SH2-171 and a rare jewel

Description

This is my first light image using the QHY128C a 24 Megapixel full frame Cooled CMOS camera. The image was captured from GrandMesaObservatory.com in Purdy Mesa, Western Colorado with a Takahashi E-180 Astrograph. The are two TAK E-180’s that are configured as dual scopes on one mount, or bino’s.

I am very pleased with the performance of the QHY128C and I grossly underestimated the depth and detail in the final image.

Encompassing the emission region designated Sharpless 171 is the star forming complex NGC7822 a spectacular example of a stellar nursery. The emission nebula shines as a result of the ionizing radiation from one of the hottest stars known; BD+66, which has a luminosity 100,000 times that of our sun. Curiously enough, BD+66 is also an eclipsing binary, which means that it is actually two stars in orbiting each other and are aligned in such a way that one star occasionally eclipses the other from our perspective, is a very young star forming region; no more than a few million years old. It will continue birthing new stars for several million more years until the radiation from the new stars blows away the last remnants of hydrogen gas, leaving behind a small cluster of young bright stars.
