It is about 30 million light-years away from Earth and is best viewed in our fall season. A spindle-shaped galaxy that is viewed almost edge-on, it is also known as the Silver Sliver Galaxy, the Outer Limits Galaxy, and the Silver Needle Galaxy.
C 23 is visible in small to moderate size telescopes as a faint elongated smear of light with a dust lane visible in larger apertures. Its outskirts are populated by multiple low-surface brightness, and vast substructures, like giant streams that loop around the parent galaxy. The bulge and the disk are surrounded by a flat and thick cocoon-like stellar structure.
In popular 1960’s culture, NGC 891 appears alongside M67, the Sombrero Galaxy, the Pinwheel Galaxy, NGC 5128, NGC 1300, M81, and the Andromeda Galaxy in the end credits of the Outer Limits TV series, which is why it is occasionally called the Outer Limits Galaxy.
This image was taken December 19th, 2023 and January 31st 2024 with a RC8 telescope at 1625mm and ASI071MC camera riding an EQ6r Pro mount. I hope you enjoy this galaxy image.
Cheers!
