M31 Andromeda Galaxy

Photo Information
The Andromeda Galaxy can be found within the constellation of Andromeda hence the name. However this galaxy lies far beyond the foreground stars of our own home Milkyway Galaxy, the foreground stars being no more than a few hundred to a few thousand light years distant while the Andromeda Galaxy lies almost 2.5 million light years away and is larger than our own Milkyway Galaxy...half as large again. Every galaxy including our own Milkway has a black hole at their centre, the Andromeda Galaxy it seems has two, our Milkyway Galaxy and the Andromeda Galaxy are on collision course and will merge together sometime in the distant future. In orbit around it are two small elliptical galaxies M32 and NGC205.

Totally incredible shot and very humbling to think how insignificant we are in the vastness of the universe

Very nicely done. Good to know that all we have to do is wait a while and we won't have to mess about with a telescope to photograph it.
You can see some of my photos here if you are so inclined

Thank you all for the very kind feedback ...much appreciated!

The K5 is a fine camera for astrophotography, the 5 min exposures were surprisingly low in noise at 800ISO considering all noise reduction was switched off.

That's most impressive!

Beautifully done!
Whilst my scope/camera aren't quite as good as yours, with a lot of effort I ought to be able to capture something approaching this eventually, so I MUST give it another go soon!
Andromeda has always been something I've wanted to photograph. I'd need to do the dark field subtractions, find clearer skies, and improve my tracking considerably to get anywhere near this. Hopefully your shot will be the inspiration I need while the sky is still dark enough before my bedtime.
