About
The standard-window member of Astronomik's three luminance filters, blocking ultraviolet and infrared while passing the visible spectrum for maximum signal in the L channel. Suited to most optical systems running a corrector or flattener, where the wider L-1 would show the system's residual colour error. 2" M48 mount.
