And if you need to travel light, you can leave the steel tripod at home, as the GoTo telescope can also be used on a sturdy table or other level surface.įeature-packed astronomy kit with practical accessories Thanks to its compact Cassegrain design, this telescope is easy to transport to your favourite stargazing spots. The best places for stargazing are rarely next to your front door – to see as much as possible, you’ll need to find a dark place with an unobstructed view of the sky. Practical GoTo telescope for on-the-go use The entry-level telescope also has a 90 mm aperture, which collects around 165 times more light than the human eye, allowing you to explore deep sky objects such as the M27 Dumbbell Nebula in the constellation of Vulpecula or the M57 Ring Nebula in the constellation of Lyra. Thanks to the two included eyepieces, you can choose between 50x and 100x magnification. Marvel at Jupiter’s clouds or Saturn’s rings – featuring a 1250 mm focal length, this astronomical telescope is perfect for taking a closer look at the large planets in our solar system. Choose from an amazing range of night sky objects and explore the wonders of the universe!įeature-packed telescope for beginner astronomers What’s more, the telescope tracks objects automatically via its two quiet motors in order to compensate for the earth’s rotation. From fascinating gas giants to bright deep-sky objects, you can use the practical handset to bring your target into view with a few simple button presses. It comes with an altazimuth GoTo mount, which allows you to align the telescope automatically with over 270,000 pre-programmed night sky objects. For more, you have to buy the better telescope.The NATIONAL GEOGRAPHIC Automatic 90 mm telescope is the perfect entry-level telescope for beginner astronomers. You see that you can do a lot with this telescope, but it won't be some spectacular sight and these are the only things you could observe. You could try also nebulae, for example M 57 in Lyra. Try Andromeda galaxy! It won't have some visible form, but it will be some cloud of brighter region. Also, you could look at the globular clusters with the smallest magnification. If you have budget for buying the solar filter (cheap ones for 10 dollars), you could point the telescope towards the sun, but beware! Don't mimic Galileo Galilei, who was observing the sunspots throught the telescope when the sun was low without solar filter! Check the page for sunspots. Even I couldn't see it never with my aperture of 250 mm.īut planets aren't everything. If Pluton is planet for you, it is far beyond the range of your scope. Neptun and Uranus are too dim to be observable with this telescope, but maybe you will be able to see them with some experience after 1 or 2 months (only like normal stars, maybe blueish). Mercury will be visible only as small dot. What about Venus? Maybe better than Mars, but just small Moon like form. Jupiter's disc will be seen with ease, but harder will be Mars just on peaceful nights. So what is the answer? You will be able to see the Moon and its mare and some craters, but also Saturn with his rings. Smaller picture is better, but not too small. But if you expand it to the whole screen, you would see only pixels and some form of A. When it is small like it is now, you can resolve the big letter A. Why? Look at the icon in the title bar of this Stack Exchange. Magnification of 117x won't be useful with planets. You should consider it only when observing near double stars. If you place the Barlow on the scope, the magnification is too high for the small aperture. You will be able to see main craters and mare on the Moon. With this setup, you can observe the disc of the Jupiter, but also the rings of the Saturn. I don't know how good the mirrors are, but I would recommend the setup with 6 mm eyepiece without a Barlow (= 58x). But this rule applies to telescopes with better optics. That means, that the optimal magnification is from 60x to 90x. The rule of a thumb is, that for optimal observing of the planets you set the magnification of 20x to 30x for every inch of the aperture. Possible magnifications: 18x, 36x, 58x, 117x. I see that you have correct data for the magnification.
