Hi C101, when taking single exposure lunar images with a DSLR it is wise to
use the highest shutter speed possible, as mirror slap and shutter vibration
can slightly affect the sharpness of the image. As there is no depth of field to
worry about, and most lens aberrations are in the outer portion of the image
where there is nothing, there is nothing to be gained by using f/8. From
memory I used ISO 1000 and around 1/3200th sec at whatever aperture
gave the correct exposure, around f/3.5 or f/4 I think.
Pretty good image though, I've seen much worse.

P.S. The best images are obtained by using video and stacking the best frames.
