Image Infornmation: 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 a Narrow Band image using the Hubble Palatte. The
Narrow Band image was created by equally weighting the SII, Ha and OIII images and assembling in CCDStack. Further data
stretching, high pass filtering and background smoothing was performed with Adobe Photoshop CS/3.
