The Little Cub and ngc 3359

The Little Cub and spiral galaxy ngc 3359 are located in the constellation Great Bear (hence the name "Little Cub") at a distance of approximately 50 - 60 Million Light years.
The Little Cub is a "Blue Compact Galaxy" or an "extremely metal-poor star forming galaxy". It has a very low oxygen content, ant its stars contain mostly only Hydrogen and Helium. This type of galaxy therefore resembles galaxies that formed when the universe was still young.
The Little Cub is gravitationally bound to Milky Way size ngc 3359, and is actually being ripped apart by it. Scientists have found a stream of molecular Hydrogen which stretches from Little Cub towards ngc 3359.
Little Cub has a brightness of approximately magnitude 19.5 - 20. For comparison, the red star just below the dwarf galaxy is of magnitude 22, very close to what I can capture with my telescope and camera from my backyard.

This image is very much a work in progress. Atm, I am collecting more Ha, and when the moon is out of the way, I will also try to collect more Luminance.

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.
