A truly versatile telescope for exploring the universe in all its facets. The moon, planets, and deep-sky objects can all be observed with ease. The OTA (optical tube assembly) continues to challenge the user to push the boundaries of their abilities and the universe. The secondary mirror has a diameter of 65mm. The OTA comes with sturdy tube rings and a vixen-style dovetail. A magnificent instrument that guarantees a visually bright, high-contrast, and color-accurate image. The telescope is also suitable for astrophotography. Taking images of the moon and planets is easily possible with this OTA. This Newtonian telescope features a parabolic mirror, resulting in a brighter image with virtually no light loss. The focuser is already equipped with a T-2 thread, allowing for the direct installation of a T-2 camera adapter. This Bresser Messier telescope is equipped with the latest HEXAFOC focuser. This focuser has a larger aperture of 2.5 inches (65 mm). This provides a larger field of view during observing and, if desired, photography. For the avid astrophotographer, an optional 1:10 ratio reduction is available. This accessory allows for very precise focusing. The telescope is equipped with a focus tube whose length can be adjusted. This allows for the easy removal of a portion of the focus tube to achieve the correct focus area for photography or visual observation.
