Description

Object: NGC7000 & IC5070 or the North American and Pelican Nebulae HST - 2018

North American Nebula (NGC7000): A hydrogen and dust cloud located in the constellation Cygnus which you can see rising in the east in summer to fall. Cygnus is sometimes called the Northern Cross and has the very bright star Deneb as the head of the cross. (Deneb, Vega and Altair make up the Summer Triangle). NCG7000 vaguely resembles the outline of the North American continent.

IC5070 or the Pelican Nebula is an H II region located near the North America Nebula in the constellation of Cygnus. The gaseous clouds of this emission nebula resemble a pelican, giving rise to its name.

This photo was done using the HST or Hubble Space Telescope Palette (sometimes called SHO: SII = red, Ha= green, OII = blue) which is accomplished by combining sub frames using three narrowband filters that capture light produced by glowing hydrogen (Ha), oxygen (OIII) and sulfur (SII) present in the nebula. Green is assigned to hydrogen, blue to oxygen and red to the sulfur.

Note: this is the first photo I have done with the KAF-16200 based, Starlight Xpress SX-46, so I picked low hanging fruit! This also allowed me to get both nebulae into the same shot without using a mosaic or a very wide angle camera lens.
