The difference in clarity is dramatic and represents the realization of the anticipated quality of images from a space-based, optical telescope. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/m100after/m100after.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/m100before/m100before.dc.xml This image was taken before the optics was fixed and demonstrates that the optical error generates images that are not much better than images taken with ground-based telescopes and were much less clear than expected. The picture is from the Wide Field and Planetary Camera 1. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/m100before/m100before.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
