Moonrise over Tucson II

Here's another view of Wednesday night's moonrise. Turns out my friend Dave was set up only a few hundred feet away taking photos of the moonrise. This image was taken with my 75-300mm lens at 130mm focal length with an exposure of 2 seconds at f/8, ISO 100.

Moon rise over Tucson

We had a pretty full Moon rise over Tucson today. On the way home, I detoured partway up Sentinal Peak (A Mountain) to get this view over downtown Tucson. This image was taken with my 75-300mm zoom at 75mm focal length with an exposure of 4 seconds at f/8, ISO 100.

Morning Twilight

As the morning twilight grows in strength, telescopes on the north end of Kitt Peak prepare to shut down. In this image, the Spacewatch 36 inch telescope left of center is visible with the Steward Observatory 90 inch Bok telescope and KPNO 4-m Mayall Telescope near center. Just right of the 4-m is the glint of an Earth orbiting satellite. The Big Dipper is near the top of the frame. This image was taken with my 10mm fisheye lens with an exposure of 59 seconds at f/2.8, ISO 400.

90 inch in moonlight

Here's another image from last months observing run on the 90 inch Bok Telescope. The Moon shines in the upper left and Cassiopeia is visible through the aperture of the dome just below center. This image was taken with my 10mm fisheye lens with an exposure of 30 seconds at f/2.8, ISO 400.

90 inch and the Moon

I took this image last month when we were using the 90 inch Bok Telescope on Kitt Peak. We were waiting for the moonlit cirrus to clear out, so I set up my camera and used my LED flashlight to indirectly light up the telescope. The telescope itself is green (as you can see in some of my other photos) but the LED flashlight gives it a blue tint. This image was taken with my 10mm fisheye lens with an exposure of 30 seconds at f/2.8, ISO 400.

Iridium Flare

It's a bird, it's a plane. Well, actually it's an Iridium satellite flare and a nice bright one, with the prediction being magnitude -8! This image was taken from the landing outside the 1.8-m with my 10mm fisheye lens set at f/2.8 with an exposure of 60 seconds at ISO 400.
