(meteorobs) video capture system compared to straight video

[Larry]

I do not have the newest system which uses a video card. I have a Sentinel 
3. The centroid has a higher gain than the entire image causing a poorer 
rendition of background reference stars. I believe that is the reason for 
that particular change, to bring out stars needed for image calibration that 
are located outside the centroid.
