Jupiter and Venus back in morning skies

Post by starfinder »

Jupiter and Venus are back in the morning pre-dawn skies.

After seeing Venus in silhouette transiting the Sun two weeks ago, it's good to see that it has survived the ordeal. And it's good too to see Jupiter re-emerge on the other side of the Sun in our pre-dawn skies.


Here is a wide-angle photograph which I took this morning from Singapore, 17 June 2012 at 6:35am, showing the Moon, Jupiter and Venus.

On the right are the same celestial objects each taken through my 0.2m telescope at prime focus.
Jupiter and Venus are at the same scale in the close-ups, which makes for an interesting comparison, though the exposure times are different. The Moon is at a different scale (i.e. after cropping and re-sizing).

The exposure times for Venus and the Moon, both in a thin crescent phase, are identical. It shows that Venus is brighter on a "per square arc second" basis. Indeed, this was the impression through the eyepiece.
