1. Two images of Neptune side-by-side. The left one is sharp, showing white clouds on a blue disk against a black background. The image is labeled "Adaptive optics". The right image is completely blurred, no details can be discerned on the planet. This image is labeled "No Adaptive optics".

  @thomasfuchs These are real images with the AO on and off, taken with the MUSE instrument at the VLT a few years ago. MUSE gives you a spectrum at every single location within its field of view, so the amount of information that you get is huge. You have more details here: https://www.eso.org/public/news/eso1824/

    Supersharp Images from New VLT Adaptive Optics
    
    from @ESO
    
    ESO’s Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography — and has captured remarkably sharp test images of the planet Neptune, star clusters and other objects. The pioneering MUSE instrument in Narrow-Field Mode, working with the GALACSI adaptive optics module, can now use this new technique to correct for turbulence at different altitudes in the atmosphere. It is now possible to capture images from the ground at visible wavelengths that are sharper than those from the NASA/ESA Hubble Space Telescope. The combination of exquisite image sharpness and the spectroscopic capabilities of MUSE will enable astronomers to study the properties of astronomical objects in much greater detail than was possible before.
