Four multi-coated interference filters. Optimized for imaging with monochrome CMOS and CCD cameras. It consists of:

• 36 mm interference filter red, green, blue
• 36 mm UV/IR block filter

This filter set is an interesting alternative to the significantly more expensive filter sets from other manufacturers on the one and to simple colored glass filters on the other hand. Compared with the latter, the ZWO filters offer a brighter and more contrasty image.
