Precise focusing made easy – now also ideal for use with HyperStar systems.

The new two-piece Bahtinov mask has been specially designed for the Celestron 9" Schmidt-Cassegrain and offers significant advantages over conventional one-piece Bahtinov masks.

Thanks to its two-piece design, the mask can be easily attached to the telescope from the front – even if a HyperStar system with a camera and cables is already installed. The two halves of the mask connect precisely and securely via integrated magnetic connectors.

This means that, particularly when space is tight around HyperStar cameras, there is no need for the fiddly process of fitting a large, one-piece mask over cables and attachments.

Key benefits:

• Specially designed for the Celestron 9" Schmidt-Cassegrain (C9)
• Two-part design for easy assembly
• Integrated magnetic connection for a precise fit
• Ideal for HyperStar systems
• No need for fiddly rethreading over cables or the camera
• Fast and precise focusing
• Robust, high-quality 3D-printed components

The mask produces the familiar, precise Bahtinov diffraction pattern for accurate focus determination in astrophotography and is ideal for deep-sky, planetary and EAA applications.
