Tri-Bahtinov Mask — Takahashi Mewlon 210

Precision Micrometric Focusing & Real-Time 3-Axis Secondary Mirror Collimation

The Takahashi Mewlon 210 is an exceptional Dall-Kirkham optical instrument (f/11.5), legendary for its pin-sharp planetary and lunar contrast. However, high-resolution imaging leaves no room for error: an approximate focus or a slight optical misalignment will instantly compromise your image quality and fine details.

🔭 The Tri-Bahtinov Advantage: Upgrade your Setup Routine

🎯 Live 3-Axis Collimation

While a classic Bahtinov mask only tells you when focus is reached, the segmented geometry of the Tri-Bahtinov goes much deeper. Perfectly aligned with the three secondary mirror adjustment screws, it allows you to analyze and tweak collimation in real-time directly on bright star diffraction spikes.

⚡ Alignment Under 2 Minutes

The open-tube layout of the Mewlon makes the secondary housing sensitive to thermal changes and transit vibrations. Checking collimation each session is vital. When the three central spike patterns cross perfectly, your Mewlon 210 is simultaneously focused and aligned.

Bespoke Fit Built to Match Takahashi Standards

Every single unit is tailored to match the precise outer diameter of the front cell of the Mewlon 210, providing optimal shielding and safety:

  • Flawless External Slip-On Fit: No marring thumb screws, no unstable clips. The mask slides smoothly over the front rim. Strict tolerances ensure it stays perfectly coaxial with the optical axis, even when tracking near the zenith.
  • Soft Felt Scratch-Guard Liner: The famous Takahashi paint finish deserves premium care. A high-grade continuous felt strip is hand-lined inside the inner rim. It dampens structural friction, completely avoiding scratches while offering a snug, reliable friction grip.
  • Rugged Black PETG Matrix: Forget low-grade PLA elements that warp under summer car storage heat. Our premium PETG structure is selected to withstand tough night conditions (heavy dew, deep frost). Its 100% opaque black colorway stops scattering to deliver high-contrast spikes.

"The Mewlon 210 packs amazing Japanese optical performance, but minor thermal secondary shifts can alter planetary contrast. The Tri-Bahtinov turns tedious Airy disk analysis into a simple, highly visual geometric alignment task. It is the definitive accessory to unlock 100% of your optical capability right from the start of the night."
