 a Generation 3 .   Hard coated ;  1 angstrom 393.37nm filter developed by Apollo Lasky        (these are supposed to be available for purchase at http://calcium.solar  but i am not sure when.)

Basler 1920-155um camera for imaging.

  

 

 

 

And here is an interesting reference image from paris meudon observatory.   

this is a diffraction grating slit image,  with .1 angstrom bandwidth.
