Mixed-polarity magnetic fields in the same resolution element of bi-dimensional
solar images are known to produce an artificial magnetic flux
cancellation. This effect often prevents us from investigating the rich
dynamics of small-scale magnetic flux concentrations revealed by the
sharpest observations of the solar atmosphere.
In this contribution, we report on a selection of science...
The 4-m class European Solar Telescope (EST) shall be provided with powerful MCAO to achieve the required > 80 arcsec corrected FoV. The EST MCAO system shall use large format high speed WFS detectors running at up to 2 kHz. We present a possible solution for multiplexing the wavefront sensing by splitting the pupil plane on two or more detectors that sample different regions of the pupil...
