BRESSER Messier 6'' Planetary Dobson Telescope
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 6 inch Planetary Dobson is something very special. Despite its low price, it offers a variety of functions and quality, which you sometimes look for in the considerably more expensive devices in vain. With an aperture diameter of 150 mm and a focal length of 1200 mm of this high quality BRESSER newtonian optics, the observation of the moon, the planets and planetary nebulae is particularly well possible.  Craters and grooves of the moon as well as the fast changing shadows cast by the so-called terminator line are exciting observation targets. Saturn with its impressive ring, Jupiter with its bands of clouds and the movement of its easily visible moons, the crescent shape of Venus and the glowing red Mars are good examples of what this telescope can be used for. Because of the long basic focal length you can easily achieve the high magnifications required for this purpose with this telescope. You do not need expensive special eyepieces. In short, this is a telescope primarily for detailed observation. Nevertheless bright deep sky objects like the Orion Nebula or the galaxies Messier 81 and 82 etc. can be observed as well. Also photography is no problem with this tube. Here is another strength of this telescope: if you want to take pictures, you can simply unscrew the altitude wheels from the tube and put them on a EQ mount with an optionally available dovetail rail - and nothing more stands in the way of astrophotography. The included eyepiece adapter has the common T2 connection thread (M42x0.75mm), to which almost every standard camera can be attached. Only the camera specific T2 adapter ring is additionally required. Of course, also common USB planetary cameras with 1.25 inch or 2 inch plug diameter can be used directly with this telescope. With the original equipment you can observe immediately - an optical 6x30 viewfinder and a 25 mm SPL eyepiece are included. For those who want to transport the device as compact as possible, the new 6'' BRESSER Messier Planet Dobson makes it very easy - the rocker box can be disassembled in a few easy steps, because the parts are assembled with metal quick connectors. So a bulky rocker box quickly turns into a handy flat package of boards. A telescope whose versatility, performance and user-friendliness set new standards in this price class. Please note that Newtonian reflector telescopes are very good for astronomical observations of the starry sky, but are not well suited for observing nature and landscapes during the day. For nature and landscape observations we therefore recommend BRESSER lens telescopes.

BRESSER Messier 8'' Dobsonian
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 8'' dobsonian is simply a breakthrough. Despite of its low price this telesccope offers a versatility and quality rivaling a lot more expensive telecopes. The optical diameter of 203mm (8'') 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. With that telescope those objects are beginning to show structures: globular clusters are no longer only fuzzy blobs, but are resolved into masses of individual stars. Nebulae, that can only be barely detected in smaller scopes, reveal structures within. The telescope is setting a new standard in versatility: the excellent Hexafoc focuser boosts a free diameter of 65mm (2,5'') so that you do not have vignetting in big widefield eyepieces that is caused by smaller focuser barrels. The big altitude wheels handle those big, heavy eyepieces without problems - and when you intend to load even more (like a binocular viewer with two eyepieces) then you can move the tube in its tube rings and achieve balance within seconds. The excellent rigidity of the focuser makes focusing a snap - even for astrophotography. This is another virtue of this highly versatile telescope system: you can remove the altitude wheels from the tube rings, attach a dovetail and use the optical tube on a equatorial mount for astrophotography - in minutes. The focuser is handling even heavy cameras tilt and shifting-free. You are extremely demanding in your image sharpness? No problem - with the optional 10:1 gear reduction sharp images are easy. If you consider, that the focuser is that part of the telescope that is used most often, you will recognize the quantum leap this Hexafoc represents in a telescope of this price range. With the included standard accessories (6x30 finder and 25mm SPL-eyepiece) the telescope is ready for observing. If you need to transport or store the telescope as compact as possible you will like this: the rocker box of the 8'' BRESSER Messier assembles and disassembles extremely easy and fast due to the use of metal standard furniture fasteners. So you can transform the bulky rocker box into a handy flat package of boards. 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.

BRESSER Messier 10" Telescope Dobson
NEW - now including a high-quality lens solar filter for the safe observation of sunspots, eclipses and planetary transits. A high quality telescope for night and solar observation.The BRESSER Messier 10 "Dobsonian is something very special. Despite the low price, it offers a variety of functions and quality that are sometimes unavailable in considerably more expensive telescopes. With its 254 mm diameter optics, this telescope is not limited to solar system observation of the Moon and brighter planets - you can also observe far out into the universe and see globular clusters, nebulae and galaxies. Details become visible in most deep-sky objects: globular clusters are broken down into individual stars and nebulae, which are only hinted at in smaller scopes, show considerable structure. This Dobsonian is unsurpassed in versatility within its price range: the excellent, large Hexafoc focuser has an opening of 65 mm - so even with large wide-field eyepieces, there is no noticeable vignetting from the eyepiece extension tube. The large elevation wheels also hold the telescope level with just the right amount of "sticktion", even when heavier eyepieces are used. And when a lot of heavier accessories are attached, such as the Bresser Binoviewer attachment, then the entire telescope tube can be moved within the tube rings - and everything is balanced again in a flash. The unsurpassed rigidity of the focuser makes it easy to focus - photography with this OTA is no problem either as the supplied extension tube for the focuser can be removed and a camera easily bought to a prime focus position. This is another strength of this universal telescope: if you want to take photos, you can simply unscrew the elevation wheels from the tube and place it on an equatorial mount with a standard dovetail rail - other rival Dobsonians do not offer this level of flexibility or pathway to more expansive astrophotography use. An optional dual speed 10:1 gear reduction for the focuser is available for those who need extra fine control of focus. If you consider that the focuser is the telescope part that is used most often, the supply of the Hexafoc on this telescope is a quantum leap for this price range.With the initial equipment you can observe immediately - a 6x30 viewfinder and a 25mm SPL eyepiece are included within the package.  If you want to transport the device as compactly as possible, it is easy with the new 10 "BRESSER Messier - the rocker box can be dismantled in a few simple steps, as the parts are assembled with metal quick-release connectors. A bulky rocker box quickly becomes a handy flat package of boards within a few minutes. This is a telescope whose versatility, performance and ease of use set new standards in this price range.Please note that while Newtonian type reflecting telescopes are very good for astronomical observations in the night sky, they not well-suited for observing nature and landscapes during the day. We therefore recommend BRESSER refracting or Cassegrain designs of telescopes for additional nature and landscape observations.PROPERTIESType: mirror telescopeMirror diameter: 254mm / focal length: 1270mm / F / 5Maximum useful magnification: 508 timesTelescope for night and solar observation2.5" HEXAFOC focuserMain mirror made of special glass, with low thermal expansionHassle-free focusing, even with heavy accessoriesEasy to move tubeDismountable rocker boxTube mounting on altitude bikes using clampsUse of the optics on other mounts as wellAdjustment and construction screws of different sizesBase diameter 54cmWhat's IncludedTube with Newtonian opticsFull aperture Solar filter6x30 viewfinder25mm Super Plössl eyepiece (Ø 31.7 mm / 1.25 ")1 extension tube 37.5mm for 2.5 " Hexafoc1 eyepiece adapter 1.25" to 2"/31.7 to 50.8 mm2 Tube Rings2 Altitude support wheelsRocker box with 2 base plates and mounting material (disassembled for self-assembly)Shipping dimensions Box1: 134x44x44cm - 19.0kgShipping dimensions Box2: 61x61x24cm - 17.0kg

BRESSER Messier 6" Dobson
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 6'' dobsonian is simply a breakthrough. Despite of its low price this telesccope offers a versatility and quality rivaling a lot more expensive telecopes. Not only for beginners - also enthusiastic and experienced amateur astronomers love this high perfomance 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 6'' 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 6'' 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 150mm (6'') 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 parabolic main mirror which offers a much better scharpness and contrast than other telescopes with a simple spherical main mirror. In addition, this telescope has a particularly large secondary mirror of 55mm in diametre for ideal illumination of the image field. The 6'' Dobsonian is also equipped with a large 2.0'' focuser, which allows the use of 2.0'' eyepieces with even larger fields of view. Due to the included eyepiece adapter 2'' to 1.25'', all 1.25'' eyepieces can of course be used. 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 - in minutes. 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.

EXPLORE SCIENTIFIC Zero X Field Flattener 2''/M48 for ED80, ED102 and ED127 APO
Field flattener without reduction factor for Explore Scientific ED80 , ED102 and ED127 APO Refractors The imaging plane of many telescopes is not flat but curved. This means that only the area in the centre is perfectly focused - the edge becomes blurred. The human eye can usually compensate for this image property, but a camera shows increasing blurriness towards the edge of the image field. The Explore Scientific Zero X field flattener eliminates the field curvature in many telescopes with a focal length of approx. 480 to 952 mm. The Zero X field flattener was calculated and developed for Explore Scientific ED80, ED102 and ED127 apochromats with focal ratios of F=6.0 and F=7.5. The image sharpness at the edge is dramatically increased. The stars appear round and no longer distorted - a clear benefit for the whole image aesthetics. The Zero X image flattener can be used not only with Explore Scientific Apos, but also with many other Apos. This flattener does not change the focal length of the telescope. Correction for up to full-frame camera sensors (24x36mm) The Explore Scientific Zero X image flattener has been developed due to the rapid development of ever larger camera sensors. With it, there is finally a field flattener available that illuminates and corrects the field of view for full-frame camera sensors up to 24x36 mm. How to use the Zero X field flattener with M48 thread connection This field flattener has a 2 inch (50.8 mm) plug-in connection on the telescope side, with which it is inserted into the telescope instead of an eyepiece or star diagonal mirror. On the camera side, there is a standardised M48 x 0.75 mm connection thread. This M48 connection thread offers a larger free inner diameter than the usual T2 (M42) thread and prevents vignetting when using large camera sensors. With an optionally available and camera-specific adapter ring, a DSLR camera can be connected to it. The working distance is already set at 55 mm. Of course, mirrorless cameras or special astro cameras can also be used with the M48 thread connection. For this, the appropriate M48 spacer sleeves or adapters are additionally required to set the right working distance of 55 mm. This must always be done with every corrector or field flattener so that the best possible field flattening is achieved.Filter thread on telescope side availableThe telescope-side 2.0 inch plug-in sleeve has an M48x0.75 filter thread (internal thread). Individual 2.0 inch colour or nebula filters can be inserted here to increase the contrast of the images.FEATURESField flattener for Explore Scientific ED80, ED102 and ED127 APO telescopesRemoves field curvature from telescopesProduces round stars even at the edge of the image fieldImage sharpness at the edge is drastically increasedA clear benefit for the whole image aestheticsCorrection of field curvature for up to full-frame camera sensors (24x36 mm)Image field flattener without reduction factorOn the telescope side with 2 inch (50.8 mm) plug-in connection and M48x0.75mm filter threadCamera side with large M48 threaded connectorWorking distance of 55 mm between field flattener and camera sensorFor telescopes with a focal length of approx. 480 to 952 mmOptimised for telescopes with focal ratios from F=6.0 to F=7.5Can also be used for various other APOsFully multi-coating on all lens surfacesHousing made of lightweight aluminium, black anodisedAluminium dust cap for M48 threadSCOPE OF DELIVERYZero X field flattener (1 piece)Dust caps
