Optec Hercules Focusing Rotator

Starting Price: $2,495.00
Price as Configured: $2,495.00
Brand: Optec / SKU: OP-19749

Optec’s new Hercules rotating focuser brings together precision focusing and camera field rotation in one compact, ultra-rigid package. Designed as a slightly smaller sibling to the proven Gemini focuser/rotator, Hercules delivers a full 3-inch clear aperture with 0.35 inches (9mm) of linear travel, all while maintaining an incredibly slim profile at under 2 inches thick.

Powered by Optec’s best-in-class ASCOM and Alpaca drivers, Hercules offers far more than just focus control. Advanced features include alt-az field de-rotation, image orientation, composition framing, and guide-star acquisition—making Hercules a versatile tool for both astrophotography and scientific imaging.

Compact, precise, and engineered for performance, Hercules puts big-league functionality into a slimmer, lighter package.
