Cygnus Loop SHO (Brent Cooley)

Celestial hemisphere: Northern · Constellation: Cygnus (Cyg) · Contains: 52 Cyg · IC 1340 · NGC 6960 · NGC 6974 · NGC 6979 · NGC 6992 · NGC 6995 · Sh2-103 · The star 52Cyg · Veil Nebula

Cygnus Loop SHO

This is an custom 2x drizzled (reduced 50% for AstroBin) SHO-type narrowband image of the Cygnus Loop, the shell of a supernova remnant. The image was taken over many nights in 2020. Most images of this area are HOO (Ha and OII only) bi-color images. This image includes SII but I did not use it as part of the red channel. Instead, I blended 50% SII and 50% OIII for green which results in a more distinct color palette. I'll be adding an HOO-style palette version in the coming days.

This loop has distinct parts which go by many catalog entries and names, including:

* NGC6960 / Witch's Broom / Western Veil Nebula

* NGC6992 and NGC6995 / Eastern Veil Nebula

* Pickering's Triangle

* Veil Nebula

The cause of the explosion, which likely remains as a neutron star, has not yet been found. Based on scientific studies and calculations, it is estimated to have been roughly in the center of this image.

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.
