Optec - #58 Light Green, 50mm diam x 2mm thick
Like the #47B (Blue), this filter was used for early RGB imaging. The low transmission in the green and some IR leak makes it a poor choice now for color work. However, it is an inexpensive way to get the sharpest image from most telescope systems. Working at the visual wavelength peak, most telescopes including the popular SCTs and reducers will give their best performance with this filter.
The Optec IFW Intelligent filter wheel (#17350) is the ideal compliment for holding this filter
