Comments
This is the first time I have used a circularly symmetric mask based on a spun blur of the original planet image to remove the edge rind artefact that so affects Mercury images. Seemed to work quite well- sharpening up the edge, dropping the severity of the artefact considerably and allowing detail at the edge of the planet to come through nicely.
