HI Roger, that's a nice Venus image. But you've got some horrible colour shift there due to the object being low on the horizon.
Open up the channels tab in photoshop and click thru the red/green/blue channels and use the MOVE tool to re-align them. It will look heaps better! I'm guessing it will need a shift of 2 pixels right for the red and 2 pixels left for the blue (or there abouts).
Great image.
