Hi,

Getting redshifted P-alpha filters for GRIM2 is, of course, quite
interesting and useful. However, having a few fixed wavelength 
filters would cover only a limited redshift range. I suggest we 
entertain the idea of having a CVF (circularly variable filter)
to cover a much larger wavelength range. This could be used for 
narrow-band imagig in other lines as well.

Zlatko.
