G.O. by moonlight--well, by some light

Love a rocket
After all the shots of earth's satellite I've taken, I feel as though I need to include this moon (which was a bit easier to shoot) inside the Griffith Observatory.

Fun with exposure / 42 degrees
The Foucault Pendulum in the central rotunda of Griffith Observatory. This 240-pound ball swings on a cable over a this circular pit with a lighted ring around the perimeter.
Here's two virtually identical shots of the ball. Both use the same aperture setting (F/3.5, for the photographically inclined).
Here's what it looks like with a 1/15 second exposure:
Here's what it looks like with a 1/125 second exposure:
Hey look: That lighted ring is divided into 42 sections (numbered 0 - 41). All because we let the lens be exposed to the light for 1/110th of a second less (shorter than the blink of an eye).

"Photo" means light, doesn't it? Imagine that: Photography depends entirely on light.

Speaking of the 42 sections: They're not only designated on the lighted ring:
But also around the upper lip of the wall around the pit (directly opposite the corresponding number on the ring below):

Meridian
At the Griffith Observatory, in the "Gottlieb Transit Corridor"; had it been a sunny day this would have been focusing the sun's rays, but it was still interesting after the rain:

Spikey
On some other trees in the courtyard of the building there's no leaves but these spikey pods.
(If you have any idea what these trees are named, please leave a comment. I'm not as much of a tree expert as I would like.)
UPDATE: These are American Sweetgum.

After the rain
A series of shots focusing on using manual focus to capture these raindrops on the tree leaves outside my patio. (Absolutely no auto-focus with any of these.)
(The aperture and exposure were also manual, but hey, big deal, right?)

Tunnel, facing east (mostly)
From the west end of the 2nd Street tunnel (the other end of the tunnel here).
