Optolong LRGB + SHO 7nm Filter Set - 2" Mounted

Optolong LRGB + SHO 2" Imaging Mounted 7 Filter Set is a midrange LRGB/RGB filter set (2").

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.
