Thor's Helmet (NGC 2359)

Taken from Shepard State Park in Gautier, MS and my neighbor Calvin's front yard in Mobile, AL. I sincerely appreciate him allowing me to use his yard for astrophotography.

This image is made up of 292 three-minute sub exposures for a total of 14+hrs over four nights using an Askar D2 Ha/Oiii filter.

"Thor’s Helmet is an emission nebula with an ionized HII region in the constellation Canis Major. The name of this nebula stems from its striking resemblance to the helmet of the famed Norse God of thunder and lightning.

Thor’s Helmet is composed of cosmic dust and gas, which is revealed to have a blue-green appearance through astrophotography. NGC 2359 spans roughly 30 light-years across and appears as an interstellar bubble that has been inflated by a central Wolf-Rayet star." - AstroBackyard

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.
