IC 1396 |

IC 1396 is a large emission nebula in the
constellation of Cepheus (The King). This object is 3 degrees,
or 6 full moons, wide! Since it is estimated to be 3,000 light
years away, that makes this cloud hundreds of light-years wide!
The huge nebulosity is very faint, but the star clusters
associated with it are pretty bright and can be seen with the
naked eye in a dark site far from big cities. This object
contains not just huge clouds of glowing ionized gases, but also
dark dust clouds sculpted into interesting comet-like shapes by
the intense stellar winds and radiation from the stars embedded
within. IC 1396 first came to my attention as a large object in an inexpensive version of TheSky that came with one of my telescope purchases back in 2000. I was intrigued by the enormity of this object and gave my 8" GOTO scope the command to aim at the target. As would be expected, I saw no sign of its nebulosity, but I did see some of the star clusters associated with it. |
