Time-proven optics for your first astro-steps – the telescope
By choosing the Pollux-I, you’ll start your journey to the stars with a classic Newtonian reflector telescope. Beginners are often surprised by the fact that with telescopes of this type you don't look in at the back of the tube, but at the front and laterally. This gives you the advantage of always being able to look into the telescope in a comfortable posture, even when it's pointed vertically upwards at the sky. In addition, these reflector telescopes offer optics that are absolutely free of chromatic aberrations and thus provide good imaging properties.
The large aperture of 150 mm collects a lot of light from the celestial objects. In addition, 150 mm aperture and 750 mm focal length result in a short focal ratio (ratio of aperture to focal length) of 1 to 5 (F/5). On the one hand, this makes the telescope fast and provide a bright image. On the other hand, high magnifications can be achieved. This combination makes the entry-level telescope so versatile. In addition, the Pollux-I is equipped with a parabolic primary mirror. The remarkable effect of this special mirror shape: you enjoy excellent imaging properties at all magnification levels.
So you can look forward to the complete range of celestial highlights. At low to medium magnification, you can admire deep-sky objects such as open star clusters, globular clusters, gas nebulae and even galaxies such as the pair of galaxies M65 and M66 in the constellation Leo. And at high magnifications, observing the planets or details on the Moon is an absolute pleasure.
You can get really close to your favourite objects: The aperture of 150 mm achieves a resolving power that allows magnifications of up to about 300x with sharp images. Technically, even higher magnifications are possible, theoretically up to 562.5x using the included accessories. However, with increasing magnification, the sharpness of the image can slowly decrease. In addition, the prevailing conditions always make a difference: How highly you can magnify always depends not only on the power of the telescope but also on the air turbulence in the atmosphere (seeing conditions).
The telescope also impresses with its flexibility in terms of eyepiece compatibility: it comes with a 2-inch focuser (focuser extension) and an adapter from 2 inch to 1.25 inch. This enables you to use eyepieces with 1.25-inch sockets (about 31.7 mm) as well as eyepieces with the larger 2-inch sockets (about 50.8 mm) with large fields of view.
Note for nature lovers:
If you choose a Newtonian telescope like the Pollux-I reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed laterally reversed as well as upside down, which makes no difference when observing the sky. However, this type of telescope is less suitable for nature and landscape observation during the day. Would you like to use your new telescope for exciting nature discoveries as well? Then we recommend that you choose one of the BRESSER refractor telescopes.
Perfect foundation for fascinating discoveries – mount and tripod
Your beginner's telescope is securely held by the height-adjustable aluminium tripod with equatorial mount. The special feature of this mount, also known as a parallactic mount: in contrast to azimuthal models, the movement of the celestial bodies is only compensated for on one axis instead of two. For this purpose, you simply align one axis parallel to the Earth's axis by pointing it approximately at Polaris.
For precise and comfortable alignment and tracking of the entry-level telescope, the Pollux-I comes equipped with two flexible shafts with fine adjustment. And to ensure that the interchangeable eyepieces, barlow lens etc. always remain within reach, they can be stored 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!
Well equipped for the ideal start – the accessories
Your entry-level telescope comes with a wide range of astronomy accessories so that you can start to be amazed right away. For example, the LED viewfinder helps you align the telescope and find celestial objects. Installed in parallel on the telescope, this direction finder shows you a red dot when you look through it. It appears to hover in front of the sky and thereby shows you where the telescope is pointing.
Varying view of the sky: With the two eyepieces with 1.25-inch sockets (31.7 mm), you can admire your astronomical discoveries at different magnifications. The 3x barlow lens already included in the set triples the magnification of the eyepiece you are using.
Enjoy safe observations of our Sun with the included solar filter. This way you can easily take a closer look at sunspots and granulation on our own star.
CAUTION: Never point the telescope at the Sun without the solar filter!
Astrophotography for beginners: with the smartphone adapter, you can use your mobile phone as a camera on the telescope. This way you will quickly impress friends and relatives with your own first snapshots e. g. of the Moon or the Sun.

- 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. The battery should NOT be stored together with hazardous or flammable materials. Store the battery in a cool, dry, and well-ventilated area. The battery should NOT be inserted incorrectly when charging. MAKE SURE the battery compartment is empty, dry, and free of dirt before inserting the battery. The battery should NOT be charged in direct sunlight or at extreme temperatures. The battery must be charged at room temperature, typically between 20 °C and 26 °C (68 °F-79 °F). Charging may be temporarily suspended if the battery temperature exceeds 60 °C (140 °F). If the battery is hot but the temperature is under 60 °C (140 °F), the battery will still charge, but more slowly than usual. Avoid dropping the battery or the product with the battery inside. If dropped onto a hard surface, the battery or product may be damaged. If you suspect the battery might be damaged, replace it. Never leave your mobile hotspot plugged into the power supply for more than 24 hours to charge. Let the battery drain and then recharge it. Keeping your mobile hotspot plugged into a charger without draining the battery can damage the battery/device or affect performance. If a battery shows a significantly shorter runtime than when purchased, it has reached the end of its reasonable lifespan. We recommend replacing it. For optimal results and performance, batteries should be replaced after 12 months or earlier depending on usage. Follow local regulations for the disposal of used batteries. Do not throw the battery into fire or water.
