The Flaming Star Nebula (IC 405, SH 2-229, Caldwell 31) is a massive emission nebula and reflection nebula, 1500 lightyears away in the constellation Auriga. IC 405 is about 5 lightyears across, so that's roughly 30 trillion miles (47 trillion kilometers) of dense clouds of ionized hydrogen. With the stars in the field of view removed (or just de-emphasized) you can really see the motion in the clouds of hydrogen and interstellar dust. It is the intense radiation and stellar winds from energetic stars (especially AE Aurigae, a rather large blue O-type main sequence star) that drive these clouds through space, but that motion and the complexity of the cloud structures is not as easy to see with all the stars in the way. Imaging Notes: 60 x 240sec subs stacked in DSS. William Optics GT81 Apo refractor, 6nm Astronomik Ha filter, ZWO ASI 1600MM-Pro monochrome camera. Star removal: StarNet++

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.
