TL;DR: The Extreme-ultraviolet Imaging Telescope (EIT) as discussed by the authors provides wide-field images of the corona and transition region on the solar disc and up to 1.5 R⊙ above the solar limb.

TL;DR: The Extreme Ultraviolet Imaging Telescope (EIT) on board the SOHO spacecraft has been operational since 2 January 1996 and has been used to observe the Sun over a 45 × 45 arc min field of view in four emission line groups: Fe IX, X, Fe XIIi, Fe xv, and He II.

TL;DR: In this paper, the first observations of the initiation of a coronal mass ejection (CME) seen on the disk of the Sun were presented, where the CME was initially associated with slow motions of prominence material and a small brightening at one end of the prominence.

TL;DR: Kirkpatrick and Baez as discussed by the authors developed an x-ray microscope (energy range about 100 eV-10 keV) composed of two concave spherical mirrors working at grazing incidence that presented a 3-5 μm resolution within a field having a radius about 100 μm; outside that field, its resolution lowers rapidly when the object point recedes from the center.

TL;DR: In this paper, the fabrication and test of the primary and secondary mirrors of a Ritchey-Chretien telescope designed to provide the SOHO mission with a global view of the solar corona are discussed in details.
