Description

Shot this over a 4 night clear patch in mid-September in the UK. This ended up being a challenging series of captures - two nights were disrupted by a windows update on my mini PC, while seeing was variable.

This is a 4-pane Ha/OIII/SII mosaic - the Sadr region always looked so dramatic to me and I wanted to capture it, but I thought it would be a shame not to capture the Crescent nebula nearby, so I went for the mosaic!

Processing was also challenging given the different quality of the 4 panes, which is why I'm posting this a month after shooting.

The colour mix I went with was my usual natural blend mix:

R = 0.76*Ha + 0.24*SII

G = OIII

B = 0.85*OIII + 0.15*Ha

Captured in APT, pre-processed and mosaic merger in APP, post-processing in Pixinsight.

Thank you for looking!
