Rotate your camera with ease and compose your shots with one click. The ZWO CAA (Camera Angle Adjuster) is ZWO’s precision electronic camera rotator, designed to simplify composition with automated software control and accurate framing.

Key Features

• Compact & Lightweight – Only 16.5 mm thick and 465 g; replaces the standard 16.5 mm ZWO adapter.
• High Efficiency – Stepper motor drive provides smooth rotation with zero deformation through a full 360° turn.
• High Positioning Accuracy – 0.02°/step resolution; positioning accuracy better than 0.1°.
• High Rigidity & Load – Withstands > 15 cN·m torque to keep your imaging train rigid.*
• High Speed – Rotates up to 7.5°/s to reduce waiting time between compositions.
• Multi‑Compatibility – Works with ASIAIR, ASIStudio, ASCOM and supports manual button control (optional HC).
• Easy Cable Management – Single USB‑C provides both power and data.

*ZWO lab test example: ASI461 + 7×50 EFW + ~1 kg accessory load (overall ≥4 kg).

Specifications

Why ZWO CAA?

The CAA makes astrophotography composition easy and fun. Rotate to the exact angle without loosening adapters or risking tilt, and keep focus/backfocus unchanged while framing mosaics, nebulae and galaxies.

Compact & Lightweight

Despite its slimline 16.5 mm body and 465 g weight, the CAA offers exceptional rigidity and replaces the standard ZWO 16.5 mm adapter in many imaging trains.

High Accuracy

With 0.02° steps and <0.1° positioning accuracy, the CAA provides repeatable angles for multi‑panel mosaics and re‑framing across sessions.

Fast Rotation

Up to 7.5°/s rotation speed reduces downtime between targets and makes test framing quick.

Multi‑Compatibility

The CAA supports ASIAIR, ASIStudio, ASCOM and manual button operation (HC optional). It integrates neatly into the ZWO ecosystem and common imaging trains.

Easy Cable Management

A single USB‑C cable handles both power and control, reducing clutter and snags.

Product Details

• Type‑C port – Power and data in one connection.
• HC port – For optional hand controller.
• Locking slot – Insert a hex wrench to lock rotation to remove jammed adapters.

Connections & Backfocus

1. With ZWO FF series refractors (with/without reducer), use the supplied M48 adapters and replace the 16.5 mm adapter with the CAA.
2. For Duo or 2600AIR cameras requiring M54, an optional adapter is available.
3. Standard 55 mm backfocus spacing examples shown below.

Installation Steps

1. Install the CAA on the threaded drawer/tube adapters.
2. Install the optional 21 mm M54 adapter to keep the correct focusing distance (if required).
3. Install your camera. For M48 cameras, convert the CAA rear from M54 to M48 using the supplied plate.

Why Imagers Love It

Adjusting camera rotation mid‑session often means loosening adapters, risking tilt or changing backfocus. The CAA removes that friction: secure, controlled rotation that keeps your imaging train rigid and aligned. Perfect for deep‑sky mosaics, lunar/solar panels, portable rigs and mono + filter wheel setups.
