Abstract

The instruments on board our Normal Incidence X-ray Telescopes payload and the results obtained during the most recent flights will be described. The payload was launched three times during the 1991 - 1993 period, the last time on April 12, 1993. It contained a main telescope with an 11 inch diameter multilayer coated mirror for (lambda) equals 63.5 angstroms and photographic film as detector. Smaller telescopes for either (lambda) equals 304 angstroms or (lambda) equals 193 angstroms used electronic detection and direct transmission of analog or digital data to the ground station. The flight on the day of the solar eclipse in July 1991 gave us an opportunity to perform a soft-ray knife edge test with the limb of the moon. From the experiment we derive upper limits for the figure errors of the telescope mirror, and we conclude that large mirrors with diffraction limited resolution better than 0.01 arcsec can now be fabricated.
