If you folks in the UK have a welding supply shop near you, you can always get a welding lens. That's what I use here on those occasions when I can view an eclipse.

Get either a number 10 or number 11. Number 9 and under are too light (in my opinion) and you don't need anything darker than an 11. You don't need the whole hood or goggles, just the lens, and the lenses cost about $3 here in the US.
Sorry to say but : That's was not the Moon
