NGC 1579 - Northern Trifid

Mostly prominent in LRGB, however, the nebula itself is bright in Ha. Processing was easier using only a small contribution of the total Ha due to the skewing of colors in the nebula from reddish-orange to more pink hues without any additional details. The original stacked image was somehow very short on the color blue which was evident within the bluish nebula IC 2067, so an additional 70 minutes of blue captured with my SVX-102T seemed to solve the color problem.

See also the additional images for starless versions of Ha and Lum data. I've been using Russell Croman's StarXTerminator (for fee) module in PixInsight lately to remove stars and it's impressive how it'll remove stars yet leave behind faint fuzzies. A couple of the brighter objects can be seen in the starless Lum image.

The Northern Trifid nebula (NGC 1579, Sh2-222) is a diffuse nebula in Perseus located about 2100 light years distant and is 3 light years across. It has a similar appearance to the more popular and well-known Trifid Nebula in Sagittarius. The star cluster contains the emission-line star LkHa 101 which provides much of the ionizing radiation in the nebula and is also a strong emitter of Ha light.

Imaged over several nights: Oct 18, 19, and 31; Nov 4, 5, 7, and 24, 2021.

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.
