Square Filter System

The Skylabs Square Filter System is a professional-grade solution engineered specifically for the precision and versatility required in astrophotography and outperforms regular daytime photography needs. By moving beyond traditional circular filters, this system provides a more efficient, cost-effective, and technically superior way to capture your images.
 
Key Features
Universal Compatibility & Cost Savings: The 100mm square format is a "one-size-fits-all" solution. You can use the same high-quality filters across all your lenses, regardless of their thread size, saving you the expense of buying duplicate filters for different glass. Equipped with 9 adapter rings: 49/52/58/62/67/72/77/82/95 mm. Individual adapter rings can also be purchased separately.
Magnetic Quick-Change Mount: Avoid the frustration of fumbling with threads in the dark. Our filters are held securely by magnets, allowing for near-instant swaps or removals. This magnetic connection ensures you don't accidentally shift your focus or bump your alignment during a session.
Ultra-Wide Performance: Designed with an ultra-slim frame and a large diameter, this system is built to prevent vignetting (corner darkening), even with ultra-wide-angle lenses.
Enhanced Protection: The integrated filter frame acts as a protective shield against accidental drops and scratches. It also keeps your optics clean by preventing fingerprints and blocking parasitic reflections from nearby light sources that can ruin long exposures. The kit comes with 3 filter frames. Individual frames can also be purchased separately. 
Standardized Fit: Fully compatible with standard 100x100 square filters, making it the perfect home for our Enhanced Bahtinov Mask and other essential astro-tools.
