Miracle flocking for telescopes. Vantablack.

The company says Vantablack was the darkest material ever tested by the National Physical Laboratory in the UK, as well as the Institute of Standards and Technology in the U.S.

The material is made up of millions of carbon nanotubes, each measuring two or three nanometers -- or roughly one millionth of a millimeter. It is grown on aluminium foil.
Creases and bumps on the foil are easily picked up by the human eye. But once covered with Vantablack, all wrinkles and roughness seem to disappear.

Instead, the material is designed to help air-borne cameras, telescopes and infrared scanning systems work more efficiently by reducing stray light. Military clients are lining up to buy it, as is the space industry.
The benefits, Northam said, are that "your systems can see fainter objects further away, you improve the sensitivity and you improve the signal to noise ratio in these systems."
I wonder when we can buy this & how much it will cost?
