The Caldwell Objects

ightest spiral arm(s) to the north, which arc(s)
toward the west. A roughly 10.5-magni-tude star
on the galaxy's northwestern edge could fool a
supernova hunter, so beware! At high power two
spiral arms (or groupings of spiral arms) are seen
with difficulty: the one mentioned above and
another, fainter one to the south, which curves to
the east. The brightest ΗII regions seem to pulse
in and out of view to the east and southeast.
After observ-
93 & 101
ing NGC 6744 with a 12-inch telescope, Ernst
Hartung described it "as a large irregularly
elliptical faintly luminous haze more than 5'
across with some faint stars involved. The centre
about 30" wide is bright and looks granular . . . In
good conditions [a 4-inch telescope] shows the
nebula plainly." Others have clearly resolved the
galaxy's spiral arms with a 10-inch instrument.
Still others have commented on a greenish hue.
Has anyone else seen this?
