Sh2-115, Sh2-116, and the Shock Bows

This image was inspired by a narrowband image by Christoph Lichtblau where he pointed out that these shock bows (presumably from a supernova explosion) are rarely imaged although there are plenty of images of Sharpless 115 and 116. The shock bows are the Ha emitting curved structures below the Sharpless objects, apparently catalogued as LBN380 according to the annotations by the Astrobin plate solving.

The image was taken with my dual RASA rig and I did the experiment of binning the data 2 x 2 (by debayering using Superpixel in PS). It worked out quite well I think. The moon was up so I thought such rather faint structures like these would benefit from increasing the S/N ratio by binning.

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.
