Filter mix up

[RonP]

I have managed to mix up my unmounted narrowband filters.

can anyone suggest a positive identification method to sort me out ?

Have a look at images of the filters on Baader, Astrodon etc sites and hope you can match their colours to yours ?

What filters are they (make and bandwidth), are you talking the usual Ha, OIII & SII?

I am not sure all makes are the same but my Baader and some unbranded ones the OIII looks  Green when you look through it at a light source

Ha and SII both are Reddish / Magenta but would say the Ha is more towards the red and the SII more towards Magenta but that is very unscientific and not very helpful.

As they are unmounted are the edges at all different colours that you can match to pictures on FLO or similar as Michael suggests?
