Product Details
✓【Wide Telescope Fit】Focusing fishbone plate fits telescope outer diameters from 104 to 146mm. Compatible with Dobsonian Mak Cas and telescopes for flexible use across setups.
✓【Precise Star Focus】Telescope focusing mask creates 3 pairs of diffraction spikes to help find focus faster. Reduces guesswork during astrophotography and supports clearer star image alignment.
✓【Astrophotography Use】Designed for stargazers using telescopes in night sky observation and imaging. Helpful when adjusting focus under changing visual conditions to capture clearer star details.
✓【Stable Centering】Three metal posts clamp the mask in position to help prevent shifting during use. Supports centered placement on the telescope for more consistent focusing results.
✓【Aluminum Alloy Build】Made of aluminum alloy with a 1mm thickness for a lightweight structure. Adds minimal load to the telescope while remaining practical for repeated observation sessions.
