Thor’s Helmet! ⚡️

This beautiful emission nebula in Canis Major has the iconic shape of Thor’s Helmet. This was my very first target back when I upgraded from a DSLR to a monochrome camera. The result back then was pretty bad as I had no idea what I was doing. 2 years later, I finally revisited this object and am very satisfied with it despite the low exposure time (10 hours, was originally aiming for 40..)
Half of this data (HA) was taken from the city Bortle 9. The other half (OIII) is from the desert (Bortle 4).
HA filters block so much of the light pollution (more than the OIII filter) so it was no issue imaging the HA from the city.

Thor’s Helmet is what Episode 15 of Galactic Hunter is all about! If you haven’t seen the trailer yet, take a look here: https://www.youtube.com/watch?v=GE0N4v-90Xw , you’ll likely have a laugh

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.
