The Optec Hercules Focusing Rotator combines camera field rotation with precise telescope focus in a sleek package. Offering a full 3-inch aperture, 0.35" travel, and various configurations including Takahashi Epsilon kits, it maintains a low profile with advanced ASCOM and Alpaca driver capabilities for sophisticated imaging needs.

Optec has introduced the Hercules Rotating Focuser, a new device that merges camera field rotation with telescope focusing capabilities. More compact than its predecessor, the robust Gemini Focusing Rotator, the Hercules offers a full 3-inch clear aperture and 0.35 inches.
