Helix nebula with an RC8 and a QHY8. 20 min subs x 22 (shot over a couple of sessions). Full size available on
Astrobin.
I found it hard, even with over 7 hours of data, to get much of the outer shells without over pushing the processing and getting a lot of noise. Though using a one-shot colour camera in the suburbs probably doesn't help!
Still, I was happy to get a bit more detail in the inner bits (forgive the technical term!) than I've managed previously when using less data.
Thanks for looking.
