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.

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.
Dismissals 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.
