Sh2-312 (The Pyxis Nebula) and NGC 2888

I saw a bright, 10 degree wide, flowing HII nebula while browsing Aladin and I thought it would be fun to image it. It turned out to be Sh2-312. I only captured the first 1/3 of it here. It is called the Pyxis Nebula, as you might expect since it is located in the southern constellation of Pyxis at a declination of -28 degrees. I could not find anything of detail on this nebula.

Pyxis is the Latin word for "box". The full name of the constellation is Pyxis Nautica, which means "mariner's compass box". This is one of the 14 new constellations devised by the French astronomer Nicolas-Louis de Lacaille in 1752 when he visited the southern hemisphere. All but one of these new constellations were named after instruments which symbolized the Age of Enlightenment.

I like the swirling nebulosity in the bottom right of the image. I also find interesting the thin darker band with no nebulosity which runs parallel and above the leading edge of the nebula. I thought that perhaps this was just an artifact, but I see it on Aladin as well so I believe it is real.

Hiding behind the most intense region of the nebula is an elliptical galaxy, NGC 2888. It is a magnitude 13 galaxy that is located 110 million light years away. It spans 1.7 arc-minutes in our apparent view, which corresponds to a diameter of 60,000 light years.

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.
