ic749 and ic 750

A pair of interacting?? galaxies in Ursa Major, not far from the famous 'Box'.

Not as impressive but quite interesting.

IC749 is a 12th magnitude spiral galaxy (type SAB(rs)cd) in Ursa Major (RA 11 58 33.9, Dec +42 44 03)

Apparent size 2.3 by 2.0 arcmin.

IC 750 is a magnitude 11.9 spiral galaxy (type Sab?) in Ursa Major (RA 11 58 52.0, Dec +42 43 20)

IC 750's recessional velocity of 700 km/sec is too small to yield an accurate Hubble expansion distance, as it corresponds to a distance of less than 35 million light years, much less than redshift-independent distance estimates of 60 to 120 million light years. Given its apparent size of 2.55 by 1.3 arcmin, the Hubble expansion distance yields a size of about 25 thousand light years, which is probably too small for its regular structure. The redshift-independent distance estimates suggest a more reasonable size of 45 to 90 thousand light years.

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.
