Sunt 2 filtre de luminanta uzuale, L si C. L este UV/IR cut, C este clear. Poate cu un reflector se poate folosi C, pe o luneta focusul e sigur aiurea. " If the stacked transmission curves of RGB yielded the transmission curve of L, then the amount of sky noise would be identical in both the RGB and the L. Differences occur because the combined transmission of RGB is a bit less than that of L [...]".
