The skies are pretty dark at Twin Peaks - a bit of glow from Sydney in the east though. I can't often get there though. My usual site (Blue Hill) isn't too bad but where I live in Oberon itself is not too flash since the expansion of the factories in 1995/6...
No, so far I've had no success with Mars at all, and time is passing by. It's not often that I have nigh time committments lately, but those that I have had have coincided with the few clearish nights I could've had...
As for focussing, well finding out about the jetstream maps has been a big help... its a challenge to focus sharply on something that isn't clear anyway... but the Varimagni finder on the OM is also the wasp's nipples! If you can get faint (on the moon) detail sharp, you know you've got good focus (and good seeing). Still got some work to do on my focussing procedure for the afocal stuff (digital)... playing with ways to compensate for my eyes that aren't what they used to be, Hartmann masks, etc, etc.... all good stuff to experiment with...
