Hi. I managed to spot the comet early Monday morning (18th Nov) from here in SE Melbourne (before the morning fog/cloud rolled in). Using Spica as a nice ref point - it took the C5 to spot directly, no luck in the 72mm WO Megrez, and certainly nothing in the 8x42 ED binos. The 125mm SCT held it (albeit with averted vision) right up until 5:15am - the Sun then being 8deg below the horizon, and ISON roughly 10deg above. I don't think I'd give it another go unless it really flares! Here's hoping for a daylight display, but I'm not holding my breath
Clear skies!
Regards, Dean
