Andromeda Galaxy M31
LRGB-image of the Andromeda galaxy (M31) captured with the SPA-1 telescope: a Takahashi FSQ-106ED refractor, situated in IC Astronomy Observatory, Spain.
The Andromeda galaxy, our Milky Way's closest neighbor, is the most distant object in the sky that you can see with your unaided eye, but only on a clear night from a location with a very dark sky. The galaxy is a beautiful spiral at “only” 2,5 million light-years away with a diameter of about 220,000 ly and an estimated one trillion stars.
Total exposure 60 minutes. LRGB 6:3:3:3 with subs of 240s each.
