QHY MiniCam8M LRGB & 7nm SHO Deep Sky Combo - 040056

This set of seven filters are made expressly for the QHY MiniCam 8M built-in filter wheel, which accepts specialized 19*12*1.1mm filters.  The set includes LRGB (Luminance, Red, Green & Blue) filters and 7nm SHO (SII, H-Alpha & Oxygen III) filters.

The filters have an optical density (OD)* of 5.

*Optical Density (OD): It works as a physical measure of the degree of light attenuation after passing through an optical filter, directly affects the filter’s ability to suppress unwanted light during imaging. A higher OD value indicates stronger suppression of stray light, effectively blocking most unnecessary light sources and thereby enhancing image contrast and detail clarity. 

Each filter set comes with a filter disc and a pair of tweezers.
