Description

First light with my FSQ85 with reducer and the Atik 383L+, I do love the pixel scale and FOV.

Data collected over many nights through December and I've also been using new PI techniques (multi-scale techniques) to help reveal the faint halo. I'm not yet sure it's the final version and may return and re-process.

Revision B: reduced saturation.
Revision C: lightened and re-boosted saturation - I do like the blue!
Revision D: more natural colour tone and processing
Revision E: blended in my daughter's data from her recent capture in 2015

Thanks for looking.

Barry
