North American and Pelican Nebula: Narrowband Image
From the Wiki Article: The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to Deneb (the tail of the swan and its brightest star). The remarkable shape of the emission nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico.
Check out my close-up RGB/Narrowband blend of the Pelican Nebula here. Other narrowband pictures with this combination, and more info, are at this link. Other astronomy pictures from the Fall 2011 trip are here.
Processing Details: Image Details: 6.25 hours total exposure, consisting of 39*5 Ha frames and 36*5 O3 frames with the SBIG ST-8300m (monochrome) CCD camera with the FW8-8300 filter wheel, Astrodon narrowband 36mm filters, and the Takahashi FSQ-85 telescope with reducer, AP 900GTO mount. The Ha frames compose the red channel, with the O3 frames making the blue and green channels, followed by subjective adjustments in Photoshop CS5. Star shrinking using Noel Carboni's actions.
