Well this is a nice little webcam that you can get pre modified at most astronomy suppliers to be used better in low light conditions
It costs around £90-100.00 for one of these although it gives a nice clear, crisp image it fails to live upto its expectations in the night time conditions of an investigation.
Once the light dims, not even gone out yet, the image loses its clarity and starts to judder after a while where the camera is trying to focus on something which it cant quite do
Great for normal useage...avoid for investigations though :(
