Sh2-216 and 221 in Auriga with Astrel8300 (tommy_nawratil)

Celestial hemisphere: Northern · Constellation: Auriga (Aur) · Contains: 12.80 · 426 Hippo · B25 · NGC 1724 · PK158+00.1 · PK160-00.1 · Sh2-216 · Sh2-217 · Sh2-219 · Sh2-221

Sh2-216 and 221 in Auriga with Astrel8300

Sharpless 216 is a huge and dim planetary nebula, the bubble at right in this picture. Sharpless 221 is an ancient Supernova remnant, even dimmer at left, typically built up of lots of filaments. Both are glowing at Hydrogen and Oxygen lines, and their distinctly different appearance make for a great motiv. The intense red blob north of 221 is Sh2-217 and the smaller one next to 221 is Sh2-219. Between the two majors here sits another medium size H-Alpha region without Sharpless number, dubbed BFS44, that contains a dark nebula called B25. The whole region is very near to bright Capella, which resides just left of the field.

Lots of numbers, but nothing in the mouseover :-)

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.
