What equipment have you got that's worth its weight in gold?

[PeteC]

My new AtronomiK CLS clip filter arrived yesterday. On taking it out of the jiffy bag, my first impression was so much money for something so small. I decided to weigh it - 5 grams. I paid £130 for it, so that's £26 per gram. I just checked the gold price and that's £25.30 at the moment. So my little filter is worth its weight in gold!

That got me thinking, is there any equipment out there that's even more expensive on a £ per gram basis? I thought maybe a CCD, but I just checked a 314L and that's not even close to my filter at less than £3 per gram. Anyone got anything else that's worth more than its weight in gold?

I could use this to set the handset clock as it is worth its weight in Gold, 24ct made in 1918, no internal inscriptions.....

I don't know the weight of an Astrodon 3nm 50mm square filter, but at close to £1000 in cost it must be considerably more valuable than gold.  And that is one reason why I don't have one.

My green laser pointer and my home made bahtinov mask could not do without them and my ASTROEQ mount controller best thing I ever bought.

I think you're missing the OP's point here chaps, he's suggesting you weigh your item and compare its price to the same weight of gold.

I wish my counterweights were made of gold....

My Nexus, it weighs 5oz so that makes it about $50 per ounce. Not as much as gold but my most expensive anyway

If I were to buy any phone apps, they'd be worth infinitely more than their weight in gold.

Thanks Peter. We all have indispensable bits of kit that are "worth their weight in gold", but the Astronomik CLS actually cost me a bit more than its weight in gold and I was just wondering if there is anything even more expensive on a £ per gram basis that anyone owns. Just thinking about it, it's probably going to be some high end filter.
