Product Information

Celestron Inspire 100azAimed at beginners and those looking to upgrade, this 4-inch refractor is at its best with the moon and planets and comes with a lens cap that converts to a clever smartphone holder for easy astrophotography.★★★★ The Unistellar eVscope 2 isn't like 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 114mm aperture and a focal ratio of f/3.9, it's very well-suited for observing celestial objects like nebulas and galaxies.

White’s role on the project was to help develop scientific instruments that could be attached to the outside of the balloon gondola to measure radiation exposure — and the larger team’s efforts were successful. The data they gathered showed that astronauts would be subjected to high-energy particles from solar flares, which could harm their bodies. In fact, a version of the suits worn by the Strato-Lab pilots would ultimately be chosen for NASA’s Mercury astronauts. 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.Telescopic magnification depends on the telescope's focal length (the distance between the objective lens/primary mirror and the point of focus of the light it collects) and the focal length of the eyepiece used. Magnification is calculated by dividing the telescope's focal length by the eyepiece's focal length. For example, a 100 mm telescope with a focal length of f/8 (eight times the telescope's aperture) has a focal length of 800 mm; used in conjunction with an eyepiece of 10 mm it will deliver a magnification of 80 times (800 divided by 10).

You see, NASA and its fledgling Mercury Program had put John Glenn in orbit just six months before Stargazer’s flight. And by the early 1970s, balloon-based experiments had given astronomers enough confidence to start launching artificial satellites with telescopes and other instruments into low-Earth orbit. But despite their best efforts, Project Stargazer lost funding, leading to the cancellation of all but one of the mission’s four planned crewed flights. And ultimately, that single flight marked the end of a brief era of high-altitude, crewed balloon flights. Celestron Omni XLT 102:A great option for intermediate users, it has good quality optics and a sturdy design, although we think the focuser could be better.★★★★ The Newtonian can be found on alt-azimuth mounts, but you shouldn't be too surprised to find this type of reflector is more popularly affixed to an equatorial mount, allowing the telescope to follow the rotation of the sky while being aligned with your hemisphere's celestial pole. This reflector is a favorite in the amateur astronomy community due to its versatility in observing a wide selection of astronomical targets and allowing for astrophotography. With Newtonians, you can also buy a large aperture for less money — for instance, an eight-inch (203.2 mm) reflector would cost you less than a refractor with the same aperture, allowing you to get much more value for your money.

Refraction

Regardless of your experience level, the Celestron NexStar 8SE is an outstanding motorized telescope. Beginners will love how easy it is to use, yet it's powerful enough to satisfy more experienced skywatchers and allow for deep space exploration and astrophotography.

If you're wanting to plan your next adventure, the telescope icon brings up a list of what will be visible in your location on any particular night. We also loved the app's 'stargazing index', which pulls together sunset time, moon phase and likely cloud cover into a percentage score of how likely you are to see anything on a given night — a very useful feature!One of the oldest forms of science is Astronomy. Stars and astronomy have served us pretty well over the ages. Be it navigating the seas with the help of the stars shining above, or the unveiling of various mysteries hidden amongst the stars; man has always been fascinated with stars and the universe above. The telescope itself is well-constructed and is very easy to use. Its 100mm aperture lets in a significant amount of light, allowing you to observe faint celestial objects like nebulas and galaxies. It also has a long focal length, providing substantial magnification and detailed views of planets and other nearby objects. Overall, we think the Celestron NexStar Evolution 9.25 is an excellent option for experienced and dedicated stargazers who are willing to invest in a premium GoTo telescope.

So if your biggest question is, 'which type of telescope type should I buy?' or 'what is the best telescope in the world?' let us help. What types of telescope are there?With a sea of products out there, it’s difficult for a person to wade through and find the telescope that is perfect in every respect. Fortunately for you, that’s where we jump in to help you. It is a tough task to look into every one of the telescopes to find out which the best is and which isn't. Magnification is one of the most commonly misunderstood features of a telescope. It does, as you might expect, make objects appear bigger in the sky. A 50x magnification telescope will make the 1/2° disc of the moon appear 25° in size. However, raw magnification power alone doesn’t result in a clear image. 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. Magnification is great if you know how to use it. 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. Telescope Eyepieces – Which Size is Right? If you have a bigger budget and want to invest in some real smart technology, we love the Unistellar eQuinox 2. It's the newest addition to Unistellar's lineup and stands as their most advanced smart telescope to date. Building upon the success of its predecessor, the eQuinox, this version features a number of improvements. While refractors use lenses, and reflectors make use of mirrors, to create and magnify an image, the catadioptric makes use of both lenses and mirrors for high-definition and superior views. During your observations, light from your chosen target passes through to a lens, which corrects or reduces aberration that distorts the view that is later taken in through the eyepiece. Curved primary mirrors then reflect this light onto a secondary mirror, which then reaches your eyes. You will find two kinds of Catadioptric telescopes — the Schmidt-Cassegrain and the Maksutov-Cassegrain.
