Took these shots last Tuesday morning, while watching the Venus/Uranus conjunction at Terrigal.
They didn't turn out as nice as I would've hoped.. the shots when it was still dark required a high ISO (800) and a long exposure to bring up any foreground (as well as processing levels in photoshop).
The shots just before sunrise were too overexposed just at the horizon, because I didn't use my ND grad filter to block out the light coming in the top half of the lens.
Ah well, learning experience.
In the first 4 shots, Mercury also makes an appearance as the brightest "star" close to the horizon (slightly to the right of Venus).
Those shots are wonderful! They are the type of astrophotos I really like...a bit of astronomy and a bit of landscape. Images 3 and 4, 4 in particular, are great and you could easily imagine yourself to be looking at the sky from another planet.
I agree with Peter, I like the shots just as they are, IMO they convey the feel of dawn and are beautiful to look at. May be worth trying fill flash if you want to get some foreground effects next time.
