“Vibrant, nice colours/saturation and clean background,” noted one of the judges.

Girones said she used the Level 3 data package and edited the image using PixInsight.

She said she used Weighted Batch PreProcessing (WBPP) script for calibration only of luminance, red green and blue, with cosmetic correction — “many hot pixels!” she noted.

In building the image, she used tools like deconvolution, dynamic background extraction, MultiscaleLinearTransform (MLT), TGVDenoise and a variety of other features.

“What a wonderful galaxy!” Girones wrote.
