About this image

I also had the Sony A7s set up with an 85mm f/1.2 lens staring at the radiant. This was running video at 25fps, ISO60000 and it generates around 20GB/hr. It takes quite a while for my software to run through this to detect events but it has just finished the first batch and there were quite a few faint captures. The attached is a composite of activity over around 30 mins.
