Actually no, it is not a merge of two photos! I don’t really know how I got the moon to show so sharply with 2.5 second exposure! As you can see in the attached crop, the moon isn’t really tack sharp at all, but the resized version is a lot more forgiving as far as sharpness is concerned. Probably the motion blur from the clouds contributes to the ‘optical illusion’ of sharpness also.
