NGC2359 Thor's Helmet Bi-Colour

NGC2359 / Thor's Helmet my first completed image of 2021 with the clouds of La-Nina wreaking havoc with our skies!

11.96 thousand light years away and 30 light years in size. It is produced from a rare type of star, a Wolf Rayet type that is shedding energy at a great rate energizing the gases which are shock waves. WR7 is around 280,000 times brighter than our Sun!

The unique shape is thought to have formed by the interaction of a nearby molecular cloud. Otherwise, it would be more circular and similar to the Bubble Nebula.

Exposure time totaled 6 hours of 3-minute exposures. 3 hours Ha and 3 hours Oiii which were combined to create the colour image. The luminance channel was then extracted and processed to recover detail and sharpened.

Gear used: - HEQ5 Pro mount, ASI1600MM Pro, Antlia 3,5Nm Ha & Oiii filters, guided with a 50mm refractor. Image acquisition was done with SGP and PHD2 for guiding.

All post processing done in Pixinsight latest version.

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.
