ZWO 2"LRGB fiter set (SKU: ZWO LRGB2)

ZWO 2" LRGB Astrophotography Filter Set (SKU: ZWO LRGB2)

The ZWO 2" LRGB Astrophotography Filter Set is a meticulously engineered collection of four professional filters, perfect for enhancing the performance of monochrome cameras. These filters deliver exceptional results, achieving over 90% efficiency within their peak transmission bands. Crafted from high-quality Schott glass substrates and featuring a comprehensive multilayer coating, these filters ensure your astrophotographs are vivid and full of contrast.

What sets the ZWO LRGB 2 filters apart is the intentional separation of the maximum transmittance for the Green (G) and Red (R) filters. This precise selection effectively mitigates signal interference from sodium and mercury lamp spectral lines, common sources of light pollution in astrophotography.
