IC2177 The Seagull Nebula in Narrow Band

IC 2177 is a reflection nebula in a region of nebulosity that lies along the border between the constellations Monoceros and Canis Major.
It is a roughly circular H II region centered on the Be star HD 53367.

Again, back to some old data with the new PixInsight tools and hopefully improved techniques. BlurXTerminator correction only is first applied to the channels. Then Manually calculated PSF values are used for a .2 Star Reduction with Non-Stellar Reduction turned off completely . Non Stellar Reduction is now only used at the end on the Starless Non-Linear before LHEQ and NoiseXTerminator. The GraXPert gradient tool didn't like the blue one bit so much jiggling of the grid points until it did what I had hoped for. A lot like DBE where less can be more but I think GraXPert is the bee's knees for now. I know there is a new DBE being worked on but, out-of-the box, GraXPert does an amazing job and is much quicker and easier to use then DBE.

The region around the Seagull deserves a wider field for sure as it is rich in other objects like star cluster, planetaries, HII regions and other reflection nebulae so I will add this to my list when I take my portable wide-field rig out west under darker skies.

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.
