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.

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.In the past few years the Bresser Newton telescopes have become the standard workhorse for Deep Sky astrophotography. We now proudly present the second generation of this telescope, the Bresser NT-203s/800 with Hexafoc and a fast parabolic main mirror. The Bresser NT-203s/800 f3.9 will deliver you deeper images due to its - compared to 8" f/5 systems - oversized primary mirror and therefore faster optical system with the same exposure time. The big 85 mm secondary prevents vignetting for optimal illumination The excellent 2.5" Hexafoc focuser also does not cause vignetting due to its large diameter and makes focussing a joy - the smoothness and shifting-free operation sets new standards in this price class. This groundbreaking focuser, tube rings with 44mm universal standard dovetail and camera mounting feature and a high-end finderscope with haircross and laser-engraved scale  leave nothing to desire even for demanding astrophotographers. The NT-203s/800 Hexafoc has a classical tube construction with an aluminium tube. The focuser can be upgraded with a 10:1 reduction (part No. 0625720) without problems. Ready to use with the  HR Coma Corrector (part No. 0510330) which eliminates coma, field-curvature and astigmatism.Please note: Reflector telescopes with optical design Newton are very good for astronomical observing at the starry night sky.

Who doesn't dream of exploring the vastness of the universe with their own eyes? This complete telescope set comes with everything you need for your journey to open star clusters and distant emission nebulae: an astronomical reflecting telescope with 114 mm aperture and 500 mm focal length, an equatorial mount, a tripod and extensive accessories for astronomical observations. You can immediately start your very own adventure in astronomy, because the system is very easy to handle and transport. Especially wide-field observations in the Milky Way are a joy to watch through the beginner's telescope. A classic for a start - the telescope With the classic reflector telescope, a so-called Newtonian reflector, you’ll achieve a successful start in sky observation. A special feature of this type of telescope is that you don’t look in at the back of the telescope, but at the side in the front. The advantage is the comfortable observation position. So you don't have to bend down when the entry-level telescope is pointed vertically into the sky. In terms of optics, these reflecting telescopes are impressive in that they are absolutely free of chromatic aberrations and offer good imaging properties.  With its 114 mm aperture, the entry-level telescope already collects a lot of light from celestial objects. In addition, 114 mm aperture and 500 mm focal length result in a very short focal ratio (ratio of the aperture to the focal length) of about 1 to 4.4 (F/4.4). This causes the telescope to be very fast and to deliver an extremely bright image. The fast focal ratio and the short focal length cause the telescope to be a specialist for observing structures in the Milky Way and extended gas nebulae, for example the North America Nebula NGC 7000. This way a ''walk'' through the Milky Way with low magnification is simply a lot of fun. And you can choose the perfect place for it, because the entry-level telescope is very compact and therefore easily transported. And how closely will you be able to look? The aperture of 114 mm offers a resolving power that allows magnifications of up to about 230x with sharp images. Technically, even higher magnifications are possible - theoretically up to 375x by using the included accessories. However, as the magnification increases, the sharpness of the image may slowly decrease. Of course, it is not only your telescope that determines how much you can magnify. The air turbulence in the atmosphere (seeing conditions) is also an important factor. Note for nature lovers: If you choose a Newtonian telescope like the Pluto reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed sideways 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 observations during the day. Would you also like to use your new telescope for exciting nature discoveries? Then we recommend that you choose one of the BRESSER refractor telescopes. The perfect foundation for your astro-start - mount and tripod Have you found the ideal location for your celestial observations? Then simply attach the telescope tube to the height-adjustable tripod with equatorial mount. It makes tracking particularly easy, because in contrast to an azimuthal mount, you do not need to move both axes at the same time. So you simply align one axis parallel to the Earth's axis by pointing it approximately at Polaris. This process is called ''alignment''. After that, you track your celestial bodies only on this one axis. Another plus of the mount are the two flexible shafts with fine adjustment. They make adjusting and tracking the beginner's telescope particularly precise and comfortable. Very handy: A storage plate mounted between the tripod legs allows easy access to your accessories.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! Everything included - the accessories Unpack, set up and start your journey of discovery across the night sky right away – for this purpose the astronomy set comes with all the necessary accessories. Get the perfect overview with the LED viewfinder. To do this, the viewfinder is simply installed parallel to the actual telescope. Turned on, it projects a red dot onto a small ground-glass screen. Look through it and it appears to hover in front of the night sky in exactly the direction in which you have aligned your entry-level telescope. Thus precise telescope alignment and finding celestial objects becomes child's play when you are using the LED viewfinder. A larger field of view or more details? With the two eyepieces (4 mm and 20 mm) you can admire the objects in different magnifications. The 3x Barlow lens goes one better: it allows you to triple the magnification of the eyepieces. But it doesn't have to stop there: If you ever want to expand your astronomy set, you can choose from a variety of additionally available eyepieces. After all, the socket diameter of 31.7 mm (1.25 inch) follows an international and manufacturer-independent standard. Observe the star of our daytime sky completely safely – to this end a solar filter is included with the entry-level telescope. Take a closer look at the sunspots and marvel at the granulation on our very own star. CAUTION: Never point the telescope at the Sun without the solar filter! For quick snapshots of special discoveries, grab the smartphone camera adapter. This way you can delight yourself and your friends again and again with fascinating astrophotos, for example of the Moon or the Sun.
