Universal On-OTA Mounting Kit for ZWO

The Universal On-OTA mounting kit for ZWO from Photoastro in Germany offers a set of mounting components for astrophotography setups using lenses and telescopes with a focus ring and is designed for use with the ZWO ASIAIR Pro or Plus and ZWO EAF. The kit helps in mounting essential hardware components for astrophotography and provides for compact, flexible mounting and allows using a range of lenses and telescopes in the same installation.

Universal On-OTA Mounting Kit for ZWOWith the Universal On-OTA mounting kit for ZWO, the ZWO ASIAIR astrophotography computer, the ZWO EAF, and the guide scope are placed on hexagon rings embracing the OTA or a lens. This allows a compact and well-arranged setup. The same kit can be used with various OTAs and lenses.

This kit also adds a belt drive for the ZWO EAF. As the Photoastro team notes, “Compared to other mounting kits for ZWO EAF, this kit is based on a belt drive. The belt drive includes a tension mechanism supporting the freewheeling of the drive. This allows quick focusing in a needed direction. A belt drive is based on pulleys and timing belts with standard sizes and profiles. With this, you can easily find a replacement or variate dimensions or the transmission ratio.”

The top plate contains mounting for a guide scope with a dovetail-shaped base. The provided clamps allow the mounting of a large range dovetail-shaped bases.

Both the ZWO ASIAIR and ZWO EAF are mounted on sliding holders so that they can be used in different positions supporting a large range of mounting variations. All rails of the kit have eyelets at the ends for cable management. All current versions of the ZWO ASIAIR can be mounted. The Plus and Pro versions have the same mounting dimensions and the Mini has different mounting dimensions and requires a dedicated mounting plate.

The kit can be ordered with an additional Vixen-style dovetail plate, a Losmandy dovetail plate or with a Universal Bottom plate which can be used with other dovetail plates for attaching the setup to a mount.
