The Flying Bat (SH2_120) and the Squid (Ou4) Nebulae

This is an image of the Flying Bat Nebula (SH2_129) and the Squid Nebula (Ou4). These nebulae lie about 2,300 light years away in the constellation Cepheus. The blue-green Squid nebula is the result of doubly ionized oxygen atoms while the reddish Flying bat nebula is the result of hydrogen emissions.
