Image Description Photographer
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. Telescope: PlaneWave 12.5",  Focal Length: 2032 Camera: ASI2600MC Pro, 250 exposures of 120s on 4/11/2023.

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
The Rosette Nebula (also known as Caldwell 49) is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. Telescope: ED127 Flattener/Reducer: .7 Focal Length: 678 Camera: ASI2600MC Pro, 75 exposures of 300s on 2/20/2023.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
