ZWO Filter-Set L-RGB 36mm Unmounted

This filter set is an inexpensive alternative to the usually much more expensive sets from other manufacturers. Despite the low price, they are multi-coated interference filters.

The set is optimized for use with the ASI cameras from ZW Optical. Combining exposures using the three colour filters and the luminance (IR cutting) filter, lets you generate colour images on a computer. Unlike with a colour camera, the full resolution of your camera chip with each colour is used with to this method – just like the pros!
