The North America and Pelican Nebula

 

The North America and Pelican Nebula in the Constellation Cygnus the Swan. Composite image of 1.5 hours of data captured with the Jodrell Plank Observatory astromodded Canon 200d DSLR and the unmodded Canon 600d DSLR cameras 
 A Samyang 135mm lens was used on both cameras which were set to capture
one minute exposures at ISO800. The caneras were on a Star Adventurer
equatorial mount. The images from the two cameras were combined using
RegiStar software and processed using; Affinity Photo, FitsWork4, Topaz Denoise AI and GradientXterminator. Plate solving by Astrometry. net. Image Credits; Pip Stakkert and Astrometry net.

"Discovered by William Herschel in 1786, the huge North American (NGC 7000, left) and the smaller, dimmer Pelican (IC 5067/5070, right) Nebulae in Cygnus are  estimated to be 2590 light years distant (Gaia). The intricate, eastern edge of Mexico and Central America is known as the Cygnus Wall, a region of hot gas, dust and young stars. The Gulf of Mexico is a visual effect created by dark nebulosity or cold dust. Seven foreground stars in the 'Gulf'  form an asterism called "Little Orion." Do you see it? It is more obvious in the image below.

The North America Nebula is estimated to stretch 90 light years north to south and is part of a much larger cloud of ionised hydrogen gas some 140 light years across. Dark nebulae punctuate the region creating the individual clouds of glowing gas.. The gas is ionised by very hot and massive stars hidden within the cold dark nebula of the 'Gulf of Mexico'. In our image the Blue Giant star Deneb and the spectroscopic binary star (colour yellow) Xi Cygnus dominate". - Kurt Thrust current Director of the Jodrell Plank Observatory.
