Pelican Nebula (IC5070) taken from Leeds UK by amateur astro-photographer urmymuse. The Pelican Nebula (also known as IC 5070 [1]) is an H II region associated with the North America Nebula in the constellation Cygnus. The gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name. [1]
In his study of nebulae on the Palomar Sky Survey plates in 1959, American astronomer Stewart Sharpless realised that the North America Nebula is part of the same interstellar cloud of ionized hydrogen (H II region) as the Pelican Nebula, separated by a dark band of dust, and listed the two nebulae together in his second list of 313 bright ...
The nebula is known as S 142 in the 1959 Sharpless catalog (Sh2-142). [2] It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. The NGC 7380 complex is located at a distance of approximately 8.5 kilolight-years from the Sun , in the Perseus Arm of the Milky Way .

Sh 2-308, also designated as Sharpless 308, RCW 11, or LBN 1052, [1] and commonly known as the Dolphin-Head Nebula, is an H II region located near the center of the constellation Canis Major, composed of ionised hydrogen. [2] It is about 8 degrees south of Sirius, the brightest star in the night sky.
NGC 6357 is a diffuse nebula near NGC 6334 in the constellation Scorpius.The nebula contains many proto-stars shielded by dark discs of gas, and young stars wrapped in expanding "cocoons" or expanding gases surrounding these small stars.
After earning his bachelor's degree, Andreo moved to the San Francisco Bay Area, where he worked for Netscape Communications and eBay as lead software engineer. [2] In 2008, he started exploring astrophotography as a hobby and developed a personal style defined by deep wide field images that has led to international recognition and a meaningful influence on the discipline.
