People often don’t realise how hard to see the horsehead nebula is. It is quite a faint nebula located in the constellation of Orion, faint enough that you need a reasonably large amateur telescope (for example 15″ aperture reflector such as a dobsonian) and dark skies to visually see it.
Photographically the Horsehead is well known and captured by amateur astronomers. It sits along side one of the brighter stars in the constellation of Orion, Alnitak, which is one of the three bright stars making up the Belt of Orion. The Flame Nebula is also located adjacent to Alnitak.
