Processing Images – M31 Andromeda Galaxy (Part 2 of 3)

When photographed with a large telescope, the Andromeda Galaxy can appear to be six times wider than our Moon. You can see this galaxy with the naked eye as a sort of smudge in the sky. But to see it without a telescope you would need to look for it on a moonless night. When looking at it with the naked eye, the light you will see is from the center of the galaxy and you will not see any of the spiral structures.

We processed the 3 exposures from the last post and again we had to decide what details to bring out. We finally decided to focus on the central area of the Andromeda and try and bring out details not evident in the exposures.

The nucleus of Andromeda is a dense cluster of stars which you can make out in the picture below…… and of course as is the case with the majority of galaxies there is a black hole in the very centre of this mass of light.

Now we are not finished with the Andromeda Galaxy yet. We have one more exposure left to process and it will be interesting to see  if it has any impact on the overall result.
