I like the red one on Astrobin too.

Thanks Lee
Prior to this the most I'd tested had been 300s at 0.4"/pixel and been happy with that so I figured I'd give it a go. It gets a little sketchy with tracking accuracy past meridian so it's fine as long as it doesn't go past it.
I've also attached the red version which colour wise is my favourite but there really isn't much in the way of OIII contribution which is a LOT stronger behind the dusty regions.

Thanks Greg, I was a little worried at first given that the stars aren't as small as I was hoping for (I shouldn't have been surprised really). At 900s the star burst is HUGE but it calibrates out very well. This was taken at the lowest gain (highest dynamic range) but even then it's only got 2e- read noise!
