Astronomy / laser p**n

Some of the photos in the first link are pure p**n

22w of 589nm, someone has very deep pockets

Amazing stuff

Telescopes with frickin laser beams.

I wonder how they operate around flight paths. People get bollocked for firing laser pens at the sky at night for fear of blinding pilots.

That's not even considering the space ships which will be crashing left right and centre due to having their retinas burnt.

After reading that I still don't know what the f**k it's used for. It's cool though!

Faking stars ;-)

They say its for faking stars but anyone who has ever watched Star Wars will know what they are really doing is creating a death star cannon.

 

[Aaron..]

Why the need to fake stars?
All they need to do is create weather machines to remove all of the clouds...

Yer but why lol

Yer but why lol

I can't believe you don't know.

Did you go to school ?

What a moron.........







Nope, I have absolutely no idea either. Looks fekkin' excellent though.

FRIKKING SHARRRKKKS, WITH FRIKKIN LAAAAZER BEAAAAMS...

oh come on, if you don't understand this your just fick

The 4LGSF is part of a next-generation adaptive optics system, the Adaptive Optics Facility (AOF), that will make the VLT’s 4th Unit Telescope Yepun a fully adaptive telescope in 2013. Composed of four powerful 20-watt lasers, the 4LGSF will help the VLT correct the image distortion caused by turbulence in the air.

Telescopes usually collect light coming from the sky and focus it into an instrument. However, the new components send light in the opposite direction. These “launchers”, are used to project the lasers into the sky to create brilliant points of light. The laser beams excite a layer of sodium atoms at an altitude of 90 kilometres in the atmosphere and make them glow. These glowing spots act as an artificial guide star which can be positioned at will in the sky, so astronomers are not restricted to observations close to a sufficiently bright natural guide star.

With four such artificial stars, the 4LGSF will be able to dramatically improve sharpness [1] across the wide field of the VLT’s near-infrared camera HAWK-I. Single laser systems, although providing excellent image quality, are restricted to much smaller fields of view

The first such system on the VLT was installed just over ten years ago. In early 2006, the technology was improved with the first use of a laser guide star at the VLT.

basic stuff right

Lol, Ffs.

@andy_con last year at We Are, what stage/acts did you do lasers for?

 

[Andy_con]

Lol, Ffs.

lol my limited understand is, its to help telescopes focus better

@andy_con last year at We Are, what stage/acts did you do lasers for?

none, my son was born on that weekend so I had to miss it
I'm currently in talks with the wife about this years festival and my sons first birthday.

but both outdoor stages were done by the people I help last year

Ah, that was selfish of him! The festival was amazing, as were the lasers, especially for Steve Angello/Knife party. Sad to not be going this year.

yeah they did steve and knife party

I was there the first and second year, I was on stage with fat boy slim faffing around
