Description

* Image acquisition: Greg Turgeon.

* Image processing: Ruben Barbosa

* APOD GrAG (25.04.2021).

Here's my processing on data provided by Greg Turgeon for a contest (the prize will be a free 4-month subscription to the 17 "Planewave CDK telescope, installed in Chile).

The biggest difficulty in processing was to highlight the dusty areas, without damaging the image with excess brightness of the stars.

The narrowband data is very high quality and I was satisfied with the result achieved.

Processing time: 4 hours (with free software).
