Bresser Messier AR-152S 152/760 Petzval OTA / Hexafoc + solar filter (SKU: 4852760)

The Messier AR-152S optical tube is a top-tier achromat refractor designed for advanced visual observations and astrophotography. It features a 152 mm diameter lens with a 760 mm focal length, constructed with four lenses in a Petzval configuration. This design ensures a large, flat field of view despite its substantial light gathering ability. The telescope excels in observing planets and the Moon, revealing intricate details on these celestial bodies. It also allows for the observation of hundreds of nebulae from the Messier and NGC catalogs, thanks to its high-quality optics fully coated with anti-reflective layers.

A standout feature is its new Hexfoc eyepiece focuser. With a hexagonal profile, it boasts a 2.5-inch diameter, offering unprecedented rigidity in its price range. The focuser can be enhanced with a 10:1 precision focusing module, ensuring stability and accuracy even with heavier equipment. Its large diameter also minimizes vignetting.

This telescope is highly recommended for seasoned sky watchers. It can be mounted on any mount with an EQ-5 stiffness class or higher, using a standard dovetail connection.

Key Features:

• Optical System: Durable and efficient with a timeless tube design.
