LRGB is the classic recipe for true-color astrophotography with a monochrome camera—and ToupTek’s LRGB set is built to make that workflow cleaner, sharper, and more contrasty under real-world skies. The Luminance filter captures the fine detail, the RGB filters capture color, and the coatings are designed to transmit the good stuff while knocking down urban light pollution and keeping halos to a minimum. The result: better contrast, more natural color, and star shapes that stay well-behaved.
Purpose-built LRGB set for monochrome astronomy cameras (professional-grade color workflow)
Helps produce authentic color balance and stronger contrast—especially under light pollution
High transmission (>95%) to keep exposure efficiency strong
Extremely low halo effect for cleaner stars and better fidelity
Quartz glass substrates with double-sided high-precision polishing for optical consistency
Advanced coating stack using IAD (Ion Assisted Deposition) for durable, precise band edges
OD ≥ 5.0 blocking for strong suppression outside the passbands
Available in multiple formats so you can match your camera/filter wheel: 36mm unmounted, 1.25", or 2"
