ZWO LRGB Filter

This set is specifically engineered to maintain a 1:1:1 color weight ratio, which simplifies your post-processing workflow by ensuring balanced color reproduction right from the start. The high light transmission of over 92% also means you spend less time exposing, which is crucial for deep-sky imaging.

Yes, the luminance filter included in this set features a built-in UV-IR cut function. It effectively blocks infrared wavelengths between 700-1100nm, which helps reduce star bloating and improves overall contrast in your images.

These are standard 1.25-inch threaded filters designed to fit most filter wheels and standard eyepieces. However, if you are using a full-frame sensor, you may experience vignetting, so these are best suited for cameras with smaller sensor formats.

Wavefront accuracy refers to the flatness and optical quality of the glass surface. A 1/4 wavefront rating ensures that the light passing through the filter remains undistorted, which is essential for maintaining sharp, high-resolution details in your deep-sky captures.

While these are primarily color balancing filters rather than dedicated light pollution filters, the IR-cut feature helps minimize the impact of stray infrared light. This can result in cleaner images, but you may still need a dedicated narrowband filter if you are shooting from a heavily light-polluted location.
