Median stacked as at least 8 images had satellites or meteors on.

I did write some notes on this but they appear to have vanished.

Before taking it I did try images with and without x2 binning. Was impressed by how little difference it made to the strengths of detections of stars. The background sky certainly dominates the frame stats in the UK. Nice to see though that in a 60s frame stars of magnitude 17.5 were detected. So with stacking this images should be rather deeper.

Dithering was worth doing.
