Description

ZWO 36mm Unmounted Narrowband Filter Set - Advanced HSO 7nm Filters for Astrophotography

Enhance your astrophotography with the ZWO 36mm Narrowband Filter Set, expertly crafted for capturing stunning images in the HSO color palette. Designed to meet the needs of professional astrophotographers, these filters excel in high transmission and precision.

This set includes three high-performance filters, each with a 7 nm half-bandwidth, ensuring exceptional contrast and clarity. Constructed from 2 mm thick optical glass and featuring a comprehensive multilayer coating, they are optimized for the best possible performance.

These narrowband filters are ideal for enhancing contrast and capturing vivid color photography of nebulae types—including emission, planetary, and supernova remnants—even in areas with significant light pollution. Note that the Hα and SII filters require the purple-coated side to face your camera for optimal results.
