Thought I would post an application of your Focus aid program here. If you inspect the attached photo carefully you can see that although by eye this looks focussed with the Bahtinov mask, in reality its ALMOST there but just off a tiny amount. This could be critical if you are dealing with a focal reducer which has a critical depth of focus such that if you are just outside of it one side or corner of your image will have odd stars.
Great application Al.
