With steady observations, Venus' phases and Saturn's rings can be seen along with high-definition sights of craters and lunar mountains. Good views of the brighter deep-sky objects can be had, too — the Andromeda Galaxy Messier 31 and Bode's Galaxy Messier 81 are stunning, with a pleasing amount of detail. A slight degree of color fringing, or chromatic aberration, can be seen around particularly luminous treasures, but this does not spoil the observations.
Related: Read our review of the Celestron Astro Fi Akin to the FirstScope and FunScope, this pleasantly painted telescope is already assembled out of the box, making it perfect for kids who want to get stuck straight into observing what the universe has to offer. The Orion StarBlast 4. With the supplied accessories, skywatchers can achieve magnifications of 76x and 26x. Yet with useful optical limits of 16x and x, the StarBlast 4. A comprehensive manual is included, however we feel that kids will find using this small telescope intuitive enough without it.
Weighing in at 13 lbs. We detected no stiffness in slewing from left to right or up and down, while the mount supported the tube adequately. With the supplied eyepieces, the entirety of the moon's disk fills the field of view. While it's not possible to get incredibly close to the craters, mare, rilles or lunar mountains using the included accessories, the Orion StarBlast 4.
The parabolic mirror ensures pin-sharp views, while the rack-and-pinion focuser smoothly brought the lunar surface into focus reasonably well for a beginner's instrument.
Views of the planets are fair, and as suspected, quite small through the field of view, while swathes of rich starfields are a stunning sight under good to moderate seeing conditions. We recommend purchasing a Barlow lens along with a selection of eyepieces to make the most of the telescope's optical system. The Celestron AstroMaster 70AZ is a no-frills telescope that makes a good starter instrument for skywatchers aged seven years and up — particularly those who prefer not to stoop down to use a tabletop telescope.
Some youngsters will need to be supervised while using the AstroMaster 70AZ. Like many starter scopes, the AstroMaster 70AZ doesn't require any tools for settiing up and comes with everything the skywatcher needs to kick-start a rewarding hobby, including 10 mm and 20 mm eyepieces, an erect star diagonal as well as a battery-operated red dot finderscope.
A download of Starry Night Basic software is also included and features a database of 36, targets to explore, including printable sky maps, three-dimensional renderings of galaxies, exoplanets and stars. Whichever way skywatching pans out for your young astronomer — whether it's a passing phase or a lifelong passion — this refractor is a great option that doesn't break the bank. There are more plastic features on the AstroMaster 70AZ than we'd like the star diagonal feels particularly cheap , but given the low cost and good overall build, the telescope will last for many observation sessions to come — provided it's treated with care.
It'll be able to withstand a few knocks, but be wary of giving this instrument to youngsters who are unlikely to respect the delicate optics. The steel tripod can be adjusted to suit a majority of heights for a comfortable observing experience, while the optical tube assembly provide good magnified views of the solar system, star clusters and bright naked-eye nebulas like the Orion Nebula Messier During our handling of this telescope, we are pleased to find that the alt-azimuth control operates smoothly, with no stiffness.
And, when the time came to lock onto a chosen target, the pan handle tightens sufficiently to prevent any sagging of the tube. A feature that ensures young skywatchers can take in the views without the need to continually re-adjust the positioning. Thanks to the multi-coated optics, we achieved bright, clear views of the moon, Jupiter and Venus: with sufficient fine tuning of the focuser, we are able to bring craters, the Jovian moons, a hint of Jupiter's cloud bands and a Venusian phase into clear view.
With most beginner refractors there is a degree of color fringing, where a purple-blue tint appears around particularly bright targets, but the observations are not spoiled. Given the telescope's 2. We recommend looking to invest in a selection of eyepieces to show your young skywatcher more dazzling sights of the universe.

Lowest useful magnification: 15x. Supplied eyepieces: 6. The curved mirror in a telescope is like a spoon: It flips the image. Luckily, the solution is simple. We just use other mirrors to flip it back. A simple reflecting telescope uses mirrors to help us see faraway objects.
Since they are much lighter than lenses, mirrors are a lot easier to launch into space. Space telescopes such as the Hubble Space Telescope and the Spitzer Space Telescope have allowed us to capture views of galaxies and nebulas far away from our own solar system. Set to launch in December , the James Webb Space Telescope is the largest, most powerful space telescope ever built.
It will allow scientists to look at what our universe was like about million years after the Big Bang. Dubner University of Buenos Aires. How Do Telescopes Work? The Short Answer:. Early telescopes focused light using pieces of curved, clear glass, called lenses.
However, most telescopes today use curved mirrors to gather light from the night sky. The shape of the mirror or lens in a telescope concentrates light. That light is what we see when we look into a telescope.

The "onion" dome at the Royal Observatory, Greenwich housing a inch refracting telescope with a remaining segment of William Herschel 's centimetre 47 in diameter reflecting telescope called the "foot telescope" due to its focal length in the foreground. The primary mirror assembly of James Webb Space Telescope under construction. This is a segmented mirror and its coated with Gold to reflect orange-red visible light, through near-infrared to the mid-infrared.
Modern telescopes typically use CCDs instead of film for recording images. This is the sensor array in the Kepler spacecraft. The Compton Gamma Ray Observatory is released into orbit by the Space Shutte in , and it would operate until the year The reflectors of HEGRA detect flashes of light in the atmosphere, thus detecting high energy particles. Six views of the Crab nebula supernova remnant, viewed at different wavelengths of light by various telescopes. Telescope facts for kids Kids Encyclopedia Facts.
