Hi Sirko:
Sandia tested a Watec 902HS camera in an all-sky mode and found that
background stars were lost in the high noise level of this camera. You
indicate that the 902H has a limiting magnitude of 'zero'. Is this for
meteors or background stars?
I bought a Canon L2 Hi8 video camcorder which should arrive in the next
few days. I will use it with a 25 mm 2nd generation image intensifier. I
haven't tested the intensifier yet but I believe it is surplus 'new' so it
should have higher sensitivity than my experimental Stano intensifier. At
least I hope so. I will be doing spectroscopy with this system. Will the
'zero order' meteor images that are often recorded provide useful data for
your AKM video network? Zero order images are recorded much more often than
1st order spectra.
