Here's a small collection I took last weekend from a Bortle 2 location in Central Victoria. Man, what a difference it makes to be away from city lights. None of these were more than 25 mins integration. Rho was the longest at 24 mins, 12 x 120 seconds, 800iso, 50mm lens, f 5.6. Next was M8 and M20, 15 mins, 15 x 60 seconds, 1600iso, 135mm lens, f 5.6 and finally Carina, 5 mins, 5 x 60 seconds, 3200iso, 135mm lens, f 5.6. All shot with a modded Canon 550d using a UV/IR cut filter and iOptron Sky Tracker Pro mount. Stacked in DSS, level adjustsments and noise reduction in STs, colour correction, cropping and resizing in Photoshop.
