Rutland Water star trail take 2

Ok, not strictly a new image today. This is the result of me trying to learn how to take the noise out of the image in photoshop, then going back to iPhoto to make the final adjustments on a good screen - rather than my TV (as is currently plugged into the PC).

There's a definite loss of noise, but I think it may have lost one or two stars as well. I think there is still room for improvement but it's definitely a start :)
