is cherenkov radiation even observable during dawn/dusk +/- 2 hours? I imagine that the atmospheric refraction of the sun would seriously hamper those observations during that time period.

On traditional telescope using photomultipliers such as Magic, Hess or Veritas: no. But systems with solid state detectors such as FACT are moving in that direction.

Can you explain that for me? I'm not sure how better detectors let you delete the noise from the sun.
