BRESSER's Messier Newton telescope has emerged in recent years as a reliable and effective work tool, also for astronomical photography. With the new Messier NT-203s/800 with Hexafoc we can present you the new generation of these devices. Parabolic primary mirror photonewtons allow you to take deeper snapshots with the same exposure time thanks to its fast 203mm (8") f/3.9 aperture rate. The large 85mm secondary mirror provides optimal field illumination. The High-quality Hexafoc 2.5" focuser gives you vignetting-free and problem-free photography. It also has pipe clamps with a 44mm universal dovetail rail, a carrying handle with the option to mount a photographic device for a camera as well as a clear reticulated finderscope. The Hexafoc focuser can be easily expanded later with a 10:1 reduction ratio (Art.Nr.: 0625720).

Mount, tripod and handbox with computer. This German mount is equipped with guidance motors on both axes, making it easier for you to position and track astronomical objects. The Handbox with GoTo function controls the mount precisely and reliably. Precision motors on both axes allow its use with a minimum of backlash compensation in its nine possible speeds. The battery (12V) can be conveniently fixed in the tray and houses 8 D-size batteries. The mount comes equipped with a solid, highly stable steel tripod and can be loaded with optical tubes weighing up to 13 kg. of weight. The GoTo control allows you to observe the sky by pressing just one button.

With the Bresser Startracker GoTo system you will be able to observe, in just a few minutes and even if you are a beginner in this world, celestial objects whose reach would have been impossible without your GoTo. The GoTo system searches for planets, nebulae or galaxies at the touch of a button and positions your telescope automatically. The GoTo system database contains more than 100,000 ready-to-use celestial objects . Observe celestial objects with your Messier series optics with GoTo system without having to search for a long time or photograph objects with low light content that you would not have been able to reach with classic search methods.
