Western Still Life
The end of a day trekking to East Boulder Canyon at the foot of Weaver’s Needle, Superstition Wilderness. I had a light pack with the camera equipment and supplies packed in on horseback.

Can You Find the Eye of the Needle?
I was a member of an expedition to Peter’s Mesa March 2008, a place central to Superstition Wilderness treasure legends. This is a sunset view, looking south, southwest. Light raking across the desolation and Miner’s Needle creates a fascinating spectacle. Ancient volcanism, apparent throughout the Superstition Wilderness, is here seen in the texture, form and type of rock as well as the mineral deposits. Miner’s Needle, like Weaver’s Needle (not seen in this view), are eroded volcanic summits. Look closely for the “eye” of Miner’s Needle, easier seen in the cropped heading photograph. To this day, hopeful prospectors search for gold nuggets.
There is one form of volcanism present today as an eerie rumble or hiss, similar to an enormous distant jet engine heard now and then during our two days on the mesa, louder and closer than an overhead plane could produce. The view includes many notable Sonoran Desert plants. Many young Saguaro cactus are in the form of green poles. Catching the dramatic light, on the ridge is a tall single flower of an Agave, known as the “Century Plant” it flowers once in a long life and dies.
Peters Mesa is named after “Old Pete” Gottfried Petrasch, father of Hermann and Rhiney Petrasch. Old Pete worked for Jim Bark for awhile in the 1890s doing odd jobs. Irregular employment gave Pete and Sons time to s searched for the Lost Dutchman Mine in the years following the death of the source of the legend, the “Dutchman” Jacob Waltz. The Petrasches were one of the first groups to search for the mine, and gold in general. They covered almost the entire Superstition range in their combined searches.
On our first day on the mesa, we came across the remains of one of these camps, on the top of Squaw Canyon, a deplorable junk pile discarded by searchers, presumably disappointed, too lazy to cart it out. That March, we were lucky to find the remnants of winter rains in the form of a meager trickle at the bottom of a shallow draw off Peter’s Mesa trail up from La Barge canyon. We had a good time of it until the trip was cut short by a storm front and torrential rains. We were back in Apache Junction before they hit.

One day before the 2019 Total Lunar Eclipse a full moon rose 4:25 pm above the Atlantic Ocean off Cocoa Beach, the “Space Coast” of Florida. We saw a power kite to the south, with the southerly winds there was time before he was on us. I took the following photographs with what was at hand, an iPhone 8.
At 50 minutes post moonrise, I included the orb in this frame as the rider tacked, rising a water crest.
A flick of the fingers to zoom in, the moon and rider are together as he rides toward shore.
This time of, Saturdays, the cruise ships depart Cape Canaveral Port. The kite is above the distant ship. It is amazing the kite allows sailing into the wind, his heading is southwest. The shore limits his progress, forcing a tack towards a southeast heading.
Or not, it seems he plans to tack to the northeast, continuing progress north up the coast. I have to wonder how he will return to the starting point?
three shots in one second
For a change of scene we visited Cape Canaveral, the beach at Cherie Down Park were an informal gathering of Kite Surfers was underway. Here is a series of action shots, one second elapsed from first to last.
Conditions were excellent: good northerly wind, the sun overcast and, it being afternoon, in the west. Surfers stayed relatively close to shore, near their starting point. I had packed the “heavy gun” camera with a tripod.
Panning the scene (swiveling on the tripod), the camera in rapid exposure mode, I pressed the shutter release and held it down.
The surfer was captured mid-jump to landing.
Adaptive optics
These views within the McMath–Pierce solar telescope enclosure were captured during a guided tour of the instrument, April 20, 2005. By way of orientation, the observation room we visited is near the location labeled “4” on the model of the following photograph or the “Observation Room” of the drawing.
We learned each of the sets of mirrors is considered a separate telescope. The first step in designing the new solar telescope was to determine the optimal image scale. Working on the spectra of the solar granules, on the physical structure of the sunspots and their associated magnetic fields, requires a considerable image size. Past experience has shown that the optimal image of the sun should be approximately 0.91 meters. The highlight of our visit to the Main Observation room was meeting with the technician operating the recently developed low-cost adaptive optics system.
Tip-tilt correction and low order wavefront correction is available with a number of portable optical benches. These are primarily used with the Main spectrograph and the Solar Stellar spectrograph on the Main telescope, but due to their compact mounting they could be used with other telescopes and instruments in the facility.
This configuration uses a rapidly deformable mirror to correct distortions introduced by the turbulent atmosphere. Using sensors to measure the degree of image distortion, the adaptive optics system adjusts the shape of the mirror accordingly and converts a blurred image into a clear one. The following image demonstrates the correction. “Low-cost” = $25,000 in 2003 US dollars. Under references is a link to a full description of the device by the creator.
A main area of study in the observatory is the structure of sunspots, which are relatively cold, dark spots on the surface of the Sun created by intense magnetic activity.
Some of the most important discoveries made at McMath-Pierce include the detection of water vapor in the Sun, the measurement of kilogauss magnetic fields (thousands of times stronger than those on Earth) outside sunspots and the detection of a natural maser (like a laser, but with a microwave instead of visible light) in the Martian atmosphere.
Over the years and technological advances, the National Solar Observatory has moved its headquarters from Tucson to Boulder, Colorado. The organization abandoned its solar telescopes at Kitt Peak and in New Mexico for a larger instrument in Hawaii, the Daniel K. Inouye Solar Telescope on the island of Maui, which began operating in 1919.
The Mirrors
These views within the McMath–Pierce solar telescope enclosure were captured during a guided tour of the instrument, April 20, 2005. By way of orientation, think of yourself at the location labeled “4” on this model. This is the only large telescope where humans can view the interior and visually experience the light paths “bouncing” between the mirrors.
McMath–Pierce solar telescope has three heliostats mounted on a 110-foot tower adjacent to a slanted enclosure. The 2.03-meter heliostat feeds a 1.61-meter primary mirror, there are 1.07-meter and 0.91-meter primary mirrors fed by a pair of 0.81-meter heliostats. Here we are inside the slanted enclosure, looking up the shaft to the tower mounted heliostats, readily identified as the three circles, the largest at center (3.51 feet in diameter). The smaller (2.66 feet) heliostats named “East” (on left) and “West.”
Built in 1962, the building was designed by American architect Myron Goldsmith and Bangladeshi-American structural engineer Fazlur Rahman Khan. It was the largest solar telescope and the largest unobstructed aperture telescope in the world. It is named after the astronomers Robert Raynolds McMath and Keith Pierce. Painted white to reflect sunlight to reduce heat accumulation, the enclosure is water cooled to prevent convection currents through the column of air within the slanted enclosure, keeping the air as still as possible along the light path between the mirrors.
In the three photographs following, we face the underground portion of the slanted shaft and (what looks to be) the 0.91 meter (2.99 feet) primary concave mirror. I say that because in some of the photographs a beam of light, to the left of the mirror, can be seen travelling further underground, presumably to the largest primary mirror. As there is only one such light beam, I conclude the west heliostat is inactive.
Here we looking up the slanted enclosure. Look carefully at the first photograph, below, to see reflections on the glass partition. The observation platform was separated from the light paths to maintain the stillness of the air column. The two mirrors of the first photograph are the third mirror, reflecting concentrated sunlight from the 0.91 and 1.61-meter primary mirrors into the observatory rooms. The mirror for the 1.07-meter primary is out of sight in foreground, I believe this set of three mirrors (West heliostats, primary and third) was out of service.
The second photograph, on right, is a close up of the third mirror for the largest primary. A foreshortened, perfectly round light disk is clearly visible.
Here we are inside the slanted enclosure, facing the underground portion of the slanted shaft and (what looks to be) the 0.91-meter primary concave mirror. In the lower right corner is the reverse side of the third mirror for the largest primary mirror, the 1.61-meter.
The Exterior
These views of the McMath–Pierce solar telescope enclosure are the preliminary to a guided tour of the instrument, April 20, 2005.
On the tower are three heliostats, plane (flat) mirrors mounted on computer-controlled platforms to follow the sun across the sky to direct sunlight to primary mirrors underground, beneath the base of the slanted shaft

Inside the McMath–Pierce solar telescope is this keyed model of the observatory. Our docent for the morning tour stands alongside.
a gorge walk
Walking around Taughannock Falls New York State Park on the solstice of 2019 starting from the Black Diamond trail head on Jackson Road, down the South Rim trail, up the North Rim Trail. We had a great deal of rain this week and the water filled the falls the full channel width.
The header photograph is a waterfall of Fillmore Glen, also in the Finger Lakes.
For a full screen view, click on the UTube icon, lower right of the video panel. The resolution is not very good so I also posted the source videos.
The movie is from the following videos and photos from my IPhone. The quality is better than the compilation video. I uploaded the following videos directly to WordPress. I was not able to get the “full view” icon to work on my browser. Enjoy
A turkey vulture soars by towards the end of the following.

Right Whales in February
No, the Manatee mailbox on Atlantic Avenue is NOT the whale sighted….more of that later. February 3rd 2022 dawned with scattered clouds to fracture sunbeams.
Walking south I made the 2+ mile point where, up from the beach on South Atlantic Avenue, is a memorable facade.
Also exotic schefflera, paths to the beach through Sea Grapes.
February is the time for Right Whale sightings on the Florida Atlantic Coast. On the beach, near the blue dot on the following map, were lines of people facing the ocean, some with binoculars and cameras with long lenses.
About 500 feet out, beyond where the wave roll begins, a person sat on a paddle board looking to my right. In the following IPhone videos an occasional black hump, roiling water, a flipper and the signature spout are visible. It is too far for identification, I call it a Right Whale from their reputation for visiting these shores in late January/February.
An hour later, I left the beach at South 4th Street to capture the following local color.
