Shelyak Spectroscope LISA Visible (54328)

The Shelyak LISA Visible spectroscope is a low-resolution, high-luminosity instrument designed for astronomical spectroscopy in the visible light range (400–700 nm). With an f/5 optical system and a resolution of approximately R~1000, LISA is well-suited for capturing faint objects and delivering high-quality spectra. Its design incorporates a focal reducer for maximum light efficiency, making it ideal for both research and advanced amateur astronomers. The spectroscope comes with a custom-foamed carrying case for secure transport and storage.

This version of the LISA spectroscope is optimized for observations in the visible spectrum, but a near infrared version is also available for expanded applications.
