| NGC7000 North American Nebula | ||||||||
 |
||||||||
| The North American Nebula is an incomprehensibly large complex of Hydrogen Alpha gas within our own Milky way. I read recently that this complex is approximately 6,000,000,000,000 (Trillion) miles wide! The nebula is named such because of its resemblence to North America, particularly in the Gulf of Mexico area. To its right is the aptly named Pelican nebula, do you see him there? Under very clear dark skies this nebula is easily visible to the naked eye. To find it, locate the brightest star in Cygnus (Deneb) which is the tip of the northern cross or the eye of Cygnus the swan, draw an imaginary line from Vega to deneb and go about two fingers at arms length and there it is, that bright patch that looks like a cloud is this nebula. Technical Data Scope: 400mm lens & OM-1 camera Guiding: ST4 Film: Supra 400 for RGB and hypered tech pan for luminance Composition: Two 60 minute RGB shots layered and flattened in PS, luminance layered with a 90 minute tech pan shot taken with a lumicon hydrogen alpha shot. I used Rob Gendler's LLRGB and HA-RRGB itteration method to combine these shots and bring out the contrast. |
