Here are few more of my favorites picture I took:

I like this one I this one with the twisted cottonwood.



One of the advantages of having the key to the tower is you can go up anytime you want. Here's a view from the gallery of the sunset over Lake Michigan.



A little later, I took this one. The little white dot to the left of the tower about halfway to the edge of the picture is Venus.



And here is a picture of the lens. It is a third order fixed and flashing lens. As you can see, the upper third of the lens is actually separate from the bottom. This upper third portion used to rotate producing a flash characteristic that was steady on for 25 secs and then a more brilliant beam for 5 secs. The current flash characteristic with the electric bulb is 5 secs off - 1 sec on. I timed this picture to coincide with the flash of the light.
