Hi Steve, Andy,
Thought I’d add one more to your impressive collection – as well as AG Pegasi & Chi Cygni I chose to follow CH Cygni. Even at low resolution CH Cygni is a real gem for a beginner to follow and try to understand – changes in the spectrum abound – this plot shows changes to H and He lines in just a month [He disappear!]. I used iota CYG as reference. Wondered if you could give some tips on how to normalise in situations like this when continuum so broken up?
