I had a little go at NGC300 last night - messed up the run as I left the camera in JPEG small/fine after focusing...but I did get this odd frame in the middle of the run, the exposure is at 20:07-20:10 last night, it has a faint trail through it - do not think it is an aircraft - Iridium flare ? Could not see anything on Heavens above that would match? High level a/c perhaps? Satellite? But those would leave a series of flashes or a trail...image is straight of the camera and the previous and subsequent images show nothing odd as you would expect?
