IC 405 Region in Auriga

Link: http://www.jthommes.com/Astro/IC405.htm

The primary object in this image is IC405. It's common name is the "Flaming Star" nebula. The star responsible for this name is AE Aurigae (also known as HD 34078). This star is thought to have originated in the Orion star forming region and was ejected some 2.5 million years ago. As such, it did not originate in the emission nebula but is instead passing through at a high speed - producing an energetic bow shock. IC405 is cataloged (more or less) in several other catalogs and is also known as Sharpless 229, Cederblad 42, and LBN 795. The large open cluster Melotte 31 is also partly visible in this image. This cluster was hard to pin down. The descriptions have this cluster as quite large in angular span - one reference says 135 arc minutes; catalog notes say one degree square. I have likely indicated its span too small in my annotated image. The emission nebula LBN 791 is the "tail" of the Flaming Star extending south. The blue component of the Flaming Star nebula is a reflection nebula known as vdB 34. Also in this image at the lower edge are several small objects that SIMBAD describes as reflection nebulae - but the are in an extra-galactic catalog so they may be distant galaxies. These objects and some of the brighter stars are identified in the annotated image. Horizontal FOV is approximately 140 arc minutes.

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.
