Hydrogen alpha image of Messier 8
M8, an emission nebula, is found in the constellation Sagittarius. A significant portion of it's composition is hydrogen, which emitts light due to the excitation of the hydrogen atoms from radiation coming from the embedded stars in the nebula. A particular wavelenght of this emission, Ha, was imaged using a narrowband filter and assigned a red color (TeleVue 85 refractor; 0.8 reducer/fattener; SBIG ST-2000 CCD; 25 x 5 min lights; 30 darks; 41 flats).
