- Description: Nebulosity around Gamma Cygnus, known collectively as IC1318. This is the
first complete narrow-band image with my smallest refractor, the William Optics Redcat 51 LX.
(2nd version) Gamma is the center of the Northern Cross in the summer sky. The star cluster in the
upper right is NGC6910, 50 stars, 7 arc minutes across. Magnitude 7.4. For this image I mapped sulphur
to red, hydrogen to green and oxygen to blue using the Foraxx palette.
