SH2-275 a Rosette in 22 minutes

A second attempt with the Samyang/183C combo at f2. This time the rosette, in just 22 minutes. For some reason Siril was not happy calibrating and stacking this set, so used Han Klein’s excellent ASTAP. Processed in Siril with Starnet extraction and recomposition. No change to set up from my last image, and stars still wonky. I am impressed with the amount of nebulosity, and stars look a little better with less stretch. For a lovely clean and natural image, see @Björn image here. If you ever doubted the power of AI tools for 'improving' your astro images, I've loaded up the original basic recomposition as mouseover - the final image after use of Deep Sky Details Astrosharp and Astroclean (denoise) - 'night and day', or should that be 'day and night!'

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.
