Compact and lightweight refractor that can be easily carried in one hand. The first thing that catches your eye is the colorful original packaging, which not only attracts attention, but also makes you want to get acquainted with its contents as soon as possible. Say what you like, but the telescope can be considered the eighth wonder of the world, because only it is able to please us with beautiful pictures of the starry sky and reveal the secrets of distant constellations and galaxies.

In the presence of a case or cover, such a telescope can be transported even in public transport, since its dimensions in the disassembled state are comparable to the size of a tripod and do not exceed 80 cm. Levenhuk Strike 80NG into a universal telescope suitable for terrestrial observations. Watching barges, yachts, fish in it is a pleasure. Therefore, you can take the telescope with you, going on vacation even in the daytime - there will always be a use for it. This telescope is the eldest in the family LevenhukStrike, which includes two more junior models, and has excellent image quality.

The telescope tube is painted in a classic white color, which during the daytime does not allow it to get very hot in the sun, and at night it does not get lost against the background of the landscape. In the moonlight, the trumpet sparkles in the dark, drawing the observer's attention and inviting them on a breathtaking walk through the starry sky.

Some photos LevenhukStrike 80NG.

The build quality of the telescope is not satisfactory. The tube is made carefully, immediately after assembly the telescope gives the impression of a reliable and convenient optical instrument. The Red Dot Finder, or "Starpointer" (also known as "Red Dot"), is very convenient to use and allows you to quickly and easily aim at the desired object. Before starting observations, do not forget to align it with the telescope tube in order to correctly aim at objects. The focuser is made of hard plastic, has a soft stroke, no backlash.

The "Starpointer" ("Red Dot") finder produces a bright red dot.

The telescope is mounted on a Yoke alt-azimuth mount, which lightens the weight of the entire set and simplifies control.

The lens hood reliably protects the lens from shock and dew.

Installation on a tripod takes no more than 30 seconds. The tripod itself is lightweight, while the main components are made reliably.

In addition to the eyepieces, which will be discussed a little lower, the set includes a focal length extension - a Barlow lens. In the photo below you see one of the mounting options for the inverting prism, eyepiece and Barlow lens.

And, of course, it should be noted a large number of reference material that comes with the telescope. A planetarium program, a book for novice astronomers “See Everything!”, a planisphere, an instruction manual, plus such an indispensable thing in astronomy as a compass (with its help, the telescope is set in azimuth to observe the risings of the moon and planets) will allow you to quickly master the control Levenhuk Strike 80NG. And by purchasing necessary knowledge for further exploration of space, go already to a large aperture.

The tripod unfolds and is fixed with a tray for accessories, which is very convenient for observations, hands do not get confused. We install the compass directly on the tripod spider and orient the telescope in azimuth to the moonrise point calculated in the Stellarium program.

As stated above, LevenhukStrike 80NG belongs to the “light” series, which includes two more telescopes designed as portable and simple instruments for observing the starry sky. All of them differ slightly in weight and resolution, the latter is related to the angle at which the celestial body is seen.

Levenhuk Strike 80 NG telescope test

The test scheme is shown in the figure below. As an artificial star, a point removed at an appropriate distance, with a diameter of 10 microns, illuminated by a white LED, is used.

The point is to view the resulting image through a strong eyepiece, that is, to use magnifications from 1,4 D.At the output, we have an image burdened with various aberrations, and so in any optical system. The test uses an ocular projection. The image is recorded using a canon 350D camera, with a focus of 55mm.

Types of out-of-focus lenses and focal points are shown below.

As you can see from the test, the dot is pretty decent, although some astigmatism and spherical aberrations are present. Aberrations worsen the image, not allowing you to set high magnifications. This does not apply to this instance. Since the telescope allows you to attach reflex camera, it turned out to conduct an additional test.

As expected, at the edge of the field, the point is distorted by aberrations, but it is quite suitable for shooting in focus.

LevenhukStrike 80NG has high quality images, and it can be recommended not only to beginners, but also to self-confident users.

Shooting terrestrial objects and the moon

For photographing astronomical and terrestrial objects to LevenhukStrike 80NG you will need to purchase additional accessories.

In this shooting, a "glass" from a two-time metal Barlow lens was used (the lens must first be turned out) and an adapter T-ring from M42 to canon EOS. Installation and landing in the photos below.

Do not forget that the telescope has a plastic focuser, so you should not give excessive load. Canon cameras thousand series (350d, 400d, 500d, 1000d ...) work with the focuser to the limit. 2" eyepieces are not recommended.

as the stem increases, plus, due to their considerable weight, they can easily deform the focuser tube.

The shooting itself is carried out in the “M” mode with a timer release to dampen the vibrations of the pipe. Below is a shot in focus LevenhukStrike 80NG, in the upper corner of which a fragment of the same image is inserted, but at a focus of 55mm for comparison.

The moon is filmed in the same way. The use of the astro camera for this telescope is limited because an equatorial mount is required.

Brief conclusions

Certainly, telescopeLevenhukStrike 80NG is the initial basic setup for transitioning to other aperture (with a large lens diameter) instruments. But, in order to put your hands and not get confused in a more complex model of a telescope, it will fit just right. Lightweight, stylish, not bulky, with a great design, the telescope will immediately fit into the interior of your apartment or cottage. You can always take it somewhere with you as a tool for surveying the surroundings, of course, without forgetting about its main purpose - observing the starry sky, which will give you many hours of great rest while discovering more and more new treasures of our Universe.

And in conclusion, a couple of views of the moon with LevenhukStrike 80NG.

LevenhukStrike 80NG- a great choice to start your passion for astrophotography.

Useful information for beginners

The purpose of any telescope is to increase the angle at which a celestial body is visible, and to collect as many rays of light coming from it as possible. The principle of operation of the telescope is quite simple: the image of a distant object built by the lens is viewed through the eyepiece. By changing the eyepieces, we change the magnification in the system. Because the LevenhukStrike 80NG primarily intended for beginner astronomy enthusiasts, first we will focus on simple formulas that everyone uses to determine the magnification, the field of view of the telescope, and the calculation of the exit pupil. In the future, when buying new models, this will allow you to choose additional eyepieces.

The formula for determining magnification is as follows:

M=F/f, Where

F- focal length of the lens;

f- focal length of the eyepiece.

TO levenhukstrike 80NG The standard delivery includes two Kelner eyepieces - 6mm, 20mm. Substituting these values ​​into the formula, we get: M1= 720mm/20mm= 36x,M2=720mm/6mm= 120x.

In addition to the eyepieces, the set includes a 3rd Barlow lens,

which triples the focal length of the lens, creating two additional magnifications: M3=108x,M4=360x.

The field of view of the telescope G) is calculated as follows:

G(arc min) = 60*W/M, Where

W- subjective eyepiece field of view (40 degrees for Kellner)

M- magnification of the telescope created by this eyepiece.

Thus, we obtain the corresponding fields of view

G1\u003d 67 arc minutes for a 20mm eyepiece,

G2= 20 minutes of arc for 6mm eyepiece,

G3= 22 arcminutes for 20mm eyepiece and 3x Barlow lens,

G4= 7 arcminutes for 6mm eyepiece and 3x Barlow lens.

Consider circuit diagram telescope on which LevenhukStrike 80NG.

At the exit from the eyepiece we have a narrow beam of rays with a diameter d, the so-called exit pupil. Its value must be known, since in the literature, to observe one or another type of object, it is often indicated not the magnification of the system, but the diameter of the exit pupil

within the specified range. This is due to the fact that the magnification of the system depends on the focal lengths of the lens and the eyepiece and is a relative value, while the diameter of the exit pupil is absolute. It is known that the pupil of the eye in the dark has a diameter of 6-7 mm, and in order to collect all the light with LevenhukStrike 50NG, we need to use the smallest increase, which for this model is 35x. Calculate the diameter of the exit pupil using the formula:

D/d=F/f=36 ,d=80/36=2.2mm.

It can be seen that the diameter of the beam of light emerging from the eyepiece falls on the pupil of the eye, while covering the field of just a degree ( G1=67).

Example 1 - Orion Nebula (M42)

In the materials for the telescope you will find an excellent reference book by A.A. Shimbalev for beginners and a moving map of the starry sky. For example, under No. 125 it lists the Orion Nebula (M42). Its dimensions (1 degree) and magnitude are indicated. It is clear that for a comfortable observation of such an object, you need to choose an eyepiece in which it will fit the nebula completely. We look at our table, calculated above. We see one of the suitable calculations: G1=67,M1=36,f=20mm.

Example 2 - globular star cluster in Hercules

Consider another example, #85 - the globular star cluster in Hercules. Angular diameter - 23 minutes, brightness - 5.8m.

To begin with, to find it, we put the weakest eyepiece with f=20mm. Then, using the table, we change it to a 6 mm eyepiece: G2=20,M2=120,f=6mm.

And finally, we come to another important feature telescope, this is the angular resolution. Determined from the formula: Q=140/D. Measured in arc seconds.

For LevenhukStrike 60NG this value is 1.8"" . If we want to observe beautiful binary stars, then we will first of all compare the angular distance between them, indicated in the reference book, with our value Q, to see if this is possible.

Example 3 - double star, alpha Canis Hounds

For example, #10 in the handbook is a double star, alpha Canis Hounds, consisting of two components: 2.9m and 5.6m, spaced 20"" apart. It is clear that Q<20 about once every seven. Such a star couple will be resolved with a margin. Don't forget to also compare the magnitudes of the components in the binary pairs with the penetrating magnitude admissible for observation for LevenhukStrike 80NG. She is equal 11.6 m, anything less is visible.

Observations of double pairs require the use of resolution magnification. It is different for every telescope. In general, a sufficient resolving increase is considered to be the value Mrazr=1.4D, which for our telescope is 112x. Increases more 112x details will not be added, but the aberrations in the classic achromat will grow noticeably. Therefore, the option with an excess increase M4 not needed.

Even when observing the Moon, it is better to buy a lunar filter than to reduce the brightness by increasing the increase. It is also useful to have a solar filter. You can't watch the Sun without it!

ATTENTION:
Do not look through a telescope at the Sun! This can lead to permanent damage to your eyesight.

The bottomless starry sky has always beckoned us. Away from city lights, countless scatterings of stars in themselves already make an indelible impression, but, alas, the possibilities of human eyes are very limited. Therefore, every amateur astronomer quickly comes to the conclusion that in order to see more, a telescope is simply necessary. Let it be small, but it will already be possible to see the details of the lunar surface, the satellites of Jupiter and even the rings of Saturn, open star clusters and some deep space objects.

How to choose your first telescope?

But the process of choosing the first telescope is often not easy for a novice observer: the eyes literally run wide from the huge assortment in specialized stores. And although there are no universal telescopes, based on the many years of experience of domestic and foreign astronomy enthusiasts, in most cases the ideal first telescope is a small refractor on a simple azimuthal mount. Such devices are easy to use, reliable and do not require any maintenance; they can be used with equal success both for astronomical observations and for viewing ground objects. It is these telescopes that are included in the series Levenhuk Strike NG. It includes three Levenhuk Strike 50 NG, Levenhuk Strike 60 NG and Levenhuk Strike 80 NG models with 50, 60 and 80 mm lenses respectively.

Levenhuk Strike NG Series of Telescopes for Beginner Astronomers

This series was developed and produced by Levenhuk specifically for beginner astronomy enthusiasts who are making their first observations and are just learning how to work with a telescope. The scope of delivery of the series telescopes includes everything you need for observations: inside the colorful box, in addition to the telescope itself, you will find two eyepieces, a Barlow lens, a compass, a movable star chart, a CD with a planetarium computer program, and a book for beginner observers "See All !

Design features of telescopes

All telescopes of the series Levenhuk Strike NG are of high quality workmanship and with careful handling will serve you for many years. Their lenses are made of high quality optical glass and coated with a multi-layer antireflection coating. Thanks to its lightness and compactness (the older Levenhuk Strike 80 NG model weighs less than 5 kilograms, the younger models are even lighter), the telescope is easy to transport and can be used as a lightweight hiking tool. The telescope is worth taking with you, even if you go to nature during the day: when using a diagonal mirror, it gives a direct mirror image and can be used to observe distant ground objects.

telescopes Levenhuk Strike NG are equipped with red dot finders that allow you to quickly aim at objects visible to the naked eye (Moon, planets, bright stars). Telescope tubes are painted white - a kind of classic coloring of astronomical instruments, thanks to which they are clearly visible at dusk and even in the darkness of night, and during the day they do not heat up so much in the sun. The telescope tube attaches to the mount in just a few seconds, so it doesn't take much time to prepare for observations. The tripods of the mounts are equipped with convenient tables for accessories, on which you can place a star chart or an unused eyepiece during observations.

Levenhuk Strike 50 NG and 60 NG Telescopes

Let us consider how different models of telescopes of this series differ from each other. and - younger models with 50 mm and 60 mm lenses, the lightest and most compact, but at the same time they have very modest capabilities. The fact is that the main characteristic of the telescope is not the magnification, but the diameter of the lens - the larger it is, the more you can see through this telescope. Another drawback is the focuser for 0.96-inch eyepieces, which limits the choice of additional eyepieces and does not allow the telescope to be used as a photographic lens. These models should be chosen by those for whom the dimensions and light weight of the telescope play a decisive role - such a device will not be a burden and will not take up much space in your luggage.

For a visual illustration of the capabilities of the telescopes of the series, let's see how you can see the same double star in each of them. In the figure in a white square, from left to right: senior, middle, junior.

Levenhuk Strike 80 NG Telescope

The top model in the series with an 80mm lens that delivers high image quality. In addition, this telescope has a 1.25-inch focuser, thanks to which it can be easily equipped with almost any eyepieces - their range is simply huge. In addition, you can attach a digital camera to shoot in direct focus. Of course, you should not count on getting beautiful photographs of nebulae with this telescope, but it is quite possible to get good photographs of the Moon or terrestrial objects.

Therefore, if possible, you should opt for the older model: although it is a little heavier, its capabilities compensate for this shortcoming. The main characteristics of the telescopes are given in the summary table at the end of the article.

Moon and mobile communication tower via Levenhuk Strike 80 NG

Any of the telescopes in the series Levenhuk Strike NG It will be a great gift for both adults and children. This is a great choice for exploring the starry sky: reliable and easy to use, it will open up a new world of heavenly bodies, allow you to acquire the necessary skills and experience. And then, if you buy yourself a large telescope to see even more, you no longer have to learn how to work with it - you will know how and where to look and what you can see there.

A wonderful telescope, although not yet fully aware of its capabilities, with a barlow lens and a 6 mm eyepiece, Saturn is seen gorgeously with all the details, Jupiter, the Moon and other planets of the solar system are clearly visible, with the exception of Uranus and Neptune, galaxies and some nebulae are visible, in general the telescope is great! 5

Answer:

I recently bought this telescope. To be honest, I expected more from him. Large craters and seas are visible on the Moon, some galaxies, stars, but in general it is good only for the Moon and Jupiter. For a beginner, it is very useful (which I was), but then you get tired of it and you want a larger and more powerful telescope. 8 telescops out of 10 5

Answer:
Thank you for your review of Levenhuk Strike 80 NG!

Hello! I bought this telescope two years ago, when it first appeared. For a beginner, this is a great telescope. And it's good in the city (we have little exposure), and outside the city. How many times have been on the road, and as good as new. Nothing loosened, did not unwind) Thanks for the wonderful telescope) 5

Answer:
Thank you for your review of Levenhuk Strike 80 NG!

I really liked the telescope, sorry just black and white 5

Answer:
Thank you for your review of the Levenhuk Strike 80 NG. The image observed by the eye through the eyepiece is usually colored, but not always. The image will be colored when observing terrestrial objects, as well as the Moon and planets, you can see the colors of some stars. At the same time, faintly luminous objects in deep space, such as galaxies or nebulae, are visible through a telescope as grayish clouds. However, when observing in large telescopes with a lens diameter of 250-300 mm or more, barely noticeable colors can be seen in the brightest deep-sky objects. In addition to the aperture of the telescope, much depends on the conditions of observation (primarily on the level of illumination), the adaptation of the eyes to darkness, and the individual characteristics of the observer's vision. But even with the largest professional telescope it is impossible to visually (i.e., with the eye) see deep-sky objects as bright and colorful as we are used to seeing them in photographs.

Compared to some telescopes, this one is a piece of fluff. Levenhuc strike 80 ng weighs 6 kg, and some can reach 40 kg in weight 5

Answer:
Yes, indeed, thanks to the azimuth mount, the Levenhuk Strike 80 NG telescope weighs a little less than 5kg, which makes its transportation not burdensome and installation easy.

I’m reading your questions and I don’t understand .. is it really not possible to search for answers on the Internet or at least in the product description, or even in the same questions, only a few lines below!? Is it really that our people have become so stupid that it's easier to ask than to develop yourself .. sadly On the site, there is a wonderful section: http://www.site/articles/telescopes/ - there are answers to 99% of the questions you ask. 5

Answer:
Thanks for your feedback!

I bought it, so far I have not been able to try it with a Barlow lens. This miracle weighs with a complete set of 6.5 kg. The program that comes with the kit is great, you don’t even need a telescope with it))). As long as everyone is satisfied. 5
