Description
Now all telescopes of the Bresser Messier line are equipped with a new 2.5" Hexafoc focuser, which has a positive effect on both image quality and focusing smoothness. The Bresser Messier NT-203/1000 EXOS-2 StarTracker GOTO telescope on the EXOS 2 GOTO automated mount with the new StarTracker automatic guidance system has the largest aperture diameter among telescopes of its line. In combination with a long focal length, this allows you to examine the planets of the Solar System in detail, but in no case limit yourself to this. Hundreds of galaxies, nebulae, star clusters will not hide from your eyes. In addition, this motorized telescope provides excellent opportunities for astrophotography.
The flagship line of Messier telescopes from the German manufacturer Bresser is distinguished by high build quality, precision fitting of optical elements and the use of only high-quality materials. There is no compromise in quality and price. All units, parts, and mirrors of the telescope are made with precision accuracy, which provides the best optical and operational characteristics in their class. Bresser Messier telescopes are highly appreciated by experienced amateur astronomers.

Bresser Messier NT-203/1000 EXOS-2 StarTracker GOTO is a large-aperture Newtonian reflector for visual observations and creating colorful photographs of deep space objects. An eight-inch light diameter and a modern powerful German-type equatorial mount will ensure excellent telescope operation and high-quality observation of distant star clusters, nebulae, comets, planetary rings and much more. This telescope can be used by both novice observers and "advanced" users - excellent optical capabilities and ease of use make this model universal.
The German EXOS-2 StarTracker GOTO mount is quite rigid (it can easily withstand a tube load of up to 13 kg) and is equipped with motors on both axes, which provide 8 different speeds for aiming at an object. The object is selected and the telescope is controlled using the StarTracker computer controller, which is made in the form of a hand-held remote control with buttons and a display. The mount is powered by 8 1.5 V type "D" batteries, which are installed in a suspended battery block, or by means of a separately purchased adapter connected to any 220 V AC source, or a 12 V DC source, including the vehicle's on-board network. The mount is also equipped with an optical pole finder, which allows you to prepare the telescope as accurately as possible to begin observations.
The StarTracker autoguidance system stores information on more than 100,000 astronomical objects: planets, galaxies, nebulae, stars, which is conveniently divided into several subgroups (Solar system, constellations, catalog of known stars, Messier catalog, NGC catalog, IC catalog, Sh2 catalog, catalog of bright stars, SAO catalog, objects entered by the user). If you have difficulty finding the object of interest through the finder - just select it in the computer guidance system, and the mount will do everything itself: calculate the location of the object and direct the telescope with maximum accuracy. One of the nice little things - installed red LEDs, which make it possible to use the controller remote control as an astro-flashlight.

The mounting clamp of the tube has a screw on which almost any camera equipped with a standard tripod mount can be mounted. In this way, you can get wide-angle shots of star fields, the Milky Way, the brightest galaxies and nebulae. In addition, the adapter for eyepieces from 2'' to 1.25" has a thread for connection to a T-ring, allowing you to use the telescope as a large lens for a SLR camera, devoid of chromatic aberration that distorts color rendition. The telescope kit also includes a long-focus eyepiece SuperPlossl SPL26 mm and a large optical viewfinder, a movable star chart and the Stellarium planetarium program for a personal computer, which displays the night sky with all the constellations, planets and nebulae on the computer screen for the time and place of observation selected by the user.
One of the latest improvements of the company, implemented in this telescope, is the new Hexafoc focuser with an internal diameter of 2.5". Thanks to this solution, it was possible to avoid possible vignetting (cutting) of the image when working with wide-field two-inch eyepieces. In addition, attention was paid to improving the smoothness of the movement and stability of the focusing system itself.
High image quality is guaranteed not only by the robust design, but also by the excellent quality of the parabolic mirror with highly reflective coating. All elements of the optical design of Bresser Messier telescopes are made of special optical glass. This is what allows obtaining bright and clear images of observed objects with correct color rendition, both during visual observations and during astrophotography.
