Not only that: he said it would be "very expensive" So it absorbs all money, too.

At 7.5x the thermal conductivity of copper and ten times the strength of steel, that is going to make a very light telescope that cools very quickly. It also strikes me that not only would it be possi

well here's one sad old goth astronomer willing to test this little beauty out  :grin:

i actually have a black t-shirt with black lettering that says 'I only wear black until they invent something darker'

and so, it has arrived  :grin:

I think it stated 0.035% reflective, but yeh the energy has to go somewhere so it's gonna get warm.

Money absorbent is pretty much standard for astronomy gear >.<

It also strikes me that not only would it be possible to make a complete hash of flocking as you can't see what you're doing with it. The corollary is that nobody would be able to tell!

I wonder if Wilkinsons will stock it?

Not significantly warmer than other dark materials.

Simple black acrylic paint is about 5% reflective, and this material would only absorb a little over 5% more energy than that. You probably wouldn't really notice the temperature difference (and that's ignoring the increased thermal conductivity),

Perhaps Black Holes are just another species throwing loads of this away because they have so much for their telescopes that they don't want anymore material :D.

I thought real goths were 800 yrs old ;)

Now if they could make a similar material that transmits 100% of the light with zero reflection that would be good if only you could find it once you had put it down.

Got an email from the vantablack people today...

'Please note however, that Vantablack® has been developed to address a number of highly specialised applications. The coating is formed from a nanostructure array and as such is not suitable for consumer goods, or handling by the general public – despite what the global press may have suggested.

In particular, the material is currently only suitable for coating surfaces that are not normally exposed to the elements (i.e. rain or snow) or to human contact, any of which are likely to damage the material's optical properties. It also carries a UK government export restriction, so can only be supplied to corporate users or research labs that the UK government deems appropriate.'

Ho-hum...

This looks like the results i got the last time i baked a cake:

Any luck flocking your scope with it? ;)

TSED70Q, iOptron Smart EQ pro, ASI-120MM, Finepix S5 pro.
