Double Cluster

About a year ago I published a photo of the Double Cluster in Perseus (NGC 869 and NGC 884), two stars clusters in constellation Perseus (see here: flic.kr/p/2mJWPjw). This year I photographed the same area but with an hydrogen filter, in order to reveal the faint hydrogen clouds in this field of view, here seen as the red clouds.

 

Photographing the invisible is an intrinsic trait of astrophotography - deeply amazing but also a responsibility to the photographer - which usually reminds me of Saint-Exupéry’s Little Prince famous quote the “anything essential is invisible to the eyes”.

 

I hope you enjoy.
