The Pelican & Partial North American Nebula Area
This is an image of part of the North American Nebula, NGC 7000 & the Pelican Nebula, IC 5070 in the constellation of Cygnus.
It is very early in the season to image this area as it is low down in our NE horizon here. However, I thought I would have a bash in the latter stages of my imaging session on another object.
This is a straight RGB image of the nebulae using only a (very necessary!!) light pollution filter. They are both strong emission nebulae. The red colour is due to the Hydrogen Alpha emission line.
The resultant strong contortions of the gas give the Pelican nebula its name, as it looks rather like the head of a Pelican (r). It lies at a distance of around 1,800 light-years. The blue star near the "beak" is 57 Cygni, around 530 light-years from us. So much closer than the surrounding nebulae.
The North American Nebula (only partly shown here at left) is part of the same interstellar cloud of ionized gas as the Pelican and is separated from it by darker dust.
Imaged with an Askar 71mm refractor and a ZWO 2600MC camera. Exposure was just over 4 hours, lights being calibrated with temp. matched darks, flats and dark flats.
Thanks for looking!
