How to install a lens and ZWO camera on a mount

The first step is to securely install your camera along with your lens on a star tracker or mount. Here's how to get started:

Lens with a Foot

If your lens comes equipped with a foot, the process is straightforward. Simply attach the foot to your star tracker 1/4" mounting screw, or attach a dovetail plate to the foot if your mount features a Vixen or Losmandy style dovetail. This dovetail can then be easily mounted onto your star tracker or telescope mount, ensuring a stable and secure connection.

Lens without a Foot

For lenses that do not have a foot, you will need to use the ZWO holder ring.

There are three holder rings available, select the one that matches the diameter of the outer body of your cooled ZWO camera:

Attach the holder ring to your star tracker using a 1/4" screw. If you are using a mount with a Vixen or Losmandy style saddle, you will need to attach a dovetail plate to the bottom of the ring to interface with the mount.
