The filter set consists of four multi-coated interference filters. It is optimized for astrophotography with monochrome CCD and CMOS cameras. The filter set consists of:

• 2" interference filter red, green, blue (RGB)
• 2" UV/IR block filter

The filter set is a good alternative to the usually much more expensive filter sets of other manufacturers and a much better alternative to simple color filters. The transmission of these ZWO filters is considerably higher and the result is a high-contrast image which is very well suited for further processing.
