Thanks to its high light-collecting power, the Bresser Messier NT-203 telescope is designed for observing deep space objects such as nebulae, galaxies, star clusters and comets. It is also an excellent instrument for observing planets. The ability to obtain large magnifications allows you to enjoy breathtaking subtle details on their surfaces. The large, flat field of view predisposes this instrument to take beautiful photos of the starry sky.

The telescope is equipped with a new Hexfoc eyepiece focuser. The geometric design of the focuser is based on a hexagonal profile with a diameter of 2.5". Thanks to this solution, the effect of unwanted shifting of the focuser sleeve has been eliminated, especially when installing heavy accessories. Additionally, the focuser construction uses adjustment modules that correct any shifting of the inner sleeve and allow for unambiguous determination of its position.

These solutions have allowed for exceptional smoothness of movement and a high level of rigidity unseen in this price range. Even relatively heavy cameras and accessories can be operated without tilting or slipping. The large 2.5" diameter significantly reduces vignetting.

The extension tube can be expanded with a precise focusing module with a 10:1 ratio.

Thanks to this equipment, the Bresser Messier N203 is an excellent instrument for astrophotography.
