After a another cloudless day, a trip to Kumeu to do some observing was on the agenda. Michelle came along as well, with the kids being looked after by Michelle's parents. The care was already packed from yesterday, as I tried to go down south the previous evening. However last night clouded over, just on sunset. No cloud in sight tonight so off we went. Alastair Duhs and Guy Thornley were already there, and I set up on the drive. Dave Moorhouse arrived about 30 minutes later. My Argo Navis was preloaded with lots of nice objects not seen in awhile. Planned to be out for just on 2 1/2 hours. |

Very cold night, with Michelle rugging up with a hot water bottle. Nice coffee break half way through to keep the blood flowing. Argo Navis pointed very well all night, no realignments etc, just works well. Spent a little time in Libra crusing around looking at some of the brighter galaxies, a few nice planetary nebulae. Comet C/2008 Q3 Garradd was bright with a nice compact tail. Nice to be out again, probably only once this month, but that's OK. |
