The "Silver Coin Galaxy" NGC253 (Scl) - atmospheric discoloration

The "Silver Coin Galaxy" in the constellation "Sculptor" is only a maximum of 17° above the horizon when passing through the meridian in our latitude (47.5°), i.e. deep in the haze polluted by light and dust. In addition, it must be photographed through the lightdome over Garmisch-Partenkirchen and also just above the ridge of the "Wetterstein" mountain range, which lies directly behind it and runs like a great wall from east to west.

In the long nightsfrom October 30th to November 3rd, 2024 - and around the new moon - I was only able to collect a total of just under 5 hours of exposure time due to the persistently foggy weather conditions and frequent veiled clouds. Of the 98 images created in this way, only 65 images were usable ... the rest were just muddy and terrible.

The color shift caused by the atmospheric conditions is interesting: everything has become a bit yellow-light-brownish - including the stars. Unfortunately, the photometric calibration in Siril couldn't change anything. So I decided to make the most of it and consider this image as a document of the astrophotographic conditions and possibilities specifically in our Alpine valley.

I love the heaven -
and heaven loves me.

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.
