NGC 6357 RGBSHO

NGC 6357, also know as the Lobster Nebula, lies at a distance of 6,500 Light-years from Earth in the constellation Scorpius. There are numerous massive stars lying within this extremely large emission nebula, notably the cluster Pismis 24 located within the large blueish hole near the center, has some of the most massive stars known in our galaxy, many of them being over 100 times the mass of our Sun. The central region of the nebula has numerous pillars of dusty molecular gas which probably hide massive protostars. The intricate shapes of the gases within the nebula are carved out by the stellar winds and huge amounts of radiation from the young and massive stars that we can see and from those embedded in the gas clouds.

This image was a REAL pain to process! I finally decided on the traditional Hubble Palette and then using ColorMask and curves to try to get the colors to be pleasing (trying to get the Blue to show up in the central regions was a REAL challenge) and then processing a separate RGB image to allow me to substitute RGB stars for NB stars. I'm still not completely satisfied, so I'll keep trying to make this better.

Anyway, hope ya like it!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
