Galaxy duo NGC4298 and NGC4302 in Coma Berenice (2016/2017)

These two galaxies may form a physical pair but there is no evidence of tidal distortion in either galaxy. Both have very similar radial velocities (1084 km/s et 1099 km/s) corresponding to a distance of 49 mly. NGC4298 is a multi-armed spiral galaxy with a very small, round brigter core and knotty condensations and dust patches in the arms. NGC4302 is a very thin spiral galaxy, edge on, with a brighter core but no evidence of bulge. The core is largely obscured by a narrow, prominent dust lane which runs almost the entire length of the galaxy's disc. Both galaxies were discovered by W.Herschel on 8 april 1784 (objects H111_2 and H112_2 in his catalog, were _2 stands for "Faint nebulae" in his classification scheme of deep sky objects. Their angular diameter are 3.3'x1.3' and 5.4'x0.6', respectively. (From Mark Bratton's "The complete guide to the Herschel objects", Cambridge University Press)

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.
