Description

NGC7000

Constellation: Cygnus
Right ascension: 20h 59m 17.1s
Declination: +44° 31′ 44”
Apparent size: 120 x 100 arc minutes
Apparent magnitude: 4
Distance: 1,600 light years

NGC7000, the 'North America Nebula' is a large emission nebula located in the vicinity of Deneb, the brightest star in Cygnus. The nebula is famous for its shape, which bears a striking resemblance to that of the North America continent. It occupies an area of 120 by 100 arc minutes and has a visual magnitude of 4. It lies at an approximate distance of 1,600 light years from Earth. It is listed as NGC 7000 in the New General Catalogue. The North America Nebula is part of the same H II region as its smaller neighbour, the Pelican (IC 5070). The two nebulae are separated by a molecular cloud of dark obscuring dust. They are both located in the Orion Arm of the Milky Way.
Despite having a large apparent size, more than four times that of the full Moon, and a visual magnitude that puts it in the visible range, the North America Nebula usually cannot be seen without binoculars because it has a low surface brightness. It requires exceptionally good observing conditions to be seen with the unaided eye. In clear, dark skies it appears as a portion of the Milky Way. In binoculars and small telescopes it appears as a fuzzy patch of light. 
The portion of the nebula that exhibits the most concentrated star formation is called the Cygnus Wall. It spans about 20 light years and appears as a W-shaped ridge in the part of the nebula that resembles Mexico and Central America.

The dark nebula that lies in front the North America Nebula and blocks its light along the “East Coast” is known as LDN 935.The open star clusters Collinder 428 and NGC 6997 appear embedded within the nebula, but are not really related to it. NGC 6997 can be seen in the direction of the “Great Lakes” area, but in fact lies hundreds of light years beyond the nebula. Collinder 428, visible at the eastern edge of the nebula, may not be a cluster at all, but just a window visible in the dark cloud.

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

THE IMAGE - A QUICK GRAB!...

Opportunity shot taken in Ha and 180 degrees in opposition to rising Full Moon.
The amount of Hydrogen and Dust in this Nebula is mind-blowing, the familiar 'Pelican' and 'California' areas are almost obscured at this wavelength...
Taken on the Redcat 51 using an APS-C Sensor, 90 minutes integration and using the awesome Optolong 3nm Narrowband Ha Filter...
I’m still having issues with the optics of my Redcat, the stars are not great on a good portion of the image circle, definitely not sensor tilt and I’m currently awaiting answers/solutions from William Optics…
After about 2 hours the rising Moon turned the whole sky into a bright pastel blue haze and I had to stop imaging...
Was also a bitterly cold sub-zero night but, in the end, worth the effort...
