Discover the 130PHQ: the ideal long-focus astrograph for astrophotography

The 130PHQ is a long-focus, flat-field astrograph designed to simplify the astrophotographer's experience while delivering outstanding image quality. No need to buy additional field correctors or spend time calculating backfocus and adjusting complex connections: the 130PHQ is ready to use with any type of imaging device, keeping the target in perfect focus. This revolutionary telescope makes celestial image capture accessible and uncompromising.

Technical specifications of the 130PHQ

• Aperture and Focal length : With an aperture diameter of 130 mm, the 130PHQ offers a focal length of 1000 mm, i.e. a focal ratio of f/7.7, perfect for capturing precise details in the night sky.
• Quadruplet optical system with ED lenses : Featuring an APO quadruplet lens (with two ED glass lenses), the 130PHQ perfectly controls chromatic aberrations and other optical distortions. Its self-plating design guarantees sharp, uniform images across the entire field of view.
• 60 mm image circle : Designed for medium-sized sensors, the 60 mm image circle offers extreme precision with minimal distortion of peripheral stars and a central RMS radius of less than 2 microns.
• Field Reducer (Optional) : Used with the 3” 0.7x field reducer, the 130PHQ achieves a focal ratio of f/5.4, reducing the focal length to 700mm and enabling shorter exposure times.

Construction and Accessories Included

• High-end design : The 130PHQ is CNC machined, with high-quality painted tubing and attractive aesthetic finishes. The telescopic sunshade and decorative parts add a touch of sophistication.
• 3.4” Rigid Focuser: Equipped with M68, M54 and M48 adapters, as well as a finder base, this industrial-grade focuser ensures optimum stability and precision.
• Multifunctional handle : The handle features a central slot for an M6 screw, allowing flexible and convenient configurations. The 130PHQ also includes a standard Losmandy dovetail plate and robust double rings for stable use, whether for observation or imaging.
