The Sun's Chromosphere

Abstract

Is there any way, by means of an ordinary telescope with coloured glasses, of seeing the red prominences on the sun's edge —that is, without a spectroscope? If so, what coloured glasses ought to be used? In one of the former numbers of NATURE, an observer saw, with only a telescope, what he believed to be these prominences; the sun was near the horizon, a series of rose-coloured undulations became visible, unconnected, as supposed, with atmospheric disturbance, and which it was suggested might be due to the red flames of the chromosphere
