PicturavisCat's Paw Nebula
This is my attempt at the James Webb Space Telescope data of the Cat's Paw Nebula NGC 6334. Many stars were removed or oversaturated in the filter data downloaded from MAST, resulting in a lot of artifacts in the short- and long-wavelength composite images created with #Siril. I combined both images in #GIMP and tried to fix some of the artifacts. After different tries, also on the raw data, I decided to run #StarNet++ on the combined FITS file created with GIMP and then painstakingly clean the rest (felt like 10000) of the star artifacts up. I tried to stay true to the nebula by interpolating what the area behind and around the stars most likely looks like. GIMP's heal brush worked really well, but it took many hours to complete.
The full-resolution image can be seen on my website when choosing the original size in the upper right corner (warning: it is 77 MB in size): https://www.picturavis.com/picture?/391/categories
Telescope: JWST/NIRCam
Proposal ID: 6778
Observation description: NIRCam observations of a star forming nebula
Release date: 10.07.2025
Filters: F090W (blue), F187N (light blue), F200W (blue-green), F277W (yellow-green), F335M (yellow), F444W-F470N (red)
