Classic telescope for a new generation of stargazers – the telescope
Children and beginners in particular benefit from the classic design of this lens telescope, which is also called an achromatic refractor according to Fraunhofer. This is mainly due to its easy handling – ideal for your fist steps in celestial observation. The entry-level telescope owes its good imaging properties to the optics’ modern, precise coating.
The 102 mm aperture already collects a lot of light from the celestial objects. But it is due to the very short focal ratio (ratio of 102 mm aperture and 460 mm focal length) of about 1 to 4.5 (F/4.5) that you can enjoy an extra-bright image. Another advantage of the combination of short focal length and fast focal ratio: the beginner's telescope shows you the details in the Milky Way and extended gas nebulae such as the North America Nebula NGC 7000 particularly impressively. This makes a ''trip'' through the Milky Way with low magnification so much fun. However, the telescope will also give you a lot of pleasure while travelling on Earth, because it is very compact and thus perfect as a travel telescope.
And what about the magnification? Here, too, the aperture of 102 mm shows its effect: It gives the telescope a resolving power that easily allows magnifications of up to about 200x with sharp images. From a purely technical point of view, this is by no means the limit – with the included accessories, you can theoretically magnify up to 345x. The image sharpness can slowly decrease with increasing magnification, though. However, the degree of magnification achievable does not only depend on your telescope. The air turbulence in the atmosphere (seeing conditions) also influences your astronomical observations.
Set up, align, start marvelling – mount and tripod
Found the perfect location for your observations? Then attach the telescope tube to the eight-adjustable aluminium tripod with equatorial mount and off you go. The special advantage of equatorial mounts: Unlike with an azimuthal mount, you don't need to move both axes at the same time. Instead, you align one axis parallel to the Earth's axis by pointing it approximately at the polar star. Then you simply track the movement of the celestial bodies just on this one axis.
Because you move the axes via two flexible shafts with fine adjustment, you can adjust and track the beginner's telescope very precisely and comfortably. And for quick access to all your accessories, simply place them on the tray between the tripod legs.
Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable!
Must-haves for star observation – the accessories
In order for you to start stargazing right away, the astronomy set comes with many accessories. With the LED viewfinder, you can easily keep track of the sky. Just install the viewfinder parallel to the actual telescope and it projects a red dot onto a small ground-glass screen. When you look through it, this dot appears to be floating in front of the sky. Not just anywhere, but exactly at the point at which your telescope aperture is currently pointing. This allows you to align your telescope more precisely and find the celestial objects you have chosen for your night-time exploration much more easily.
As with everything else, a change of perspective is always fun. Therefore, the two eyepieces (4 mm and 20 mm) allow you to view the objects in different magnifications – and thus enjoy completely different views. You want to see even more details? Then triple the magnification of the eyepieces with the 3x Barlow lens. The telescope for beginners is also flexible when it comes to upgrades: the diameter of the sockets is 31.7 mm (1.25 inches), which is an international standard that applies to all manufacturers. So you can choose from a large variety of additionally available eyepieces.
In order for you to explore the universe with ease, the 90-degree star diagonal mirror always offers a comfortable view into the beginner’s telescope. Even if the telescope is pointed vertically upwards into the sky, you simply look in from the side – and just enjoy the view.
But it is not only at night that the sky attracts our attention with spectacular highlights. In the daytime sky, our nearest star is particularly worth seeing. You can observe it completely safely using the solar filter. You will be amazed once you take a closer look at the sunspots and the granulation on the Sun.
CAUTION: Never point the telescope at the Sun without the solar filter!
Capture your favourite moments of sky observation. You can easily take your first steps in astrophotography by using the smartphone camera adapter – for impressive snapshots of the Sun and Moon, for example.

- Check the solar filter before every solar observation and ensure that it is not damaged. Hold it against a strong light source to detect any possible cracks and/or holes. Do not use the telescope for solar observation, even if the solar filter is only slightly damaged. In this case, contact the manufacturer for the appropriate replacement parts.
- Always use the included solar filter when observing the sun. Make sure it is correctly attached to the telescope according to the instructions. The use of the solar filter is only intended in connection with this telescope.
- Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
- Check the secure fit of the solar filter before each solar observation. An accidental detachment from the objective opening can lead to immediate and permanent eye damage and blindness.
- If the solar filter cannot be securely attached to the tube, improve the fit by placing several self-adhesive felt strips or similar between the solar filter and the objective opening. Never use the solar filter if it cannot be properly mounted on the telescope. In such a case, always contact our customer service first.
- Be extremely cautious when observing the sun. A brief look through the unprotected optics will immediately cause severe eye damage, potentially leading to complete blindness.
- Children should not look at the sun through the telescope, even with the filter properly installed. Never leave children unsupervised.
- Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
- Do not observe the sun after eye surgeries or other eye conditions without prior medical consultation.
- Wrinkles/creases in the film are normal and do not indicate a product defect.
- Do not expose the device to high temperatures.
- BATTERY WARNING AND SAFETY Safe handling and use of batteries and accumulators Read and follow these instructions before using the battery or accumulator. To the extent permitted by law, failure to comply with these warnings and instructions may result in any damage caused to your product not being covered by the warranty. In this document, the term "batteries" also includes accumulators. Follow these instructions to ensure optimal safety and performance: DO NOT use counterfeit batteries in products. Only use supplied batteries. Use the battery SOLELY for its intended purpose. Keep batteries out of the reach of children and pets. DO NOT use batteries that appear to be damaged, swollen, or modified. Do not use batteries that are leaking, emitting a smell, swollen, melted, or showing dents, rust, cracks, or scratches. The battery should NOT be disassembled, crushed, punctured, shredded, or otherwise tampered with. The battery should NOT be exposed to liquids. Liquid may penetrate the battery's circuits, causing corrosion and compromising its safety. A wet or damp battery should NOT be dried with a device or heat source (e.g., hairdryer or microwave). The device or battery should NOT be placed near a heat source or direct sunlight. High temperatures can cause the battery to swell, leak, or malfunction. Examples include placing the device near a radiator, stove, kitchen appliance, iron, fireplace, or inside a vehicle or next to a window in direct sunlight. The battery should NOT come into contact with metal objects. If metal objects such as jewelry come into prolonged contact with the battery terminals, the battery may become very hot or catch fire.
