Perseid meteor with LCD shutter enlargement

About this image

Enlargement of meteor trail. Shows nicely the rapid chopping action. The image also shows the "infill" of continuous emission from the forbidden green oxygen line at 557.7nm. Each segment is 12.5ms long there is also some continuous white light emission seen between the main segments. I'm unsure whether this is genuine or "leakage" through the LCD shutter as the meteor was probably very bright to record this well. More examples are needed! ;-)
