Welcome to the omnibus order for the Littrow High Resolution Spectrograph (LHIRES) III coordinated by the Professional Group for Spectroscopy of the Swiss Astronomical Society. The LHIRES III is a field-proven high-resolution spectrograph for small telescopes with flexible connectivity to all types of CCD and SLR cameras and webcams. It also doubles as a spectroscope for viewing spectra live through an eyepiece. The instrument is a must-have for astronomy clubs, individual astronomers and educational institutions wanting to introduce a variety of audiences to the rich information transmitted by light. The spectrograph has been a key instrument of astronomical practice in the modern era. Here is your chance to acquire one at an affordable discounted price. The LHIRES III performance depends on the specific configuration. For instance, the LHIRES III would show the following performance parameters with a 8'' f/10 telescope, 1h exposure, 30µm slit size, target signal/noise ratio of 100 and a KAF400 CCD chip.
