IC 2177 more commonly known as the Seagull Nebula is a reflection nebula between the constellations Monoceros and Canis Major around 3,700 light-years away from Earth. The seagull shape is defined by the head (NGC 2327) and the wings (IC 2177 itself). This Ha-rich region of cosmic dust and gas clouds glows in the red light of ionized hydrogen and is over 250 light-years in diameter. I chose the SHO palette for this one which resulted in a myriad of different ways of displaying the Ha and Sii rich signals. Also being a mosaic this had its challenges of matching the palette between panels and any fine gradients if any between each.

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.
