NGC 2298 Bennett 37 ESO366-SC022, GCL-11 RA 06:48:59 Dec -36°
00.3' Globular cluster |
Dunlop 578: "a pretty bright round
nebula, 3' or 4' diameter, moderately condensed to the centre. This is
resolvable into stars."
h: "B, R, gpmbM, 3', all resolved into
stars 14th mag. In the centre is a star 13th mag." On a second occassion he
called it "globular cluster, pB, R, gbM, 90 arcseconds, resolved into stars
14th mag." His third observation was recorded as "B, irregularly
round, gbM, 3', resolved into stars 14th..16th mag with stragglers, and some
large stars near." The final record reads: "globular cluster, pB,
irregularly round, gbM, 2.5', resolved into stars 13th mag."
Tom Lorenzin: 10M; 3' diameter; wait for
clear, dark S sky to resolve individual stars.
Steve Coe, observing with a 13 f/5.6,
notes: Pretty bright, pretty large, much brighter in the middle, 5 stars
are resolved at 200X. This globular grows with averted vision. It was easy in
the 11 X 80 finder.

11x80: This cluster is just
visible as a faint, small patch. A friend, observing with 8x30's, couldn't pick
it up. (suburban skies) [AS] |
