Ten years ago the SST captured its first diffraction-limited image, demonstrating the quality of the telescope. This was within days of first light with its full aperture.

During the past ten years the SST has had its instrumentation continuously amended and improved. Currently its adaptive optics is undergoing an upgrade which is expected to increase the fraction of time with diffraction-limited performance.
