NGC5396 (=NGC5375) A small galaxy in Canes Venatici. March-April 2020

NGC 5396 (=NGC 5375) is a rarely imaged small galaxy in Canes Venatici.

The core has an interesting form. I do not recall seeing anything like that in other galaxies.

Also there is a large number of tiny background galaxies in this region of the sky.

Revision B is a comparison with my last year attempt. Back then I've just started with astrophotography and I was still learning a lot. I believed that 4 hours was a long exposure

But NGC 5396 proved to me that a longer exposure time is required to image the deep space. Still it was a joy to actually get an image of a distant faint galaxy far far away!

The 681 unguided exposures 120 seconds each for the current image have been gathered in March and April 2020.

Thanks for looking,

Vitali

Description: This is an annotated image, where more than 150 galaxies are marked. First I've used the HyperLEDA database with PixInsight AnnotateImage script. When available, the galaxy name contains the visual magnitude and type of the galaxy. However the HypedLEDA data still did not contain many galaxies. So I went on a galaxy hunt and marked remaining galaxies, which I could find, with ???.

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.
