Astroasis Camera Angle Adjuster (CAA)

The Astroasis CAA gives astrophotographers full 360° rotational control for perfect image framing. With degree markings, smooth damping and a secure multi-point locking system, the CAA maintains the correct focal plane while allowing precise angle adjustment.

Key Features

• 360° rotation for accurate framing and composition
• Degree markers for repeatable positioning
• Three locking screws keep the focal plane perfectly aligned
• Parts remain secure — even fully loosened screws cannot cause separation
• Compatible with 21mm M42–M42 extenders
• Standard M42x0.75 male and M42x0.75 female threads
• Damping resistance for smooth rotational feel

How It Works

The CAA sits between your telescope and camera, letting you rotate the camera freely without disturbing spacers, backfocus or optical alignment. Once the desired angle is set, the three locking screws secure the position without shifting the focal plane.

The adjuster integrates seamlessly with M42 imaging trains, including filter wheels, OAGs, flatteners, focal reducers and cameras using the M42x0.75 standard.
