Late update, never quite get round to posting the last photos of a cruise. Photos taken 20th and 21st April. We called in briefly to King Edward Point (KEP, 'capital' of South Georgia) to pick someone up and give the doctor some supplies (some medicines, it wasn't just chocolate). Fantastic cloudscape (and demob silliness) that evening and then we stayed in the shelter of the fjord overnight. Still being on nightshift pattern meant I saw the stars and dawn as well:
The Southern Cross
Jupiter over a ridge as dawn broke:
And looking the other way
For those interested, the nighttime photographs were hand held, resting on a 'bean-bag' (actually my gloves shoved in my hat, luckily it was quite warm) on the side of the ship (it was also very calm) with shutter times of 0.5 to 1 seconds, ISO 800-1600.
