LMC Blue Filaments (Dragon unbound!)


This sketch covers a bright field 2 deg. N of LMC centre. The fov is 3 full moons wide and 4 high. It's a big field! The two filaments alpha-alpha and beta-beta are, apparently, anonymous. They are very blue in H-beta. It's presumed they are distorted galactic blue-knots or arms of mainly OB stars. The named features are listed l.h.s. Why did the filaments take this strange shape? They are visible in small binoculars. The 'Dragon's Head' is the only thing with a common (and appropriate) name. The whole looks like an Oriental dragon!
