Scott, just got through watching the June 10 Zoom, thanks for your presentation on spectroscopy. I just finished up the Choice course Introduction to spectroscopy presented by Steve Shore @ U. of Piza. His lectures were anything but introductory…mostly on interpretation of spectra, and very little of that. What I was wanting was QC for submitted spectra to AAVSO, (is this spectra OK for AAVSO.) I also sit in on the spectroscopy remote telescope zooms and plan to make a donation for the scope. When you start talking programming and writing code you loose me, but otherwise well worth my attendance. Thanks for all your efforts!
