Description

I originally tried capturing NGC 7822 in the hubble palette when I first got into narrowband. It is not the best DSO to start out on in narrowband, as it is really faint; especially in OIII and SII. This is a bicolor version in Ha and OIII. I am capturing more SII still and will do a hubble palette version. I had to really massage the OIII data even after capturing more OIII this year and combing it with last year's data. This is a combination of data taken last year with my old 102mm and this year with my current 152mm triplet.

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 pc distant with the younger components aged no more than a few million years. The complex also includes one of the hottest stars discovered within 1 kpc 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 ~100,000 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.
