The telescope is designed for high-resolution spectroscopic, photometric and asteroseismic stellar observations.

 

Main technical characteristics:

1.65 m mirror diameter Ritchey-Chrétien telescope. Remote control option installed. Spectroscopic observations are performed with an echelle fiber optics spectrograph (spectral range from 400 to 880 nm; resolution 30000, 45000 and 60000; light detector e2V CCD 231-84, 4Kx4K with -94 C operating temperature). Photometric observations are performed with CCD camera E2V CCD47-10, 1024x1024, pixel size 13 microns; U, B and V filters.

Applications:

1. Determination of stellar atmospheric parameters and chemical composition.
2. Monitoring of exoplanet transits.
3. Observations of stellar variability and asteroseismic activity.
4. Measurements of stellar radial velocities.
