NGC3628 or Arp 317 in Leo (2015)

Member of the famous Leo trio, this is a very large and very bright spiral galaxy seen edge on, also designated as Arp 317 due to its complex and unusual structure.
Distance: 34 Mly. Diameter: 148000 ly. Angular diameter: 14.8'x3.0'.

Galaxie NGC3628, une des 3 formant le trio du Lion. Image faite au C8 avec réducteur de focale (f=1350mm), 20x3mn en luminance et 7x3mn pour chacune des couches R,V, B (binning 2x2), traitement assez basique sous pixinsight (pas de déconvolution de la résolution ou de lissage du fond) . Cette spirale vue par la tranche a une forme inhabituelle et un énorme nuage de poussière absorbe la lumière du noyau. Elle est située à 34 millions d'années lumière et son diamètre apparent est de 14,8 x 3,0 arc min

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.
