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!

• 40x magnification for high detail resolution
• Large exit pupil for bright image even at the onset of twilight
• Rubber-armored, waterproof and nitrogen-filled - robust and fog-free
• Single eyepiece focusing for individual focusing
• Porro prisms provide a "spatial impression" even at longer distances
