Don Goldman Tru-Balance LRGB E-series Color Filters set of 4, 50 mm unmounted.

These filters are designed to simplify your imaging efforts, with shorter imaging time, G2V white-point balance , balanced OIII nebula color, and ~1:1:1 RGB combining for Kodak -E CCDs. They are an outgrowth of over a year and a half of research. Also works with the Apogee AP47 and Finger Lakes Dream Machine (MIG1024). All of the filters come in black anodized screw-in holders that fit most filter wheels. All LRGB filters have >90% peak throughput with AR (anti-reflective) coating.

Special-order filters required for use with Finger Lakes Instruments filter wheels. (No extra charge.) If you're planning to use this with an FLI system, please specify the model when placing your order.
