IC 2177 - Seagull Nebula

The Seagull Nebula, IC 2177, looks more like a pterosaur to me. Its head is an HII region about 1.1 kpc away surrounding the hierarchical triple pre-main sequence star system HD 53367, in which the primary in the binary as well as the triple companion is a Herbig Ae/Be star. These are intermediate-mass (2-8 solar masses) pre-main sequence stars that are still collapsing onto the main sequence, ie. they are not yet depending on hydrogen fusion to produce energy; gravitational contraction is their primary energy source. It won't be long, astronomically speaking, before they reach the main sequence.

This was tough -- there are a lot of stars in this field. I am trying out Astro Pixel Processor. I used it for stacking and calibration, background calibration, and photometric calibration on the stars, then stretched and processed the result in Photoshop, using Star XTerminator to separate out the stars.

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.
