My Astrophotographs of 2021
NGC 7000 the North America Nebula
NGC 7000 (left) the North America Nebula, is the name of a diffuse gas nebula in the constellation Cygnus in the northern sky. The nebula got its name because of its shape, which is reminiscent of a map of the North American continent, and is approximately 2,500 light-years away.
IC 5070 (right) the Pelican Nebula, is an emission nebula in the constellation Cygnus, approximately 2,000 light-years away.

M 31 the Andromeda galaxy
M 31 the Andromeda galaxy, also Andromeda Nebula or Great Andromeda Nebula, is the closest spiral galaxy to the Milky Way, around 2.5 million light-years away. It is located in the eponymous constellation Andromeda and is the most distant object that can be observed with the naked eye under good conditions without technical aids. The Andromeda Galaxy is similar to the Milky Way. There are dark dust bands, star formation regions and over 200, possibly 500 globular star clusters in the outer area. Their individual stars can also be observed in ever larger areas.
The galaxy has a massive black hole of around 100 million solar masses at its center, spiral arms extending from it to a distance of around 80,000 light-years, and its halo extends over a million light-years.

Messier 33 is also known as the Triangular Galaxy and the Triangulum Nebula
Messier 33 is also known as the Triangular Galaxy and the Triangulum Nebula, is a spiral galaxy with dimensions 70′ × 40′ and a total brightness of 5.7 mag. in the constellation Triangle in the northern fixed star sky. This makes it the second brightest spiral galaxy in the night sky after the Andromeda Galaxy and one of the closest to us. However, its brightness is spread over a larger area, so that under normal conditions it is not visible to the naked eye, but only visible through binoculars.
Die Entfernung beträgt ca. 2,76 Mio. Lichtjahre.
