This is an image of an iridescent cloud. Notice the varied colors above and below the saturated Sun. Exposure details not available at the moment (I'm away from home and can't read the exif data in the image with anything I have running under Linux - I figured the Gimp would be able to, but can't find it....)

This image was taken on October 23 just before sunset from the Linda Vista Trail west of Pusch Peak. This is the backside of Pusch Peak which from Tucson is a very distictive pyramid shaped mountain on the extreme west end of the Catalina Mountains north of town. This image was taken with my 24mm lens attached to my 20D. The exposure was 1/250 seconds at f/11, ISO 800.

The Pride of Arizona Marching Band of the University of Arizona has 250 of the most dedicated student performers in the country. On game day (last Saturday morning), they had a last rehersal and run through. I'm proud to be the parent of one of the Pride, currently led by Professor Jay Rees. This image was taken with my 70-300mm zoom lens on my 20D set to 133mm focal length. The exposure was 1/2500 sec at f/5.6, ISO 400.

I went to the University of Arizona - Stanford Football game on Saturday afternoon and of course, took my camera. Wildcat Syndric Steptoe (#1) has just caught a short pass and evaded the diving Cardinal player on the left and it making a turn to try and get into the endzone on this play. This exposure was made with a Sigma 70-300mm zoom on my 20D with the focal length set to 108mm. The exposure was 1/2500 sec at f/4, ISO 1600.

One good thing about clouds in the sky are the various types of phenomena you can see in the sky, from rainbows to arcs and haloes. In this case, a sundog (also called a Parhelia) appears, captured left of the Sun in this image taken on October 14 with a 24mm lens on my 20D. The exposure was 1/1600 sec at f/8, ISO 100.

Domes and Satellites. This image was taken in the early evening of October 5 and shows from left to right, the domes of the Spacewatch 36 inch, the Steward Observatory 90 inch and Kitt Peak 4 meter telescopes. You can see a satellite just above the 4 meter dome and you can also see Mike, our observer at the 36 inch in the "pulpit" at the top of the dome checking out the weather. This images was taken with a 24mm lens on my 20D. The exposure was 30 sec at f/1.8, ISO 1600.

Antares gone Supernova? Not this time - Antares was washed out in the glare just about half a degree north of the center of the Moon as the crescent Moon passed just south of the brightest star in Scorpius whose stinger rises just below the faint glow of the Milky Way on the left side of ths image. The Moon is washed out in this image which was taken with a 24mm lens on my 20D. The bright "star" on the right side is Venus in the fading twilight and the greenish glow just left of center is a reflection of or lens flare from the overexposed Moon. There were plenty of pesky moonlit clouds all over the sky at the time of this image, taken on the evening of October 7. The exposure was 30 seconds at f/1.8, ISO 400.

Moonlit Milky Way. Ths image was from the evening of October 7. The crescent Moon was setting in the west, lighting up the domes and clouds while the Milky Way in Sagittarius shines through in spite of the moonlight. This image was taken with my 24mm lens on my 20D. The exposure was 20 sec at f/1.8, ISO 1600.

ISS over Kitt Peak. This image is of the International Space Station (ISS) as it passed over Kitt Peak the morning of October 5. This image is with my 20D using a 24mm lens. The exposure was 30 sec at f/1.8, ISO 1600. I'd left the camera outside taking some pictures and in high humidity, you can see a bit of fogging on the bottom of the image - oops.

After a long strenuous hike with heavy backpacks up the Old Baldy trail up the northwestern face of Mount Wrightson in the Santa Rita Mountains south of Tucson, we turned the last of the 32 switchbacks that this trail makes up a narrow canyon just below Baldy Saddle north of Mt. Wrightson and finally found the old familiar saddle. This is the view east not too far from where we camped that night. In the distance, not easily seen in this image, but easily seen in the binoculars my friend Frank is holding, was a small fire in the distant mountains. Little did we know at the time, though we both recognized the large amount of fuel and dead trees along the trail and the fire danger, but just two and a half months later the Florida Fire burned through the Santa Ritas north of and around Mt. Wrightson, almost certainly burning much of the area we hiked through and camped in - almost certainly this area was burned (check out some of my early photos in this blog, particularly the images from August 15 and 16. In the night-time double stroke lightning shot from August 15, Mt. Wrightson's summit is just left of the left bolt and Baldy Saddle is the saddle just left of Wrightson, the first dip in the long ridgeline north (left in this image) which is covered by orange specks of fire hotspots. This image was taken on April 21 of this year with my Canon A75, the lens was set to 5mm and the exposure was 1/640 sec at f/4.6.

I took this picture of the Spacewatch 36 inch telescope on March 12 this year with my Canon A75. I set the lens to 5mm focal length and attached the wide angle converter. The expsoure was 15 seconds at f/2.8. This picture shows the oldest telescope on Kitt Peak. It's not the 36 inch (the white tubed telescope) which is the 2nd old telescope on Kitt Peak - the oldest is the brass colored Alvin Clark and sons refractor on top of the 36 inch. The 36 inch telescope is used to survey for asteroids and was the first telescope used to survey regularly for asteroids using an electronic detector starting in 1984 - pioneering the way all the major surveys find asteroids today. Check out the Spacewatch website to learn more about the old girl adn the rest of the project.

Sticking with the silhouette theme for one last day, I found this old style lamp on the UofA campus on June 1st this year. This image was taken with my 20D using the 18-55mm kit lens at 18mm focal length. The exposure was 1/200 sec at f/16, ISO 100. I placed the Sun directly behind the lamp housing in order to make it appear to glow while blocking the glare of the sun.

I saw these arcs and halos around the Sun on March 2. The halo is pretty common given the right type of clouds, but the Upper Tangential Arc is a little more rare (the arc heading right off the top of the halo). This image was taken with my Canon A75 with wide angle adaptor, the lens was set to 5mm and the adaptor would have made that about 3.3mm. THe exposure was 1/1600 sec at f/5.
