Sony A7r nightscape ISO6400 30 second mosaic
6 months ago

Here is a recent mosaic I took of the night sky in remote NSW Australia.

Sony A7r, Nikon 14-24mm F2.8 ED at F2.8, ISO6400 and 30 seconds, auto white balance, long exposure noise reduction on, vivid, RAW, manual focus using magnifed view.

8 images. The colour in the night sky is correct - its called airglow which is oxygen atoms that have been energised by radiation that emit at night. The magenta comes from Sodium atoms I am pretty sure. The green is the oxygen. It is often seen at my dark site which has almost zero light pollution.
