Product information "BRESSER Messier AR-90L/1200 Optical Tube assembly"
NEW - now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation.

Excellent for entering into the hobby of astronomy: 90mm aperture delivers 200 times more light than the naked eye! Observe craters, valleys and rims on the moon from nearly 400,000km away just as you would look out of the window of a spaceship! 
The MESSIER AR-90L does not only provide highly detailed views of the moon: Gaze at the division of the rings of saturn millions of kilometers away or explore the Great Red Spot of Jupiter, a giant tornado in Jupiter's atmosphere. Watch the seasons on Mars and find the sickle of Venus. 
The MESSIER AR-90L gives you images that are many times brighter than the instrument Galileo Galilei was using for his famous explorations almost 400 years ago. 

This telescope is an optical tube without mount and tripod.

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.

BRESSER Barlow Lens 2x 31.8mm/1.25"
With the usage of barlow lenses, you can extend the equivalent focal length of telescopes and hence increase the magnification of your observed targets. Subsequently, you can use lower power eyepieces in Barlows to act as much more powerful eyepieces, but retain the larger ocular size and more comfortable viewing that comes with lower power eyepiece designs.Due to their two lens design, these Barlow lenses provide a brilliant image quality for the whole visual field and are suitable for observations and photography.  The black coloured Barlow element cell in this BRESSER Barlow Lens 2x 31.8mm/1.25," can be unscrewed and has the same thread as 1.25" filters, allowing it to be mounted in 1.25" eyepieces, t-adapters and other accessories, giving you flexibility of use and the ability to vary magnification in different accessories.  For instance, the black Barlow cell screwed into the average length nosepiece of a standard push fit t-adapter will give around 1.6x magnification on an attached DSLR.  This can be very useful when trying to get to photographic focus with some Newtonians and Solar Telescopes, which lack the necessary amount of in focus travel to get a camera to a prime focus position.FEATURESsuitable for observations and photographydoubling of the focal lengthtwo lens designfully multi-coatedWHAT'S INCLUDEDBarlow lens (1pc)

The rings of Saturn will be accentuated, the structures of the Venus Atmosphere will be even finer. EXPLORE SCIENTIFIC 1.25" Filter Grey ND0.9 - 0310245 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. What ist a color Filter for and do we really need it? Color Filters darken the light slightly, that reaches the eye or the sensor of the camera. This eliminates for instance stronger transitions. The result is that your picture turns out with more contrast which automatically shows more details.

BRESSER Lyra 70/900 EQ3 Refractor Telescope with Smartphone Adapter & Solar Filter
Unpack, set up, enjoy – with this complete telescope set you will soon begin your first exploration of the night sky. All the equipment for your new, exciting hobby is already included: the lens telescope with 70 mm aperture and 900 mm focal length, the equatorial mount, the tripod and a wide range of accessories for astronomical observations. Ideal for beginners: the system is very easy to handle and can even be used by children. Well-proven design for an easy beginning – the telescope With this set you'll start your voyage of discovery to the stars with a classic refracting telescope, a so-called achromatic refractor of the Fraunhofer type. The advantage of this particular design: even beginners as well as children can use it with ease. In addition, the Lyra refracting telescope impresses with good imaging properties due to its modern, precisely coated optics. If you compare this entry-level telescope to a corresponding astronomical telescope with a 60 mm aperture, you will notice: With its 70 mm aperture, the Lyra already collects 36 % more light. It also offers better resolution. In addition, 70 mm aperture and 900 mm focal length result in a very large focal ratio (ratio of aperture to focal length) of about 1 to 12.9 (F/12.9). The impressive result: a very sharp image with good contrast. Enjoy the view of our natural satellite, the Moon. Or take a look at the planets. Even the famous Pleiades sparkle captivatingly in your field of view. For the long focal length makes the telescope a specialist for observing the Moon, Sun, planets and open as well as globular clusters. And how big will these eye-catchers of the sky appear? Thanks to the 70 mm aperture, the resolution allows magnifications of up to 140x with really sharp images. Technically, much more would be possible – theoretically up to 675x using the included accessories. However, then the image sharpness could slowly decrease with increasing magnification. Of course – as with everything in astronomy – the prevailing conditions also play a role: So, how much you can actually magnify is determined not only by your telescope's performance but also by the air turbulence in the atmosphere (seeing conditions). Perfect foundation for your glimpse into space – mount and tripod Once you have found the ideal location for your astronomical telescope, you can quickly start exploring the sky. Simply mount the tube with the equatorial mount on the height-adjustable aluminium tripod. This special type of mount has the advantage of particularly convenient tracking: for this purpose, an axis is aligned parallel to the Earth's axis by pointing it approximately at Polaris during the so-called "alignment". Afterwards, the movement of the celestial bodies can be conveniently compensated for on this one axis rather than on both at the same time, as is the case with an azimuthal mount. In addition, the two flexible shafts with fine adjustment ensure the very precise and comfortable adjustment and tracking of the entry-level telescope. Always the right accessories at hand: the storage plate between the tripod legs provides space for eyepieces, barlow lens, solar filter etc.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! All-round equipment for astronomy newbies – the accessories Moon, planets or the Sun – with the extensive accessories you will get the best out of your astronomical telescope for any observation object. But initially, the LED viewfinder helps you find the nocturnal celestial bodies in the first place. To do this, the direction finder is installed and aligned parallel to the actual telescope. When you then look through it, a small red dot appears to hover in front of the sky. It shows you the spot at which the telescope is pointed. In this way, you precisely align the tube and easily find your objects before you gaze at them through the higher magnification of the telescope. Change of perspective for stargazers: using the two eyepieces you achieve different magnifications. They can be switched easily: With their standard socket diameter of 1.25 inches (31.7 mm), they are simply inserted into the eyepiece focuser of the entry-level telescope. Looking for even more detail? Then grab the 3x barlow lens and triple the magnification of the eyepieces. Comfortable observation at all times: a 90-degree star diagonal mirror is included. So, even if the telescope points vertically upwards into the sky, you can still look in comfortably from the side. For exciting discoveries during the day simply attach the safe solar filter to the telescope’s aperture. This way you can take a closer look at our own star and marvel at sunspots and granulation on the sun. CAUTION: Never point the telescope at the sun without the solar filter! Take the plunge into the fascinating world of astrophotography with the smartphone adapter. It allows you to use your smartphone as a camera on the telescope – and easily take exciting snapshots of your favourite celestial bodies such as the Moon or the Sun. FEATURES Beginner’s lens telescope with 70 mm aperture and 900 mm focal length Achromatic refractor type Fraunhofer Well suited for observing the Sun, Moon, planets and star clusters Height-adjustable tripod with equatorial EQ3 mount Sensitive adjustment through flexible shafts and fine adjustment in both axes Easy to use, very suitable for beginners and children Focal ratio F/12.9, thus very sharp image and high contrast 1.25 inch (31.7 mm) eyepiece focuser Two eyepieces and one barlow lens with 1.25 inch (31.7 mm) extension tubes for different magnifications Safe solar observation with the included solar filter First steps in astrophotography with smartphone camera adapter SCOPE OF DELIVERY Telescope Aluminium tripod Equatorial EQ3 mount Eyepieces: 4 mm and 20 mm (1.25 inch sockets) Barlow lens, 3x (1.25 inch socket) Star diagonal mirror LED illuminated dot finder Solar filter Smartphone camera adapter Accessory tray Astronomy software download Instruction manual
