There's cloud around today and tonight, so I've had too much time messing about with Excel
I've plotted up the number of night hours (which for imaging nuts are ALL for imaging of course
) for Brisbane. I did my first all-nighter session from my home site last month during holidays, but it doesn't look like such a feat when you compare max dark hours for Bris (10:49) versus this time of year (about 7:10).
If only there were 10-11hrs hours of dark clear skies this time of the year to have a decent go at the Orion region for a change
