Regarding the recent fading of V705 Cas and comments made by Mr. Kato on this
star's current 'nebular phase', observers with an OIII or Lumicon UHC filter
may want to try an interesting experiment. These filters will easily enhance
this variable's brightness in relation to other field stars. By alternately
moving the filter back and forth over the view, V705 Cas will appear to
brighten and dim much like a stellar planetary nebula. It is a fascinating
way to witness this star's OIII emissions.
