I actually remembered to go and take a photo of the full moon last night in the wee hours (about 4:30am.. don't ask).
The moon was fairly high in the sky and there was nothing around interesting to include in the photo, so I just zoomed in as close as I could and tried to capture as much detail in the moon. I also tried a couple of infra-red shots, and although I was suprised that I could get decent exposures and semi-decent shutter speeds (4sec), I couldn't get anything remotely sharp.. Caused by either the focus shift with IR, the difficulty in focusing on the moon in complete darkness through an IR filter, or the fact that even in 4 sec the moon will actually shift a little bit.
Anyway, this is a full crop of the best non-IR shot (contrast-enhanced). It is still a bit soft, but looks nice and sharp (but small) at 50%.
Lens: EF 70-200 f/4L USM @200mm with Olympus TC17 1.7x teleconverter.
Aperture: f/11, Shutter 1/100, ISO: 100
