shooting the moon

ive tried this many times
im lucky cause i can see the moon from my bedroom window everytime she shows up
n this is the best result i can produce for the moment
shot using the 100-300 usm .. ofcourse, at 300mm
no tripod, just handheld
chromatique/colour aberation is obvious - gotta to touch up a bit using photoshop to take it away
may be i should find a telescope to get better image :)
