The computer has just finished calibrating 100 lights, 20 flats, 20 bias and 60 darks. 25GB later I need my external HD as backup. 10x10 panel mosaic with a 10-15% overlap. They certainly aren't as deep as my last attempt, even through the fog! The difference between 60&120s is evident. Keeping it at 60s did allow me to start imaging at 35° and finish at 31° above the horizon.

Having a dark site in Heathcote I have developed a bit of a "sweet spot" for Shiraz.
