Hi
What is your target object?
If your are planning meteor observation, then
I guess, Mintron MTV-72S85HP-ex-nf may not have enough sensitivity.
From the web pages, its sensitivity is
>Typical: 0.01 Lux @ F1.2, 5600K, 30IRE
>Star light mode : 0.0001 to 0.00005 Lux @ F0.8, 5600K, 10IRE
0.01lux is not enough for meteor detection, it will capture a few meteors in a month.
0.0001 lux is enough, but I guess it uses frame stacking mode, that cannot be used in motion detection.
1/50 or 1/60 shutter time must be used for UFOCapture meteor detection.
Slow shutter or frame stacking does not make movie but a still picture.
As far as I know, there is no low cost CCIR color camera that have enough sensitivity.
Monocrome Watec WAT-902H2Ultimate or WAT-902H3Ultimate is my recommendation for PAL or NTSC. |
