The SharpStar field flattener & reducer for the 140PH is a 3" dedicated corrector with a reducing power of 0

Strong absorption can be seen spectroscopically at 5172Å

CHROMA TECHNOLOGY LRGB FILTER SET CMOS in this way it isThe Chroma LRGB filter set is designed for deep space imaging applications with monochrome CMOS CCD sensors. All transmission and blocking (OD) data are actual, measured spectra of representative production lots. Spectra varies slightly from lot to lot. Optical density values in excess of 6 may appear noisy because such evaluations push the resolution limit of low light level measurements.
