Hope this helps.

I know it's stating the obvious but just be careful mucking about with
240v.
In the darkness, on a wet lawn/ dome using a scope etc....not
a good environment for 240v.
It's a pity about neons, they need about 40-80v to work.
I got mine (for the spectroscope calibration) from a 2nd-hand
powerpoint that had neons on the front.

here for some pics of it through a webcam:
