Gear70Q Quad Petzval Astrograph
The Gear70Q Quad Petzval Astrograph is built for astrophotographers who want wide-field deep-sky images with sharp, true-color detail from edge to edge. With a premium 4-element optical system and a fast f/5 focal ratio, the Gear70Q Quad Petzval Astrograph is designed to deliver a flat field across modern camera sensors, making it an ideal grab-and-go imaging platform for nebulae, galaxies, and star clusters.
Gear70Q Quad Petzval Astrograph Key Features
Exceptional Quadruplet Optics for a Flat Field
At the heart of the Gear70Q Quad Petzval Astrograph is a high-performance quadruplet (4-element) apochromatic refractor design engineered to minimize chromatic aberration and maximize contrast. The result is crisp stars, excellent color correction, and uniform sharpness across the image plane—no extra field flattener required for wide-field imaging.
Fast f/5 Wide-Field Performance
With a 70mm (2.8") aperture and 350mm focal length, the Gear70Q Quad Petzval Astrograph excels at capturing expansive targets. It frames popular objects beautifully and is especially well matched to APS-C and full-frame sensors, helping you capture detailed, clean data with consistent edge performance.
Built for Real-World Imaging and Travel
The Gear70Q Quad Petzval Astrograph includes a 2.5" dual-speed rack-and-pinion focuser for smooth, precise focus, plus a CAA (Camera Angle Adjuster) so you can rotate your camera to the perfect composition. A Vixen-style dovetail keeps mount compatibility simple. Every Gear series scope includes a functional carry case designed to hold accessories—place your camera and control unit inside, and enjoy a dedicated cutout that allows your focusing motor to remain installed for true grab-and-go convenience.
