Description

Data: NGCAT (http://ngc.astrophotography.team/)

Processing: Cedric Raguenaud (http://raguenaud.space/2021/02/pk-16431-1-en-sho/)

The surface faintness of the nebula and the weather in Southern Spain made the processing challenging: it was difficult to find clear nights to take images this winter, and even with over 24 hours of integration, the SNR was quite low (especially in SII), making the post-processing a painful process to balance details and noise.
