NGC 7331 Galaxy

I am really happy with this one. There were clouds all the time and i had to check every single frame just to see if i can use it. I was surprised that so many could be used (50 out of 60), but a lot of the subs were taken through thin clouds.

I tried longer subs this time and i must say that the image benefits from it. Postprocessing was easier than yesterdays image (which was taken with 1 min subs on a similar target).

NGC 7331 is a galaxy thought to be similar to the milky way, but back in 2000 scientists discovered that the core rotates in the opposite direction than the spiral arms. I wonder what caused this and i am really happy that our galaxy does not behave like this. Despite of this (or maybe because of this), NGC 7331 is a real beauty! I am also happy that some of the companions of this galaxy made it to the image. This bunch of galaxies is called "Deer Lick Group". What a name...

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.
