Abstract
The TEREK imaging telescope installed on the Phobos-I spacecraft, and the TEREK-C telescope and spectroheliometer, designed for use in the Coronas project, are examined. In comparison with the TEREK instrument, the TEREK-C has an improved spatial resolution in the MX channel of up to 2 arcsec. The main parameters of the TEREK-C and the spectroheliometer are presented in tabular form, and an optical scheme of the TEREK instrument is given.
