The was a first light image sequence of a bi-polar sunspot around solar minimum.  The wedge and filter were recently purchased from Astro-Fest.  The continuum filter (540nm, 10nm pass) was recommended, and I have to say it is very effective on this old-style refractor,  Aberrations are reduced and granulation enhanced. Hope to make more of this setup
