Description

The longest integration time I've yet managed of any subject so far. It looks pretty wow to me, even though I had made a mistake and for the first part I had the camera accidentally set to 30 second lights instead of 120 seconds, and I had bumped the tripod twice. Woops. But all is well that ends well. Look at those colours!!!
