Mounting kit for ZWO ASIAIR Pro, Plus or Mini and EAF with belt drive for RedCat 51

This mounting kit allows flexible and compact setup and convenient use of ZWO ASIAIR Pro, Plus or Mini and ZWO EAF on RedCat 51 telescopes from William Optics.

Compared to other solutions, this kit does not require changing the mounting of the RedCat 51 to the dovetail rail. The belt drive has a tensioning mechanism that supports freewheeling of the focus drive. This allows quick focusing in the desired direction. A belt drive is based on widely used pulleys and belts. This makes it easy to find a replacement or vary the dimensions or gear ratio.

A guiding telescope can be attached to the top with flexible clamps. These clamps are designed to allow attachment of different dovetail rails. Unfortunately, their size is not standardized...

A similar attachment kit is also available for the CAT Saddle Handle Bar offered by William Optics

The mounting kit also includes two eyelets for cable management.

See this page for more details, and this page for assembly instructions and usage tips.

Included in the mounting kit are:

  • 3D-printed components
  • All necessary screws and nuts
  • One pulley for ZWO EAF
  • One timing belt
  • ~30cm hook-and-loop fastener for cable management (also known as "velcro" (R)).

Please note that some pictures in the image gallery show additional equipment and components, such as ASIAIR and EAF, lenses or telescopes, etc. All these parts can be used with this product but are not included in this product. Please refer to the list above to see which parts will be included with your order.
