Lying along the plane of our Milky Way galaxy, numerous nebulae and star clusters can be found in the constellation of Auriga, the Charioteer:

IC405, the Flaming Star Nebula is the largest nebula in the right half of this photograph. Its clouds of gas and dust lie about 1,500 light-years away and are ionized by the ultraviolet radiation from nearby hot O-type star AE Aurigae. The latter is a so-called runaway star, likely ejected from the vicinity of the Orion Nebula millions of years ago and since travelling through space with a velocity of 100km/sec.

IC410 is an emission nebula in the lower center of this picture. Its clouds of glowing hydrogen gas were sculpted by stellar winds and radiation from the embedded open star cluster NGC 1893. Peculiar are the two pillar structures that give this nebula the name Tadpole Nebula.

IC417 and NGC 1931 are also dubbed “The Spider and The Fly” and are located in the lower left.
These represent young, open star clusters still embedded in their natal hydrogen gas clouds.

NGC 1907 is another open star cluster. It contains around 30 stars and is over 500 million years old.

Messier 38, or “Starfish Cluster” as it is called, can be found in the upper left corner. This open cluster of stars is 3,480 light-years away from Earth.

This is a stack of 3 hours each for RGB and H-Alpha data, taken on December 18th 2020 at my mountain site (970m elev.) in rural Upper Austria.
Nikon D750 with Skywatcher Espirt 100 (reduced to 412mm f/4 using a Ricciardi reducer) and a 7nm H-Alpha filter. Tracking with Skywatcher EQ6-R, Autoguiding with MGEN-3. Processed with Astro Pixel Processor, Starnet++ and Photoshop.

P.S.: I reprocessed this data in March 2023 using the Xterminator-Tools from Russell Croman.

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.
