Filter allows one to dial in the filtering of various wavelengths of light.
Works beautifully on nebulae and enhances planetary views. Purchased directly from Al Misiuk at NEAF 2002. (Filter wheel was hand picked from several to assure buttery-smooth rotation.)
Comes with the transmission sheet data (three peaks), and the dial is calibrated
