                               Time: 14x20 min ( 4 hours) each for Ha, SII, OIII: total 12 hrs                           
                               Processing:  CCD Stack and PhotoShop CS/3
Image Information:  IC 1805 is the designation of a young star cluster and the emission nebula surrounding it.  The Heart Nebula (IC 1805) and Soul Nebula (IC 1848) are in close proximity in Cassiopia.  .  
Processing Comments:  The Narrow Band Image was produced using the Hubble Palette (SII, Ha, OIII). The resulting NB image was then overlayed in PS CS/e with another weak Ha layer, enhancing the nebulosity.  Further processing such as data stretching, High Pass Filter and Kodac Digital Gem in PS CS/3.
