IC 1340 is part of the Veil Nebula, a supernova remnant in constellation Cygnus at distance of about 1470 light years. This is one of the more luminous areas in this SNR. Image is in colors emitted by ionized Hydrogen and Oxygen. The shock front formed by the material ejected from giant explosion, the super nova, can be seen in this image. Technical details: Processing work flow: Image acquisition, MaxiDL v5.07. Stacked and calibrated in CCDStack2. Levels, curves and color combine in PS CS3. Optics, Meade LX200 GPS 12" @ f5 Camera, QHY9 Guiding, SXV-AO, an active optics unit, and Lodestar guide camera Image Scale, ~0,8 arc-seconds/pixel 16 x 1200s exposures for H-alpha emission = 5h 20min. 12 x 1200s exposures for O-III, emission of ionized oxygen = 4h
