There are two out that way, Mount Blackheath lookout and Hargraves lookout. Both are off the same road from Blackheath and only a fork in the road splits them, one to the north and the latter to the south.
Which is better? Hargraves has a wider aspect of the sky, but very exposed. Mt Blackheath's east is obstructed by trees, but it is more sheltered and has a couple of fire places, which are most welcome in the depths of winter. Hargraves also has more of Katoomba's sky glow, Mt Blackheath bugger all.
Both are also very isolated. Roos are a concern also at both while driving to and from each! Which then? Toss of a coin really.
I can't make the date,

. Work reach's its busiest for me before Christmas then. <sigh> Another long wait for me...
