Quote from: RobertM on May 30, 2022, 09:01:44Interesting that you used Vega as it is generally taken as a reference star for spectroscopy due to its colour and emissions spectrum. I used it as part of my spectroscopy project for the OU a number of years ago. If you want to calibrate your spectrograph then I used a He-Ar hollow cathode lamp - I've no idea if these are expensive though.Robert
