I miss the battery grip! I got 74 minutes of exposure (ten exposures of 7 mins 40 seconds)
with a gap of one second between, before the battery died. This time I used JPEG. No problem. While the composition isn't my most elegant, i'm too tired to go out and do it again.
ISO 200, using 17-40L at 17mm. Noise is virtually non existent. I did a USM
of 115/2.4/4 and a color adjust. No need to change levels. I'm learning this camera
and I'm impressed.
