A coronagraph is a telescopic attachment designed to block out the direct light from a star or other bright object so that nearby objects – which otherwise...

Spectrometric Coronagraph (LASCO) on board the Solar and Heliospheric Observatory satellite (SOHO) consists of three solar coronagraphs with nested fields...

A vortex coronagraph is a type of optical instrument for telescopes that blocks out the glare of bright objects (like stars) so that smaller objects near...

the use of the NRO telescopes. The Roman baseline design includes a coronagraph to enable the direct imaging of exoplanets. Several implementations of...

stars than conventional Lyot type coronagraph designs. For example, at a distance of 100 pc, the PIAA coronagraph on SCExAO would be able to image from...

LUVOIR would be equipped with an internal coronagraph instrument, called ECLIPS for Extreme Coronagraph for LIving Planetary Systems, to enable direct...

multichannel imager, an integral field spectrograph, and a cool planet imaging coronagraph. The survey camera is also known as the multi-color photometry and slitless...

precisely cast its shadow onto the Coronagraph’s telescope, blocking the Sun’s direct light. This will allow the Coronagraph to image the faint solar corona...

solar disk to explore the core of the Sun. Large Angle and Spectrometric Coronagraph (LASCO), which studies the structure and evolution of the corona by creating...

However, the estimated mass values for CMEs are only lower limits, because coronagraph measurements provide only two-dimensional data. CMEs erupt from strongly...
