[Laser] Frame capture from F1AVY video with integration to improve SNR

[laser]

I never tried posting a photo to this forum so I don't know if that's
possible but here goes:

Top is a single frame grab from the F1AVY video.

Bottom is all 87 frames integrated and averaged using AstroVideo a program
used to pull star images up out of the noise when captured with CCD cameras.

Just in case it can't be viewed here I also posted it here:
