Hi Robin,Many thanks for all the information and links. I’m relatively new to spectroscopy so any help/encouragement is most welcome!An objective prism appealed to me as I could simply put it in front of my existing imaging equipment without modification and it gives a single, bright spectrum. Luckily Bob Marriott dug one out of the BAA instrument collection for me to play with.Regarding the spectrum…I’m curious to know what the lines between about 520 and 540nm are due to? And you mention CN emission…what wavelengths will they appear at?By the way, I initially had trouble getting my image to appear until Roger Pickard put it on the VSS web page and I could link to there.When I get some more results I’ll let you know.Thanks again,Mike.
