BRESSER Messier 8 "Dobson

BRESSER Messier 8 "Dobson
The BRESSER Messier 8 "Dobson is something very special. He offers a variety of function and quality looking in vain in part significantly more expensive devices despite the low price. With the appearance of measured by 203 mm, the observation not on the Moon and the planets of our solar system is limited - you can look beyond already far into the universe and observe globular cluster, Nebula and galaxies. This first details in the deep-sky objects become visible:
Globular cluster be resolved into individual stars and gas fog, which can only be anticipated with smaller devices, show structure. While the device is unsurpassed versatile: the excellent large Hexafoc eyepiece extension has an opening of 65 mm - so no shading through the eyepiece extension tube is noticeable at large wide field eyepieces. The large height wheels holds also these eyepieces without problems - and if even much of accessories is attached, such as a binocular deposits, then the whole tube in the pipe clamps can be - moved and fast everything is balanced . The unmatched stiffness of Fokussierers makes focusing easy - so also the photography with this tube is not a problem. Here is an additional strength of this universal telescope: who wants to take pictures, can simply unscrew the elevation wheels from the tube and place on a parallactic mounting with a dovetail rail - already nothing in the way of astrophotography. An optional 10:1 gear reduction for the Focuser is available for highest demands. When you consider that the Focuser is part of the telescope that is used most frequently, the usage of the Hexafoc this device is a quantum leap for this price class.
With the original equipment can now be observed - a LED Sucher and a 25 mm SPL eyepiece are supplied with the unit.
Who wants to carry the device as compact has it at the new 8 "Bresser Messier light - the rocker box can be disassembled with a few simple steps, because the parts with metal quick connectors are used together. So, a handy flat pack of boards is a bulky rocker box quickly.
A telescope which versatility, performance, and ease of use set new standards in this price class.

BRESSER Messier 8 "Dobsonian

BRESSER Messier 8 "Dobsonian
The BRESSER Messier 8 "dobsonian is simply a breakthrough. Despite of its low price this telesccope offers a versatility and experiment telecopes quality rivaling a lot more. 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 of imagezoom boosts a free diameter of 65mm ( 2.5 "") so that you do not have vignetting in big widefield taschenlampe that is caused by smaller imagezoom barrels. The big altitude wheels handle those big, heavy taschenlampe without problem - and when you intent to load even more (like a binocular viewer with two taschenlampe) then you can move the tube in its tube rings and achieve balance within seconds. The excellent rigidity of the imagezoom 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 ring, attach a dovetails and use the optical tube on a equatorial mount for astrophotography - in minutes. The pleasure is handling even heavy cameras tilt and shifting-free. You are demanding extremely sharpness in your image? No. problem - with the optional 10:1 gear reduction sharp images are easy. If you consider, that the pleasure is that part of the telescope that is used most often, you will recognize the quantum leap this Hexafoc price range represents in a telescope of this. With the included standard accessories (LED 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 want like this: the rocker box of the 8 "BRESSER Messier assembles and dis assembles extremely easy and fast due to the use of metal standard furniture fasteners. So you can transform the bulky rocker box into a mobile flat package of boards. This telescope is setting a new standard in usability, versatility and performance in its price class.
