NGC 6357 The Lobster Nebula

After 3 months of constant cloud cover / rain in Melbourne Australia, I finally managed to gather enough data to process this wonderful celestial object.

This is an SHO image with RGB stars. This is a crop of the wide filed image I took with my 430mm refractor as I found it more interesting to look at it this way.
There are some wonderfull details in the middle of this nebula with what looks like a Koala reaching out for a star. Everyone I showed this image to seems to find a different animal in there... snakes, crabs, lobster of course!

This nebula is on the faint side with Ha and Sii being the predominant emission and Oiii being highly concentrated in the middle of the nebula, shown by the blue hue in this image.

NGC 6357, The lobster Nebula also know as War and Peace Nebula[b], [/b]is a diffuse nebula located in the constellation of Scorpius. It includes an open cluster Pismis 24[b] [/b]made out of massive stars, the biggest one approaching 300 solar masses!

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.
