Airglow, gravity waves and why the deepest night is not quite as deeply dark as it first may seem...


There are lots of amazing wonders to be discovered in the night sky. Some are well known and highly sought after - such as the aurora. Others are a little less known - but no less beautiful to photograph.

Find out about airglow in this free mini eBook - what it is and what to look out for if you think you've spotted it in the dark skies above.

With photographs and diagrams, the text tells the story of the two times I've photographed it so far and also pulls back the curtain a bit on some of the fascinating science behind this natural wonder.

I am offering this eBook free. But, if you think it's useful and would like to support me in producing more content like this in the future, you can make a 'Pay what you like' contribution below!
