Zoom of the Sun
Zoom of the Sun from full disk to 0.1 arcsecond (70 km)
resolution. The full disk image comes from the MDI instrument onboard
the Solar and Heliospheric Observatory (SOHO) satellite, the high
resolution end image comes from the
Swedish Solar Telescope (SST) on
La Palma. This high resolution image was taken in the G-band filter on May 25 2003 at
11:22:32 UT by the Oslo group (Mats Carlsson, Astrid Fossum, Viggo
Hansteen, Elin Marthinussen, Luc Rouppe van der Voort) and is one of
the sharpest images ever taken of the Sun. The image is a combination
of three images using Multi Frame Blind Deconvolution but even the raw
images before deconvolution are diffraction limited over most of the
field of view. The zoom goes through an intermediate resolution image
from MDI. The seamless zoom was achieved by smoothly interpolating between
the three input images during the zoom. The axes are in arcseconds. Image processing by Mats Carlsson.
