About Sky-Watcher HAC125 DX 125mm f/2 Minigraph 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 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!

Compared to the original HAC125 the HAC125DX features a rear focusing mechanism on the primary. This allows for a wider range of cameras to be used compared to the original model and makes focusing easier when the telescope is in use. The telescope features a 16mm image circle which is ideal for IMX533 and 585 cameras. While small, at only 15.7" long the HAC125DX offers a powerful imaging platform for both beginners and advanced imagers.

The HAC125DX is the ultimate grab-and-go astrograph. Fast optics and small size make it easier to get out and enjoy the hobby you love. Attach it to your favorite portable mount and you are ready to capture the universe in virtually no time at all! The HAC125DX is not just another astrograph, it's a Minigraph that is ready for all your astronomy adventures.
