Greg Parker is a professor of electronics at Southampton University. He’s also a wizard. Like his co-author Noel Carboni. Real wizards, capable of obtaining some images that rival the best of Hubble’s and giant Earth-based telescopes using less than $15,000 in equipment and more patience than any money in the world could buy. Their magic: A refrigerated CCD chip, a rotating dome, and some smart post processing in Photoshop.
These images will be part of Star Vistas, a book that will be published next year and will collect all their photos of space, taken since they met online four years ago. The two alien Peeping Toms started to collaborate online in 2004. Neil—a Photoshop wizard with an astronomy inclination—helped Greg post-process his images of M33, which is a member of our local group of galaxies along with Andromeda (M31, who they also got in their book) and our very own Milky Way.

Greg uses a 28 cm Celestron NExtar 11 GPS reflecting telescope with Hyperstar lens, an optical assembly that attaches to the telescope secondary mirror, turning it from a slow f10 to an ultrafast f2 astrograph. This system is not designed for the human eye, so he got a matching Starlight Xpress SXV-H9C one-shot color CCD camera.
To increase the performance of the camera, he had to get rid of the noise in the sensor, which is produced by heat during long exposure times. This is achieved by installing a solid-state refrigeration system, which lowers the temperature of the CCD to 55º F less than the ambient temperature.
In addition to this, there is a last ingredient in the recipe: Parker moves the dome in his observatory by hand ever half hour, to adjust to the rotation of the Earth, which results in a moving sky.
In other words: Magic. [Star Vistas via Daily Mail]

Jon Hicks from Hicks Design has released the Helvetireader skin for Google Reader. Helvetireader takes a minimalist approach, masking many of Google Readers abilities, creating a simple and very easy to read interface to Google’s excellent RSS feed reader.Google Reader has been my RSS reader of choice since I made the switch from Bloglines […]

By allowing its snooty customers to manipulate the snooty Microsoft Surface interface with their snooty fingers, BMW has officially become the first car maker to offer the touchscreen tech to a worldwide car-buying audience. Impressed? Me neither, but that’s just because I’m a low-paid writer who’s insanely jealous of anyone driving a car that’s hotter than my 2006 Mercury Milan. So, basically everyone.
As you can see in the video, there’s nothing ground-breaking here, save for some fancy cars and interactive swatches for interior and exterior colors (the software was developed by Vectorform for BMW, btw). If you’re up for a stiff German guy reading off a cue card, though, then by all means clicky clicky. [BMW Blog, Thanks Haratiu!]

Is this tire really the “Holy Grail of Eco-Transportation,” as Treehugger believes? Maybe. Time will tell if the electric engine inside the Active Wheel from Michelin will catch on and further drive down the cost of electric vehicles. For now, let’s delve deep into this tire-motor combo, and you can decide for yourself if it has what it takes to kill the gas-guzzling combustion engine for good.
The wheels, while still in development over at Michelin, already have a vehicle ready to receive them. Called the Heuliez Will, this tiny tot from Opel doesn’t look like much, but it has it where it counts, and might produce an offspring that, in a galaxy far, far away, makes the Kessel Run in less than 12 parsecs. Or requires no gasoline to run. Probably the latter.
Even more impressive is the notion that in-wheel motors would free up space in the front or rear of the vehicle. This model also eliminates the need for other notorious space hogs like transmissions and exhaust systems. More room means more freedom for tomorrow’s automobile designers, and cooler cars for we consumers. (*fingers crossed* anyway).
The target price for the Opel right now is about $24,000-37,000, which puts it in line with the upcoming so-called savior of Detroit, the Chevy Volt. Testing on the Opel has already begun, with an official consumer roll out expected by 2011. Active Wheels are also expected to come standard on the Venturi Volage sometime in 2012.

| One of the most important developments in human civilisation was the practice of sustainable agriculture. But we were not the first - ants have been doing it for over 50 million years. Just as farming helped humans become a dominant species, it has also helped leaf-cutter ants become dominant herbivores, and one of the most successful social insects in nature. According to a recent study, leaf-cutter ants have developed a system to try and keep their gardens pest-free. |
