Catch All The Action With A Pan And Tilt Telescope
When you hear the word telescope, you tend to think of Galileo-wannabes ruining their eyes by staring up at the sky. Or perhaps you think of the crippled Jimmy Stewart watching his neighbors through the telescopic zoom of his camera in Rear Window. You can use pan and tilt telescopes for watching heavenly bodies, whether they are celestial or earthbound, but you can also use them for bird watching ("twitching"), nature watching, for photographing very distant subjects or for security purposes. Small pan and tilt telescopes mounted on rifles are frequently used in the military. All of these objects use pan and tilt telescope technology, sometimes called "pan-tilt" (astronomers call them alt-azimuth mounts). Knowing these pan and tilt telescopes exist can make you wonder if you're being watched by an unknown evil genius.

You Don't Have To Be An Evil Genius
Pan and tilt telescopes come in many sizes and prices for a variety of purposes. Most have to be set on a tripod or a stabilizing mount (for example a Dobsonian mount) of some sort. Some can be attached to cameras, web cams or other devices, while some are meant to be used by themselves. You usually have to manually adjust for focus, but there are some automated systems out there, although for the average person's budget, the manual will have to do.
Why is it called pan and tilt? Pan, usually short for panoramic, means "all" in its original Greek. All of what you want in your picture is what you get. To pan a camera or telescope is to move it around, usually so that the whole landscape or set or characters are in the shot. "Pan" helps you get the wide and comprehensive picture. Tilt is...well, it's just like what you think it is - tilting the 'scope up and down.

Goodnight Moon
Pan and tilt telescopes are still popular in their original guises as observers of the night sky. Even with a pan and tilt telescope costing under one hundred dollars, you can easily see Mars, Venus,comets and our closest neighbor, the moon. Some find it very relaxing to watch and chart these old friends. If it were not for amateur astronomers, the science of astronomy would not be so well developed today. You absolutely don't want to look at the sun through a telescope (you'll burn your eyes and be permanently blinded) whether its a pan and tilt telescope or any other kind of telescope, though. Pan and tilt telescopes, or just the pan-tilt mount to help your exiting lenses, are easily found in shops and online.
Pan And Tilt Telescopes News
September 2010
2 Sep 2010 at 10:30am Kinky. In this show we hear about theoretical cosmology and kinky vortons from Jonathan Pearson [12:00 - 28:128]. As always, Megan brings us the latest astronomical news [02:56 - 11:32] and we hear what can be seen in the September night sky in the northern hemisphere from Ian Morison [37:03 - 47:12] and in the southern hemisphere from John Field at the Carter Observatory [47:33 - 52:58].

The Superwind Galaxy NGC 4666
1 Sep 2010 at 3:00am The galaxy NGC 4666 takes pride of place at the centre of this new image, made in visible light with the Wide Field Imager on the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile. NGC 4666 is a remarkable galaxy with very vigorous star formation and an unusual ?superwind? of out-flowing gas. It had previously been observed in X-rays by the ESA XMM-Newton space telescope, and the image presented here was taken to allow further study of other objects detected in the earlier X-ray observations.

Richest Planetary System Discovered
24 Aug 2010 at 1:00am Astronomers using ESO?s world-leading HARPS instrument have discovered a planetary system containing at least five planets, orbiting the Sun-like star HD 10180. The researchers also have tantalising evidence that two other planets may be present, one of which would have the lowest mass ever found. This would make the system similar to our Solar System in terms of the number of planets (seven as compared to the Solar System?s eight planets). Furthermore, the team also found evidence that the distances of the planets from their star follow a regular pattern, as also seen in our Solar System.

How Much Mass Makes a Black Hole?
18 Aug 2010 at 3:00am Using ESO?s Very Large Telescope, European astronomers have for the first time demonstrated that a magnetar ? an unusual type of neutron star ? was formed from a star with at least 40 times as much mass as the Sun. The result presents great challenges to current theories of how stars evolve, as a star as massive as this was expected to become a black hole, not a magnetar. This now raises a fundamental question: just how massive does a star really have to be to become a black hole?

Ambitious Survey Spots Stellar Nurseries
11 Aug 2010 at 3:00am Astronomers scanning the skies as part of ESO?s VISTA Magellanic Cloud survey have now obtained a spectacular picture of the Tarantula Nebula in our neighbouring galaxy, the Large Magellanic Cloud. This panoramic near-infrared view captures the nebula itself in great detail as well as the rich surrounding area of sky. The image was obtained at the start of a very ambitious survey of our neighbouring galaxies, the Magellanic Clouds, and their environment.

August 2010
6 Aug 2010 at 2:34am O Canada. In the show this time we have two more interviews from Dave's visit to the University of Western Ontario. We hear about lunar geology from Dr Irene Antonenko [10:45 - 38:10] and Alex de Souza tells us about star formation [38:10 - 44:56]. As always, Megan brings us the latest astronomical news [01:41 - 10:16] and we hear what can be seen in the August night sky in the northern hemisphere from Ian Morison [50:16 - 62:05] and in the southern hemisphere from John Field at the Carter Observatory [62:13 - 66:40].

Seeing a Stellar Explosion in 3D
4 Aug 2010 at 3:00am Astronomers using ESO?s Very Large Telescope have for the first time obtained a three-dimensional view of the distribution of the innermost material expelled by a recently exploded star. The original blast was not only powerful, according to the new results. It was also more concentrated in one particular direction. This is a strong indication that the supernova must have been very turbulent, supporting the most recent computer models.
