DescriptionIC 1318 region. The bright star is gamma Cyg (Sadr) and the dark molecular cloud is LDN 899. The open cluster M29 is on the bottom right and NGC 6910 is on the top left. This is a "true color" narrow band filter image made according to the article in the December 2011 issue of Sky and Telescope, p. 70. Although less obvious than with the Hubble palette of color, the presence of OIII regions mixed with Ha and SII in the right bottom corner is clearly visible.
