DescriptionThis was one TOUGH subject. Very large and diffuse, in truth a purely photographic nebula, and for modified cameras ideally.
My unmodded Canon 30D had fits with this thing, even with a whopping 3.5 hours of integration time. I have to get a modified camera soon.
More than 6 times the diameter of the full moon, IC 1396 is one of the largest emission nebula in the sky. The bright central star cluster (also designated IC1396) actually interferece with the view of nebulosity. The whole area is criss-crossed with dark nebulae - some of Barnard's are marked in the illustration below. There is also prominent nebula Van den Bergh 142 (the Elephant Trunk) just West of the central star cluster.
