With wings that span about 250 light-years, the Seagull Nebula soars across the border between constellations Canis Major and Monoceros. The head of the gull, cataloged NGC 2327, is a dusty region surrounding a massive star (the region is also cataloged Gum 1, vdB 93, and Sh2-292). The broad, sweeping wings are cataloged IC 2177.

The Ha, OIII, and SII data for this image were collected in January 2019. This object appears just above the roof of my house for a few hours a night, so gathering the data was a challenge. To maximize the few collection hours available, I did 2x2 binning of the OIII and SII data, using the channels primarily for color mapping. Much of the nebular structure is seen in the Ha channel, which was collected 1x1. In reviewing the folders on my storage drive this week I found some “long-lost” RGB data (also collected 2x2) that I collected at the same time and had never processed (yes it is still cloudy nearly every night here in Monterey, CA so I have time to cleanup). This image combines that 2019 narrowband data with the newly discovered RGB data in an NBRGB rendition. To achieve a more “natural” color palette, I used Steve Milne’s natural narrowband SHO formula.

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.
