Was this supposed to look so good? Once in awhile I stumble
upon a nebula that is much better than I had expected. The blue
flash nebula is a bluish tinted round planetary that sits in a rich
field of stars. As soon as I applied magnification.. it's goblin-like
face became apparent, particularly with averted vision. It's central
star becomes very visible at 320x, and above, and looks like a nose.
Two symettrical wide triangles pointing in towards the central
star appeared o form "eyes" , particularly since they were darker
on the top 1/2 of each (south was up) Reminiscent of the owl nebula.
View through the binoviewer was similar, but the splitting of the
beam robbed a bit of color from the object, otherwise much the
same.
thanks!
