Such sensitivities are only available now with the NuSTAR satellite [launched in June 2012] which is designed to create

sky sharper than ever before,» he adds.
The Sloan survey captures the
sky in full color rather than just through red and blue filters, produces
images twice as
sharp as Palomar's, and detects objects one - tenth the brightness
of those detectable by its predecessor.
Astronomers have taken the
sharpest image yet
of the
sky at very long radio wavelengths.
Although observatories are built at sites that typically have clear
skies and relatively calm air layers, the only ways to get truly
sharp images is go above the atmosphere (think Hubble Space Telescope) or to build highly complicated adaptive optics systems that correct for the atmospheric turbulence (and even most imperfections
of the telescope itself).
The iPhone did a better job overall with this tricky
image of the Flatiron Building, as the flower in the foreground is
sharper and the blue
sky and clouds look realistic.
