Bresser Messier Dobson telescope with parabolic primary mirror and 2.5" HEX-focuser

The Bresser Messier 8" dobsonian is simply a breakthrough. Despite its low price, this telescope offers a versatility and quality rivaling much more expensive telecopes. The optical diameter of 203mm (8") does not restrict your observations to solar system objects like the moon or the planets - you can reach further into the sky and explore globular and open clusters, nebulae and galaxies. With this 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. This telescope sets 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 large, heavy eyepieces without problems - and when you intend to load even more (like a binoviewer 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. Another virtue of this highly versatile telescope system is that you can remove the altitude wheels from the tube rings, attach a dovetail and use the optical tube on a equatorial mount for astrophotography - all in minutes. The focuser is capable of 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 (LED-finder and 25mm SPL-eyepiece) the telescope is ready for observing straight out of the box (though we'd naturally recommend additional eyepieces).If you need to transport or store the telescope as compact as possible you will appreciate this particular part of the Bresser 8-inch Dobsonian's design: the rocker box of the 8" Bresser Messier assembles and disassembles extremely easy and quickly due to the use of metal standard furniture fasteners. Thus, you can transform the bulky rocker box into a handy flat pack in no time at all.

This telescope is setting a new standard in usability, versatility and performance in its price class.
