Burrowing Owl on stump

 
After following the owl back and forth across the riverbed, he landed on this tree stump. This image was taken with my 70-300mm zoom at 190mm focal length with an exposure of 1/1250 seconds at f/8, ISO 400 on my Canon 20D. 

Burrowing Owl

 
I found this Burrowing Owl perched along the west bank of the Santa Cruz river south of Irvington road in Tucson. We both watched each other closely as I crept closer to him, snapping pictures until he launched himself into the air and flew across the river to the other bank (the Santa Cruz river is almost always a dry riverbed except after rains). This image was taken with my 70-300mm zoom at 190mm focal length on my Canon 20D with an exposure of 1/1600 seconds at f/8, ISO 400. 

This one's for Frank...

 
One nice thing about working on a college campus is the scenery. My friend Frank "made" me post an image of one of the many lovely coeds who grace the University of Arizona campus. This image was taken with my 70-300mm zoom at 300mm focal length on my Canon 20D. The exposure was 1/200 seconds at f/5.6, ISO 400. I added a little glow in Picasa. 

West side of Old Main

 
This is the view of the west side of Old Main with the Old Main fountain. This image was taken with the kit lens on my 20D at 18mm focal length. The exposure was 1/160 seconds at f/11, ISO 100. I used filtered B&W in Picasa with a red filter and warmified the image to sepia tint it. 

Backlit bird

 
Got a picture of this bird about 20 feet away backlit on a rock. This image was taken with my 70-300mm zoom at 300mm focal length. The exposure was 1/250 seconds at f/5.6, ISO 400. 

Big Red

 
Found this flower next to Old Main - the UofA groundskeepers do a wonderful job maintaining and creating flowerbed displays around our campus. This image was taken with my 70-300mm zoom at 168mm focal length. The exposure was 1/60 seconds at f/5.6, ISO 800 and I used a little fill flash. 

Triangles and lines

 
Here's an abstract of sorts. Any guesses at what it is? This image was taken with my 70-300mm zoom at 168mm focal length. The exposure was 1/1600 seconds at f/5.6, ISO 400. 

A Man and his audience

 
This stage is on the west end of the UofA mall in front of Old Main and the Student Union. Many weekdays finds singers or bands playing here. This image was taken with my 70-300mm lens at 133mm focal length. The exposure was 1/640 seconds at f/8, ISO 200. 

Glass Ceiling

 
This glass ceiling is one of the centerpieces of the University of Arizona Student Union Memorial Building. This image was taken with my 70-300mm zoom lens at 70mm focal length. The exposure was 1/1250 seconds at f/8, ISO 200. 

5:53PM

 
The clock tower at the Studen Union Memorial Building shows the time of the image. Below the clock is the ships bell from the U.S.S. Arizona, salvaged from the wreck at Pearl Harbor. This image was taken with my 70-300mm lens at 300mm focal length with an exposure of 1/3200 seconds at f/5.6, ISO 400. 

Cactus Wren and lizard

 
I found this Cactus Wren outside of Old Main on the UofA campus. He seemed to be playing with this lizard (which seemed certainly dead), pecking at it and tossing it around, chasing it about the area. This Gecko didn't have enough Bird insurance, I guess.... This exposure was at 300mm focal length with my 70-300mm zoom. The exposure was 1/100 seconds at f/5.6, ISO 800. 

Turkey Vulture

 
This Turkey Vulture was hunting for Easter eggs (or maybe the Easter Bunny...) as he flew over Collosal Cave Mountain Park on Easter Sunday. This image was taken with my 70-300mm zoom at 300mm focal length with an exposure of 1/800 seconds at f/8, ISO 400 on my 20D. 

Phainopepla

 
I found this Phainopepla in Collosal Cave Mountain Park on Easter Sunday. This image was taken with my 70-300mm zoom at 300mm focal length. The exposure was 1/1000 seconds at f/8, ISO 400. 

Peeps

 
One of the more popular Easter candies are Peeps - these are pink peeps.... This image was taken with my 70-300mm zoom at 300mm focal length. The exposure was 1/250 seconds at f/8, ISO 400. 

Pineapple still life

 
We found some pineapples at the store today and at 2 for the price of 1, we had to buy a pair. This image was taken with the kit lens on my 20D at 25mm focal length. The exposure was 1/6 seconds at f/13, ISO 100. 

Another sunset

 
Last nights sunset was very pretty, after increasing clouds all day. This image was taken at 34mm focal length with the kit lens on my 20D. The exposure was 1/80 seconds at f/7.1, ISO 1600. 

Backyard sunset

 
This is the view of a sunset a few nights ago from my backyard. The exposure was 1/60 seconds at f/5, ISO 100 with the kit lens at 18mm focal length on my 20D. 

Speaking of radio telescopes...

 
This is the 12-m millimeter wave telescope also onthe southwest ridge of Kitt Peak. It used to be run by the National Radio Astronomy Observatory but now is run by the University of Arizona. It is very good at mapping out the giant molecular clouds. Way back when I wa an undergrad, one of my best friends worked on such a project and I visited him one night while he observed on this telescope. This image was taken at 300mm focal length with an exposure of 1/500 seconds at f/5.6, ISO 100. 

VLBA antenna

 
This radio telescope is part of the Very Large Baseline Array of telescopes spread around the globe to make a radio telescope effectively nearly the size of Earth. This dish is located on the Southwest ridge on Kitt Peak. My friend Richard visited the Very Large Array (VLA) in New Mexico where a set of radio telescopes are located along 3 radial tracks and can be moved for different typs of observations. His images can be found on his webpage starting with this image. This image was tkaen at 300mm focal length with my 70-300mm zoom. The exposure was 1/500 seconds at f/5.6, ISO 100. 

Lichen Macro

 
The last time I took a macro shot of some lichen, the colors of the lichen were rather mutted. This time the lichen is a bright green, growing on some granite n Kitt Peak. This image was taken with my 70-300mm zoom at 300mm focal length in macro mode. The exposure is 1/500 seconds at f/5.6, ISO 100. 

Herc Flyover

 
Before last Thursday's season opening Sidewinders game, this Air Force C-130 Hercules flew over the Tucson Electric Park. This image was taken with my 70-300mm zoom at 214mm focal length. The exposure was 1/400 seconds at f/5.6, ISO 100. 

3 for 4

 
My folks and I went to the season opener for the Pacific Coast League Tucson Sidewinders who hosted the Salt Lake City Bees. The pitchers duel lasted less than an inning and while the Bees won 9-3 and there were lots of mistakes on both sides, the hitters definitely appeared to be ahead of the pitchers tonight - there were 27 hits between the two teams. This image shows firstbaseman Chris Carter of the 'Winders hitting his 3rd hit of the night as he went 3 for 4 with two singles and a double. Not a bad way to start off a season. This image was taken with the 70-300mm zoom on my 20D set to 133mm focal length. The exposure was 1/400 seconds at f/5, ISO 1600. 

Stormy Sunset in B&W

 
I decided I like the B&W version of this image better than yesterdays color version. Seems more dramatic and no matter how much I played with the white balance it just didn't quite seem right in color.... I selected a red filter in Picasa to increase the landscape contrast and to darken the storm clouds a little. 

Stormy sunset

 
Dark clouds pass north of Kitt Peak last week in this image. The domes, from front to back, are the Spacewatch 36 inch, Steward Observatory 90 inch Bok telescope, and the Kitt Peak 4-m Mayall telescope. This image was taken with the kit lens on my 20D at 18mm focal length. The exposure was 1/20 seconds at f/5.6, ISO 800. 

Softball sunset

 
While our game did not go too well, the sunset that happened during our game was quite spectacular. This image was taken with my 20D with the kit lens at 18mm focal length. The exposure was 1/80 seconds at f/5.6, ISO 800.
