The image shows a transmission polarizing microscopic texture of a cholesteric liquid crystal (CLC) with negative dielectric anisotropy in a cell with a homeotropic boundary condition at a magnification of x100. The CLC sample was dispersed with 10um microparticles and applied with a low electric field which is perpendicular to the cell substrates. The polarizers were crossed with an angle about 150 degrees. The sample was observed at room temperature.
Jury comment: It is a beautiful blue texture and with the microparticles it does indeed look like stars in a dark sky with a shooting star with a red trail present
