Djaffar s'est amusé à combiner le H-alpha et le RGB pour le couple #M81 et #M82
Setup : le SW200/800, Caméra couleur ASI2600MC. Les brutes : 75 x 300s en Lpro et 45 x 600s en L-Extrem

Some more Aurora photos - May 28th, 2017, and I just happened to have the tracking mount up and running when an aurora outbreak kicked in. A wonderful experience. This was at Pine Bay Cottages along the St. Lawrence River in upstate NY.

This was a really special night out under the stars and high energy atmosphere.

45 - 60 second exposures.
