There are three basic kinds of scopes - refractors, reflectors and Cassegrains.

Shifting-free focusing, even with heavy accessories Primary mirror out of special-purpose glass with little thermal expansion Telescope for night and solar observation Mirror diameter: 203 mm / focal length: 1218 mm / F/6 Therefore we suggest BRESSER refractor (lens) telescopes for landscape and nature observing. But these telescopes are not well usable for observing landscape and nature during daylight. Please note: Reflector telescopes with optical design Newton are very good for astronomical observing at the starry night sky.
This telescope is setting a new standard in usability, versatility and performance in its price class. So you can transform the bulky rocker box into a handy flat package of boards. 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. With the included standard accessories (6x30 finder and 25mm SPL-eyepiece) the telescope is ready for observing. 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. You are extremely demanding in your image sharpness? No problem - with the optional 10:1 gear reduction sharp images are easy. The focuser is handling even heavy cameras tilt and shifting-free. 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 excellent rigidity of the focuser makes focusing a snap - even for astrophotography. 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 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.
Nebulae, that can only be barely detected in smaller scopes, reveal structures within. 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. 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. Despite of its low price this telesccope offers a versatility and quality rivaling a lot more expensive telecopes. The BRESSER Messier 8'' dobsonian is simply a breakthrough. Great telescope for night and solar observation. NEW - now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits.
