A very nice picture. What ISO setting did you use, and is there a reason why you used such a difference between the exposure settings?

Hi Jan, I used an exposure of 30” at f5.6 for the stars (at 800 ASA) and 5” at f5.6 for the moon (at 400 ASA). I pasted the 30” exp onto the 5” one in Pshop and used the erase tool to remove the pixels of the overexposed moon image.

Quite a complicated procedure David, but a nice result.
