North America & Pelican Nebulaes

The North America & the Pelican Nebulaes.

 

The North America Nebula (NGC 7000) is an emission nebula found in the Cygnus constellation, glowing due to the ionisation of interstellar gas caused by radiation being emitted by hot, young stars.

To the right of the North America Nebula, is a less luminous nebula nicknamed the Pelican Nebula (IC 5070). The two emission nebulaes measure about 50 light-years across, are located about 1500 light-years away from us.

The North America Nebula was discovered by William Herschel in October 1786. It was first photographed by Max Wolf in December 1890.

 

At first I was supposed to shoot only the North America Nebula. On the second day, the sky was clear, so I decided to shoot the Pelican too with the goal to make a mosaic.

As the nights are short, I just have +/- 3 hours of total exposure for each panel.

 

Now, the only thing to do is waiting for clear skies !

 

This picture was shoot during a waxing gibbous moon.
