Image Infornmation: The original
Narrow Band of this emission nebula was published in June. With my camera in for repairs I got a chance to assemble
the LRGB data, and (next image) a composite LRGB/NB image. IC 1318 is a large emission nebula surrounding
Sadr, within Cygnus the Swan. The northern section, also known as the Butterfly nebula (IC 1318b) has a dark
nebulosity which bisects it (this image was taken near this region). IC 1318b It is primarily made up of ionized
hydrogen but there is a significant SII component. The nebula is believed to be about 4000 light years distant.
This image, spanning about about 15 arc-min, and located near the dark nebulosity, is just a small part of this large, 1.5
degree, nebula (IC 1318a, b and c).
Additional Comments: Image processing with CCDStack, producing an RGB image which was later combined with a Luminance image
in Photoshop CS/3. Further data stretching, high pass filtering and background smoothing was performed in Adobe
