FAQ - Frequently Asked Questions

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
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
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.

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 beyond the solar systems enormously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artificial light. The EXPLORE SCIENTIFIC UHC filter uses a characteristic property of the so called emission nebulae.

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 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 nebula filter

EXPLORE SCIENTIFIC 2" Grey- Moonfillter ND-09
The neutral density filter transmits light uniformly across the entire visual spectrum. It serves as an excellent filter to reduce glare and irradiation when observing the Moon with any telescope 4"(10.2cm) and larger. The ND96 filter may also be employed in the splitting of close double stars where one of the binary pair significantly exceeds the other in brightness.

EXPLORE SCIENTIFIC 2" H-Beta Nebula Filter
EXPLORE SCIENTIFIC 2" 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.

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 beyond the solar systems enormously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artificial light. The EXPLORE SCIENTIFIC O-III filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colours, the so called emission lines. Those emission lines are linked to chemical elements - in this case oxygen. The EXPLORE SCIENTIFIC O-III nebula filter blocks all other colours (and thereby nearly all of the artificial light) and only the two emission lines of the oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburban skies for example the veil nebula NGC 6992 is almost not visible with a 200mm telescope. By using this filter you can see the nebula and its structures without problems.

EXPLORE SCIENTIFIC 2" Variable Polarizing Filter
EXPLORE SCIENTIFIC 2" Variable Polarizing Filter
Universally usable variable polarizing filter with a  2" filter thread.This variable polarizing filter allows for a continuous adjustment of the image brightness. This is very helpful to level strong differences in contrast of different observation objects individually. Particularly for lunar and planetary observations but also for solar observations this filter prevents an outshining of details.Solar observations ONLY together with an adequate solar filter !!! Particularly when a Herschel wedge is used and with large objective lens apertures the use of the variable polarizing filter can reduce the brightness of the observation object to a confortable level. The large adjustment range of 40% to 1% light transmission and the neutral grey filter effect create a comfortable and unadulterated image.The handling is very simple. The desired filtering level is set by turning the two sides of the housing against each other.A 2.0" filter thread on both sides (female/male) allow for the simultaneous use of additional colour filters.FEATURESvariable polarizing filterindividually adjustable image brightnessmade from high-quality optical glassblack anodized aluminium housing2.0" filter thread on both sidesSCOPE OF DELIVERYpolarizing filterprotective box

EXPLORE SCIENTIFIC Dark-Sky Filter 77mm Slim
Universal Dark-Sky Filter with 77mm thread for photo lens. Contrast enhancing filter for Aurora- and Deep-Sky imaging. Especially during Aurora imaging the most important wavelength of 550nm (green) and 630nm (red) this filter let pass by 90%. In comparrision to CLS filters, the Explore Scientific Dark-Sky Filter is blocking also the yellow Sodium (Na) wave at 590nm which elliminates Sodium-lamp street illumination from your picture. This is very useful because the yellow light is always a partially mix of green and red light. Removing the yellow wave-length with any image processing software will always damping also the green and red coloring. For Aurory imaging this is of course not wanted. At these days of increasing light pollution, the Explore Scientific Dark-Sky Filter is absolutely recommended in order to take pictures also from urban conditions. Finally the slim housing design enables its use also with wide-field photo lens and doesn´t cause any vignetting.

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 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.

EXPLORE SCIENTIFIC TELRAD Projection Finder Scope with base
EXPLORE SCIENTIFIC TELRAD Projection Finder Scope with base
The TELRAD viewfinder is a projection finder that can be installed on any telescope and makes it child's play to align the telescope with the starry sky.The TELRAD viewfinder is a practical alternative to classic optical viewfinders and illuminated red dot viewfinders. You can see the complete starry sky without magnification, and not just a small section as with a normal optical viewfinder. Against this background of the starry sky, three red luminous concentric rings are projected, with apparent diameters of 4 degrees, 2° and 0.5° in the sky. Move the telescope so that the object you are looking for is in the inner ring, and the telescope points in the right direction. Because the object you are looking for is inside the ring, it will not be irradiated like a normal illuminated red dot finder.The base of the TELRAD viewfinder is self-adhesive and can be mounted on all telescopic tubes from about 10cm diameter. The length of the base is about 18cm. This base remains on the telescopic tube, the TELRAD viewfinder itself can be removed or attached at any time by means of the attached quick coupling. The TELRAD is powered by two normal AA batteries (not included).There are star atlases, like the "Deep Sky Travel Atlas" from Oculum-Verlag, and planetarium programs for the PC, like the program "Stellarium", where the three rings of the TELRAD are already drawn or can be displayed around the interesting celestial objects. This makes finding these celestial objects a real walk.FEATURESTELRAD projection finderIlluminated rings of 4 degrees, 2° and 0.5° in the skySee the complete starry sky without magnificationEasy installation and useCan be installed on nearly every telescopesBase with quick release coupling included Powered by two AA batteries (not included) Very long battery life because of LED technologySCOPE OF DELIVERYTELRAD viewfinder with projector and battery compartment TELRAD base with quick-release coupling for the viewfinder Adhesive tape for attachment to telescope

BRESSER Venus 76/700 AZ Reflector Telescope with Smartphone Adapter & Solar Filter
BRESSER Venus 76/700 AZ Reflector Telescope with Smartphone Adapter & Solar Filter
The BRESSER Venus 76/700 AZ reflecting telescope allows beginners to experience their very own stargazing hours quickly and easily. With the complete set, you are equipped with everything you need for your very own sky observations: an astronomical reflecting telescope with 76 mm aperture and 700 mm focal length, an azimuthal mount, a tripod as well as extensive accessories. And to guarantee a successful start in astronomy, the system is very easy to handle – the perfect first telescope for beginners! Established technology for your easy start – the telescope With this entry-level telescope, you will be able to admire the night sky through a classic Newtonian reflector. A little surprising for astronomy novices: with this particular type, you do not look in at the back of the telescope, but at the front and laterally. The advantage: even if the telescope aperture is directed vertically towards the sky, you can make your discoveries very comfortably. No need to bend down! In addition, the Newtonian reflector is very easy to use. The optics in this type of reflector telescopes are also impressive, because they are free of chromatic aberrations – resulting in good imaging properties at all times. A sharp image with good contrast – the Venus reflector telescope achieves this with its large focal ratio of about 1 to 9.2 (F/9.2 – calculated from 76 mm aperture and 700 mm focal length). Thanks to its long focal length, the telescope for beginners shows you the Moon, Sun, planets, open star clusters as well as globular clusters in a particularly impressive way. And all this at a magnification of up to 150x in really sharp images! Technically, you can magnify even higher – theoretically up to 525x while using the included accessories. However, as the magnification increases, the sharpness of the image may slowly decrease. Of course, how much you can magnify depends not only on the resolving power of your telescope. The air turbulence in the atmosphere (seeing conditions) also plays an important role. Note for nature lovers: If you choose a Newtonian telescope like the Venus 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. A good foundation for a successful start – mount and tripod The height-adjustable aluminium tripod and the azimuthal mount provide a firm footing and easy celestial navigation. Especially the azimuthal mount makes life easy for beginners, because it is very user-friendly: just like a typical photo tripod, you turn the telescope by hand to the left and right, up and down. This way, your favourite celestial objects quickly appear in your field of vision. Handy: to ensure that your astronomy accessories are always within reach, there is a storage plate between the tripod legs. Everything that goes with it – the accessories Out of the box straight to the fun of observing – with the complete astronomy set, you are quickly on your way to discovering the universe. The LED viewfinder helps you keep an eye on the sky. You just mount the direction finder parallel to the actual telescope and it projects a red dot onto a small ground-glass screen. This then appears to be hovering in front of the sky when you look through the viewfinder. And it does so at exactly the same spot that your telescope is pointed at. This way, the LED finder helps you to align the reflector telescope precisely and to find the celestial objects more easily. When it comes to the level of detail in your observations, the Venus beginner's reflector telescope gives you a choice: the two included eyepieces (4 mm and 20 mm) allow you two different magnifications. You want to get an even closer look? Then simply triple the magnification of the eyepieces with the 3x Barlow lens. In addition, the socket diameter of 31.7 mm (1.25 inch) complies with an international and manufacturer-independent standard. So you can easily expand your set – and with it your astronomical horizon. If you want to observe fascinating sights not only at night but also during the day, simply grab the solar filter. With it, you can safely admire spots and granulation on our nearest star – the Sun. CAUTION: Never point the telescope at the Sun without the solar filter! A new hobby leads to new impressions – and naturally you want to capture and share those. Therefore, you can easily use your mobile phone for your first steps into astrophotograpy with the smartphone adapter. Perfect for great snapshots of the Moon or the Sun, for example. Look forward to exciting astronomical discoveries by day and night – with the BRESSER Venus 76/700 AZ reflector telescope.
