Some recent shots I took from my visit to Mudgee (first image, shot on 31/08/13) and from Hargraves Lookout (second image, shot on 07/09/13).
I originally thought that the orange glow in the bottom left corner of the Mudgee shot was light pollution from Sydney. But it has since been pointed out to me that its more likely to be the back burning that took place that weekend in the mountains (over 100km away).
In the Hargraves Lookout shot, you can notice that the stacking didn't go too well (in the corners), possibly due to the tree or cloud which was coming through. I was going to crop this out but I like Venus in the shot. Also its the first time I have captured the Zodiacal Light.
These shots are both stacks of 5 x 30 second exposures. Shot at 8mm using the Sigma 8-16mm, which has an aperture of f/4.5 at 8mm. Because of this I'm finding I have to bump up the ISO so high (ISO 12800!) that single frames from the 60D are unusable. Stacking really has helped suppress some of the noise from the 60D. Topaz DeNoise also helps a lot here.
Really liking the results others are getting from the Canon 6D coupled with the Tamron f/2.8 14mm. I've had the 60D for a couple years now, might be time to upgrade to full frame
