Bresser Messier 10" Dobson

Bresser Messier 10" Dobson

The Bresser Messier 10" 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 254mm (10") 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 the majority of
those objekcts are showing 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 excellen
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 dovetails 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 10" Bresser Messier assembles and
dissassembles 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.
