IC 2177 / vdB 93 / Sh-292 / Gum 1

This object, the Head of the Seagull Nebula, is an emission nebula located in the constellation of Monoceros at a declination of -10 degrees. It is also known as Gum 1 and Sh2-292. The blue reflection nebula within is vdB 93.

This object is primarily a hydrogen region, with the gas ionized by the bright embedded 7th magnitude central star HD 53367. This star is the Seagull’s “Eye” and is 20 times the mass of our sun.

I particularly like the dark dust lane which streams left from the central star and the ionized fronts of gas at the right edge of the image.

This image of vdB 93 is a small part of the overall Seagull Nebula, seen here in a narrowband image:

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.
