The Horsehead Nebula (B33) is a small dark nebula in the constellation Orion. It is perhaps the most recognizable nebula because of its resemblance to a horse’s head. The Nebula is located just to the south of Alnitak, the easternmost star of Orion’s Belt.
IC 434 is an active star forming H II region located at a distance of approx. 1,260 ly from the Sun. This is an H II region that is being ionized by ultraviolet radiation from the nearby Sigma Orionis multi-star system. The Horsehead Nebula is a dark nebula that is silhouetted against the diffuse background of IC 434.
The photograph consists of 300 180s subs. They were acquired from my driveway using the APT session control software. I used a RC8 telescope and an ASI071MC Pro camera. The camera was riding an Eq6r pro german equatorial mount.
