Messier 31 - The Andromeda Galaxy | Astrophotography and Tips

The Andromeda Galaxy is by far the easiest galaxy to image for beginner astrophotographers! It is huge, bright, and is one of the most impressive deep sky objects in the northern hemisphere. In this post, you will find information, images, and tips to photograph the Andromeda Galaxy.

Object Designation: M31

Also known as: The Andromeda Galaxy

Constellation: Andromeda

Object Type: Galaxy

Distance: 2.45 million light-years away

Magnitude: 3.44

Discovered in: 964 (first known report)

Because of its diameter of more than six times that of the Moon, we recommend imaging this target with a small to medium size telescope, as the galaxy will not fit completely in the frame if using a larger instrument (unless doing a mosaic).

We have captured the galaxy many times using both DSLR and astronomy cameras, with and without a telescope!

1,058 Hours on the Andromeda Galaxy

September 2023 - March 2024

After the 255-hour image on the Whirlpool Galaxy released in the Summer of 2023, we decided to collaborate with the Deep Sky Collective yet again to produce the most impressive and accurate picture of a deep sky object ever.

After 6 months of work, we are all very proud to share our Kilo-hour image of Messier 31.

The Andromeda Galaxy with a cooled OSC camera

The equipment used to capture Messier 31

It is now time to capture the Andromeda Galaxy with a cooled astronomy camera!

I went back to a Bortle 4 zone and used the QHY600C One-Shot-Color camera to image Messier 31. I spent two half-nights on it for a total exposure time of 6.5 hours. I spent the first half of the first night on the Pleiades, which I love, and the first half of the second night imaging various small clusters.

Below is the result! I do miss the diffraction spikes that I got when imaging this target with my Newtonian reflector, so I plan on revisiting this object with a reflector in the future.
