The TS Optics JUPITER is a versatile beginner´s telescope with very sharp optics.

The classical refractor according to Fraunhofer with its fully coated objective provides a clear and contrasty image. It makes your first astronomical observations a success. The telescope is quickly set up and handling is very easy. Of course, an easy to understand manual is supplied. The telescope is suitable for all stargazers of age 7+ and offers joy in astronomy right from the beginning.

The optics of the TS Jupiter beginner´s refractor
This telescope already gathers approximately 100x as much light as the human eye. Thus you are able to see hundreds of nebulae, star clusters and galaxies beyond our solar system. The high resolution shows exciting details of objects in our solar system, like the crater landscape of the moon or the rings of saturn. Get enchanted by the changing positions of Jupiter´s moons, like Galileo Galilei once before.

The equatorial mount EQ3-1 of the Jupiter:
Good optics need a stable mount. We don´t offer this refractor with a small EQ1 mount, we sell it on the stable EQ3-1 mount instead. The image stands still even at high magnification. The mount is very easy to set up and can easily be handled by any beginner.

The mount offers professional functions such as:
polar fine alignment for precise setup
oversized field tripod
well suitable counterweight for optimal balance
manual slow motion control in both axes through flexible shafts
tracking motor available optionally

(see "recommended accessories")

Extensive and high-quality accessories included even in the standard equipment:


The finder scope: the finder helps to find the objects in the sky or on earth. The integrated crosshairs help centering the object.

Further accessories:
A beginner wants to start watching immediately, not to start buying more equipment, so practical accessories are included:
star diagonal for comfortable viewing
a quality 25 mm Plössl eyepiece for overview
a quality 6.5 mm Plössl eyepiece for maximal magnification
moon filter for decreasing glare
errecting eyepiece for terrestrial observation with correct orientation
3x Barlow lens for more focal length offers stronger magnification if used with the 25 mm eyepiece

Observing with the TS JUPITER

The moon
Craters and ridges can be seen easily. Watch the sun rise in the craters while more and more detail becomes visible!

The Planets
Observe the phases of Venus or the rings of Saturn. On Jupiter you can see many details including the atmospheric bands and the Galilean moons. Under good conditions you can see the great red spot - a huge hurricane twice the size of our home planet!

Stars, galaxies and nebulae
Hundreds of celestial objects are within reach of this telescope. Compared with the naked eye, the telescope collects almost 140x as much light! Hundreds of nebulae, star clusters and galaxies are within reach of the JUPITER telescope.

Point, for example, the instrument to a remarkable cloud in the milky way close to the constallation Aquila. Look through the telescope at low magnification, and suddenly the diffuse cloud turns into a sea of stars, with a nebulous spot in the middle of the field. Now use a higher magnification and the watch the spot turning into a pretty star cluster within the ocean of stars of the milky way.

The Sun
With the optionally offered filter film Baader AstroSolar, high-contrast solar observations are possible.

Warning: never point a telescope (or even a finder scope) to the sun without correct front filter or accessories of similar safety, as you risk immediate blindness! The safety of your eyes should be worth the 25 Euros for one sheet of AstroSolar. The filters screwed into eyepieces are not safe, as they tend to burst without warning.

Our Earth
You can also use this telescope as a powerful spotting scope for viewing planetside objects such as birds, ships and mountains. The telescope offers a very good image sharpness for planetary observing, the errecting eyepiece gives the right orientation.

Instruction manual

What can I observe with the beginner´s telescope JUPITER:
A refractor with 70 mm aperture is already a powerful telescope. It has already approximately 12x the aperture of the naked human eye. And a lens with 70 mm diameter already collects 36% more light than a lens with 60 mm aperture.

That means:
With this refractor, objects are already visible which
cannot be seen with the naked eye, and objects with structures, like planets, already show details which cannot be resolved even in binoculars.

Magnification:
The highest useful magnification of a refractor (telescope with lenses) with 70 mm aperture is approximately 180x. This magnification shows all details which can be resolved by an objective with this aperture. The upper range of magnification is used for moon and planets, as deep-sky objects are too dim.

The lowest useful magnification is about 20x. With a good eyepiece, a refractor like this shows approximately 2.5°, which is approximately 5 times the diameter of the full moon. Large diffuse nebulae or extended star clouds become visible.

The following examples can describe the attraction and fascination of live observing through a telescope only incomplete. They shall give you a first impression of the performance of this compact, but powerful telescope.


A refractor with 70 mm aperture is also a fine spotting scope for terrestrial observations. Especieally well suited for this purpose are refractors on an alt-azimuth fork mount.

Examples for observations:
Birds or other animals in trees. You can focus from approx. 5 m distance, so you observe even shy animals without scaring them up.

More distant objects:
Whether you watch sailing ships at the horizon or mountaineers on the steep face, the refractor with its 70 mm aperture will show you many details.


The image at left was taken with a digital camera through a refractor like it is offered here.




At the border between terrestrial and astronomical viewing, you find risings and settings of astronomical objects - particularly striking in twilight when the contours of the foreground objects, in this case a tree, stand out against the slightly lightened sky.

These beautiful impressions also cannot only be observed with this small refractor, but also be photographed, too.


The exposure times are so short that the apparent motion of moon or sun has not yet had an impact as blur.




The moon is already a very rewarding object even in a small telescope. The crater landscape and the maria can be seen already on the photograph. The maria are the large dark regions. Especially important for photography with the refractor is the focuser. It has to be rather stable and, above all, accept 1.25" eyepieces or accessories. At a magnification of approx. 100x, the moon completely fills the field of the eyepiece. The craters are even more clearly visible than on the image. You can see the Montes Apenninus or the Montes Alpes (welll-known mountain ranges on the moon) very well.

Especially fascinating is the region between light and shadow, the terminator. Here, craters and mountains stand out in a particularly sculptured way, as the elevated parts cast prominent shadows. On the image, crater can also be seen particularly well at the border between light and shadow. By the way, the best time for observing the moon is at half-moon. On the contrary, full moon is not particularly interesting, as there are almost no structures to be seen.




Caution! Please never observe the sun through a telescope without some protective device - serious damage to your eyes can result!

Despite this, the sun is a very rewarding object. We offer complete solar filters which are placed in front of the objective. The image at left gives an impression how the sun looks if watched through a refractor with 70 mm aperture with filter. The dark formations are already the sunspots, "cooler" areals on the hot surface of the sun.


If the air is especially calm, you will already notice a light grey region around the pitch-black sunspots - the penumbra. Observe rising and falling of the sunspot number according to the solar cycle. You can also watch the transit of Venus or Mercury across the sun.




With a food refractor, you can already observe some interesting details on the surface of the planets of our solar system.

Mercury
The planet closest to the Sun will rarely be more than a small bright spot. Only if the air is very calm and the planet at the right position, one can recognize a tiny little crescent.


Venus
Depending of the position from Venus to sun and earth, it looks like a little moon. The large crescent can already be seen well even at medium magnification.


Mars
Mars is a small spot. First details can be seen at mars oppositions. Magnification should be as high as possible.





Jupiter
A very beautiful object for observing. The image above shows how Jupiter looks like in the small refractor. Very nice to see are the prominent cloud bands, but you can also watch the movements of the four big moons of Jupiter. Jupiter is like a miniature solar system. Magnification should be as high a possible.

Saturn
The well-known ring and also the bright moon Ttan are already visible in the small refractor. The ring planet offers a fascinating sight in the telescope. Magnification should be as high a possible.

The remaining planets can be recognized, but for details, you need significantly larger telescopes.




Beyond the solar system, there are also many interesting objects waiting for you. 70 mm aperture already have a good light-gathering power.

At this point at the latest, the good 1.25" focuser pays off, it allows using eyepieces with 1.25" barrel size which can cover a large area of the sky. Many interesting objects are very extended, but relatively faint, therefore a low magnification should be chosen.


The image at left shows like the open cluster M11 looks like when seen through the rafractor with 70 mm aperture. Many open cluster can be resolved into single stars. Take a look at the well-known double cluster h+chi Persei, and you can see hundreds of single stars in the field of view of the eyepiece.



Bright nebulae and galaxies are also within reach of the refractor. The Orion Nebula or the Andromeda Galaxy are diffuse patches, but if one knows which distances are overviewed at that moment, one is quickly astonished. The ligth of M31 needs more than to million years until it is focused by the objective of this refractor.


Especially beautiful objects are double stars like Mizar and Alcor in the Big Dipper. Many double stars can be distinguished with this 70 mm refractor.


In total there are many hundreds of interesting objects waiting for you. The light impressions are very delicate - barely visible. But with a little imagination, one can already make a guess of the depth and the diversity of the universe with the refractor with 70 mm aperture.
