The Rosette Nebula
Taken by Rhys Owen, with a DSLR Canon 600, newly acquired and newly modified too, he obviously means business. The forecast was good, clear all night, but he must have had an inside source that told him it wasn't going to hold. He rushed in, set it all up and spent long enough focusing, and it takes some time to do it if you're using trial and error rather than software to do it.
A short couple of 30 sec shots to test and then on with a series of 20x60 sec frames at ISO800, followed by 4x60sec darks. He sat and ran them without any software control, counting them as they went. All I had to do was find the nebula and set the telescope to point at it and balance the mount suitably.
Almost as soon as he's done, the clouds started to roll in. He must have known.
The frames were stacked in Deep Sky Stacker and post processed in Photoshop to produce the final result.
