This is a re-process of messier 13 which i photographed a couple of months back. I thought i could improve on it and managed to bring back some star colour and a bit more data.
Nikon D3300 + SW 130p (Alt-Az mount) with x2 Barlow
70x15s Exposures at ISO 1600
Stacked in DSS, processed in Photoshop
(I think focus was a little off the night i captured this)
This is a foculation tank. It is used to treat poo. Basically everything on the ship is reduced, as much as possible, to constituent components and either recycled or burned. Ashes are taken ashore and carefully controlled 'sludge' (left over food courtesy of greedy fat Americans who take more than they can eat) is released into the ocean. I have been assured that the ship is very environmentally friendly.
