King, Henry C. (1979). The history of the telescope. H. Spencer Jones. New York: Dover Publications. ISBN 0-486-23893-8. OCLC 6025190. Setting itself apart from traditional telescopes, this unique piece of kit uses its mobile app 'Singularity' to share captivating images of the night sky taken with its Sony image sensor rather than using an eyepiece. It's best used for capturing images of nebulas, galaxies and star clusters as it's not intended for viewing the moon or planets. Celestron NexStar 8SE:An outstanding telescope with incredible optics that would suit a beginner, intermediate or advanced astronomer. It's great for astrophotography and gives beautifully bright and detailed views. Our only fault with it is that it can price out beginners.★★★★½ Time to dispel jargon myths with a bit of a telescope glossary. The larger a telescope's aperture (the size of its main lens or primary mirror) the more light is collected and more fine detail is revealed. For example, a 200 mm aperture collects four times more light than a 100 mm telescope. Under ideal conditions, a 100 mm telescope reveals stars down to magnitude +11.8, while a 200 mm telescope will show stars down to magnitude +13.3. A 100 mm telescope will 'split' a double star separated by 1.5 arcseconds and resolves a three-kilometer lunar crater; however, a 200 mm telescope resolves a crater just 1.5 km across and a double star separated by just 0.6 arcseconds. Resolution is limited by the telescope's optical quality and the steadiness of the Earth's atmosphere.

The Maksutov-Cassegrain, also affectionately known as the 'Mak', corrects the optical problem that is experienced by reflectors — an aberration effect called 'coma,' which can make objects look distorted and appear like they have a tail. This effect is reduced or banished with the combined efforts of a spherical mirror and a meniscus lens, the latter of which is 'weakly negative'. The Maksutov is also adept at correcting for chromatic aberration, or color fringing, a distortion that creates an unwanted purple or blue edging around bright night-sky objects. The Skymax 150 weighs 13.23 lbs (6kg), making it suitable for most equatorial mounts. Many makes and models of mounts will be able to support the weight of the telescope, as well as any extra accessories you may want to use, such as CCD or DSLR cameras, filter wheels and other add-ons. For added versatility, the Skymax 150 comes with a Vixen-style dovetail plate, which can be attached to various mounts. You want to see planets and the moon:This telescope provides beautiful views of Saturn, Jupiter and the moon with stunning clarity. In our Celestron NexStar 8SE review, we walked you through what it's like to get everything set up, and it's very straightforward. No prior knowledge of the night sky is needed, as you can use Celestron's SkyPortal app or any other stargazing app to help you find two stars for the alignment process. Sabra, A.I.; Hogendijk, J.P. (2003). The Enterprise of Science in Islam: New Perspectives. MIT Press. pp.85–118. ISBN 978-0-262-19482-2.There are two common types of reflector telescope — the Newtonian and the Dobsonian. The way these instruments operate is the same — they both use mirrors to reflect light to create an image of the object you're looking at. Superbly sharp and bright thanks to the 8-inch aperture and powerful with a focal length of 2032mm, the NexStar 8SE sits atop a strong, sturdy motorized single fork arm mount which can be controlled via either the hand controller or through a computer by use of its ethernet connection. Telescopes may also be classified by location: ground telescope, space telescope, or flying telescope. They may also be classified by whether they are operated by professional astronomers or amateur astronomers. A vehicle or permanent campus containing one or more telescopes or other instruments is called an observatory.

Then it's just a case of tapping into the app to decide which celestial object should be viewed and the telescope will automatically slew to the target using an in-built motor in the fork arm mount. The Unistellar eVscope 2 is a step away from traditional telescopes, featuring a built-in camera, modern design and electronic eyepiece. It's the second version of the eVscope series and comes with noticeable improvements in its design and ease of use. With a 4.5-inch (114mm) reflector and a focal ratio of f/3.9, it's well-suited for observing celestial objects like nebulas. Sky-Watcher Skymax 127 SynScan AZ GoToA fantastic user-friendly scope ideal for anyone who wants a GoTo system but doesn't have a large budget to spend on a telescope. The tripod can be a little unsteady, but overall we think it's a great product.★★★★½ You want to see everything:While some telescopes are only good for seeing the moon & planets, or deep space, this telescope is good for seeing all types of celestial objects.

You're an experienced skywatcher:This telescope offers a complete tour of the universe, although its easy setup would be a dream for beginners, this scope is best suited for more advanced, passionate astronomers. The Orion Skyline 6-inch telescope is a fantastic choice for beginner and intermediate astronomers due to its easy-to-use nature and high-quality optics. The best telescopes will unveil the planets, stars and galaxies in the night sky. Whether you're hoping for views of the lunar surface, searching for planets like Saturn and Jupiter or you want a closer look at deep sky objects like the Andromeda galaxy. Additionally, it uses a planetarium to generate a 'tonight's best' list of different celestial targets and an algorithm to determine the optimum camera settings for viewing each target. Deși se indică cu termenul „telescop”, de obicei, telescopul optic, care operează în frecvențele luminii vizibile, există, de asemenea, telescoape sensibile la alte frecvențe ale spectrului electromagnetic.
