Thor's Helmet

HaRGB composit of Thor's Helmet. This is my first insertion of RGB stars back into an RGBHa substrate image.
This was quite a dissapointing capture because I had to throw away about 4.26 hours of wonderful OIII data that was polluted with the Halos.
So instead I turned the intended HORGB image into an HaRGB image. The nebula is rich in OII data and it is such a shame to loose that wonderful blue, but here it is anyways.

Going after the OIII again with new a filter which should arrive tomorrow! You have to click into the image and zoom to see the full glory and resolution of the nebula.

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.
