Guest Phillyo Posted July 23, 2015 Share Posted July 23, 2015 NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800-1000 parsec distant (2600-3200 light years), with the younger components aged no more than a few million years. The complex also includes one of the hottest stars discovered within 3260 LY of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45000 K and a luminosity ~100000 times that of the Sun. The star is one of the primary sources illuminating the nebula and shaping the complex's famed pillars of creation-type formations, the elephant trunks.M: Avalon Linear Fast ReverseT: WO Star71C: QSI583WSG + Lodestar X2 GuidingF: Astrodon 3nm HaOnly 6 x 1200s exposures before it stopped imaging for some reason, which is a shame.
