The NGC3190 group of galaxies (Arp 316) in Leo (2015)

NGC3190 is the principal galaxy of the NGC3190 group, which involves other bright nearby galaxies NGC3185 and NGC3187, as wel as NGC3221, NGC3177, NGC3162 and possibly the galaxies surrounding NGC3227, 2° to the SSE. NGC3190 is a highly inclined spiral galaxy with a large, bright extended core in a smooth outer enveloppe. The principal dust lane is thick and somewhat inclined to the core of the galaxy: it is disturbed to the NNW, where a tidal interaction with NGC3187 may have occured. Distance 54 mly. Angular size 4.4'x1.5' . Diameter 69000 ly. (From Mark Bratton's " The complete guide to herschel objects", Cambridge university press) . Object H44_2 in Herschel's catalog, where the _2 stands for the Faint nebulae class objects.

Le groupe NGC3190 ou Arp316, distant d'environ 55 M.a.l. , dans la constellation du Lion. Image LRGB de 120, 21, 21, 21 mn. C8 avec réducteur, f=1350mm, D=200mm.

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.
