The lens

The lens
Do you think that you have some pretty good lenses? Well, not many lenses would beat this one - it is the Fresnel lens that once graced the Montague Island lighthouse, before the new halogen lighting was installed. At a guess it stands 5 M high and the glass section used to float on a bowl of liquid mercury as it rotated. Now it sits in the tourist information office at Narooma, the nearest town to Montague Island. HFF and have a great weekend, everyone.

Good record of the lens. That was a LOT of mercury to have sitting around. Maybe it was the reason light keepers went mad, rather than loneliness?

I'm pretty sure that it wouldn't pass the OH&S requirements these days!
