Thanks again for all the positive comments!
I took 6 darks while I was packing up at 5:00am, and definitely need a few more. I was using iso2000 and an astronomiks 2" CLS filter, (otherwise 10 mins would be way too much). The filter introduces a whole new set of problems with colour balance and background, but does seem to do a good job on the light pollution. I took a widefield with a 14mm lens in between targets, 3200iso and 30 secs, and it looks like the sun is just setting, thanks to Perth's disproportionate skyglow!
I do like the D800, but cannot bring myself to modify it with a different IR filter, so I guess I need a 6803 chipped camera in the next couple of years, now I'm addicted to full frame...
However - with the D800 in Pixinsight, using 32 bit floating point, the working files are 414Mb. The files I was uploading to astrobin are 'only' 10-20Mb, but the number of pixels was enough to force the poor guys to have to stuff some more RAM in so their server could resize the images!
cheers,
Andrew
