Yet another boring grey day with absolutely no chance of imaging. So to keep my hand in with the image processing I decided to have a go at the California nebula region using DSS2 data. I tell you how to process this data in my book “Making Beautiful Deep-Sky Images” and I have also written a tutorial article for Astronomy Now.
Luckily – the DSS2 data seems to be pretty good around the California nebula region (this is unfortunately not always the case).
