M51 Whirlpool Galaxy

A nice clear night last night until around 12:30 when clouds rolled in. Managed to get this image of the lovely M51 Whirlpool galaxy. It lies around 23 million light years away and it is interacting with a smaller galaxy (yellow~ish bulge to the left). Three supernova (star explosions) have been detected in this galaxy since 1994. There's more detail here but I think I'm pushing things with an 80mm scope.
