Cygnus Loop Mosaic - HSO with RGB Stars (Earle Waghorne)

Cygnus Loop Mosaic - HSO with RGB Stars

The Cygnus Loop is one of the most recognizable supernova remnants and includes the Western (NGC 6960) and Eastern (NGC 6992, NGC 6995 and IC 1340) Veils, Pickering's Triangle and the Southeastern Knot. It is around 2400 Light years from Earth and has a diameter of around 120 light years [1].

This became an exercise in how not to do a mosaic. I started to do two panels and then changed to 4 panels, to catch more of the filaments at the open end; also, because the camera angle was slightly wrong, I had to add an extra panel to complete the image. So it was more of a jig-saw puzzle. The overlapping plates made processing tricky but, thankfully, using lots of multi-band blending, APP stitched them together without edge shadows.

Processing nebulosity is something I still struggle with; in this case I wanted to bring out the faint strands without over processing the brighter areas. In the end, this feels like the best I can do right now.

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.
