Fine optically polished glass; Multi-layer anti-reflection coating
Use
Camera use
Mono astronomy cameras
Best for
Broadband galaxies, reflection nebulae, star clusters, and natural-color imaging
Astrophotography Fit
Best for building natural-color broadband data with a monochrome camera.
ZWO LRGB 36mm Filter Set is a budget-friendly LRGB filter set (36 mm). Passbands: Luminance visible band with 700-1100 nm IR cut / Red red visual band / Green green visual band / Blue blue visual band.
Best for building natural-color broadband data with a monochrome camera.
Choose filter size around the sensor diagonal, telescope speed, and filter-wheel or drawer geometry. Flats are still required; a filter can improve contrast, but it will not rescue tilt, bad focus, or poor calibration.
Best paired with
Monochrome cooled cameras and electronic filter wheels
Broadband galaxies, clusters, reflection nebulae, and star fields
Dark-sky sites or well-calibrated light-polluted workflows
Not recommended for
One-shot color cameras where LRGB adds complexity without benefit
Heavy light pollution without enough total integration
Emission-only projects where narrowband filters are the priority
