Data Acquisition from 2019-11-24 until 2021-01-17

DSO Color Mapping: Stars RGB, Nebulae Modified Hubble Palette

Original Image Scale: 4.00

Note: This scope is located at Sierra Remote Observatory. I personally configured and installed this scope and make regular trips to SRO to perform maintenance and upgrades. When not on site, I operate the scope nightly from home using a remote desktop application.

This is a dynamic looking region of the constellation Auriga where spherical nebulas appear to be shot toward each other. The image includes the nebulae Sh2-232, Sh2-235, Sh2-231, Sh2-234 and LBN 796, among others, and the open star clusters M38 and M36.

The eyeball looking nebula (Sh2-232) has been mistaken for a planetary nebula, but none of the round or semi-spherical objects in this field of view are actually classified as PNs (per Galaxy Map and SIMBAD). In fact, the big fuzzy ball in the lower left center (right above cluster M36) does not seem to have any designation at all and is merely a part of the greater nebula LBN 796.

A 2012 paper suggests that these unusual forms are all part of an expanding shell, the result of an ancient supernova. In turn, this shell exists within a larger molecular cloud. which is located 1800 pc from Earth. By comparison the two clusters are much closer, of course: M36 (bottom center) is 1330 pc distant, and M38 (center right) lies only 1066 pc away.

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.
