This was later reduced to a 160x120 format by Glen Jolly who did 4x4 pixel binning. This is not unexpected if streaks in individual frames are at least 4 pixels long. It was then found that the main remaining source of noise was contributed by pixels at the edge of the 110 pixel wide circular fov of the telescope-camera system. This noise was eliminated by only analyzing a 64x64 sub-array within the 110 pixel wide circle. Using the 64x64 sub-arrays in combination with the streak detection program, all four very dim streaks stood out well above the background.
Work is now underway to improve processing efficiency.
