Even this image should be perceived as an image in progress I decided to show it now.

The reason is obvious as one can never trust the weather conditions in CPH, DK :-)

It's an IRpass-RGB color image & sub exposures were: 22x240sec+63x120sec.

Subs/frames was calibrated with darks & flats.

As usual it's taken in a light polluted area, Bortle 6 sky looking south, Bortle 7 sky the other directions/surroundings.

My home build observatory is placed in my front yard/in the "red light" pollution zone, have a look here,

Red Zone

Kind regards Niels

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.
