I am not sure if it is my connection to astrobin, but none of the images I have posted the last or so fail due to a internal server error from nova.astrometry.net, is anyone else running into this issue.
I spent most of the early evening and into the morning hours imaging once again SH2-177. I used my L-Ultimate filter and I like the results in natural color. I processed / post-processed this image in SIRIL with the exception of BlurXterminator and NoiseXterminator.
Sharpless2-171 is part of a bigger nebula, NGC 7822, in Cepheus. It is an emission nebula with elephant trunks, or pillars, carved by stellar winds of the hot bright stars within the nebula. NGC7822 star-forming complex in the constellation Cepheus is located about 3,000 light-years away from us. It contains Berkeley 59 star open cluster (in the upper right part of the nebulosity) that contains one of the hottest stars discovered within that distance. This is BD+66 1673 star – an eclipsing binary system containing an O5V type star with a surface temperature of about 45,000 K and a luminosity of about 100,000 times that of the Sun.
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 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, the
elephant trunks.
