My BEST Picture of the Andromeda Galaxy

This is the best capture of the Andromeda Galaxy I've ever taken and it was only 2.62 hours. I stuck to very short exposures of 15 seconds to combat light pollution. This is also a mini-tutorial as I show all of the processing steps I took.

Here are some facts on the Andromeda Galaxy:

The Andromeda galaxy (M31) is approximately 2.5 million light-years from Earth.

Andromeda contains 1 trillion stars.

The Andromeda Galaxy is the most distant object you can spot with your naked eye.

The galaxy gets its name from the area in which it appears, the constellation of Andromeda.

Andromeda is approaching the Milky Way at approximately 86 miles per second.

Abd al-Rahman al-Sufi made the earliest recorded observation of the Andromeda Galaxy in 964 AD.

Andromeda was once known as the Great Andromeda Nebula - before anyone knew what a galaxy was.

Andromeda being a galaxy outside our own was hypothesized as early as the 17th century (Island Universes).

Edwin Hubble settled the debate on galaxies in 1925 by discovering a
variable star in Andromeda.

Andromeda has a double-nucleus, likely because two smaller galaxies merged together.

Andromeda has various satellite galaxies including 14 dwarf galaxies.
