상품 특징

• PRECISION STAR FOCUSING — Engineered slit pattern generates a clear three-spike diffraction image in your eyepiece or camera live view, letting you dial in critical focus on any bright star in seconds rather than guessing by eye
• CUSTOM FIT FOR 130 EDT REFRACTOR — Designed to slip snugly over the dew shield opening with a firm friction fit that holds securely during focusing sessions yet removes easily when you are ready to begin your imaging run
• DURABLE ALL-WEATHER CONSTRUCTION — Built from rigid, impact-resistant ABS that withstands cold observatory nights, damp conditions, and repeated field use without warping, cracking, or losing its precise slit geometry over time
• ASTROPHOTOGRAPHY ESSENTIAL — Eliminates the frustration of soft frames by giving you a definitive visual indicator of perfect focus before you commit to long-exposure deep sky, lunar, or planetary imaging sessions
• SIMPLE SLIP-ON DESIGN — No tools, adapters, or modifications needed to mount or remove the mask from your telescope tube, so you spend less time fiddling with gear and more time capturing photons under dark skies
