimum. For galaxies, which is what I mostly do, I need to take at least 4 to 6 hours to drag them out of the light pollution. Secondly, I usually start when they are rising and hit around 35 degrees and give up when they pass over the Zenith and start to sinking into the west, where the light pollution is the worst for me.
