Thanks to Ken (merlin66) for doing some work on my spectra, I've been having a bit more of a play with Visual Spec... Still finding my way round and its all baby steps...

Still heaps to learn, and I couldn't have gotten this far without Ken's help

... I'd still be trying to match up lines that just aren't meant to be

.
The spectra are my raw capture for Antares (blue line), a reference spectrum from the library (Green line - M1III is about the closest I could find

), my first attempt at the reponse of my ToUcam (Orange line) and the corrected spectrum (brown line - actually its only corrected for the camera response not atmosphere as well

) ...but I'm getting there!


Some of it is a bit hit and miss, because the tutorials must be written for an earlier version of the program

because the menu options don't match

.
The second image are synthesized colour spectra produced from Visual Spec - not as captured. Cool feature that!
