This was one of the first deep sky images I had a go at a couple of years ago when I didn't have a guide scope and even less of a clue than I have now. So I thought I would give it another go.
20 x 240 seconds at 800iso. Could have done more, the sky was clear as a bell. But it was a school night.
10 x Darks. The first one was a mass of red because the sensor was sitting at 46C so I had to wait a while!
20 x Bias
20 x Flats at 1/25 second on Av. The histogram looked high but they turned out ok.

Not sure what happened in the over processed centre but quite pleased with the colours.
