Pano-Mosaic - Cloudy with a Chance of Fusion

A visit to the stellar foundries in the heavy-industry district of the springtime night sky. Another in a series of 2-panel widefield mosaic panoramas in my collection.

The version marked Final is an HOO narrowband rendering from the STC duo filter subs. One can zoom into M16 and see details of the core nebulae there! To render this version I treated the OSC data as a conventional color image and deBayered these subs with the VNG algorithm as usual.

For the SHO palette versions, rather than deBayering with VNG, PI's SplitCFA process was used to separate Ha, OIII and SII CFA subarrays and these three channels were drizzle stacked independently, so no VNG induced mixing between the NB channels occurred. This yielded a cleaner easier to manage result. It avoided the need to run Topaz Lab's Denoise AI on the SHO renderings, with less "violence" done to the shape and smoothness of the stars.

Plenty of ionized hydrogen in this scene. Hydrogen is a lightweight invisible gas that with sufficient time and energy is transformed into sentient beings with telescopes.

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.
