Well I spent an hour out there - not -6 yet though. The seeing conditions were terrible. Everything was fuzzy.
Worked through some new objects (for me!) in Ara and Corona Australis:
IC 4651 - OC in Ara
NGC 6352 - a very faint, diffuse GC in Ara
NGC 6362 - another fairly diffuse GC in Ara
NGC 6541 - a quite beautiful GC in Corona Australis - very underrated!
Plus a few oldies...
Wasn't any colder than other nights yet, but the clear skies should get it down in the wee hours. Worst I have had this year (for observing) has been -5 and it isn't that cold yet tonight.
