BRESSER Messier 12" Dobson Telescope

The new BRESSER Messier 12" Dobson now expands this popular series of telescopes and, thanks to its lightweight GRP telescopic tube, is also easy to transport.

Despite its low price, this telescope offers a variety of features and quality that is sometimes sought in vain in much more expensive devices. With the powerful 305 mm telescope aperture, you get greater light-gathering capacity than with smaller models, and you are not limited to observing the Moon and planets of our solar system: you can look deep into the universe and observe star clusters, nebulae, and galaxies with even greater brightness. In this way, details in most deep-sky objects are visible: star clusters are clearly resolved into individual stars and gas nebulae, which can only be hinted at with smaller devices, show structure.

This device is incomparably versatile: The excellent and large Hexafoc focuser has an aperture of 65 mm - so even with large wide-angle eyepieces, there is no shadowing by the focuser tube.

Thanks to the large altitude wheels, even these heavier eyepieces remain stable. And if a lot of accessories are ever mounted, such as a binocular attachment, then the entire tube can be shifted in the clamps - and everything is quickly rebalanced. The unparalleled rigidity of the focuser makes focusing easier - so even photography with this tube is not a problem.

This is another strength of this universal telescope: Anyone who wants to take pictures can simply unscrew the altitude wheels from the tube and mount it on an equatorial mount with a dovetail. And nothing else stands in the way of astrophotography. For higher demands, an optional 10:1 gear reduction is available for the focuser. If the focuser is considered the most used part of the telescope, then the use of the Hexafoc in this device represents a quantum leap for this price range.

With the initial equipment, observation can begin immediately - a 6x30 finder and a 25 mm SPL eyepiece are included with the device. Thanks to the 2 standard hybrid finder holders (Art. 0620158), several other types of finders can also be equipped.

Those who want to transport the device as compactly as possible will also find it easy with the new 12" BRESSER Messier: The rockerbox can be disassembled in a few steps, as the parts are assembled with quick-release metal connectors. Thus, a bulky rockerbox quickly becomes a flat and manageable package of individual parts.
