Broadband four-band light pollution filter For nebulae AND galaxies/clusters Compatible with DSLR, CMOS, and CCD cameras Transmission rate greater than 93% on the H-Alpha, O-III, H-Beta, S-II, and N-II lines

The C0, CG, and C1 series cameras with global shutter CMOS sensors were designed to be small, lightweight imagers for Moon and planets and for automatic telescope guiding. With proper image calibration, these cameras provide surprisingly good results also in entry-level deep-sky imaging. The used CMOS sensors response to light is linear up to very close...
