NGC 6946

Revision title: Version B

Link: https://www.robertomarinoni.com/

The spiral galaxy NGC 6946, located on the border between Cygnus and Cepheus constellation, is one of the closest neighbours of the Local Group, being its distance from the Milky Way only 18 million light years.Due to its small inclination with respect to our point of view, it shows a detailed view of many active HII regions inside its spiral arms.
This galaxy is also known as “Fireworks Galaxy” due to the several supernova exploded in the latest 100 years (10 supernova from 1917 to 2017)

Version A is the original image processed in 2021.
Version B is the processing of exactly the same 2021 data but using the modern "dark room" tools (suite XTerminator) and, above all, increased personal skills in the processing.
The result is very different from previous processing: more details in the galaxy, better stars (smaller) and also traces of IFN all around the field (to better highlight IFN I decided to take the background not so much dark as in my "standard" processing).

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.
