NGC4565 ou la "galaxie de l'aiguille", de dimension similaire à la Voie Lactée, située à environ 30/50 millions d'années-lumière ; accompagnée de quelques galaxies plus lointaines (NGC4535 et NGC4562).
Beaucoup plus loin dans l'espace, on distingue la structure de IC3543 (280 millions d'années-lumière) ou encore IC3546 (300 millions d'années-lumière).
Image principale réalisée à la TSA102, mixée avec une image réalisée au C8 pour gagner en détail dans NGC4565 et les galaxies proches.

NGC4565 "Needle Galaxy", a galaxy probably very similar in size and structure to our own Milky Way, 30/50 millions LY away ; with other more distant galaxies (NGC4535 and NGC4562).
Much further in space, we distinguish the structure of IC3543 (280 millions LY) and IC3546 (300 millions LY).
Main field made with TSA102, mixed with an image made with C8 in order to gain some details in NGC4565 and galaxies around.

If this user has been harassing you, and you shadow-ban them, all their activities on your content will be invisible to everyone except themselves.
They will not know that they have been shadow-banned, and the goal is that eventually they will get bored while having caused no harm, since nobody saw what they posted.
You will remove your shadow-ban on this user, and their comments, messages, etc, will appear again on your content.
Please note: You are on a Free account, and when you delete an image, your upload counter does not decrease (unless the image is deleted within 24 hours of uploading it). The Free account is not a way to keep your most recent or best 10 images on AstroBin, but a trial period for you to decide whether or not a paid subscription is worth it. For more information, please click here.
The image will be permanently deleted and cannot be recovered. All its revisions will be deleted too. Are you sure?
You will delete all other revisions (if any), and the originally uploaded image, leaving the current revision as the final and only version of this image.
