Seagull Nebula (IC2177)

This is an SHO narrowband image of the Seagull Nebula (IC2177), 3,700 light years from Earth. I have sourced the following information from Astrobin and other sources. It is a vast star-forming region, the "wings" span about 200 light years tip-to-tip. Many of the stars in this region are massive and hot. On the lower left there is an incredible structure VdB 95, a reflection nebula caused by a supernova, with a huge star HIP34301 which has created a Bow Shock Wave (BSW), clearly visible. I have included an image annotation to highlight the individual structures. Sh2-292 is the “Seagull Head” and is both an emission nebula and a reflection nebula. The luminous star HD53367 is the “eye”, it is 20 times more massive than our sun. Sh2-296 is the “wings of the Seagull”, and NGC2327 is a small reflection nebula apparently often mistakenly called the Seagull Nebula. This image was created using PixInsight in a training session with Ron Brecher.

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.
