ZWO LRGB Filter Set
Best unmounted filter set for serious deep-sky astrophotographers.
Elevate your astrophotography with this high-performance LRGB filter set. Designed for superior color separation and transmission, these filters effectively minimize light pollution and block unwanted infrared wavelengths, resulting in clearer, more detailed celestial images. Featuring multi-layer anti-reflection coatings and precision optical polishing, they achieve over 92% transmission at the passband. This set includes four unmounted 36mm diameter, 2mm thick filters (L, R, G, B), ideal for seamless integration into standard filter wheels accepting this size, offering a durable and effective solution for capturing stunning views of the cosmos.

Know before you buy
These are unmounted filters. They are designed to be installed directly into a compatible electronic filter wheel.
These filters are compatible with any filter wheel designed to accept 36mm unmounted round filters. Please verify your filter wheel's specifications to ensure it supports this specific diameter.
No, you do not need an additional filter. Each of the L, R, G, and B filters in this set is already designed with an integrated IR cut-off to ensure sharp, clear imaging.
Yes, these filters are manufactured to be parfocal, meaning they have a consistent 2mm thickness. This minimizes the need for refocusing when switching between different color channels during your imaging session.
While they are optimized for ZWO astronomical cameras, they can be used with any camera that accepts 36mm unmounted filters. Their high light transmission is designed to complement the spectral sensitivity of modern CMOS sensors.
