| The Andromeda Galaxy is a spiral galaxy approximately 2.5 million light-years from Earth in the Andromeda constellation. Also known as Messier 31, M31, or NGC 224, it is often referred to as the Great Andromeda Nebula in older texts. (Wikipedia) |
This stunning image was taken by astronomer
Bob Anderson from his home in Southern England. Remarkably, this was Bob's first attempt at imaging M31, here are the details:
'Scope: TEC 140
Mount: ASA DDM60 Pro mount - an awesome bit of kit as even the 1,500 second subs were unguided!
Camera: FLI ML16803
Subs: 5 x 1,000 seconds using each of Astrodon Tru-Balance RGB filters plus 10 x 1,500 seconds using an Astrodon 3nm Ha filter
Software: PixInsight and Photoshop CS6
