Corona Australis - now with MORE DATA

A good run of clear weather has meant that I've really been able to crank out the images over the last few weeks. Leaving the scope set up in the backyard (protected during the day by ye olde camp shower tent) as well the extra features of my new rig have really helped reduce the wasted time seting everything up before an imaging run. This must be what it's like to have a permanent obs

Anyway, this is my first attempt at this target. Lots of faint dust is pushing the uncooled DSLR to the noise limit. Perhaps I've pushed it too far (??) and so an additional night of imaging it may required to bring the noise under control whilst still retaining extended detail. Any advice here would be appreciated Have been trialling ISO400 for my last few image runs as well, and am finding a lot more star colour is being recorded, but maybe this has been at the expense of noise in the extended regions of the image?

Details: 43 x 5min dithered subs, collected over two nights. Processed in Pixinsight. Hi res version here: http://www.astrobin.com/full/39410/B/?

Comments welcome I am really feeling like the quality of my images has improved a lot recently, and a big part of that is having lots of quality images from the experts amongst us here on IIS to emulate and strive towards.
