Target Description:
Additional Images:
B a more expansive view of these galaxies
C a blinked comparison with a Hubble image

These two galaxies are just beginning to merge into a single object, probably becoming an elliptical galaxy. Earlier near passes of the two have stretched gravitational tails and loops from both galaxies with a faint streamer below NGC 2207 and another one to its upper right. IC 2163 has its own prominent tail. Internally, the image shows spiral arms abutting one another or terminating abruptly. The blinked images (D) show this more clearly.

In image B, I counted 30 small background galaxies of various morphologies.

Processing Description:
This image data set came with both Ha and L subs. I processed three data set versions: RGB, LRGB, and LHRGB. Of the three, my best result, in terms of sharpness, detail, and color, was the simple RGB subset, which I show here.

Statistics:
Distance: 80M ly
Apparent Magnitude: 12
Average Surface Magnitude: 23
Apparent Span: 4.3x2.8 arc-minutes
Pixel Span at Target: 1.4E14 km

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.
