UNIVERSITY OF OXFORD compact telescope (Refurbished)

Thanks to fully multi coated Bak-4 glass material and the extra large objective lens diameter the BRESSER Spezial-Astro 20x80 Porro Binoculars provide bright, crisp images from edge to edge. Their high 20x magnification makes these excellent binoculars convenient not only for observing astronomical objects, but are also practical for viewing distant terrestrial targets and nature study. Their optical design and coatings minimise stray light and ghosting (even near brighter objects like the Moon), which would otherwise disrupt and detract from observing enjoyment.Diopter compensation and foldable rubber eyecups give wearers of glasses the possibility of making the best use of these binocular's wide field of view. With the tripod thread integrated in the strong central support column, which is adjustable along the centre axis bar, the BRESSER Spezial-Astro 20x80 Porro Binoculars can directly be mounted onto any suitable camera-style tripod and balanced front to back, once in place.FEATURESBinoculars for astronomical and long distance observationsExtremely high light gathering capacityCan directly be mounted onto tripods with standard 1/4" attachmentsWHAT'S INCLUDEDBinocularsCarry case

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.
