A common camera(non-low light) and a hemispherical mirror appears to be well
suited for daylight fireballs for a number of reasons.
a) Far less reflection artifacts than a all-sky lens camera.
b) Better definition & contrast of Sun against the sky.
c) Minimal field light saturation even with fixed focus & iris lens.
c) Reasonable sensitivity to minor light events.
This photo is with the mirror not yet fully aligned and height not adjusted
for maximum field. Still being worked on at this time with heating still to
do.
Red indicators are the few artifacts under strong morning sunlight.
BLUE circle is around a momentary sky ("Blip") event which is NOT ASSOCIATED
with the nearby sunlight spike in photograph. This was confirmed by an image
before & after the time of that event. I cannot estimate the magnitude with
my limited skills of observation.

Looks like basic setup will work for Daylight Fireballs without sun
shielding!
