Abstract

(Abstract only) Some observations which explore the capabilities of three popular spectrograph designs: 1. Simultaneous multi-band photometry of fast transients using a Star Analyser grating; 2. Confirming and classifying magnitude 17 supernovae using an modified ALPY spectrograph; 3. Sub km/sec precision radial velocity measurement using a LHIRES III spectrograph.
