Moon and Jupiter, July 20, 2018

I missed the Moon's close encounter with Venus the other day. Here it is getting relatively close to Jupiter tonight.

First, an in-context shot: The Moon and Jupiter hang low in the West, a few hours before setting.

Next, a tight shot of the Moon and Jupiter.The Moon is badly overexposed, while Jupiter is little more than a small white dot.

The Moon at maximum magnification - 42x, I believe - with the brightness cranked down.

Jupiter at the same magnification, now overexposed due to the shutter staying open longer to image Jupiter's moons. Note that the moons are stretched out, indicating the distance they moved across the sky while the shutter stayed open.

Javascript Jupiter helpfully illustrates the positions of the moons of Jupiter at any given time.
