WebBaader CMOS RGB Bandpass Filter Set, suitable from f/15 to f/1.8. Anti-reflection RGB filter (red/green/blue) with extremely high transmission of the respective color channel, thus simultaneously reducing stray light and reflections to an unprecedented level. Balanced RGB design allows subframes to be taken with the same exposure time ... WebThe cost of photometric filters currently represents a significant barrier to the realisation of a low-cost photometric system. Consequently, I decided to explore the construction of photometric filters using readily available planetary filters. Planetary filters are dye-in-glass coloured filters loosely based on Wratten filter prescriptions.
