Chemical Elements as Tracers of the Evolution of the Cosmos

Ondrejov Perek 2m Telescope

The Perek telescope has a primary mirror with a diameter of 2 meters and is equipped with a single-order and an echelle spectrograph.

The Perek 2-m telescope is located 30 km south-east of Prague. The telescope itself is maintained and operated by the Astronomical Institute of Czech Academy of Sciences (ASU). The telescope has a primary mirror with a diameter of 2 meters and is equipped with two instruments, a single-order spectrograph and an echelle spectrograph.

The Ondřejov Echelle spectrograph (OES) offers a unique proprietary access to spectrograph with medium and high resolving power. The OES is a fiber fed echelle spectrograph and can observe in range from 380-900 nm with a spectral resolution about 40000. The accuracy in radial velocities can be down to a few tens of m/s. The limiting magnitude is roughly Vmag=13. The single order coude fiber fed spectrograph has a spectral resolution of about 13000. The wavelength coverage is in three different wavelength ranges of: 6350-7910 Å, 4800-9000 Å, and 3500-5500 Å. On average, the infrastructure can offer between 80 and 130 clear nights a year.
