CHROMA TECHNOLOGY LRGB FILTER SET CMOS The SharpStar flattener can be

The SharpStar flattener can be connected to the telescope by using the Zeiss standard thread (male M68x1) or a M63x1 female thread

in this way it is possible to use 4 optics

The bottom slide is a 4” dovetail bar 400mm length

Strong absorption can be seen spectroscopically at 5172Å

This test is rarely provided by any producer and it is a standard for high quality filters

CHROMA TECHNOLOGY LRGB FILTER SET CMOS The SharpStar flattener can beThe 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.
