About this image

Close to the equinox so geostationary satellites are passing through the Earth's shadow (middle).  I calculate the shadow to be 17 degrees across.  This is 734 images captured over a 2 hour period stacked.  Biggest challenge was removing frames with aircraft in them, there were many.
