If I remember well the D40 has burst capability so that you can take a number of shots very quickly. I would use it if available. The trick is always to take the greatest number of shots in the shortest time available by the body you’re imaging. For the moon this is set by the speed of the advancing or retreating shadows more than anything else, which should be in the several minutes at least (shortest when the moon is closest to the sun and longest when it’s in opposiiton to the sun). The best way to use the shots you’ve taken is always to allow a program such as Iris or (alas) Registax to quality-filter, align and stack them up. Use the final stacked-up image to do all the contrast enhancements required.Andrea T.
