Parfocal LRGB Filters

Broadband filters are parfocal which ensures that you will not have to refocus when you quickly switch filters to capture images.

Anti-Reflection Coatings

Multi-layers anti-reflection coating ensure no halos, ghosting or reflections. Filters are resistant to scratches and do not get affected by temperature change.

Equal weight on RGB filters

RGB color combine weights are 1:1:1

Limit Sodium Light Polution

A gap between green and red filters blocks out the primary Sodium light pollution line at 589nm and improves color balance and separation.
