Star trails.

4 hours of 15 second exposures cleverly blended in camera by the wonderful OM1 at 7mm & 320 ISO.
Had to stop when the very bright moon started to move into view.
Not sure what the green streak is yet. It might be a Geminid meteor or perhaps a Klingon ship??? Now believe the green streak is a lens flare caused by the nearby and very bright moon.
