NGF2 Focusser, Novak Spider, and 7x50 Celestron Finder. The Filter
Wheel has Dicroic Munsell Filters from the SpectroPhotometer of a Hell
DC350 Scanner (circa 1982). These filters are designed to duplicate
the Color Responsivity of the Human Retina, and bandpass exactly at that
responsivity curvature.
