The Horsehead and Flame Nebula in the constellation Orion is one of the most iconic targets in the night sky and one of the most easily recognisable due to its distinctive shape. It is incredibly difficult to see visually, partly due to the brightness of the star Alnitak (brightest and largest star in image), it requires a large telescope, very dark clear skies and a hydrogen beta filter to see and even then some people have difficulty seeing it, however, it is very easy to take pictures of and responds very well to long exposures with DSLRs or specialist CCD cameras with either LRGB or narrow band filters. This was taken with Ha, OIII and SII narrow band filters on my Televue NP127/FLI astrograph with a FLI Microline 814x camera with a total of 8 hours exposure time
