That ASI camera is really performing well for you

The low read noise of 1.2e @30db gain is making a difference.
You also had superb guiding & a low FWHM.

Thanks very much Allan, I'm pretty pleased with the resolution given a 5" scope in Australian skies :-)

Thanks Rick :-) Funny you should say that, I just had it open in Photoshop and was thinking it looked a little too cyan. I think pink stars is due to some bloating in the blue channel and me being too lazy to reduce the stars to compensate.

I'm thinking I may actually get a bunch more data (skies/weather permitting), perhaps switching back to more traditional exposure lengths, at which point I'll reprocess and probably tweak the colour some.

If I had an infinite amount of spare time I'd like to write some software that minimizes the overhead for this kind of capture, but right now it's pretty nuts to try and go deep whilst throwing away ~40% of your imaging time.
