About this image

This project proved more trouble than it first appeared - on night 1 my camera cooler became disconnected from its power so I had to average out the sensor temps and shoot some custom darks in order to calibrate the those lights properly.

On night 2 it went smoother and everything worked better - both nights ended early due to clouds
On both nights I shot tri-band filter to help control light pollution
