Seagull Nebula - Gum 2 (SHO with RGB stars)

The second picture from 2023 is also the result of a collaboration between me and my amateur astrophotographer friend Lino Benz, who has now become my official ionized sulfur dealer

In fact, in this image of the Seagull Nebula, I merged the signal acquired by me last year with L_eNhance filter (from which I extracted Ha and OIII) with those acquired a few days ago by Lino with SII and UV/IR-cut filters. The end result is a SHO composition with RGB stars, hope you like it.

The Seagull Nebula (also known as Gum 2, sometimes erroneously known as IC 2177) is a diffuse nebula visible on the border between the constellations Canis Major and the Unicorn. The nebula is located about 9 degrees northeast of the star Sirius and extends two degrees into an area rich in hot, blue stars of recent generation.

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.
