I was playing with high phase angle macro shots (in English, the sun was nearly directly behind the leaf, just off frame to the left, actually) of this leaf. I used a medium depth of field at f/11 and high ISO to keep the shutter speed short since I was handholding the camera. I increased the contrast a little before uploading it. I was using my 70-300mm lens at 300mm focal length in macro mode with an exposure of 1/2500 seconds at f/11, ISO 1600.

This view of Kitt Peak is from just above the turnoff from highway 86 onto 386 that winds up the mountain. The most prominant dome near center is the 4-meter Mayall telescope building. This image was taken with the kit lens on my 20D at 55mm focal length. The exposure was 1/400 seconds at f/5.6, ISO 100.

Sunset was spectacular despite the clear skies on Saturday night, especially for an Astronomer. The sun is just above the horizon with the Spacewatch 36 inch telescope almost a silhouette in this image taken with the kit lens at 18mm focal length on my 20D. The exposure was 1/250 seconds at f/5.6, ISO 100.

Along Kino Blvd, where the road transitions from Campbell Avenue in Tucson is this statue honoring Father Kino, an early explorer of the Southwest who founded a large number of missions in the area including the San Xavier del Bac mission south of town. This image was taken with the kit lens on my 20D at 55mm focal length as I waited for a traffic light to change. The exposure was 1/8000 seconds at f/5.6, ISO 1600. The image was converted to B&W in Picasa with a filtered B&W conversion in the green.

Kitt Peak lines the horizon near sunset from Tucson Mountain Park. Some of the domes are quite prominant, including the largest dome on the mountain for the 4 meter Mayall telescope on the right and the distinctive McMath Solar telescope on the left. This image was taken with my 70-300mm lens at 300mm focal length with an exposure of 1/13 seconds at f/11, ISO 100 (with the camera on a tripod).

(You have to sing the title of this blog entry to the Beatles "Here comes the Sun" to get the full effect....) The sun is moments from dipping below the horizon to start another night of observing. This one is from my last observing run a week or so ago. This image was taken with my 24mm lens with an exposure of 1/1600 seconds at f/5.6, ISO 800.

The Tucson High School Steel Drum band called Jovert had their annual concert last night. My son has participated in Jovert for all 4 years that he has been at Tucson High. Each of the 4 steel drum classes played several pieces each. The group has been run by their director Khris Dodge and produces CDs of their music every year which are available on their website. This image was taken with the kit lens on my Canon 20D at 34mm focal length with an exposure of 1/100 seconds at f/4.5, ISO 800.

Our last concert in the main theater at Tucson High School tonight after 8 years of concerts there with our two children suggested an abstract of the chandelier that hangs over the the theater. This image was stretched and converted to B&W in Picasa. The exposure was made with the kit lens at 54mm at 1/50 seconds at f/5.6, ISO 800.

These two bovine specimen were resting along the road up to Kitt Peak. I slowed to a stop, took a couple pictures and after "Mooing" at them (an old tradition anytime I've seen cows...), I waved and as I accellerated off, exclaimed "Maybe I'll eat you later!"..... This image was taken with my 24mm lens with an exposure of 1/640 seconds at f/5.6, ISO 100.

The Spacewatch 36 inch telescope at work on Kitt Peak. The telescope is lit by scattered moonlight as it surveys for asteroids. This image was taken with my 24mm lens on my Canon 20D during a timelapse sequence with the camera riding the dome. The exposure was 30 seconds at f/1.8, ISO 800.

The author of this photoblog stands next to an old friend - the Spacewatch 36 inch telescope on Kitt Peak. If I look just a bit fuzzy, I had to stand still for the duration of the 30 second exposure which was one of the first in a timelapse sequence. Twilight was still quite heavy around 25 minutes after sunset and the exposure was set for getting the moonlit telescope and stars in the sky through the slit later, so the image is a bit overexposed here and there. This image was taken with my 24mm lens on my 20D with an exposure of 30 seconds at f/1.8, ISO 800.
