I ran across this when looking for a supplier for Vantablack.   This paint is supposed to be very close!   I'm thinking about ordering a bottle and giving it a try.

I'm building a Carbon Fiber telescope....this would paint the inside of the tube.  

 

Anyone hear or use this before?

[NiteGuy]

Looks like outstanding stuff. Since Vantablack is simply not available yet, unless you know somebody who knows somebody who knows somebody at Area 51. Black 2.0 is just what I've been trying to find for a couple of scope builds. Does this company have a US distributor for their product?

Interesting stuff Brett.....but what I Really want to know is,.......who in the heck is Anish Kapoor, and what did he do?   

[jimr2]

"Black-cherry" scented--WHY??!!! Not sure I want my scope to smell like black-cherries forever and after!

[barbarosa]

His views on populism (right version bad, left version good), immigration (Indian born lives in the UK) and Brexit (not a supporter).From which we might conclude that the seller has different sentiments.  EDIT- The explanation in the post that follows is probably the better one.

 

The important thing for amateur astronomy though is--

• Black cherry scented
• Priced at what it costs to make

Is the world ready for a scented telescope? If the answer is yes, the company ships via  mail. £25.38 per 150ml bottle to your (US) door.

Anish Kapoor has the exclusive rights to Vantablack, the blackest black on the planet.  Artists everywhere are disgusted with him.  Thus the negative press.

 

Not sure if his exclusive rights exclude ATM folks or not.

[Brett Carlson]

I've ordered a bottle so I'll test paint something and let everyone know! Looks pretty cool.

Black cherry? I was wondering that myself!

[GlennLeDrew]

I'm curious about its performance at grazing incidence.

[havasman]

Very interesting. Please report your results!

Not trying to hijack the thread, because this paint sounds like exactly what we're looking for, but how do you guys apply the flat black paints? I hear most people cover the outside of everything with polyurethane, expoxy, or polyester enamels like they're going to sea with their telescopes. But with the black paint, do you just use the black paint and nothing else? When painting my last telescope with layers of enamels it felt like I overdid the outside, and undid the black inside. Though I suppose any exterior grade paint should be fine, right?

The scope I'm building has a carbon fiber cylinder to protect the mirror.   This is what I'll paint with the Black 2.0.   The inside will not be bright glossy carbon fiber.  The inside will be rough and should take a flat paint well.   I have a test piece ready.   Once I receive the paint I'll test it and let everyone know.  

[Benach]

Just out of curiousity: how are you going to test this?

[Joepie]

Oh, this is looking very promising. I might buy some as well...

[Joe1950]

Black 2.0. 150ml. I ordered a bottle. It came to £19.23 or $24.75, shipped, via paypal. 

 

I have a couple areas in eyepieces that need a real dark coating. I'll have to test it, watch for outgassing. It is an acrylic based paint, so it shouldn't be too bad.

 

Let ya know how it works. Cheerio!

 

Can't get that Vantablack.   But we have VantaWhite!

I like the Anish Kapoor comments.

[musicengin]

Poking around a little more, it appears that Kapoor is in the process of testing the Vantablack for the purposes of artwork, and has exclusive rights to do so because the company that produces the stuff doesn't think it would work well in its present formulation for the general public/artist community.

 

So it sounds more like a kind of alpha testing/product tweaking process, that has created a bit of a tempest in a teapot in the art world; but if it is really about moving the product towards more tractable for the average user, then I'm all for it.   I like drippy sticky annoying stuff to be as un-annoying as possible.

[Brett Carlson]

OK....I received my Black 2.0 and painted a few test objects.   

 

I painted one Rubber ball and two pieces of Carbon fiber that will have the same finish as the pieces I'll be using.

 

Here are the two pieces before painting

here are the two pieces after 36 hours of drying,  2 coats with 3 hours of drying time between the two.

It's not the "Black Hole" effect I was looking for but it is pretty effective for flocking paint.

Brett,

 

do you have a green laser pen?

If so can you try to shoot the laser at the stuff in a dark room to see how it reflects?

 

Looks pretty much like some decorative black paint that I can buy at the Home depot/Construction Marked.

The paint I'm thinking of is one that makes the painted surface like a blackboard from school.

Has a raw texture to it but not as black as you would expect - just like your test shows.

I have used it paint the inside of telescopes with success but the protostar flocking velvet adhesive stuff is better.

I'll try the green laser and a weaker red laser.   When I saw that test with the Vantablack I assumed it was a function of the nanotubes.   I'll give that a show and let you know.  

 

Any other tests anyone wants to see?

Not me, but I would like to know more about your CF tube. Do you have a thread started already?

[jrslivon]

When I was working on stereo cameras about 20 years ago the best light absorbing black spray paint that I could find was Testor's 1249 flat black spray enamel. Unfortunately it seems to be available only in 3oz. spray cans. I don't know how it compares to all the more modern flat black paints on the current market but it might be worth a try. I have an old can with a Wal-Mart price tag of $2.97. I think it's less than $6 now. Application may be the real challenge.

Brett,

 

Again, thanks for posting all this up. I have a bottle ordered too and am glad to hear that it does actually deliver. In Semple's how-to-use video he refers to a recommended varnish overcoat that makes Black 2.0 capable of outdoor use without adding gloss. I have not gotten an answer from him about what varnish that is. My intent to paint the inside of the Starmaster mirror box with Black 2.0 kinda makes that a borderline outdoor application. Do you know what varnish he's talking about?

 

Your pics are helpful. The painted carbon fiber may not be Black Hole black but it looks really flat and non-reflective. That should be beneficial.

 

I'll tag onto your string here when I get some reportable results.

I have it in a old thread from last year.   Basically I'm taking a Meade Starfinder 16" and making a light weight replacement out of Carbon Fiber.    

 

The general plan is to make is look something like this but with the strut at the pivot point.

 

https://www.instagra...aken-by=brett2c

 

Then cut the strut and make pivot points so the scope can fold in on itself and be even more portable.   Like this:

The idea was to make this portable like a strut telescope but with less setup time.

[wrvond]

Thanks for the information!

Brett,

The culturehustle website shows a test in the panes on the right edge of the page.

 

Your ball isn't "blackhole" black beacause the majority of your lighting is in front of the ball. You can see it's really FLAT, but not really how dark it is.

Try backlighting the ball and then taking another picture. I have a feeling it'll be a whole lot 'blacker'.....
