Sh2-115 Emission Nebula (The Royal Astronomical Society of Canada Robotic Telescope) In Foraxx with RGB Stars

At this focal length, Sh2-115 looks a little different than the other images I've seen of the region - the long straight striations of nebulosity are just out-of-frame. The SII data supplied with this dataset was pretty faint, and the OIII was mostly the halo around a few of the stars, and ended up creating some interesting problems when combined (crazy purple halo!) After experimenting with both SHO and Foraxx, Foraxx won by a landslide. the RGB stars re-screened into it very nicely, and for some reason I always prefer the hydrogen to be red.

Sh2-115 is an emission nebula illuminated by stars in the Berkely 90 cluster, and was imaged in July & August 2021 by the RASC Robotic Telescope. This was a really nice dataset with nearly 40 hours over many nights in July & August - many thanks to the RASC imaging team for capturing this data!

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.
