NGC 6992 - going batty (Tom Gray)

NGC 6992 - going batty

Revision title: Processed in SIRIL

I've been enjoying a run of clear nights, continuing to experiment with my new Star Adventurer mount - so many different configurations I'm starting to go batty. NGC 6992 makes a fine narrowband target for our still bright summer skies, but astro darkness is slowly returning, with nautical darkness for nearly 4.5 hours. I am now so confident with the simplicity of this mount, that I even went to bed for a few hours!

Same old processing in Startools, with star reduction and using the superstructure module to push back the starfield, with final noise reduction. Revision B (mouseover) is the same data processed in Nebulosity using levels and curves, star and noise reduction. I pushed this a bit too hard, but like the clean, sharp lines, even if the background is noisy. The Startools version may not look quite so sharp but has greater depth and saturation IMHO. Anyway I'm always interested in your feedback and comments.

[postscript - I have to say I’m really impressed with APP. Both for pre- and post-processing. My only gripe there is no manual, but useful tooltips and a very helpful third party guideproduced by Charles Bracken, and several video tutorials].

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.
