Sometimes a tree is a good place to sun one's self. Northern Water Snake (Nerodia sipedon).

It was an interesting Sunday. This morning we viewed the “Rembrandt in America” exhibit showing at the Cleveland Museum of Art. It’s amazing how good some 300+ year-old paintings can look! The exhibit also shows what can happen when a great artist becomes commercially successful in his own time. Works by or contributed to by Rembrandt’s workshop staff, students, and others can be and often have been attributed to the artist himself. The years and the treatment of the paintings by their successive owners have had huge influences upon what we see today. So what does “a Rembrandt” look like? Well… I know what some of them look like but left the show knowing that looks can be deceiving.

After lunch we went home, changed to suitable clothes, and headed to Hinckley Lake to take advantage of the bright and warm (now 78 degrees F) afternoon. I carried about 20 pounds of DSLR camera gear. She Who Must Be Obeyed carried her new, lightweight Canon one-piece camera with an extraordinary built-in zoom that can range from macro to 800 mm equivalent telephoto! Walking along we merrily shot photos of flowers and plants, water and bark. Then I spotted a big, dark bullfrog resting upon a piece of wood at water’s edge. A few photos. Then She said, “look!” I looked where she was pointing and, to my surprise, saw a nice-sized Northern Water Snake (Nerodia sipedon) coiled up sunning itself… about six feet above the water in a tree! The snake posed patiently for photos and when we’d had enough, we moved on. Snake stayed put. Not much farther along we spotted another water snake suspended in the branches. Some way farther, another though this one stretched out along a log jutting from the water. We also encountered one large and one baby garter snake, though they were not nearly so impressive as the tree-climbers.

At home, She had me take a look at her photos. Several were quite wonderful in technical quality — solid focus with beautiful detail of the snakes and the frog. With all my fancy gear, I have to say this wasn’t my best day. {sigh}

Still in all, it was a fine day looking at old paintings and shiny new snakes.

Shooting stars

Nope, not the 'Little Dipper' these are the stars of the Pleiades cluster

A few nights ago I did a bit of fixed-tripod astrophotography to attempt to capture the conjunction of Venus and the Pleiades. I had to work pretty hard to salvage the conjunction photo but wasn’t all that pleased with the results. Since I had a decent clock-drive sitting mostly unused, I decided to mate my camera to that and see what I could get. Not a pioneering venture, to be sure, but I’ve actually never piggybacked a camera to a telescope before! A quick trip to the local Ace Hardware store produced the stainless steel quarter-inch screw and a pair of rubber automotive washers I’d need to mate the telephoto lens tripod mount to the telescope’s dove-tail mounting bar. Shortly after dark on this clear but full Moon-lit night, I toted the Orion SkyView Pro tripod and mount out to the sidewalk. After a rough alignment with Polaris, I attached the camera rig to the mount and did 10 exposures: about five each of Orion’s sword and the Pleiades star cluster — both in the twilight western sky. I’ll definitely need to use the DSLR’s advanced feature that allows its view finder mirror to flip up before beginning exposure — several shots were ruined by vibration. Focus was a bit more of an issue than I expected. Tracking? Well, I expected it to not be perfect but it appeared good enough for exposures of up to 15 seconds. Given all that, I’ll share my results here. I know they’re not very good but I also know that, using this same camera gear with better mount and alignment, I’ll be getting some very nice images of the stars in the not-too-distant future!

Return to the rookery

A big bird can carry a big stick. Herons don't, however, talk softly.

I had the day off to attend to some personal business. Thing is, it wasn’t all-day business and with the morning dawning clear and bright, I headed back to the heron rookery we enjoyed a bit more than a week ago. The community nesting site is alongside Bath Road south of Peninsula, Ohio.

A heron slows and flares up to gently land on the branches of a tree.

The Great Blue Herons were still at their nest building with big birds swooping down from the trees, collecting twigs, branches, and other materials, then lofting to the treetops.

Great wings spread the heron lands, its mate barely visible in the nest.

Alighting in the thin branches and on their nests, the collected twig is delivered to the waiting mate and appropriately placed to become part of the nest.

The arriving heron delivers the twigs and strokes his mate along her side.

Lunging from the nest, the collector begins another cycle of careful selection and delivery of construction material. Soon chicks will appear in the nests and then, for mom and dad heron, the work really begins!

Off again, the Great Blue takes flight seeking more nesting material.

It was a fine morning of bird photography and I filled two memory cards with images. Once back, I deleted a few pictures but most were worth keeping and some were quite good; I’m happy to have shared a few here.

Venus joins the “Seven Sisters”

Venus, at the bottom of this picture, graces our sky with the Pleiades.

A clear evening sky gave me the opportunity tonight to see planet Venus floating right below the beautiful naked-eye star cluster, the Pleiades (M45). The combination was beautiful through my binoculars, just before 8:30 PM EDT. I decided to make a quick try at recording the scene with my camera and 400mm telephoto lens mounted on a tripod. The problem, of course, is that an exposure of any decent length will cause the stars to form curved lines as they appear to move through the sky. Even my brief five-second exposure was no different… it looked great in the camera’s built-in LCD preview panel but pretty sad on the big computer screen. So I used a bit of crude Photoshop work to round out the stars. The result won’t make the pages of Astronomy or Sky & Telescope magazines but it’s not too bad and saved the shot. This, and a very intriguing result from the nearby Orion Nebula (M42), makes me eager to get out on another clear night and spend some time with the camera mated to a tracking mount or piggybacked on a telescope!

The Photoshop work, by the way, was a duplicate layer used with “blending mode” set to “Darken” and then used as an offset filter. The offset filter is nudged around until the best combination of masking and brightness is found. I found the process described in a forum discussion on Cloudynights.com.

No pictures!

"No pictures!" From my series of test images using my new 400mm telephoto lens.

It’s a nice shot!

Test shot of a Cardinal on a cloudy spring day.

I took some time today to try out what I hope will be an excellent addition to the small collection of lenses for my SLR cameras: Canon’s EF 400mm f/5.6L, USM. The super telephoto is a medium-weight (some would say heavy-) beauty, solidly-built with an attached, retracting lens shade, and ample manual-focus grips. A “prime focus” optic, it features a minimum number of high-quality glass elements, only two electronic switches, and no image stabilization; those reduced features help keep weight, complexity, and price down. I wondered whether I could use the big new glass handheld for wildlife photography. I found the answer is a definite maybe! The lens and my EOS D50 camera make for a hefty load though that, in itself, doesn’t prohibit handheld shooting. What I’m not used to, however, is the lens’s rather distant close-focus distance of about 3.9 meters and its very shallow depth of focus (a function of focal length and aperture, of course). The distant close-focus can be a problem since I’m used to my 70 – 200mm lens’s ability to focus to about 1.2 meters. On nature hikes, I’ll either need to carry two cameras or be prepared to swap lenses a lot more frequently than I do now though 400mm is an awful lot of lens for most of our hikes. Of course, a long lens is a tool you use for specific shots so, if I’m to go out birding, I’ll probably want and need to start carrying the lens and camera combo mounted to a tripod.  The lens comes with a tripod mount collar (Canon didn’t include that on my pricey 70 – 200mm zoom) and I did find that, even with my steady hand and high shutter speeds, I could have used a bit more physical stability today. Image quality appears to be very good to excellent (as expected), auto-focus is generally quick and silent. Shots at f/8 have very shallow depth of focus which I’m not used to but which can be really wonderful for isolating a subject from background clutter. The down side of shallow focus is that you’d better be bang-on target or the subject won’t be sharp as you would like. It will be fun to try this glass out in astrophotography, piggybacked to a telescope as a guide during long exposures! (The optical elements of this telephoto are much better than those of my telescope.) My test shots today included a nuthatch (that took flight as I fired the shutter), some Canada geese, a squirrel, a few spring wildflowers, etc. No wading birds at the lake today. My favorite, however, was my final shot of the session at Hinckley Lake: I heard a Cardinal singing and spotted it high in a tree. I walked to a point almost directly under the bird, adjusted the camera a bit, and made two exposures before he took off. Likely to get that one printed and framed: it’s a nice shot!

Planets and moons make a nice showing

A lovely waxing crescent Moon floats alongside planet Jupiter.

Earth’s Moon joined this spring’s conjunction of Jupiter and Venus in our western evening sky. The clouds cleared just in time for the show and I stepped outdoors, tripod-mounted camera in hand, to record the sight as best I could. The three objects, on the list of brightest in the night sky, formed a very elongated triangle with Jupiter and the Moon forming the base, and brilliant Venus at the peak. The three were visible in bright twilight but really came into their own around 8:30 EDT. Later, as I processed my photos, I was surprised and delighted to see I not had captured Venus, Jupiter, and the Moon but, in a tighter shot, a couple of Jupiter’s moons as well; they appear as tiny specks of light next to Jupiter’s small disk. The nighttime portion of the Moon’s face is lit by bluish Earthshine.

Sometimes a wrong turn is the best

Heron rookery in the Cuyahoga Valley National Park.

We were trying to make our way from Point A to Point B this afternoon when, somehow, I missed a turn. We wound up traveling south instead of north — pretty easy to do on unfamiliar roads and under overcast skies — and traveled quite a distance from where we wanted to be. We also didn’t spring for the navigation package for the Honda Insight; I don’t regret that, however. Since we had no schedule there was no pressure so, as we realized the mistake, we simply turned and headed north, carefree. As we drove we began to recognize some names of crossroads and knew that some would take us into the Cuyahoga Valley National Park and toward Peninsula. As we progressed along Bath Road we saw a group of people gathered along the side of the road, several of them crossing the road to stand along a fence; they were all looking at the trees. Oh yes! It’s the Heron rookery! Of course we stopped. I happened to have my little old Canon Digital Rebel XT with me so I shot photos as we watched the Great Blue Herons gliding down to the fields and lofting back up to the trees with twigs and branches. A birder I spoke with said the herons were nesting early this year because of the warmer weather. We were very lucky to happen across the scene and stood and enjoyed the activity for some time before continuing our trip. Sometimes a wrong turn is the best.

Deer move through morning ground fog.

While I generally don’t relish dragging myself out of bed early only to head off to work, some mornings are better than others. Recent changes in the weather made for beautiful scenes along my commuting routes yesterday and today. Golden sunlight filled dew-drenched grasses and weeds with diamonds. Ground fog lent a sense of soft mystery to this dawning day. And deer arrived with the morning.
