What Is a Telescope?
From Galileo Galilei to Albert Einstein to every other kid in your neighbourhood, stars never cease to fascinate people. Outer space is considered the future of the humanity. How many books and movies are created about mankind adventures out there! And while just setting out to such a journey is still a dream, we watch the Universe through the "eye" of our telescopes, the devices somewhat similar in construction to monoculars.
But telescopes, even the portable ones everyone can have at home, are so much more powerful. Today, this invention allows us to see not only a ship in the sea or a mountain far away but watch distant celestial bodies—by catching the light they emit and magnifying the image to fill the retina of our eyes. The science has gone far since the times of Copernicus, hasn't it?
If you or your kid ever dream of becoming an astronaut going for a space travel, a good overall fitness is a must. Start preparing right now with inversion tables and treadmills.
What Features to Compare
The modern telescope market has a wide selection to suit nearly every taste. The correct lens and mirror system are vital when making your choice. There are 5 mains systems to consider when choosing - a reflector, refractor, Cassegrain, Maksutov-Cassegrain, and Schmidt-Cassegrain, thus make sure to not overlook the optical surveillance system. An important thing to consider is the aperture size and the focal length of the telescope because these features predetermine the optical power of the product.
Next up, attention must be paid to an eyepiece and magnification. Selecting an eyepiece is a real headache for stargazers because there are lots of diverse products varying in schemes and design. The scheme of the eyepiece determines its maximal magnification capability.
There are three main types of adjustment (mount) systems in the world of amateur telescopes, which are azimuthal, equatorial and the Dobson system. Each type of adjustment system has its own benefits and downsides. For example, an azimuthal adjustment is not excessive, inexpensive and lightweight, but is incapable of precise astronomical photography. Equatorial adjustment is more excessive and weighs more, but is more accurate when compensating for the Earth’s rotation without computers and servo-motors.
Performance opportunities and ease of use give practical advice for easy maintenance. Also, different models offer different additions and special features which simplify handling and make it more enjoyable. As an example, some of the modern telescopes have a navigation system (GPS) which helps a user to find a defined object in a matter of minutes.
Celestron NexStar 130 SLT 31145
Number One Manufacturer
Looking for an amateur telescope, you will undoubtedly stumble upon the name Celestron pretty soon. The company has been around since the 1960s, although it had changed "hands" several times throughout the years. Nevertheless, Celestron today is a brand known and respected in amateur astronomy circles all over the world.
The SLT series is an upgrade from the Celestron's previous GT series. SLT stands for Star Locator Telescope. This family includes reflecting and refracting telescopes that offer improved performance, better mounts, and feature a new hand control.
The NexStar 130SLT is the latest addition to the Celestron telescopes' SLT family and the biggest reflecting telescope in it, making 130mm for the reflector (hence the 130SLT name). Being designed with observatory telescopes technology in mind, this Newtonian telescope offers one of the best light gathering abilities you'll find on the market, making it possible to locate planets, galaxies, nebulae, and bright twin stars even in deep space. You will open up the Universe anew with all its uncountable marvels.
The included hand controller offers several interesting features. For example, a Constellation Tour and the Identification. The database of celestial objects includes over 4,000 names, for the most popular of which there is expanded info. You can also add your own objects to the database and, when the time comes for an upgrade, you can suggest your objects to be added to the general database.
Any Eyepiece You Want
In the set with the NexStar 130SLT, you will receive two 1.25" eyepieces, a 25mm one with 26x magnification and a 9mm one with 72x one. However, the telescope is actually also compatible with the 2" eyepieces so if you want to upgrade to a wider field of view you can have it just like that. At the same time, note that the f/5 speed already offers a spectacular field of view, therefore, it is not really all that necessary to buy 2" eyepieces which are, by the way, more expensive than 1.25" ones.
All for Your Utmost Convenience
The new tripod designed for the SLT series of Celestron telescopes is more stable yet still quite lightweight steel one instead of aluminum. It has a tray where you can put anything you might need at the tips of your fingers, be it eyepieces or your smartphone. The Altazimuth mount with the SkyAlign alignment technology and StarPointer Finderscope makes aligning your telescope a cakewalk: simply find three bright points in the sky, locate your current position, and you are ready to explore the universe. The Saturn rings or Great Nebula in the Orion? Nothing could be easier.
Best Telescope for Astrophotography
The Gskyer EQ80900 is a 100% professional telescope for amateur astronomers and especially for astrophotographers. Every detail here is implemented for the best photos, from Equatorial mount, which will stay fixed on your chosen celestial object despite the Earth rotation, to a slow "speed" (or focal ratio) of f/11.25 that offers great magnification. The optical parts are made of glass, the lens coated with the multilayer green film that also adds to the image brightness and clarity.
The focal length of this scope is 900 mm, it will make the objects you look at appear bigger than a shorter product would. And the 3x Barlow lens, added to any of the three eyepieces that come in the box or to any of your other lenses, enhances the viewing power even more. With this telescope, high-power photography is a breeze, you will make pictures of the Moon, planets, and binary stars in the highest quality.
By the way, as this is a refracting telescope, you can use it for natural science photography just as well!
Reliable Assistance in Your Observations
The tripod in this model is made of stainless steel, it will stand sturdy and won't wobble or break easily. Granted, it may be a bit heavy for a kid but not too much, in our opinion. The installation takes next to no time at all and requires neither tools nor any special skills. You just follow the included manual. There is an attachment plate for the telescope. There, you can put the eyepieces you don't use at the moment as well as your smartphone or anything you might need at some moment of observation.
The telescope generally does not require any special maintenance.
Choose Your Magnification
The complete set you will obtain upon delivery includes the Gskyer telescope itself, a tripod with attachment plate, a manual, a wiping cloth, a Barlow lens, and three lenses of different sizes: 25 mm, 10 mm, and 5 mm. The 25 mm lens will offer 36x magnification, the 10 mm one—90x, and with the 5 mm lens you will see objects 180 times bigger than you would with a naked eye. This way, you have the opportunity to choose the magnification depending on what objects you are planning to observe. All three lenses have 99.5% light transmittance, providing you with a clear natural-looking image that will not cause stress or harm to your eyes.
Optical Surveillance System
Performance Opportunities and Ease of Use
The Seben company offers one of the fullest packages with their Star Commander 900-60 Refractor Telescope, and that's the first thing you notice when you check the description. There are 4 eyepieces in the box, a Barlow-lens, an erecting eyepiece, a Moon filter, a finder scope, a phone mount, protective caps for the tube and accessory socket, a tripod, an Azimuthal mount, and receptacles for the eyepieces. That's quite a set—everything you might need not only for celestial but also for terrestrial viewing, meaning you can observe animals and birds with the same device you watch the starry night sky, no need to pay for anything extra, it's all already in.
Make Memories Last
The Seben Star Commander 900-60 is a long telescope, its focal length is 900 mm, making the subjects of interest for you appear bigger. The finder scope will help you locate the stars and planets without hassle.
The scope also features a smartphone camera mount, meaning you can take photos of what you see in the scope just like that. And since the view is equally clear at night and during the day, you will have both celestial and terrestrial photos.
The Variety of Eyepieces for Every Purpose
There are as many as four regular eyepieces: 4 mm, 6 mm, 12.5 mm, and 20 mm. These will offer you four magnification options respectively: 225x, 150x, 72x, 45x. Throw in the Barlow lens together with each eyepiece and everything doubles, you now also have 450x, 300x, 144x, 90x. Eight options. That's a lot more than most scope manufacturers offer with the initial purchase package, you'll see somewhere around 11.5 million stars. But that's still not all.
The Moon filter will reduce the glare and enhance the contrast to show you more details like craters and seas on the surface that are usually somewhat smothered.
The INTEY F40070 is a fairly small and very portable telescope, its focal length is 400 mm and aperture is 70 mm (you can see it in the name). It's light in weight, a little over 2 kilos. You can easily take it along when you visit the countryside, go hiking or mountain climbing, or simply give your kid to carry to the friend's overnight pyjama party. It is, in fact, a great kids telescope, the best choice for their first model since it's not too costly and actually can give some more expensive models a run for their money.
Assembling this cute little guy takes five or so minutes. There is the telescope, its tripod, two eyepieces, a diagonal mirror, a finderscope. All parts are light and easy to manage. The mount has four adjustment angles and a directional adjustment up to 180° vertically and whole 360° horizontally, the latter is lockable. For clarification, the manufacturer has included a manual in several languages.
Convenience Above All
The telescope will come to you in an extremely handy rucksack. With pockets and straps inside, it has all the necessary space to safely store the scope and all its pieces when not in use or to carry along on a journey. It is also sturdy and simple-looking, so it can be used as a backpack where you'll put your other necessities when you travel and leave the scope at home assembled.
The height of the tripod can be set between 16" and 41" so you can stand or sit when you use it.
Up and Down
This kids telescope can be used to watch both sky and earth objects without restriction. Therefore, even if it ever happens that your little explorer outgrows the fascination with the starry sky, he or she can still use the scope to watch ships from the shore or animals in the field.
There are two eyepieces here, one is 6 mm with a magnifying of 67x, the other is 25 mm with the magnifying of 16x. The 25 mm with a 5x finder scope is recommended for finding your target; after that, you can lock it and switch to the 6 mm piece and watch the chosen object for more details. The diagonal mirror will return your target's image to how it should be—necessary since telescopes normally show the objects mirrored upside down and right to left. Note, though, that the diagonal mirrors only rearrange the image vertically, meaning that horizontally, you will still see it reversed. It takes some time getting used to it but usually does not pose an issue.
To protect your INTEY telescope between uses without disassembling it, use the included dew shield and dust cap. These two items will shield the lens from damage.
Q: What are these f/5, f/10 numbers?
A: They are called the focal ratio or also the "speed" of the telescope. Focal ratio is calculated by dividing the focal length by the aperture and in simple words, it shows how wide and bright the image you see will be. Faster focal ratios (those with lower numbers) have wider field and lower magnification, good for those users who are into deep space observation. Slower ratios are good to watch the Moon, planets and other big or relatively close objects.
Q: Do I need a Barlow lens?
A: That is up to you to decide. Barlow lenses magnify the image of the eyepieces, so, let's say, instead of buying three additional eyepieces with double the magnification of the three you already have, you can buy a single 2x Barlow lens and use it with each. Actually, using a Barlow will offer you a better quality image with less aberration.
Q: Is more magnification always better?
A: Not always, it normally depends on what you look at. When you have higher magnification, you simultaneously lose in the field of view and in brightness. Consequently, if the object you look at is already faint, high magnification will not help. To see faint objects clearer and to make them appear brighter, you need higher aperture. Also, at the higher aperture, you can also add magnification.
Q: Do I need all these many eyepieces?
A: Different eyepieces are good to observe different objects, so if you are buying a telescope for a single particular type of objects you might not need additional eyepieces but for anyone interested in astronomy in general, the more eyepieces usually the better.
Q: Reflector vs. refractor, which should I choose?
A: Again, this is subjective to your goals. Refractors provide more contrasting pictures than reflectors but a refractor with a big aperture for observing deep space would be extremely bulky and will cost an immense amount of money so they are usually better for planetary, lunar observation, and to watch really bright binary stars and nebulae. Reflectors have bigger apertures, thus they gather more light and allow you to see farther into space clearly.
