Sharper than Hubble: Large Binocular Telescope achieves major breakthrough

All,

Thanks H.

Expecting 10 times sharper than Hubble when both mirrors are commissioned!

Going to be breathtaking when it is all fired up.

These test results are outstanding.

It must be very frustrating to have two 8.4 metre almost perfect mirrors to end up with a Strehl of 1% due to the atmosphere.

Their results look impressive. Could be useful to directly image extrasolar planets.

A quick calculation gives about 325mm diameter area on the main mirror for each actuator on the corrector.

thanks H

The concave secondary mirror is 0.91 metres in diameter (3 feet) and only 1.6 millimetres thick.
I would be happy to take that as my primary mirror!
How do you grind such a mirror?

So, do you reckon the Hubble will turn up on eBay ? (Given that it'll soon be obsolete) !

- Perhaps even on the Iceinspace 'Telescopes and Mounts' board !

Mind you, the mount could be a problem, especially if the primary is so thin.



Cheers

I wonder what sort of webcam would be suitable for the Hubble as an imaging device

The best thing about this is that next scope generation might all be ground based. Massive savings in maintenance and upgrades, size, pretty much everything. Exciting times.

I wonder what portion of this technology will spawn off into military equipment to create volumes, and then consumer goods when the volumes bring down prices. Maybe it is a sign of things to come.

I recall retinal tracking used by air force pilots for pointing weapons just by looking at the target with their eyes and not having to move their head, 3 years later Canon had it in their /eos5 cameras, it focuses where you look in the view finder.

Big draw back for these guys will be global warming and the potential for more clould cover where they have built their telescope.
