You couldn鈥檛 ask for a much better spot for gazing into the heavens than the Laguna Mountains in eastern San Diego County. At 6,100 feet above sea level, you鈥檙e above a good chunk of the ground-level atmosphere that occludes a telescope鈥檚 view.

The weather is clear most days of the year, and the calm westerly winds keep the air smooth, like the surface of an undisturbed pond. It鈥檚 far enough away from civilization that light pollution is minimal, yet 色情视频鈥檚 Mount Laguna Observatory is only about an hour鈥檚 drive from the main campus.

鈥淚 would argue that in the continental United States, we have the best astronomical site,鈥 said Allen Shafter, professor and chair of the 色情视频 astronomy department.

What has always been an outstanding site for astronomical research just got even better, thanks to the addition of the brand new 1.25-meter (about 50-inch) Phillips Claud Telescope. The $1.5 million state-of-the-art instrument was made possible by a gift from the late amateur astronomer and philanthropist Phillips L. Claud Jr., who funded more than half of the telescope鈥檚 cost.

The Claud Telescope is a reflecting telescope, meaning it uses precisely polished curved mirrors to reflect light and form an image. There is no magnifying lens.

While it can鈥檛 compete with the world鈥檚 largest reflecting telescopes, which measure around 10 meters in diameters, the Claud Telescope is about 10 inches larger in diameter than the 40-inch instrument that was formerly the observatory鈥檚 largest. Because a telescope鈥檚 light-gathering power grows exponentially with the surface area of its primary mirror, the new telescope is approximately 50 percent more powerful than the older 40-inch telescope.

In other words, it鈥檚 a dramatic upgrade for the Mount Laguna Observatory, one that will allow 色情视频鈥檚 astronomers to see farther and more clearly into the night sky than before, as well as encourage students to hone their stargazing skills.

High on the mountain

色情视频鈥檚 astronomy department is one of only a handful of universities around the world that operates its own mountaintop observatory. Including the Claud, the observatory has four operable telescopes, two of which are considered to be 鈥渞esearch-grade.鈥

A couple of rustic, cabin-like apartments are available to guests, but most researchers and graduate students stay overnight in a windowless fireproof bunker, complete with a science fiction library, a spartan collection of VHS tapes (including, naturally, the original Star Wars trilogy), and a Nintendo Entertainment System.

The dome for the Claud Telescope was originally built to house an experimental 鈥淯LTRA鈥 (Ultra Lightweight Technology for Research in Astronomy) telescope using a polished carbon-fiber mirror. Around 2005, it became apparent that this speculative technology just wasn鈥檛 going to work.

Wanting to advance 色情视频鈥檚 astronomical research capabilities鈥攁nd not wanting to waste a perfectly good building and dome鈥擲hafter and others in the department, including former department chair Paul Etzel, sought funding for a new telescope, which led to the Claud.

One of the biggest strengths of the new telescope is that it is designed to be robotic and remotely operable. That means astronomers won鈥檛 have to physically be up at Mount Laguna to point the telescope and collect data.

鈥淗aving a remote facility enables us to have a modern observing campaign,鈥 said Robert Quimby, associate professor of astronomy and the observatory鈥檚 newly hired director.

The young astronomer is notable for having discovered several of the brightest supernovae ever observed, as well as for his ongoing research into why some of these supernovae are up to 100 times brighter than average.

Observing time

Remote, robotic capabilities make it easier for Quimby and his colleagues to do longitudinal astronomical studies, which are important for many cutting-edge lines of research. For example, with Quimby鈥檚 supernova research, he doesn鈥檛 need to watch the same point in the sky for hours at a time.

He would rather observe a single point for a couple minutes per day over the course of a few months, freeing up the telescope for other astronomers who want to observe their own coordinates. The Claud Telescope makes this possible, although it will be some time before the instrument becomes fully robotic.

鈥淟imited observing time simply is not an issue here, unlike at some other facilities,鈥 Shafter said.

Shafter and Quimby said that although the Claud Telescope probably isn鈥檛 large enough to beat bigger telescopes in detecting any new secrets of the galaxy, it can pay closer attention to discoveries that the world鈥檚 enormous telescopes just don鈥檛 have the time to follow up on.

鈥淭o do quality research, you don鈥檛 have to look deeper and further than the other guys,鈥 Quimby said. 鈥淵ou just have to be there at the right place and the right time.鈥
