Product description

More about the series Messier...

The traditional company Bresser offers telescopes for ambitious beginners at an excellent price-performance ratio under the name Messier. The Messier telescope systems are expandable and retrofittable, so they can be used far beyond the initial entry point.

The NT203s/800 optics: The Newtonian telescopes of the Messier series have established themselves in recent years as reliable workhorses even for astrophotography. With the new Messier NT203s/800, the series undergoes a further improvement that astrophotographers will appreciate.

  • Thanks to its fast aperture ratio of f/3.9, the Newtonian with parabolic primary mirror allows deeper exposures with the same exposure time.
  • The large secondary mirror ensures optimal field illumination.
  • The high-quality 2.5" Hexafoc focuser ensures vignetting-free photography.
  • Elaborate 6-point main mirror bracket
  • Large adjusting screws for main and secondary mirrors

Tube clamps with 44mm dovetail rail and carrying handle with mounting option for a camera, as well as an excellent bright viewfinder with crosshairs, complement the image of these high-quality units.

The mounting Bresser EXOS-2:

The EXOS-2 is a robust mounting with high bearing capacity (up to 13 kg visual, 10 kg photographic) and precise setpoint tracing for visual watchings and for astro-photography.
Double radical rill-bearings make the function precise and the optimated RA-axes don´t let much play. Further, the very robust, precise worked mounting allows an easy entrance in astro-photography. A motorical 2-axes control can be added.

includes:

  • robust mounting
  • agreed counter weight
  • robust 3-leg tripod made of steel

The GoTo system for the EXOS 2 from Bresser helps even beginners to observe celestial objects, which would be very difficult or impossible to find without GoTo, in just a few minutes. By simply pressing a button, the GoTo system slews the telescope to the planet, nebula or galaxy you have selected and tracks it fully automatically. The database contains over 100,000 objects. You can observe celestial objects with the Messier series GoTo telescope without long searches, or photograph faint objects that you would not even be able to find using classical location methods!

It not only matters which telescope you buy but also where you buy it. Our additional services:

  • We are a leading telescope dealer and know the devices we sell. Our customer service team will gladly help you after your purchase if you have problems with assembly or operation.
  • We provide a copy of the 80-page Telescope ABC beginners handbook with every telescope.
  • We also provide an edition of the exciting astronomy magazine, “Sterne und Weltraum” with each telescope.
