NGC 2359 Thor's Helmet

Thor's Helmet has been a target on my list for years but with my scope in upstate New York I'd never been able to image it. Over the past year and a half I have been working to build an observatory in South-East Arizona and I finally have the horizons and the skies to shoot such a southern target. Even at 31 degrees, Thor was never visible for more than a couple hours, so acquisition happened little by little over many weeks and in the end I was quite happy to have a little more than 80 hours of data.

I worked with @Charles Hagen to approximate a natural color distribution from the Ha and Oiii data and used his independent starless processing technique to process this data.

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.
