Now that IS one cool little coil, congrats!
Ideal size for travelling ;-)

The EXIF info gave ISO 320 and 1/30sec - you could try stopping down ISO
to 50 and decreasing shutter down to 1/8 or slower and run the TC in very
low light, this should make streamers appear bushier on the pic. And, to
get the coil visible too, fire the flash at lowest power. Chances are that
your digicamera's automatic "Night Scene" mode does all this, without all
those manual adjustments...

good luck with eBay,
