Bresser Messier AR-152S 152/760 HEX EXOS EQ-5

The Messier AR-152S optical tube is a top-notch achromat refractor designed for those who are passionate about advanced visual observations and astrophotography. With a generous lens diameter of 152 mm and a focal length of 760 mm, constructed using a Petzwala type design with four lenses, this telescope offers exceptional performance. Despite its significant light-gathering ability, it boasts a remarkably flat field of view. Whether you're observing planets or the Moon, this telescope excels at revealing intricate details on the surfaces of objects within our Solar System. Among deep-sky wonders, it unveils hundreds of nebulae from both the Messier and NGC catalogs, providing breathtaking views. Furthermore, the optics are fully coated with anti-reflective layers (MC) to ensure optimal image quality.

One of the standout features of this telescope is its Hexfoc focuser, featuring a unique hexagonal profile corresponding to a 2.5-inch diameter. This innovative design imparts exceptional rigidity, unmatched in its price range. Additionally, the focuser can be extended with a 10:1 precision focusing module, allowing you to operate even heavier equipment and accessories without any concerns about deflection or loss of axial alignment. The substantial diameter also naturally minimizes vignetting, providing a seamless viewing experience.

The Messier AR-152S is the ideal choice for seasoned sky observers, thanks to its remarkable optics and sturdy build. Mounted on the outstanding EXOS-2/EQ-5 mount, it offers extensive opportunities for amateur astrophotographers.
