SH2-222 - Northern Trifid Nebula (Joe Matthews)

SH2-222 - Northern Trifid Nebula

Revision title: SH2-222 cropped

I finally collected good data on SH2-222, (My first attempt on this target,2024/02/02, I shot about 11 images) checking my data afterwards revealed my optics were just dirty. So after a good cleaning I collected about 5 hours worth of Data on SH2-222. I am happy with the post processing and am considering collecting maybe another hour or so on SH2-222 tonight. I am not sure if the extra time on the target will be worth it, but just maybe it will. So it’s a toss up, between more time on SH2-222 or image M78.

I downloaded GraXpert a few months ago to see how it performs vs SIRIL on Gradient removal. In some cases GraXpert does a decent job, but on most of my other collections SIRIL does a much better job, in my opinion. My first go with SH2-222 I used GraXpert and I thought it did a good job, and I finished post processing and was somewhat happy with the result. I decided to give it a a go using SIRIL and before noise cleanup the result was far better. So for now I think I will stick with SIRIL for most of my post processing work.

NGC 1579 (also known as the Northern Trifid) is a diffuse nebula located in the constellation of Perseus. It is referred to as the Northern Trifid because of its similar appearance to the Trifid Nebula, which is located in the southern celestial hemisphere of the sky. It is a H II region, a region of star formation.[4]The star cluster contains the emission-line star LkHα 101, which provides much of the ionizing radiation in the nebula.[5]NGC 1579 lies within a giant molecular cloud known as the California Molecular Cloud.[6

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.
