M15 taken with 200 exposures of 2 seconds each. Among those, 121 hand-picked (some light but persistent winds blurred quite a few).




Picture was taken quite precipitously (focus not quite right, neither scope nor camera cooled down), after I saw a curious object cross the camera's FOV pretty slowly. No idea what it is (it was not visible with the naked eye) but I'd be curious to know! Below are the three first exposures, which include that object.
