Buy it if
- You shoot mosaics or return to targets and want the same framing every time.
- You control your rig from an ASIAIR, ASIStudio or ASCOM software such as NINA.
- Your imaging train uses M54 or M48 threads with room for 16.5 mm.
Skip it if
- You frame once and leave the camera alone: many refractors, like my Askar SQA60 Pro, already have a manual 360 degree rotator.
- Your train is tight on space around the adapters: it can foul an adapter plate.
- You want a hand controller included: it is sold separately.
The ZWO CAA is a 16.5 mm motorised camera rotator that turns the camera in 0.02 degree steps, and it has sat in my imaging train behind the C11 EdgeHD, the Askar SQA106 and the ZWO FF110.

1:25 First impressions, building the rig
1:25 So, I'm just going to explain a little bit more about what else I'm using with the mount just here. 1:29 So, of course, we have the Celestron 11-in Edge HD telescope.
1:30 The full back-end, C11 Edge HD + reducer + filter wheel + 2600MM Air
1:30 It is a beast. 1:33 But, down the back end over here, I'm going to spin it around. 1:35 Connected to the telescope, we have a 0.7 times reducer as well as a T-adapter, camera angle adjuster from ZWO as well, as well as a 7 by 2-in filter wheel, and then the ASI 2600 monochrome air camera.

Should you buy it?
72/100 Stars for Your Buck
Pros
- Motorised rotation in 0.02 degree steps, positioned to better than 0.1 degree, so framing is repeatable.
- At 16.5 mm it takes the place of the standard 16.5 mm adapter on ZWO's FF refractors.
- One Type-C cable carries power and control.
- ASIAIR, ASIStudio and ASCOM control, so NINA can turn the camera too.
- It has sat in my imaging train behind the C11 EdgeHD, the SQA106 and the FF110.
Cons
- It can clash with the adapters around it: on my SQA106 it needed a 10 mm spacer to connect.
- At £399 it costs twice as much as ZWO's own EAF.
- The hand controller is sold separately.
- It adds 465 g to the back of the imaging train.
The CAA earned its place in my imaging train, but check the adapters around it: on my SQA106 it kept colliding with an adapter plate until I added a 10 mm spacer.

- Is the ZWO CAA motorised? Yes. A stepper motor turns the camera in 0.02 degree steps at up to 7.5 degrees a second, controlled from the ASIAIR, ASIStudio or any ASCOM program; a hand controller is an optional extra. The specifications ↓
- Will the ZWO CAA fit my imaging train? It has an M54 female thread at the front and M54 or M48 male at the back, with a 48 mm clear aperture, and it is 16.5 mm thick. On my Askar SQA106 it kept colliding with a surrounding adapter plate, and a 10 mm spacer fixed it. Watch it in my videos ↓
- Where have you used it? Behind the 0.7x reducer on my Celestron C11 EdgeHD with a 7 x 2 inch filter wheel and the ASI2600MM Air, behind the Askar SQA106, and on the ZWO FF110. In use ↓
- How much does the ZWO CAA cost? The prices I recorded: £399 at First Light Optics (UK), in stock; $399 at Agena Astro (US), in stock; $399 at ZWO store (Global), in stock. A record, not a live price The verdict, the readers and the sellers ↓
- What have I not tested on the CAA? I have not measured the CAA's positioning accuracy or timed a full turn myself.
