Quick Overview

  • Premium 1.25” LRGB filter set for use with monochrome astronomy cameras
  • Precision passbands partially block light pollution from sodium lamps while passing OIII emission from nebulae for a more natural image color
  • IR blocking from 700nm to 1100nm to eliminate need for a separate IR-cut filter >92% transmittance, polished to ¼-wave, and fully multicoated to ensure optimum images
  • Ideal for use in ZWO manual and electronic filter wheels

Product Details

The ZWO LRGB125 Filter Set includes four 1.25” mounted astrophotography filters that pass red, green, and blue bands of light as well the full luminance spectrum across the visible band. By taking individual images with each of these filters and a monochrome astronomy camera and combining the separate images with standard processing techniques, you can create beautiful correct-color images of planets and deep-sky objects.

This premium filter set is designed to approximately equalize the sensor response of the ASI1600 monochrome camera, and the RGB color combination is weighted to approximately 1:1:1 for accurate color rendering. The ZWO LRGB125 filter set is ideal for use in the ZWO EFW Mini or EFW8 electronic filter wheels with monochrome ZWO cameras.

The precision passbands of the LRGB filters include a gap between red and green to improve color balance and partially block the sodium line at 589nm to suppress light pollution from low and high pressure sodium lamps. The blue and green filter passbands overlap slightly to include emission from OIII to help achieve a more natural color when imaging nebulae. The ZWO LRGB filters also block infrared wavelengths from 700nm to 1100nm which means a separate IR-cut filter is not required. Each filter has a transmittance of at least 92% in band, and each is optically polished to ¼ wave to help you get superior images. All surfaces have multi-layer antireflection coatings for increased transmittance and elimination of ghost reflections.

This set is not suitable for imaging with DSLRs or one-shot color astronomy cameras because they include a Bayer array to achieve color images intrinsically.
