36 hour Crescent Moon

Session name: 20080506.1915


Another image of the recent crescent Moon, age 35h 55m, taken handheld through 7x50 binoculars. The vertical line doesn't look like a good thing.
How does one clean up the noise? I use gimp for cropping but haven't done any type of clean up.
Directions.
The Moon sets toward the 5:00~5:30 direction and is approximately Lunar East. Lunar North is near the cusp on the right side.
