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: In this article, the EIT (Extreme ultraviolet Imaging Telescope) images the Sun's corona in 4 EUV wavelengths, including the chromosphere and the base of the transition region at a temperature of 5 − 8 × 104 K.

TL;DR: The design of the multiband-pass Extreme-Ultraviolet Imaging Telescope designed for 1996 launch on board the Solar Heliospheric Observatory is described in this paper, where images in four narrow bandpasses at wavelengths ranging from 17 to 31 nm are obtained using normal-incidence multilayer optics deposited on quadrants of a Ritchey-Chretien telescope.
