Scientific paper
Two sounding rocket test flights have been conducted in the development of an image drift compensation system designed for a solar-pointed space telescope. The system, whose scientific results are presented, employs limb-sensing photodiodes at the telescope focal plane and provides drift compensation to better than + or - 0.1 arcsec. A variation of this device will be employed by the Space Shuttle/Spacelab 2 flight of the High Resolution Telescope and Spectrograph (HRTS) Instrument. The data gathered by the rocket flights of the drift compensation system have revealed high velocity ejecta traveling through the transition zone and corona at velocities up to 400 km/sec. The HRTS configuration and its constitutive instruments' optical parameters are described.
