IC 1795 or the Fishhead nebula. by Lars Zetterlund Via Flickr: IC 1795, also nicknamed the Fishhead nebula, is an emission nebula in Cassiopeia. This is a bicolor image with a synthetic green from 10h45 min of OIII and 9h20 min of Ha. This image could benefit from SII as well, but I decided that I had already spent enough time on it. Imaged with an Atik 460 through a C14 with 0.63 reducer riding on a Paramount MX.
