We evaluate a pre-production BACHES ´ echelle spectrograph in terms of its usefulness for radial velocity surveys of binary stars with small telescop es in a remote and autonomous. We use the Solaris-4 observatory located in CASLEO, Argentina, that is part of a global network of autonomous observatories as the test-bed for the instrument. The setup is designed in such a way that spectroscopy and photometry can be carried out using the same telescope without the need to mechanically modify the… Expand
