A Fire in the Sky (Sh2-54, M16, M17) (Bruce W Berry Jr)

A Fire in the Sky (Sh2-54, M16, M17)

I started working on this image some time last year, but ultimately, I decided not to post it and had forgotten about it completely. Until I recently revisited it a few months ago and wanted to see what I could do with adding more data. Anyhow here is the finished result. See below for details.

Thanks for viewing and Clear Skies everyone!

Tech info:
This narrowband image with RGB stars is two panel mosaic that was created using several different scopes and cameras. I collected the majority of the data was using iTelescope (19+ hours) and the remainder was taken from one-shot observations as well as one shot observation bundles from Telescope Live.
This data was stacked in Astro Pixel Processor and processed in PixInsight, with finishing touches applied in Photoshop.

Cameras: FLI PL16083; SBIG STL-11000M
Telescopes: Takahashi FSQ ED (530mm); Takahashi FSQ-106ED (382 mm)

Filters and Exposures

HA, OIII and SII Subs = 600 sec; Bin 1x1
RGB Subs = 300 sec; Bin 2x2

Ha = 12.5 hrs
OIII = 10.6 hrs
SII = 11.5 hrs
RGB = 2.0 hrs (1 hr per panel)

Total Integration Time: 36.6 hours

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.
