SX50 - Moon Shot - Advice appreciated

Recently purchased an SX-50. Tried a couple of shots of the Full Moon last week.

Any thoughts on how this image can be improved ? (prefer to shoot RAW than JPEG) - No post processing done (apart from converting from RAW to JPEG in LR4.3)

ISO 80, Manual Mode, RAW, 1200mm, 1/50, 6.5 / Tripod was used
