NGC 3923

Galaxy 3923, home of the supernova SN 2018aoz, and also having interesting structures, a kind of shell layers. In B you have the negative and you can see these structure better, as nebulosity in the diagonal crossing the galaxy. More integration time is needed, so I could try to double the time. Also a few galaxies are around.
It is not the best image processing but I will wait for the next images to add them and try a better technique for the image.

Title: NGC 3923 in negative

Description: I uploaded this version so the cloudy regions around NGC3923, kind of shell structure, can be spotted a bit more clear that in the full colour image.

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.
