According to Ken Oehler, the light sources to use are those "slim jim" lamps.
They're clear glass and have a single, long, axial filament.  Put the filament
directly above the sky screen.  The charm of this approach is that it's
actually more precise than using the sky as a light source since the filament
is so thin.

A double amen to this advice.  I would also try putting a large flow-rate fan on
your down-range target house's roof to keep the tunnel clear.  The tunnel
will tend to get very smokey if you fire at any reasonable pace.  I would also
use some sort of reduced-diameter port to fire through to try to get the smoke
to stay on the down-range side.  One thing that helps is to make this port by
spacing half a dozen plywood washers a few inches apart in the tunnel.  The
washers could be 12" OD to fit the tunnel and have a 4" X 8" vertical slot
in them.  The washers act as a sort of crude muffler for the tightly-confined
muzzle blast.  You will definitely need good ventilation in the basement:
plenty of gas will still escape into the room in spite of the above precautions.
