here we go with the best available equipment to observe the suns white light, a 1/10 wave APM Herschelwedge with a photovisual filterset from the best filter maker , BW-Schneider Kreuznach in Germany ( high quality polished Schottglas). The Baader Astrosolar is already of superb visual quality, but a highest quality polished BK 7 glas filter like our APM Glasfilters with 1/10 wavefront p.t.v. transmission quality ( rather expensive ) and the herschelwedges showing the diffrent colors of the umbra and penumbra but also the granulation with clearly visible higher resolution
The 1.25" wedge cost US $ 139, the 2" Wedge cost US $ 279. A Filterset cost US $ 72 additional, plus shipping
