I reprocessed one from duckadang last year, the veil and a new one from last year - lagoon etc, both with the cooled 350d and 200mm lens. Man i have heaps to learn the veil is 1200 seconds at iso 1600, the other is 900 seconds.
They look great. I really like the depth of the star field you can capture with the 300 mm lens.
I've given up at the moment. Even if i did get out there I know Sydney would trick me and after I set up the clouds would come in. I nearly went out last night as I could see heaps of sky and it's been ages since i took a photo, but really it would have been terrible, high level cloud and a full moon.
