Helix Nebula - NGC 7293

After imaging the Eagle Nebula that night I went on to the Helix Nebula.

For me, this one doesn't exceed 20° altitude. To the end of imaging, guiding appeared to be a complete mess based on the elongated stars I got. Closer inspection of the single subs revealed that the different colors of the stars actually were pin point. But the red part of stars were not exactly in the same spot like the blue/green part of the stars making it look elongated. The nebula was obiously so low that the atmosphere worked as a badly color corrected lens. DSS was fortunately able to take care of the problem by aligning the different channels.

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.
