NGC4565 Needle Galaxy

Our own Milky Way Galaxy lies perpendicular to the Needle Galaxy (NGC 4565) and so we see it almost perfectly edge-on. It appears very thin from this perspective and that's how it earned its name. I can imagine someone in the Needle Galaxy looking at us in their telescope. They would see us edge-on and probably name our galaxy the Needle Galaxy. And maybe they call their own galaxy the Milky Way! Of course, since it takes 50 million years for light to travel between our respective galaxies, they would be seeing us in Earth's Early Eocene Period just after the age of dinosaurs. The bulge in the center of this galaxy suggests that it is a barred spiral galaxy. You can also see a small warp in the dark lane surrounding the galaxy that is probably due to gravitational interaction with one of its small companion galaxies. If you look closely, you can just make out one of these companion galaxies above and right of center.

I made this image from a stack of twenty 300-second exposures that I shot at 2310mm focal length, calibrated with 20 each dark, flat, and dark flat frames, then post-processed with StarNet++ and Photoshop.

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.
