BRESSER Universal Smartphone Adapter Deluxe

Observing the stars like a professional - very easy with the BRESSER JUNIOR refractor telescope 70/700 EL. It is a complete system for the exploration of the wonders of the universe, consisting of telescope, mount, tripod and all accessories needed. With an aperture of 70 mm it reveils already many details of celestial objects. The mount can not only swing the telescope left / right and up / down, it can also be used in a so-called equatorial mode, as scientists do in their observatories (see further under Special features). An additional finder scope mounted on the telescope is useful for locating celestial objects. With the erecting lens many exciting things in the environment can also be seen during daytime. With the height-adjustable tripod, the telescope can each be brought to an optimal height for large or small observers. The supplied diagonal mirror ensures a comfortable viewing. At night the moon and planets may like Saturn and Jupiter can be explored. But thanks to the 70 mm wide aperture of the telescope also many celestial objects outside our solar system are within the reach of this telescope. Star clusters many light years away and nebula impress young and old stargazers. SPECIAL FEATURESMounting with wedge: At first glance, the NG mount of the refractor telescope 90/700 NG is a very ordinary azimuth mount: an axis for left / right and one for up / down, as we know it from normal camera tripods. This mode makes sense especially with observations during the day. With the built-in wedge it can be tilted, so the whole mount can be converted to an equatorial mount for astronomy with a single operation. For use of the equatorial mount an axis is aligned with the North Star. When tracking a celestial object only a single axis needs to be moved, which clearly is a relief compared to tracking an object on the night sky with mounts that only have left / right and up / down axis.

Who doesn't dream of exploring the beauties of the universe with their own eyes? This complete telescope set allows you to make your first celestial observations immediately and very easily. It contains everything you need for your new hobby: a reflector telescope with 130 mm aperture and 650 mm focal length, an equatorial mount, a tripod and extensive accessories for astronomical observations. The system is easy to operate and very flexible. You can look forward to fascinating views of the Moon and planets. Star clusters and gas nebulae also look impressive through the user-friendly entry-level telescope. Easy start with the astronomy all-rounder – the telescope The set includes a true classic among the reflector telescopes, a so-called Newtonian reflector. With this type of telescope, you look in at the front of the tube instead of at the back. The advantage: the observing position always remains comfortable, even when the telescope is pointed vertically upwards. In addition to observing comfort, reflectors also impress with their optical performance. After all, they are absolutely free of chromatic aberrations and thus offer good imaging properties. Due to its 130 mm aperture, the entry-level telescope already collects a lot of light from the celestial objects. In addition, there is the short focal ratio (ratio of the aperture to the focal length) of 1 to 5 (F/5), which derives from the 130 mm aperture and the 650 mm focal length. As a result, the fast beginner's telescope shows a bright image and enables high magnifications. You also benefit from the flexibility of this astronomical telescope: Admire the fascinating view of open and globular clusters such as M13 in the constellation Hercules at low to medium magnification. Or marvel at gas nebulae such as the famous Orion Nebula M42. At high magnifications, on the other hand, the entry-level telescope brings you closer to the impressive planets and exciting details on our Moon. How big do the astronomical eye-catchers appear? Due to the resolving power achieved with the aperture of 130 mm, the telescope shows you sharp images at magnifications up to about 260x. With the included accessories, you can already reach 195x. The technology allows even more, but the image sharpness can decrease at even higher magnifications. However, it is not only the telescope that determines how much you can magnify. It also depends on the air turbulence in the atmosphere (seeing conditions). Note for nature lovers: If you choose a Newtonian telescope like the Pegasus 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. User-friendly base – mount and tripod Found the perfect place for your celestial observations? Then you can start installing your astronomical telescope on the height-adjustable stainless steel tripod with equatorial mount. The advantage over azimuthal mounts: you only have to move along one axis instead of two. The reason is that you align the other one parallel to the earth's axis beforehand. This so-called "alignment" is very easy: you simply point the axis approximately at Polaris. In addition, the mount comes equipped with two flexible shafts with fine adjustment. Perfect for aligning and tracking the telescope particularly precisely and comfortably. Everything always within reach: on the practical storage plate, your accessories are quickly at hand if needed.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! Complete astro package to start stargazing immediately – the accessories The comprehensive astronomy accessories make it easier for you to get started and enable you to see your favourite celestial bodies from completely different perspectives. To align the telescope and find your way around the night sky you can mount the LED finder parallel to the telescope. The method is simple: a red dot is projected onto a small ground-glass screen inside the viewfinder. When you look through the dot appears to hover in front of the sky – exactly at the point where the entry-level telescope is pointed. This way, you can easily find astronomical objects through the illuminated dot finder and then marvel at them in detail using the high magnification of your telescope. Vary your view of the stars: with the two eyepieces (10 mm and 25 mm), you can admire your nocturnal observation objects in two different magnifications. They are simply inserted into the eyepiece focuser of the telescope via their 1.25-inch-sockets, which is a standard diameter. You want to look even closer? Then the included 3x barlow lens can triple the magnification of the eyepieces. Explore the night sky on your own through the versatile BRESSER Pegasus 130/650 EQ3 reflector telescope. FEATURES Reflector telescope for beginners with 130 mm aperture and 650 mm focal length Reflector type: Newton Good for observing Moon, planets as well as star clusters and gas nebulae Height-adjustable tripod with equatorial EQ3 mount Precise positioning due to flexible shafts and fine adjustment in both axes Easy to use, very well suited for beginners Focal ratio F/5, thus well suited for many celestial objects 1.25 inch (31.7 mm) focuser Two eyepieces and a barlow lens with 1.25 inch (31.7 mm) sockets for different magnifications SCOPE OF DELIVERY Telescope Stainless steel tripod Equatorial EQ3 mount Eyepieces: 10 mm and 25 mm (1.25 inch sockets) Barlow lens 3x (1.25 inch socket) LED illuminated dot finder Accessory tray Astronomy software download Instruction manual

Open the case and you're ready to go: The BRESSER Arcturus 60/700 AZ lens telescope shows you the fascinating world of star clusters and planets. This complete set contains everything you need for your first steps into sky observation: an astronomical lens telescope with 60 mm aperture and 700 mm focal length, an azimuthal mount, a tripod and lots of accessories. The system is very easy to handle and therefore ideal for introducing children to astronomy as a hobby. And since there are so many beautiful things to discover on Earth as well, the telescope is suitable for observing nature and landscapes. Simply an astro-classic – the telescope With this classic lens telescope – a so-called Fraunhofer achromatic refractor – even beginners and children can easily gain new insights into the night sky. Thanks to the modern, precisely coated optics, the starter telescope offers good imaging properties. A sharp image with good contrast – this is ensured by the large focal ratio of about 1 to 11.7 (F/11.7), which results from the ratio of the 60 mm aperture to the 700 mm focal length. Perfect for exploring our Moon, the planets, but also open star clusters and globular clusters. And what about the magnification? The 60 mm aperture provides a resolving power that easily allows magnifications up to about 120x with really sharp images. Technically, even more is possible with this beginner’s telescope – up to 175x with the included accessories. However, as the magnification increases, the image can become more and more blurred. How much magnification is actually possible depends not only on the telescope, but also on the air turbulence in the atmosphere (seeing conditions). The foundation for moving impressions – mount and tripod For your nighttime observations, attach your telescope to the height-adjustable aluminium tripod with azimuthal mount. Thanks to its extremely easy operation, you can enjoy effortless astronomical explorations with this azimuthal mount. Just like with a normal photo tripod, you simply turn the starter telescope by hand up and down, to the left and right. To ensure that your eyepieces, compass, star map etc. are always within reach, simply place your accessories on the practical storage plate located between the tripod legs. Everything for a good start in astronomy – the accessories In the sturdy hard-top case, in which you can store the beginner's telescope perfectly and take it safely with you on your travels, you will also find lots of accessories. The 5x24 finder is a small miniature telescope that you simply mount parallel to the actual telescope. With its weak 5x magnification and integrated crosshair, it helps you keep track of the starry sky. So it allows you to easily find celestial objects and precisely align the telescope – before you then enjoy the view with the higher magnification. And how high the magnification is depends on which of the three included eyepieces (4 mm; 12.5 mm; 20 mm) you are currently using. To change the magnification, simply insert another one into the telescope's focuser. If at some point you want to change your field of view with additional eyepieces: no problem! The 1.25 inch (31.7 mm) socket diameter complies with an international and cross-manufacturer standard, so you can combine a wide range of optional eyepieces with your telescope. For a comfortable view at any time, you will also find a 90-degree diagonal mirror in the scope of delivery. Otherwise, you would have to lie down under the starter telescope in order to achieve good observation results when the optics are pointed upwards into the sky. Instead, you simply look in comfortably from the side. In addition to the night sky, the Earth also offers many captivating sights. That's why the 1.5x erecting lens turns the image the right side around, so that you can devote your entry-level telescope to observing nature and landscapes during day. However, because orientation in the night sky is not as easy as on our daytime planet, a compass and star map are included in the set. This way you always know where to look and what you will see there. Enjoy a quick start to the exciting hobby of astronomy with the BRESSER Arcturus 60/700 AZ lens telescope including all accessories. FEATURES Beginner’s telescope for astronomy 60 mm aperture and 700 mm focal length Achromatic refractor type Fraunhofer Ideal for observing Moon, planets and star clusters Height-adjustable tripod with azimuthal mount Easy to use, therefore suitable for children Focal ratio F=11.7, thus sharp image and high contrast Three eyepieces with 31.7 mm (1.25 inch) sockets for different magnifications With hard-top case for storage and transport SCOPE OF DELIVERY Starter lens Telescope Aluminium tripod Azimuthal mount Eyepieces: 4 mm, 12.5 mm, 20 mm (1.25 inch sockets) Star diagonal mirror Erecting lens 1.5x Finder telescope: 5x24 Accessory tray Hard-top case Compass Star map Instruction manual

Slides and cover glasses are an indispensable accessory which has also impact on the image quality. For most biological microscopes, the cover glass thickness is an important optical parameter, which is therefore included in the optical design and, if so, printed on the sleeve of every objective. You can usually see the number 0.17 which is the thickness in millimeters. For demanding applications in the laboratory, or for microphotography, using cover glasses with the desired thickness and high quality is necessary.The cover glasses included in the set are made of Boro 3.3 glass and are standardized to a thickness of 0.16-0.19mm. So they match the desired 0.17mm really good and give the best possible image quality. These Boro 3.3 cover glasses are pure white, without streaks and are pre-cleaned and ready to use. They are also especially suitable for fluorescence microscopy.The slides are made of soda lime glass, and have ground edges for safe handling. They have a matte field for writing on both sides (top and bottom). Slides and cover glasses are packed separately and in a vacuum sealed bag, containing moisture absorbent. They can be stored for a long time without loss of quality from hydrolysis and are easy to take out.

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. The BRESSER Messier 5" dobsonian is simply a breakthrough. Despite of its low price this telescope offers a versatility and quality rivaling a lot more expensive telescopes. Not only for beginners - also enthusiastic and experienced amateur astronomers love this high performance and compact telescope for traveling and to discover the night sky. The main goal of this telescope is the quick setup and the ease of use. Simply put the Messier 5" Dobson telescope on a table in your backyard, point the telescope to your target object and you are ready to start your observation. The Messier 5" Dobson is almost pre-assembled ex factory which means you can start within minutes. With the included standard accessories (LED-finder, 25mm and 9mm Kellner eyepieces and Moonfilter) the telescope is ready for observing. The inbuild compass and circular level speeds up the telescopes orientation. The optical diameter of 130mm (5") does not restrict your observations on solar system objects like the moon or the planets - you can reach farther into the sky and explore globular and open clusters, nebulae and galaxies. Finding and observing is much easier with that light gathering richfield telescope. Bresser also has equipped these dobsonians with a high quality main mirror which offers a very good sharpness and contrast. In addition, this telescope has a particularly large secondary mirror for ideal illumination of the image field.The optical tube can easily be moved inside the tube rings in order to find the optimal balance and observing position. This is another virtue of this highly versatile telescope system: Remove the optical tube from the dobsonian telescope mount and use the optics on a equatorial mount for astrophotography with smartphones und eyepiece cameras - in minutes. Bresser has not skimped and this telescope has a particularly large secondary mirror for ideal illumination of the field of view. The entire telescope tube can be moved and rotated in the tube clamps - everything is thus balanced in a flash and a comfortable position for viewing is set. A permanently installed compass with circular bubble facilitates the orientation of the telescope. This telescope is setting a new standard in usability, versatility and performance in its price class.Please note: Reflector telescopes with optical design “Newton” are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest BRESSER refractor (lens) telescopes for landscape and nature observing.

Color Filter Set Essential is recommended for Moon & Planets from 50mm (2") Aperture Essential Set includes the following filters: BRESSER Filter Red (1,25):The blue/blue green light is totally blocked. The contrast between the card and the lighter zones will enormously increase. This is truly helpful when you watch Jupiter or Saturn. Or for mars, watching the poles. BRESSER Filter Green (1,25):The green filter is to increase the contrasts enormously between the red and the blue regions of the cloud structures on the gas planets Jupiter and Saturn. Seeing our Earth Moon through the green filter, the contrasts of each ray crater become clearly more visible.BRESSER Filter Blue (1,25):The color of light blue really supports watching the high clouds on Mars. The contrast increases. The dark red structures will be shown even darker, so this is the perfect filter for watching the big red Flecks on the gas planet Jupiter. The rings of Saturn will be accentuated, the structures of the Venus Atmosphere will be even finer. BRESSER Filter Yellow (1,25):Watching the Moon surface through the filter, the contrasts will enormously increase. Same with planet Mars. On the huge planet Jupiter, when using the filter, you can even see the contrasts between the cloud-bands and a lot more details. Starting with a telescope diameter of 8“ and a clear sight, you even get to see various details of Saturn. 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. FEATURESVersatile colour filter set For eyepieces and accessories with 1.25" filter thread Increase contrast on moon and planets Making object details more visibleSCOPE OF DELIVERY4pcs color filter: Red, Green, Blue, Yellow
