PASSION™ HD products represent the absolute premium class from GPO. HD optics design combined with state-of-the-art multi-layer coatings creates optical excellence in transmission, field of view, edge-to-edge sharpness, close focus and color rendition.

The ESATTO 4" is the large dimensions robotic microfocuser that we designed for observatory class telescopes or for astrographs that need for large free aperture, like the Takahashi FSQ-106.

For the price-sensitive planetary observer the AR-127L is a dream machine. The combination of large aperture and long focal length provides tack-sharp high-contrast pictures that will impress you every time anew. The rock-solid mount provides relaxed views even at high magnifications; rigidity and usability are setting new standards in this price range.

The ZEISS Conquest HDX combines superior optical performance, robustness and ergonomics at an extremely attractive price, making it the ideal all-rounder in the premium optics range.

The combination of large aperture and short focal length predestine the MESSIER AR-152S for the observation of large celestial objects. The compact size of the MESSIER AR-152S combines outstanding tranportability, high light gathering power and low weight for a telescope of this aperture.

The MESSIER MC-152 excells due to its compact optics and low weight. The long focal length of this telescope facilitates relaxed observations with high magnifications

The Calcium Quark brings quick, easy fun of the Original Quark to Calcium H-Line.
For use on refractors of F/7 or longer focal ratio refractors.

The same kit as the FS-60CB but with a 1.7x extender module to increase the focal length to 600mm. The module can be removed converting it back to a FS-60CB for ultimate versatility.
