Binorum Bahtinov Focusing Mask 80-100mm
Professional Astrophotography Focusing Solution
The **Bahtinov focusing mask** by Binorum is a unique tool designed for achieving perfect image focus in astrophotography. This precision-crafted plastic mask installs directly onto the telescope entrance, compatible with telescopes having an outer objective diameter from 80mm to 100mm.
How the Bahtinov Mask Works
The focusing process with your camera on telescope or lens follows these simple steps:
Step-by-Step Focusing Guide
- Attach the mask to your telescope and point the telescope toward a bright star
- Turn on your camera and observe the selected star on the live view screen
- If the image is still not in focus, the central line of the Bahtinov grid will appear offset
- Adjust the focuser until this central line sits precisely between the other two lines
- You have now achieved optimal focus - remove the mask from the optics and begin exposing your target object
Key Features and Benefits
- **Precise focusing accuracy** for superior astrophotography results
- Compatible with telescopes 80-100mm outer diameter
- Durable plastic construction for long-lasting performance
- Easy installation and removal
- Lightweight and portable design
- Essential tool for deep-sky imaging
Technical Specifications
- Telescope compatibility: 80-100mm outer objective diameter
- Material: High-quality plastic
- Installation: Front-mount on telescope entrance
- Weight: Lightweight for minimal impact on telescope balance

Why Choose a Bahtinov Mask?
The Bahtinov mask revolutionizes astrophotography focusing by creating distinctive diffraction spikes around bright stars. When perfectly focused, these spikes form a symmetric pattern that makes achieving **critical focus** incredibly precise and reliable. This tool eliminates guesswork and ensures your astrophotography sessions produce tack-sharp images every time.
Ideal Applications
- Deep-sky astrophotography
- Planetary imaging
- Long-exposure photography
- CCD and CMOS camera focusing
- Visual observation setup
- Telescope collimation verification
