Notice the red color and the fact that you can see tiny bright white stars right next to the edges of the moon on all sides. Usually, the moon would be too bright to let you see those stars.
Geoff, what are the short white lines at left, top left, right and bottom right? Stars that moved while you were taking a photo with slow shutter speed? Other stars (further from Earth?) didn't move during that time. And why are all 3 such lines angled in the same direction? Wouldn't 4 random stars have been going different directions? Or based on the rotation of the Earth or accidental motion of the camera? But then, why are the other stars such crisp dots?
Also, what is the tiny red dot at bottom right?
Specs: 300 mm zoom lens on a micro four thirds camera giving a 35 mm equivalent of 600 mm. Not a telescope. Camera? Shutter speed?
