Francois Cochard is a french amateur astronomer, and co-founder and manager of Shelyak Instruments Company.
Spectroscopy is the study of electromagnetic radiation wavelengths, each of which is emitted by an object or produced through an object’s interaction with other matter. In spectroscopy, a spectrum is a range of light separated into different wavelengths, each which projects a unique brightness. Observing stellar spectra can answer questions poised in human minds since our collective eyes first gazed starward.
Beginner to experienced spectroscopists are encouraged to submit data to AAVSO's spectroscopy database, AVSpec. Crucial data can be observed and uploaded to the databases with and without high-tech equipment. If you want to get started in spectroscopy, join in this webinar, complete with an audience (that's you!)-driven Q&A.
Cochard organizes the Spectro Star Party every year at the Observatoire de Haute Provence (OHP), assisting a lot of observers in their first steps in spectroscopy, so his instruction is a great place to begin your spectroscopy journey (or even figure out if spectroascopy is right for you)!
And if you're into the technology of spectroscopy, you'll be happy to know that Cochard was deeply involved in in the design and the manufacturing of instruments that are today considered standards, such as Lhires III, LISA, eShel, Alpy 600, and UVEX.
