I wanted to see what I structure I could see in the "loosely" spiral galaxy, NGC4244, given that it is almost exactly edge on. There are several active star forming regions from hydrogen emissions (red) at what appears as a star in its core.
In the case of NGC4244, this is actually a very dense cluster of stars, known as a nuclear star cluster (NSC) at its centre of mass. Smaller, fainter galaxies tend to have NSC and not supermassive black holes at its nucleus or core. The opposite is true for much larger/massive galaxies where NSCs are most often absent. The Milky Way contains both an NSC and a supermassive black hole of roughly the same total mass.
The Silver Needle Galaxy is the member of the M94 group and is about 13 million ly away.

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.
