he diameter of the Hubble Space Telescope is 2.4 meters; the diameter of the new Chilean telescope is 9.6 meters.
How many times better is the theoretical resolution of the new Chilean telescope (the best possible resolution that the Chilean telescope could achieve if nothing else outside of the telescope itself acted to make the resolution worse) compared to the theoretical resolution of the Hubble Space Telescope? Again, show your work or explain your reasoning.
In principle, the resolution is estimated by lambda/D (wavelength/Diameter of aperture) so the new telescope has, in principle, a resolution 4 times better than Hubble. However, as far as I know, these (the VLT’s) have a 8.2, not 9.6 aperture. On the other hand, they have adaptive optics to compensate for atmospheric turbulence which gives them a resolution up to three times better than Hubble in the IR
Note added: Apparently people don’t like the superiority of Hubble being challenged. However they should check facts, And what I said above concerning the VLT equipped with adaptative optics is hardly questionable.

How do you get into astro photography? How do you connect to a telescope.
Purchase: http://hilaroad.com/video/ This video demonstrates how to find the Andromeda Galaxy (M31). This galaxy is 2.5 million light years from earth but with some basic knowledge of the night sky and a pair of binoculars it is actually possible to see it! The video is designed for anyone interested in astronomy and it also provides support for the astronomy component of any science curriculum.
A movie from the Hubble telescope
The Meade #902 Electronic Eyepiece transmits live, black-and-white images of the moon, planets, and terrestrial subjects from your telescope to a TV monitor, VCR, or camcorder. Made to fit 0.965″ or 1.25″ focuser sleeves, the eyepiece includes a 6-foot cable and requires a 9-volt battery that installs neatly inside the eyepiece housing. Contrast adjustment is built in.
