Bresser Telescope N 203/800 Messier NT 203S Hexafoc EXOS-2 GoTo (53319)

Bresser, a traditional company, offers telescopes for ambitious beginners under the Messier brand, combining excellent performance with great value. Messier telescope systems are expandable and can be upgraded, allowing them to be used long after the initial learning phase.

NT203s/800 Optics:
Newtonian telescopes in the Messier series have become known as reliable tools, even for astrophotography. The new Messier NT203s/800 further improves the series, offering features that are especially valuable to astrophotographers.

• The fast aperture ratio of f/3.9 and parabolic primary mirror allow deeper exposures in less time.

• A large secondary mirror provides optimal field illumination.

• The high-quality 2.5" Hexafoc focuser supports vignetting-free photography.

• Six-point main mirror bracket for stable positioning.

• Large adjustment screws for easy alignment of main and secondary mirrors.

Tube clamps with a 44 mm dovetail rail, a carrying handle with a camera mounting option, and a bright finderscope with crosshairs complete the quality of these telescopes.

Bresser EXOS-2 Mount:
The EXOS-2 mount is robust and offers high bearing capacity, supporting up to 13 kg visually and 10 kg for photographic use. Double radial ball bearings ensure precise movement, while the optimized right ascension axis reduces play. The mount is solid and precisely manufactured, making it suitable for starting astrophotography. A motorized two-axis control can be added if desired.

• Strong mount

• Matching counterweight

• Durable three-legged steel tripod

GoTo System for EXOS-2:
The GoTo system allows even beginners to find and observe celestial objects within minutes. By pressing a button, the system automatically moves the telescope to the selected planet, nebula, or galaxy and tracks it. The database contains over 100,000 objects, allowing you to observe or photograph faint targets that would be difficult or impossible to locate manually.
