Blazing Fast Optical Design
The shining center of this stellar scope is the Honders-Advanced Catadioptric(HAC) optical design. Utilizing a mix of reflective, refractive components,and a front camera placement that forgoes folding the light path again likeother common catadioptric designs, this design is able to deliver anincredibly fast f/2 focal ratio to your camera. This makes the Sky-WatcherHAC125DX Mini Astrograph able to capture images of the same brightness not 3x,but about 3.7x to 5x faster than other popular compact telescopes that sport focal ratios around f/5, depending on how much additional obstruction your camera of choice adds.Realize a significant speed boost with small cooled sensor* or “puck-style” cameras,or maximize your data collection with mini form factor imaging equipment!The HAC optical design has corrective optics built-in as well, meaning thatthe bright images it forms are also superbly sharp. This advancedconfiguration is also very compact, which combined with its outstandingimaging performance create what Sky-Watcher calls a mini astrograph—orminigraph for short!
Please Note: The included M42 adapter features internal and external threading, with 6.5 mm and 12.5 mm backfocal requirements respectively. With normal native camera backspacing conventions this will limit cooled camera compatibility to options like the ZWO ASI533MM/MC Pro camera which can accommodate this adapter and backspacing with the 11 mm thread spacer removed.

Speedy 125 mm Optics
The Sky-Watcher HAC125DX Mini Astrograph features a 125 mm aperture feeding the novel Honders-Advanced Catadioptric optical design. This HAC prescription takes the almost 5″ of light gathering power and bounces it off the Radiant Aluminum Quartz (RAQ)™ coated Mangin mirror to the HTMC™ coated corrector plate and through the corrective optics to form a bright f/2 image across a 16 mm image circle. What this results in for you is an image of deep sky objects resolving on your smaller format camera in an incredibly short period of time. Sky-Watcher states that the exposure time you’ll need is so short in fact you may not need autoguiding with this scope! With a 250 mm focal ratio, this optical design gives you a wide take on the night sky; allowing you to quickly capture the breathtaking beauty of objects like the Pleiades and Orion Nebulae!

Compact Astrograph Build
The HAC optical design doesn’t just make the HAC125DX fast, it also makes it a compelling compact telescope option! At just 15.7″ in length, 6.3″ in diameter, and 8.4 lb. in weight, this scope is perfectly at home on some standout portable mounts like the Sky-Watcher EQ-AL55i Mount and Sky-Watcher Wave 100i Strainwave Mount. Focusing the quick and compact optics on your target is achieved via helical focus knob on the rear housing which holds the collimatable Mangin primary mirror. This allows your camera to stay static in the front corrector assembly, making cable management simple!
