Description

First attempt at such a long integration, still struggling with calibration of the 1600pro. Bortle 5 skies over a few clear(ish) nights between Feb and April 2019. I'm sure better results can be got with the data but still very much learning!

Pushing the data as far as I can I've managed to extract some IFN. Obviously needs a lot more exposure for better definition but amazed it could be seen at all.
