Another one from the first night with my triple rig. ISO1600. The f/4 lens was accidentally set by the camera (after a battery shift) to f/5 causing the spikes around the major stars. Sorry about that. No idea what caused (natural or artificial) the green flare near the centre of the image.

Had another night where I run the lens at full opening (f/4) and could use the data to save the stars from those iris spikes
