Andromeda Galaxy

The Andromeda Galaxy (NGC 224 or M31) is located 2.3 million light years away. This is the closest spiral-type galaxy to our own Milky Way. The Magelanic Clouds are closer but they are irregular galaxies, i.e. not in a spiral type structures like us.

The stars visible in front of Andromeda are all foreground stars that are part of the Milky Way. It is not possible to see individual stars that form part of the Andromeda Galaxy. The small galaxy below Andromeda is NGC 221 or M32. There is also a small elliptical galaxy  above and to the left of the Andromeda core, this is NGC 205.

M31 4x3min 1200

This image is made up of 4 x 3 minute exposures and three dark frames. I used an iOptron SkyTracker to guide the camera and I used a Canon EFS 18-135mm lens at 135mm with 720 second exposure in total at f/5.6 and ISO-3200. Processing with DSS, CS2 and LR4.

    Hello, You stated a total of 720 seconds or 12 minutes for the M31 image. Is that 4 – 3 minute exposures stacked?
