ZWO LRGB filter set 2 inch

ZWO LRGB filter set 2 inch is specially tailored to monochrome astro cameras and offers four high-quality interference filters: Red, Green, Blue and UV/IR block. Thanks to the 2-inch size, you maximize light output and reduce exposure times, while the anti-reflective multilayer coating as well as the IR block produce sharp, natural colors.

Key benefits
✓ Four high-quality interference filters (R, G, B, L) for true color fidelity
✓ UV/IR-block L-filter prevents blur caused by unwanted IR light
✓ Multi-coated anti-reflective layers for minimal reflections and ghosting
✓ Fine optical polished glass for maximum clarity and contrast
✓ Hole in sodium D-lines prevents light pollution from street lights
✓ 2-inch format for short exposure times and full-frame compatibility

Practical application
Use this set with a ZWO ASI mono camera and a 2-inch filter wheel (10 mm filter spacing to sensor) for LRGB deep-sky or planetary photography. The filters are parfocal, so you don't have to refocus when switching between channels.
