That is normal. Finder scopes are only used to make objects easy to locate. The image orientation does not matter for observation.

  • Alt-azimuth: easy to use, moves horizontally and vertically
  • Equatorial: enables precise tracking of objects with only one axis – ideal for high magnifications and astrophotography

  • Moon: from 30 mm
  • Planets: from 100 mm
  • Deep sky: from 150 mm

Warning notes
  • 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.

EXPLORE SCIENTIFIC 1.25" CLS Nebula Filter
Besides air turbulence, the brightening of the night sky is the biggest obstacle to observing faint objects beyond the solar system. Street lamps and other artificial lighting mean that the sky in human settlements is no longer really black. This affects the contrast and thus the perception of deep-sky objects. Depending on the type of celestial object, however, part of disturbing artificial light can be filtered out, making it easier to observe fainter targets.The EXPLORE SCIENTIFIC CITY LIGHT SUPRESSION - or CLS - filter uses the fact that the artificial lighting is not evenly distributed over the entire spectrum. These colours - in the case of the EXPLORE SCIENTIFIC CLS nebula filter, above all the typical colours of mercury and high-pressure lamps, used in street lighting - are suppressed, but the emissions of deep-sky objects are allowed through. With a slightly brightened sky, some relatively bright deep-sky objects are practically invisible with a telescope, for example the large galaxy M101. Using this filter makes observation much easier. A must have for any visual amateur astronomer.  The EXPLORE SCIENTIFIC CLS can also be used as a useful photographic filter - helping to improve the quality of your telescopic deep sky photos.The EXPLORE SCIENTIFIC nebula filters are delivered with an individual test report - so you can be sure of receiving high-quality filters.SPECIFICATIONS:eliminates disturbing light - e.g. from street lightingenables observation of faint deep sky objectsWHAT'S INCLUDED:1x CLS filter

EXPLORE SCIENTIFIC 1.25" H-Beta Nebula Filter
One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects bejond the solar systems enourmously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artifical light. The Explore Scientific H-beta filter uses a characteristic property of the so called emmission nebulae. Those objekcts glow in special colors, the so called emmission lines. Those emmission lines are linked to chemical elements - in this case hydrogen. The Explore Scientific H-beta nebula filter blocks all other colors (and thereby nearly all of the artificial light) and only the emmission line of the hydrogen can pass the filter. The result is astonoishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburbian skies for example the horsehead nebula is almost not visible with a 300mm telescope. By using this filter you can see the nebula and its structures without problems. A must for every visual observer. The Explore Scientific nebula filters come with a individual test certificate - your guarantee to receive a premium filter.

The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar system enormously. Depending on the type of the celestial object, it is possible to dramatically increase the contrast by blocking annoying artificial light. The EXPLORE SCIENTIFIC UHC filter "zeros in" on the wavelengths of so-called emission nebulae. Those objects glow in special colours - their emission lines. Those emission lines are linked to chemical elements - in this case hydrogen at 486nm and 656nm, plus oxygen at 496nm and 501nm. The EXPLORE SCIENTIFIC UHC nebula filter blocks all other colour wavelengths (and thereby nearly all of artificial light) and only the emission line of the hydrogen and oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely invisible from, without filters. In suburban skies, for example the Owl-nebula M97, the Veil-nebula NGC 6992 or even the bright Dumbell-nebula M27 are not clearly visible. Using this filter allows you to see nebulae and their structures in much finer detail. A must for every visual observer. The Explore Scientific nebula filters come with a individual test certificate - your guarantee to receive a premium filter.

BRESSER USB Motor Focuser for HEX and R&P
The BRESSER USB Motor Focuser for HEX and R&P lets you achieve pinpoint focus on your telescope remotely and without any physical contact – whether you're enjoying a casual visual session or pushing the limits of astrophotography. The EAF works with hexagonal (HEX), rack-and-pinion (R&P) and most other standard focusers, connects in seconds via USB-C, and gives you the choice between manual control via the hand controller and fully automated focusing through your astro software of choice. Hands-off focusing via hand controller The included wired hand controller lets you dial in focus from a distance without laying a finger on the telescope. For astrophotography, this is a genuine game-changer: imaging sessions run uninterrupted and your focus stays locked in from first light to the end of the night. Visual observers will appreciate it just as much – precise focus adjustments on demand, no fumbling in the dark. Autofocus and broad software compatibility The EAF integrates smoothly with the most popular astro software packages. The ASCOM driver covers the vast majority of Windows-based applications, while full INDI and INDIGO support makes it equally at home on Mac and Linux. If your software includes an autofocus routine, the motor will handle everything automatically – a real asset for long, unattended imaging runs.Temperature sensor for sharp results all night long As the night progresses, temperature drops can cause the telescope tube and optics to contract slightly – enough to nudge your focus point off target. The included temperature sensor tracks these changes continuously and, paired with compatible software, compensates for any thermally induced focus shift on the fly. The result: consistently sharp images from dusk till dawn, with no manual intervention required.Please note: The temperature sensor and hand controller cannot be used at the same time. FEATURES Precise electronic motor focuser Plug and Play via USB-C Compatible with HEX, R&P and most standard focusers ASCOM, INDI and INDIGO driver support for maximum software compatibility Autofocus support via third-party software Manual focusing via hand controller Temperature sensor to compensate for thermally induced focus shift Robust aluminium housing SCOPE OF DELIVERY Electric motor focuser Mounting plates Wired hand controller Screws Washers Flexible couplings USB cable Temperature sensor Allen key Manual
