The Sky-Watcher HAC125DX is a compact, high-speed astrograph utilizing the Honders Advanced Catadioptric optical design that combines hybrid refractive and reflective surfaces to deliver sharp, ultra-fast wide-field imaging in a lightweight package. Featuring a lightning-fast f/2 focal ratio, it allows you to capture images 5x faster than a standard f/4.9 optic. Designed for wide-field astrophotography with lightweight equatorial mounts, this ultra-portable setup is ideal for anyone seeking an ultra-fast, ultra-compact imaging rig. The optical design utilizes a Mangin mirror with carefully engineered refractive components and a front camera placement that forgoes light-path folding, delivering an incredibly fast f/2 focal ratio with superbly sharp images across the field.
