Daniel, I would think 1/20 is a bit too slow for the Moon at a focal length of 510mm, and there will be blurring caused by the Moon moving in the sky. Another thing to bear in mind is air turbulence, which will affect the IQ in a random patterns; it's always advisable to take 3-5 photos at the same settings and then choose the sharpest one (which will be the one taken during a brief moment of calm air).

Yes, I had the same experience but wanted to get the full moon. But why exactly is this so (forgive me if I am asking the obvious) too much illumination??[/QUOTE]
