IC410, the Tadpole nebula

IC410, the Tadpole Nebula (nebulosa de los renacuajos). New

IC 410 or the Tadpole  nebula (nebulosa de Los Renajuajos) is an emission nebula located in Auriga. The light of very energetic stars in the star cluster NGC 1893 (to the left of the dark molecular cloud in the center of the image) ionizes the interstellar gas (mainly Hydrogen but also other elements such as Oxygen ans Sulphur) which thus emits light at specific wavelengths, being the responsible of the nebula glow .  To obtain this image, several narrowband filters were employed to isolate the Sulphur II, Hydrogen alpha and Oxygen III emission lines, represented here as Red, Green and Blue, respectively. The Tadpoles (Renacuajos)  can be seen  on the upper left quadrant of the image, which are composed of dust and gas, their tails are caused by the radiation pressure and solar wind from the stars of NGC 1893.
