This mounting kit allows for a flexible and compact setup and convenient use of ZWO ASIAIR Pro, Plus, Plus 256, or Mini and ZWO EAF on the ToupTek GS series telescopes with AR focuser and focal length of 150, 200, 250, 300, and 350mm. Note that the kit cannot be used with the AC focusers and with the GS-100 (100mm) model in the GS series.

The belt drive has a tension mechanism that supports a freewheel functionality on the focuser ring for easy manual adjustments. This allows for quick manual focusing in the desired direction. The 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 guide scope can be attached using the provided clamps either on the top or on one of the sides of the main frame. ASIAIR can be placed in various orientations and in different positions on both sides of the main frame.

See this page (the link is TBD) for assembly instructions and usage instructions. Please also use that page to learn how optional parts of the kit can be applied.

The mounting kit includes:

  • 3D-printed components
  • All screws and nuts required for assembly and operation
  • One pulley for the ZWO EAF (select the version you have below)
  • One timing belt
  • Optional accessories if selected

Optional accessories are also available for the kit. The accessory plate has its own page which explains its functionality. The kit can be purchased in red or red color, whereas the red color provides almost a perfect match to the colors of ZWO components and the telescope.

Please note that some pictures in the image gallery might 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.

Note: Photastro is gradually transitioning to a download-first model where all products will be available as digital downloads by default.
