Last night? Where did you go Ryan? It was cloudy in Melbourne last night. I wanted to go somewhere but didn't expect anywhere that wasn't too far out of Melbourne would have been clear.
Good on you for making the effort and a fine result you achieved. I've got one of those CLS CCD filters and find them difficult to colour correct in post processing, I notice your result looks a bit monochrome. Perhaps you could lift the saturation a little to gain a bit more colour but you're right, it does look good in black and white as well.
