NGC2359 - Thor's Helmet

NGC2359 is an emission nebula roughly 12,000 light years away from Earth in the constellation Canis Major. It is caused by an extremely hot central star called WR7 that is likely to be in a brief pre-supernova period of it's evolution. WR7 is 229,000 times brighter than the Sun and 13 times as massive. The bubble of gas around the star is ionized by the powerful solar winds, and this is what causes the region to emit light. The shock waves moving away from the star are interacting with nearby molecular material and this is what causes the unique shape of this nebula, resembling Thor's Helmet.

It has been a great season of clear nights and decent seeing in South Florida enabling me to go for 20hr plus integration times as was the case here. This is rendered in an HOO pallet which I preffer for this target.

Thanks for stopping by!

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.
