Feeling so starved of DSO observing, I set an alarm for 2 am anticipating a clear sky. Scope was set up and ready to go, but when I went out, there were many bands of stratocumulus marching across my darkening sky. The satellite image showed a bit of a gap, so I waited for about half an hour to nab some of the December observing challenge objects. I managed 2 between cloud bands. But it struck me that I dind't find this too frustrating. I was just so glad to see some stars between the clouds. I could point the scope at something familiar and watch it for a few seconds before it disappeared. I think this is a mark of how desperate observing has become recently. And I did see a few Geminids - very nice.
So here are my princely 2 DSOs out of 1 1/2 hours observing
Telescope 410mm (16”) f4.9 tri-dob reflector
Eyepieces 28mm UWAN, 17,13,9 mm Naglers, Paracorr
Navigation: Night Sky Observer’s Guide
Seeing good 2/5
Transparency excellent 7/7 when no stratocumulus cloud
0230
NGC 2243 OC in Canis Major
Dia 13’ Vmag 9.4 Trumpler type I2r
175X A small distinct object with a smattering of resolvable stars against an irregular background haze which is square at the southern edge but tapers irregularly at the northern end. About a dozen resolvable stars. Appears to me about 9’x7’
And the clouds roll in and then away again…
NGC 1261 GC in Horologium
Dia 6.8’ Vmag8.3 Class 2
175X distinct GC, no distinct core, but quite a regular and compact GC with fairly even spread of brightness across the bulk of the disc and then a thin fainter halo surrounding this. Many faintly resolvable stars. Just to the NE there is a bright foreground star and a bit of a darker patch in the cluster near this star and a few dark lines on the other side of the GC. No strands of stars of haze distracted from the GC – it appears very intact.
