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 Photoshop CS/3.
