Combination of 40 1-minute images with H-alpha, SII and OIII filters.
SBIG STL-1001E CCD. 5" f/5 refractor at prime focus.
IC 5068, is the brightest os several small patches of emission nebulae located just south of the Pelican Nebula. These are all part of the same nebulosity that pervades this region of Cygnus. In the image above, a portion of the Pelican nebula and the North America nebula are visible towards the top of the image.
The above image was processed using the H-alpha images as the red channel. This is the preferred palette of the European Southern Observatory. The HST observers prefer to use the SII images as the red channel since the SII line is at a slightly longer wavelength than the H-alpha line. This results in a more green-dominated image as shown below.
