  In order to study the solar corona during eclipses, a new telescope was
constructed. Three coronal images were obtained simultaneously from one
objective of the telescope as the coronal radiation passed through three
polarisers (whose transmission directions were turned through 0^{\circ},
60^{\circ}, and 120^{\circ} to the chosen direction); one image without
polariser was also obtained. The telescope was used to observe the solar corona
during the eclipse of 1 August 2008. We obtained distributions of the
polarisation brightness, K-corona brightness, degree of the K-corona
polarisation and total polarisation degree; polarisation direction depending on
the latitude and radius in the plane of the sky was also obtained. We
calculated radial distributions of electron density, depending on the latitude.
Properties of all these distributions in different coronal structures were
compared. We determined temperature of coronal plasma in different coronal
structures on the assumption that there is a hydrostatic equilibrium.
