Optolong LRGB + SHO 7nm Filter Set - 36mm Unmounted

Optolong LRGB + SHO 7nm (7 pieces) - 36mm Unmounted is a midrange LRGB/RGB filter set (36mm).

Best for building natural-color broadband data with a monochrome camera.

Choose filter size around the sensor diagonal, telescope speed, and filter-wheel or drawer geometry. Flats are still required; a filter can improve contrast, but it will not rescue tilt, bad focus, or poor calibration.
