Every now and then I point my 600 f4 up at night and see what I can capture. This is a shot of a nebula in Orion that is slightly visible to the naked eye when the seeing is good.
Camera: EOS 1DsMKiii (used the timer to trip the shutter because I didn't feel like dragging out the cable release.)
Lens: 600 f4L IS
Mounted on a tripod. Wimberly head.
Manual Mode. AWB. RAW format
ISO 1600
2s@ f4
At 2s there is some slight streaking (star trails). I elected to accept that over dealing with the noise at ISO 3200.
