Hi Bill,
The longest focal length lenses in the NEMETODE network (12mm) can achieve reference star O-Cs of 0.5 arcmin, very similar to the CAMS and SonotaCo networks. HD video systems should surpass this, but they need beefy PCs to cope with the data bandwidth and data processing requirements.
Both SD and HD video systems have their uses in estimating meteor rates, radiants and solar system orbits. Let’s see what your DSLRs can do this summer.
Cheers,
Alex.
