125mm f/2 Honders Advanced Catadioptric Astrograph

THE ULTIMATE GRAB-AND GO ASTROGRAPH !!

The all-new Honders Advanced Catadioptric, or HAC125DX Minigraph is the smallest, fastest astrograph you can find.The Honders Advanced Catadoptric optical design maximizes its glass with hybrid refractive and reflective surfaces to deliver the sharpest, fastest, lightest catadioptric mini astrograph (minigraph) available.The Sky-Watcher Honders Advanced Catadioptric (HAC) telescope is a sophisticated, high-speed astrograph designed for fast, wide-field imaging in a compact and lightweight package. Unlike other small refractor astrographs, the HAC125DX features a lightning-fast f/2 focal ratio allowing you to capture images 5x faster than a standard f/4.9 optic. With this kind of speed that means more data in less time and no need to autoguide!

The TS 10" f/8 Ritchey-Chrétien Astrograph is a dream telescope for astrophotography.

• Aperture 10" / 250 mm
• Focal length 2000 mm
• Focal ratio f/8
• Hyperbolic primary and secondary mirror for very high sharpness on the optical axis and a large well-corrected field for astrophotography
• Mirrors made of fused silica for stable focus position
• 94% enhanced reflectivity on main and secondary mirror for an even brighter image
• Quicker cooling down thanks to open construction and primary mirror ventilation
• Two Losmandy style dovetail bars supplied - ideal for accessories like guiding scopes or a piggyback camera mount
• Carbon truss tube - more rigidity and better focus stability for astrophotography
