On ya Steve ,
I was there the previous Tuesday night and only lasted to 11.30pm
That obsscure Galaxy you mentioned piques my interest as it is the Circinus Dwarf discovered at Mt Stromlow in 1978. We are looking through a tunnel of low dust as it is of very low galactic declination
Ron uses the faint stars ( zero mag) in the coal sack to gauge the trasparency. The night I was there the 6.2 star was just vis. Sounds like the rest were visable for you
Hope to chat up next month .Zub.
ps hi Janette
