NGC7000_ Bi-Colour_StarLess_2-10-22

**STARLESS VERSION OF THE NORTH AMERICA NEBULA**

 

Well, managed to get this in one night. Conditions were not to bad but the moon was at 80% so I took the Ha first and the Oiii when the moon was lower. Took long than expected as the guide camera stopped working 3 times which required me to unplug and reconnect, need to look into that. Well, though the moon is on its way out so are the clear skies according to the weather forecast for the next two weeks so I guess no more imaging.

 

Object Description:-

This is NGC 7000 the North America Nebula. It is an emission Nebula in the constellation of Cygnus at a distance of approximate 1,600 - 1,800 ly with a visual mag of 4.0 and is made up mainly of ionized hydrogen. The brightest part is known as the Cygnus Wall which exhibits the most concentrated area of star formation. A band of interstellar gas between us and the nebula absorbs the light of the stars giving it this unique shape.
