Spectroscopy at Virtual Telescope was officially started at the end of Nov 2012, when a diffraction grating was made available on the Celestron 14 robotic unit.
Since then, several spectra were obtained, both for refining/fine tuning the system and doing science on special targets, as novae and supernovae.
The system has proven to be very flexible, able to offer quick spectroscopy as soon as a given transient is detected.
The amazing tracking capabilities of the robotic mount makes possible quite long integration, collecting enough signal to investigate relatively faint objects, with a dispersion of ~34 angstrom/pixel. For data reduction, we use RSpec.
Below, a list of spectroscopic works done with our telescope is provided.
