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 3000 light years distant (ly), with the younger components aged no more than a few million years. The complex also includes one of the hottest stars discovered within 3000 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 45,000 K and a luminosity about 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 (Source: Wikipedia).
I've included two images of this relatively small nebula. The images were created from 76 4 minute exposures (5 hours total exposure) using a special filter. The red image is in a "natural" color palette that shows the ionized hydrogen. The other image was created using a "faux" Hubble palette to show the Oxygen III (blue) and Sulfur II (yellow-orange).
Over the next many years I plan to shoot as many targets I can within the reach of my 4 telescopes that I can configure to have the following focal lengths: 250, 390, 440, 925, 1440 and 2030-mm.
Thanks for viewing and you comments are always welcomed.
