Unlock the full potential of your Sky-Watcher Skymax 180: Surgical focus and real-time collimation.
High-Resolution Focusing & Collimation Tool
The Skymax 180mm is a planetary powerhouse. However, with a massive 2700mm focal length, achieving perfect focus requires surgical precision. Our custom Tri-Bahtinov mask is the essential tool to lock in your focus and verify your collimation in seconds.
🎯 Dual DiagnosticManage your focus and check mirror alignment simultaneously. Perfect for SharpCap, FireCapture, or ASIAIR users. |
🛡️ Premium Cap-Style FitUnlike universal masks, ours fits perfectly over the tube. Includes pre-installed felt lining for a scratch-free experience. |
The Tri-Bahtinov design generates three distinct sets of diffraction spikes. By ensuring these spikes cross exactly at the center, you guarantee that your secondary mirror is perfectly aligned and your focal plane is precisely set.
Made from high-quality Premium PETG, this mask is built to withstand thermal shifts and high humidity without losing its shape or precision.
💡 Expert Insight: "The Skymax 180 is a rock of stability; once it reaches thermal equilibrium, it stays perfectly set. However, at 2700mm, the critical focus zone is incredibly narrow. Use the mask on a magnitude 2 or 3 star near your planetary target to lock in sub-pixel focus. It’s the only way to ensure you’re utilizing the full 180mm aperture without letting atmospheric seeing trick your eyes on screen."
