The Moon. You will notice that they are strung out in a line on either side of the planet. Found inside – Page 8These formulae are: Magnification = Telescope focal length/Eyepiece focal length Exit pupil = Telescope aperture/Magnification True field of view = Apparent field of view/Magnification Just remember that one inch equals 2.5cm or 25mm ... For close-ups of the planets, a modified webcam like Celestron's NexImage is a good choice OK, so you've put your hands on a decent starter telescope.

What can be seen with a 20-inch telescope? If you're on a rush, however, you can always settle for a 1.25-inch eyepiece. Smaller apertures have some benefits – they’re much more affordable, for one thing – but you may need to set your telescope up away from street lights to view distant celestial objects. You get great value for money in these quality Cassegrain telescopes. temperature. Of course, with this telescope, you can see outstanding detail when viewing the moon and you can see the Rings of Saturn and the Moons of Jupiter. a 25mm eyepiece used on a telescope with a 1000mm focal length would yield a power of 40x (1000 / 25 = 40) and a 10mm eyepiece used on the same telescope would yield a power of 100x (1000 / 10 = 100). What can you expect to see. High-quality lenses can bend the light more, offering a closer-looking, clearer image. The rings of Pleiades and double cluster in Perseus being a couple of my favorites. sits ready to perform, mounted to the tripod. I have a telescope with a 9.25 inch mirror, Through an average home telescope, Mercury and Venus can be seen, and you can see their phases (planets, just like our moon, go through phases where they show as a crescent shape).

At least a couple of cloud bands can be seen on Bring distant planets, nebulae, vast clouds of interstellar gas and clusters of stars into clear view, or just view the billions of years of history etched into our moon’s surface in stunning clarity. Then came improved eyepieces. Orion 8850 2-Inch Refractor Telescope Mirror Diagonal $84. Binoculars have an advantage because they provide low power (compared to a telescope) which means a much wider field of view – you can fit larger objects within the space of what you see. And believe it or not, some details on Mars can be seen with this With this scope, you can see more detail in objects like galaxies and nebulae than ever before! The 20-inch Obsession telescope. The StarBlast 6 is a powerful telescope for viewing deep-sky stars, planets, and moon. It can examine closer objects, such as the moon or a cloud formation, in finer detail and, if you have a telescope with a long focal length, it can bring distant galaxies and star clusters into pin-sharp clarity. One of the most wondrous sights you can expect to see on a clear night is Orion’s Nebula. If you want to see small and faint galaxies, globular clusters, and faint stars, there is no substitute for aperture. images a small, quality refractor can deliver is a joy in and of itself.

If you know what you’re looking for, browse the models above and pick the one you like the most. The Moon is the Earth’s only satellite and a wonderful object for observation. Shorter focal lengths provide a more magnified image with a narrower field of view. Aperture is far more useful than high magnification when it comes to viewing these distant wonders. 1-800-422-7876. This should answer your question on what is a 2x Barlow lens. 25mm and 10mm Sirius Plossl 1.25″ telescope eyepieces, The magnification is the telescope focal length divided by the eyepiece focal length, in millimeters.

Call us from 9am-5pm Monday-Friday on 0800 091 3171. In other words, the best magnification for you will be the one that lets you observe the objects in the night sky you want and at the level of detail you want to see them. The included 25 mm Plossl eyepiece provides 48x magnification with this telescope. The eyepiece with the longer focal length say 25mm (low power) used on a telescope with a 1000mm focal length will produce a magnification of 1000 ÷ 25 = 40x. Years ago, big heavy mirrors and long focal ratios were the rule. Put the … Without quality lenses, or the right aperture or focal length (we’ll explain these shortly), excessive magnification results in distant objects looking muddy and grainy. If you have a high-end telescope, you can expect the star to look like a shining ball. Galaxies. Actually, it is a good telescope to see planets. You’re still at the mercy of the Earth’s weather and atmospheric conditions, no matter where you go. They worked page. For example, the Stargazer Pro Telescope includes 10mm and 25mm eyepieces (as well as a Barlow lens, which we’ll get to shortly). A note on magnification: Many new astronomers fall into the more power trap, but that urge should be ignored when first learning astronomy. As you can see, the longer the telescope focal length and the shorter the eyepiece focal length, the higher the magnification achieved. With this feature you're going to get a better imaging effect when you use it. Poor seeing doesn’t necessarily mean a stargazing session is over, but it can make it difficult to see distant, fainter objects in the sky.
