WebA dark-current of 8 X 10^-5 pA is much smaller than 10 pA, which is the multiplied dark current level that just begins to significantly degrade the SNR at Ir = 10^-10 W/m^2. ... Almost by definition, amateurs are presently constrained to observations within our atmosphere. Notwithstanding the problems of infrared photodetector sensitivity ... Visual phototransduction is the sensory transduction process of the visual system by which light is detected to yield nerve impulses in the rod cells and cone cells in the retina of the eye in humans and other vertebrates. It relies on the visual cycle, a sequence of biochemical reactions in which a molecule of retinal bound to opsin undergoes photoisomerization, initiates a cascade that signals detection of the photon, and is indirectly restored to its photosensitive isomer for reuse. Phototr…
