I’m all bit up.
At the end of last week we had three or four days of cloudless skies and I got the urge to do some star-gazing. So I spent an hour or two each night in my backyard under the stars with my telescope. And billions and billions of bugs.
I was looking for this thing:

The Ring Nebula, M57, in the constellation Lyra.
Of course, that’s a photograph taken by the Hubble Space Telescope. It’s beautiful, but it’s nothing at all like what you see in real life.
Through a medium-size (12”) amateur telescope the Ring Nebula looks like this:

So-called “planetary” nebula like the Ring Nebula actually are colorful. They are made of gas near a star and, typically, ultraviolet energy from the star causes the gas to glow, something like the gas in a neon sign glows. But nebula are so far away that the light is very weak by the time it gets to Earth. There’s not enough energy there to ‘activate’ the color sensors in our eyes, so even through large telescopes we—typically—see nebula as white, or white with just a tint of color.
Of course, many amateur astronomers devote lots of money and uncounted hours to taking time-exposure pictures of nebula to capture the beautiful colors.
But even through small telescopes the ‘simple’ white images are amazing.
Some people have reported seeing the Ring Nebula in good 10x50 binoculars. I’m guessing they were under perfect skies and the binoculars were either solidly mounted on a tripod or new, image-stabilized binoculars. I’ve never managed to see the Ring Nebula through my 10x50 binoculars, but I’ve never checked under good skies.
Here south of Chicago even our best nights are pretty bad. Unimaginable (to rural folks) light pollution and almost constant haze.
Last week was a good example. We had cloudless skies, but the seeing was terrible. There was some kind of haze or smog from horizon to horizon. I could see Vega and Arcturus as naked eye stars. But they are two of the brightest stars in the sky. Almost everything else required binoculars. Even the Big Dipper was almost impossible to see by eye.
Jupiter is in Scorpius, to the south, and Antares—also one of the brightest stars in the sky—was just barely visible without binoculars.
Since Vega was visible, I decided to give my small telescope a work-out and see if I could view the Ring Nebula.
My telescope is a small refractor, a 2.4 inch (60mm) Unitron on an altazimuth mount. The focal length is 900mm. That’s f/15—not fast, not a wide field of view, and with a small objective, not great at gathering light for higher powers. But it’s a well-made scope with a rock-solid mount. Unitron made good optics. If you think of a scope like this sort of as half of really great binoculars, it sets your expectations to a reasonable level. You keep the power low and you get reasonably wide fields of view (for a telescope) and dark backgrounds and bright images.
I did most of my observing last week with eyepieces that were 25mm, 20mm and 18mm, for powers of 36x, 48x and 50x. I now and then checked things with up to a 9mm eyepiece for 100x, but under poor skies high power just magnifies the glare.
Because Lyra is almost overhead this time of year, I spent most of my time in the dark kneeling in the grass, or just sitting on the sidewalk next to my lawn. A Newtonian reflector lets you stand up to observe because the eyepiece is opposite the scope’s mirror. A refractor has the lens up front and the eyepiece at the ‘bottom’ of the tube. Even with a right-angle adaptor you still have to be willing, with a refractor, to get into weird positions to accommodate the scope. And, under bad skies, it’s always a good idea to keep the light path straight, so I was doing my observing without a right-angle adaptor.
The bugs in my backyard apparently were thinking, ‘Cool, an all-you-can-eat buffet!’
Lyra is a fun constellation because Vega is always easy to find, and there really are only five other stars to know. The stars make up a simple triangle-on-top-of-a-rectangle shape most binoculars can take in with very little ‘sweeping’ necessary. My wide-angle 10x50s can show the entire top or entire bottom of the constellation at once.The Ring Nebula is easy to find because it is between the ‘botttom’ two stars of the lower ‘rectangle’ of Lyra. In fact, there is a sequence of dim stars you can ‘hop’ along with a narrow view telescope like mine and M57, the Ring Nebula, falls just between them and off to one side. With a ‘normal’ amateur scope—a 6” or 8” scope—the Ring Nebula is easy to see and can be impressive even at high powers.
Last week I did not quite see it. The seeing was too bad, the skies were too poor.
I could just barely see the dim stars between β Lyra (Sheliak) and γ Lyra (Sulafat). Using averted vision—looking off center at the eyepiece field of view—I could make out a white ‘smudge’ where I knew the Ring Nebula was, but I couldn’t make out any structure at all.
But the summer isn’t over. We’ll have better nights.
I’ll see it. If I can survive the bugs.




Rembrandt often reverse such thinking. The brightest part of a Rembrandt painting might be lighting shining on somebody’s shirt cuff to the side of the composition. Shadows often engulf the actual features of a person’s face, the very subject of the painting is typically half-lost in darkness. An image of grays and browns might appear sparkling with colors only to be seen upon examination to have just one or two patches of pure color. Yet the overall effect of a Rembrandt image is often so powerful a viewer gets the impression that Rembrandt has somehow magically reversed cause-and-effect, a viewer gets the impression that Rembrandt has somehow twisted painting techniques which should confuse an image and forced those techniques somehow to actually clarify the image.
What better articulation of Rembrandtian color can we find than the Self-Portrait with Maulstick, Palette, and Brushes (c. 1663), painted some six years before his death? Convention focuses on the enormous expressivity of the artist’s careworn face. But what is there on the palette cradled in one arm? Nothing but a bare expanse of ruddy brown, so loosely sketched that the dark coat remains visible beneath. And one can almost believe that no more color than this, deftly lightened and darkened, was needed to convey all the introspection, the frankness, and the gravity that the portrait reveals.

“Yesterday I saw a large photograph of a Rembrandt that I hadn’t known, and it struck me very deeply: it was the head of a woman, the light was falling on her bust, neck, head, on the point of her nose and on her jaw. He forehead and eyes were in shadow because of her large hat, with feathers most likely red. Perhaps there is also red in her low-necked jacket. A dark background. The expression is the same mysterious smile of Rembrandt found in his self-portrait in which he is seated with Saskia on his knees, and a glass of wine in his hand. These days my thoughts are continually turning to Rembrandt and Frans Hals, not only because I am seeing many of their pictures, but because among the people here I see many types that remind me of their time. I am still going often to those popular dances, to see the heads of women of the sailors and soldiers. ... I know that you are rather convinced of the importance of being realistic, so I can speak to you freely. If I paint farmers, I want them to be farmers; ... if I paint prostitutes, I want that they have a prostitute’s expression. It is for this that the head of one of Rembrandt’s prostitutes struck me so much. Because he grasped their mysterious smile in such a marvelous way, with an earnestness that only he, wizard among wizards, possessed.”



The third candidate, and Wolfgang's reputed favourite, is his blonde-haired, denim jacket wearing 29-year-old daughter, Katharina. "It is a huge ambition for me," she said backstage at Bayreuth just days before the festival starts.

NEW YORK (Reuters) -- Battery and razor maker Energizer Holdings Inc. said Thursday it would buy Playtex Products Inc. in an all-cash deal worth about $1.2 billion to grow Energizer's personal care product range.
Procter & Gamble owns Duracell and Gillette which compete against Energizer's namesake batteries and Schick razors. Procter & Gamble also own the tampon brand Tampax which competes against Playtex's namesake tampon brand.
Energizer said the deal will boost its fiscal 2008 results and it expects to the deal to close in the fall of 2007. The company plans to finance the acquisition through cash and credit facilities.
