There was some excitement this dreary afternoon as this Cooper’s Hawk (Accipiter cooperii) first perched on a small tree in our front yard to stake out our bird feeder; then chased a couple of sparrows into a nearby row of barberries (seen here). This time the little birds escaped, rocketing out in separate directions at ground level from beneath the thicket and the predator. A pile of gray feathers beneath the bird feeder a couple of weeks ago were evidence that a Mourning Dove wasn’t so lucky as today’s sparrows. (Image shot though window glass and screen.)
A stroll in the Alderfer-Oenslager Wildlife Sanctuary at Wolf Creek Environmental Center led us out over the wetland area via boardwalk. Along the walkway was a late-season water lily bloom, floating on dark waters in the afternoon sun. Nearby, tiny green dots of plant life float. It was warm that day but cold days lie ahead. Nature knows.
On a walk today, I glanced down an alleyway and spied this scene: patio seating in a very grungy setting. The dreary skies softened lighting in an already-shaded area and amplified the mood of the al fresco table. I’ve ordered a replacement smart phone for my trusty iPhone SE that has served me so well so this may well be one of the last photos I shoot with its remarkable built-in camera.
I suppose one cannot return to something one hasn’t left. Still, with weather settling down and sunset coming earlier I’ve been looking to further explore the night sky.
We live in a small city with big light pollution. The light dome over our area has grown steadily over the past decade and from our backyard most northern stars lower than Polaris are completely obliterated by artificial light. To the south, the view is probably similar to “suburban” light pollution levels. Which is to say, bad but not impossible.
Lately I’ve been using my new telescope in imaging experiments. This week, unlike earlier recent efforts, I was able to get the telescope mount aligned well which allowed its computer to find dim objects in our bright sky. I was able to visually observe Jupiter (with Great Red Spot front and center), Saturn, the M15 star cluster, the Perseus Double Cluster, the Ring Nebula in Lyra, and the Andromeda Galaxy.
Attaching one of my DSLRs to the new Cassegrain reflector, I shot images of several of the larger deep sky objects. Vibration and tracking were issues, as was achieving camera focus. Working around those challenges as best I could, I made multiple images of the Ring Nebula (M57) and one of the clusters in the Perseus Double (NGC869).
Looking at the camera’s built-in LCD panel that night, I was astonished… I could see color in the Ring Nebula! Visual observers, using smallish telescopes, usually see no color in the Ring; film and electronic sensors readily collect enough photons to register color. Still, a very happy surprise to me! So I shot a series of prime focus images of the nebula. The Perseus Double was also visually attractive so I shot that as well. About 10 seconds for each of those. Efforts at shooting M15 failed: the telescope didn’t track well enough to produce round stars in the exposure time set — possibly too long an exposure.
Astrophotography of deep space objects can be extremely technical. The learning curve on an excellent product like PixInsight is more like a cliff than a curve. I searched and found a software that is excellent for me at my relative beginner level — Starry Sky Stacker (SSS). The SSS has the important basics for good astrophotography, and has an easy-to-learn image processing process with little frustration. So, to get started producing and learning, I used SSS to align, stack, and integrate the images for both NGC869 and M57 with results pleasing to me.
Over the coming weeks and longer, I’ll be assembling more equipment and skills and with luck, by spring, will be producing decent space pictures beyond the Sun and Moon.
Saturday night I spent imaging very large objects: Earth’s Moon and craters measuring nearly 60 miles in diameter. Sunday I photographed a lovely Tiger Swallowtail butterfly (Papilio glaucus) as it sampled nectar from a flowering plant; then, during editing, I cropped in close creating an image depicting an area of only an inch or so square on that insect’s wing. I do love exploring things from the very large to the very small.
Even smaller details, an unexpected bonus emerged in the cropped image. The swallowtail’s wing was at a severe angle to the morning’s sunlight enhancing the view of the individual scales that cover butterfly wings.
And yes, the butterfly was photographed alive and well, and left in that condition!
I was messing around with my recent soft-focused “antique” image of Moon’s Crater Tyco when I discovered a Photoshop sharpening feature I’d never used. I reprocessed the image using that setting and got a “better” result: sharper appearance of the crater itself but with more grain. I think I like this new one better than the one I originally posted. Here they both are: Reprocessed Above / Original Below.
I love shooting shelf clouds — clouds that form a line or arc along the leading edge of a gust front in a thunderstorm. They are awe-inspiring, scary, to me they’re just beautiful in their power rugged symmetry. I’ve looked at clouds from both sides now (apologies to Joni Mitchell) and discovered something at least as impressive; clouds of chaotic shards and pieces, tumultuously flowing together as a mass. I saw this configuration with a severe thunderstorm that dropped a tornado a few weeks ago, and I saw it again today in another severe thunderstorm — after the shelf cloud passed. I still love photographing shelf clouds (called “shelfies”, a twist on self-portrait “selfies”) but…
