Product Information

The Bresser Classic telescope features a 70mm aperture, with three eyepieces for sky viewing – 4mm, 12.5mm, and 20mm. It has an 18x-140x potential magnification and a 350mm focal length that enables a wide viewing area to be accessed through the tube. The 5×24 viewfinder has a hair cross design for easy and specific targeting. An erecting prism is also incorporated into the refractor design to create an upright, correct image for observation. You really should take some time to get to know what it is you will be gazing into, before you gaze into it using some fairly pricy equipment. mm aperture and 500 mm focal length, resulting in precise, high-resolution images for deep sky exploration. Equatorial mounts are not just difficult to use, they’re difficult to even comprehend at first. Simply trying to figure out how to orient the thing has killed the enthusiasm of many would-be astronomers. Optical Quality... The Slokey 40070 can reach a maximum magnification of 120x. The lenses are treated with an FMC ("Fully Multi Coated") coating and composed with a green layer that helps increase the brightness of celestial objects.

Optical Quality... The Slokey 50080 can reach a maximum magnification of 250x. The lenses are treated with an FMC ("Fully Multi Coated") coating and composed with a green layer that helps increase the brightness of celestial objects. This Schmidt-Cassegrain compound telescope features a 5-inch aperture, a 25mm eyepiece, an f/10 focal ratio, and its highest theoretical magnification is 295x. The sturdy steel tripod has an updated single fork arm design that is compact and works best placed on a steady surface. The entire Celestron NexStar set up can be disassembled for easier transport and weighs 28 lbs in total. The Slokey SkyWays 50080 is a bigger and better version of the SkyWays 40070 (see above). It’s aimed at beginner astronomers but is geared more towards adults than youngsters. The Slokey 40070 telescope has the right cost for the good quality it provides you. The telescope assembly is simple and easy for anyone with little or no prior knowledge. The instructions include illustrations at each step of the assembly to help clarify any text. The telescope body, accessories and tripod are lightweight and fit comfortably in the included case for easy transport. I’ll make an absolute statement here: An equatorial mount is a poor mount for a beginner. Later on, when your hobby has flourished, say you concentrate on planetary observing or have taken up astrophotography, you might happily consider paying tens of thousands of dollars for the best equatorial mount on the planet. But to start out with, equatorial mounts are simply awful. They’re difficult to set up, difficult to use, and the cheap ones are shakier than a leaf in a breeze.There are many styles of reflector telescopes but the most popular, and possibly the best reflector telescope, is the Newtonian reflector invented by Sir Isaac Newton. It features an eyepiece on the side of the scope which allows you to have a shorter mount. We told them to do the star test (compare the image just inside focus and just outside focus to see if they're the same), and also the "snap test": do the stars snap into tiny, bright sharpness at one exact focus point as you turn the knob, or do they shmoosh through focus a little more slowly and messily? And, to just look for the cleanest, sharpest stars. Anything below about 3 inches (76 mm) in aperture is likely to be too small to provide a pleasing view of anything more than the Moon and a few bright star clusters. Small scopes tend to be low-quality, too, with uncorrected objective lenses that display color fringing around bright objects and often won’t even come to sharp focus. So as a general rule, stay above three inches in aperture. There are, of course, some very high-end small scopes, mostly optimized for astrophotography. The price tag will tell you which is which. Most hobby killers will come with a 4-mm eyepiece, which is nearly useless on its own, but it will also come with a Barlow lens, which increases the magnification of whatever eyepiece you put into it. Most Barlows multiply by 2×, so your 4-mm eyepiece plus Barlow on that 900-mm scope gives you a whopping 450×, or (900/4) ×2. Remembering our 50× per inch rule, you would need a 9″ diameter telescope to use 450× effectively.

A telescope’s aperture is the size or diameter of the main or objective lens. Aperture is the most important feature to consider when buying a telescope. A larger aperture means a brighter image, better details and the ability to see deeper into the sky. 3. How to make a telescope more powerful? How to increase the magnification of a telescope? General guidance seems to be to use a magnification of 30 to 50 times the diameter in inches of your telescope's aperture. An aperture of 80mm is just over 3", so we are looking at magnifications of 90x to 150x. I guess, in closing, it's not necessarily the aperture that kills things for a beginner, it's the complexity. I buy and sell nearly constantly, helps me to get some excellent gear and I nearly always make money at it. I've sold some scopes with equatorial mounts since to new users, I made sure to go over how the mount works before taking money. So far, everyone seems happy. Great Entry-Level Telescope for Astronomy - Ideal for Adult Beginners to Start Observing the Universe - Great Quality and Power 20x-250x The Celestron Travel telescope features a 70mm aperture and comes with 10mm and 20mm eyepieces included, achieving either 20x or 40x magnification. Its highest theoretical magnification reaches 165x, its focal length is 400mm, and has a focal ratio of f/5.71. A 5×24 finder scope attaches to the side of the main scope. Plus, a top-rated astronomy software is also included to help you locate and view specific objects in the galaxy.Guess which kind you get with a hobby killer? Most of them come with “Huygens” eyepieces, which were state of the art when Christiaan Huygens invented them . . . in the 1660s. We’ve advanced a bit since then. You want at least Kellners, or better yet, Plössls. Plössl eyepieces are probably the best value you can get in an inexpensive eyepiece. Avoid scopes that use 0.965″ eyepieces. Left to right: 0.965″, 1¼″, and 2″ eyepieces.

Of course, the Celestron Travel Scope does have some room to grow and improve when it comes to the mount and the lenses but you can easily upgrade these components when and if you are ready to maximise the scope’s abilities. This clever scope is able to see clearly as far as Saturn, and can even show you the Crab Nebula M82 and M81Using a Barlow lens will increase the magnification, but it will also reduce the image quality and also the effective aperture, so the image will not be as bright and contrasty. I would suggest forgetting about the Barlow lens (at least initially), and just work your way up from the 25mm eyepiece to the 6mm. There is no point in using the 25mm eyepiece with the Barlow, since that will only give you 60x magnification, and trying to use the 6mm eyepiece with the Barlow is likely to prove frustrating, if not unworkable.
