NGC 2359 Thor's Helmet and Surrounding Clouds

NGC 2359, Thor's Helmet, is an emission nebula apparently produced by a super-massive Wolf-Rayet star interacting with a molecular cloud, which would explain its unusual shape (Wikipedia). It lies about 12,000 light years away. Its core star is thought to be on the verge of a supernova.

Processed in PixInsight using R-C Astro's tools. Stars and target were separated while linear, processed separately and then recombined with Blanshan and Cranfield's Unscreen Stars script. I used Local Histogram Equalization and GAME masks to enhance contrast in the brighter parts of the nebula, and a series of Range Masks to keep those bright parts from getting too bright.

I did not rotate the image "horns up" so that the nebula could be appreciated in its own right, without imagining it on Chris Hemsworth's head.

The refractors!

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.
