KentuckyFC writes "Liquid mirror Telescopes start life as a puddle of mercury in a bowl. Set the bowl spinning and the mercury spreads out in a thin film giving the surface an almost perfect mirror finish. But these Telescopes have two important limitations. First, they can only point straight up since tilting the mirror spills the mercury. And second, they cannot be made adaptive to correct for any blurring introduced by the Earth's atmosphere. But liquid mirror Telescopes look set for an upgrade thanks to the work of a group of Canadian researchers. Their technique is to change the shape of the liquid mirror using powerful electromagnets. They use a ferromagnetic fluid of iron nanoparticles in oil instead of mercury which is too dense to be easily manipulated in this way. The work is just proof of principle at this stage but the idea is to use magnets to correct for the usual range of optical aberrations that Telescopes have to deal with (abstract). And also to allow a liquid telescope to be tilted by using oil that is much more viscous than mercury and correcting any periodic deformation in the fluid that tilting might cause."

When Galileo made his telescope, he was far from the expert he became later He was just a layman, who found the sky and its stars fascinating and wanted a device that would take him closer to the object of his fascination It was this desire that led him o devise the first ever telescope that changed the face of history in more ways than we can imagine... ...

The first thing to keep in mind when you’re making a telescope by hand, on your own, is to know exactly how it functions The basic objective of a telescope is to magnify an object that is at a distance and make it appear much closer than it actually is, by bringing its image at the focal distance of the viewing lens You can learn all you need to know about the method of do-it-yourself telescope constructions through various mediums... ...

... who wants to construct his telescope at home, there are several viable options. One way to go about constructing a telescope is to buy each individual component and then assemble the whole structure. The required elements are mirrors, concave and convex lenses, the housing structure, brackets, and some other components. These can all be bought at local shops or in online stores. A comprehensive list of required elements can be downloaded from websites that serve as guides for amateurs looking to build their own Telescopes. Books dedicated to this subject are available. An enthusiast may... ...
