Image Description Photographer
M31 is located in the constellation Andromeda and is best observed in November. Boasting an apparent magnitude of 3.1, the galaxy can be seen with the naked eye, even in areas with moderate light pollution. Because it is such an easily observed feature in the night sky, it is impossible to say who discovered the Andromeda galaxy. However, Persian astronomer Abd al-rahman al-Sufi’s The Book of Fixed Stars from the year 964 contains the first known report of the object.

The Pinwheel Galaxy (Messier 101, NGC 5457) is a face-on spiral galaxy 21 million light-years away from Earth in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781 and was communicated that year to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries.  Telescope: PlaneWave 12.5”,Camera: ASI2600MC Pro, 20 subs, 30 flats, 20 darks.Gregg Bellman

Messier 83 or M83, also known as the Southern Pinwheel Galaxy and NGC 5236, is a barred spiral galaxy approximately 15 million light-years away in the constellation borders of Hydra and Centaurus. Nicolas-Louis de Lacaille discovered M83 on 23 February 1752 at the Cape of Good Hope.

M104, known as the Sombrero Galaxy (NGC 4594) is a peculiar galaxy of unclear classification in the constellation borders of Virgo and Corvus, being about 9.55 megaparsecs from the Milky Way galaxy. It is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster.  Telescope: PlaneWave 12.5",  Focal Length: 2032 Camera: ASI2600MC Pro, 150 exposures of 180s on 4/22/2023.Gregg Bellman
Southern portion of the Milky Way galaxy photographed with a Google Pixel 6 Pro Phone with no other equipment. The Pixel's "night-sight" mode was used with the "astrophotography" setting that automatically stacks images taken over the course of four minutes (!). The Lagoon and Triffid nebulae are visible along with Ptolemy's cluster, etc. Stars as faint as magnitude 8.5 appears in the photographSteuart Dewar

Images of the Antennae Galaxies (NGC 4038 and NGC 4039) were taken over a two year period (2015-2016) and required a total of 16.25 hours of exposure.  Specifically, 390 minutes of luminance and 195 minutes of RGB each. Ken Kattner
