Re: [ATM] convex secondary
I meant to say that there were two green emission
**lines** right next to each other in the green part
of of the spectrum. I don't understand the physics of
this well enough to explain why this happens. I also
misspelled 'fluorescents' and 'reasons'.
I bought some theatrical filter gels to filter out the
unwanted wavelengths; went to a theatrical supply
house to get them.
