Main Article Content
Abstract
The paper describes the high-resolution echelle spectrograph ESPL developed for the coude focus of the 2.6 m Shajn reflector of the Crimean Astrophysical Observatory. The spectrograph has been regularly operated since 2013. Efficiency of the spectrograph is estimated from observations of stars.
