“…A common problem is the need to reduce the contribution of scattered light and ghost images. A new spectroscopic device, which prepares the comparison spectrum, is proposed for the two fiber spectrograph scheme (Panchuk et al, 2018).…”
We briefly present the history of technical solutions aimed at improving the efficiency of spectroscopy on small-and moderate-diameter telescopes. We assess the current state of spectroscopy techniques and some of the perspectives.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
