Object: M12
Constellation:
Object data: Globular
RA/DE:
This is another A+ view. Breath-taking, fully resolved, non-classic very
large globular. Individuals are clearly
brighter and overlay a slightly rectangular central area of dense and
partially resolvable core. Unique variation in foreground members which form
a pattern vaguely resembling the constellation Hercules. Brighter, more
irregular foreground stars than nearby M10 which is similar in brightness,
but more classic and symetrical than M12.
I was having such luck at resolving these clusters at this aperture with the
binoviewer, that I didn't even bother to move to a single eyepiece on this one.
