Does the 1,25" DS-SContinuum filter substitutes the 2" SContinuum filter of the Hersschel Prism?
I am planning to buy the double stacked version, do I still need an additional UV/IR block filter with the current version of these filters?
Do you plan to sell a 2" version?

Double Stacked Solar Continuum Filter - For Visual and Photographic Observations of the Sun
Ensures highest contrast in the photosphere of the sun. The filter works as a monochrometer - suppressing the effects of the atmospheric turbulence and results in images that are significantly sharper. Owners of SCTs and refractors will benefit as red and blue wavelengths are completely excluded, with the transmission area peaking at 535nm where telescope optics are sharpest and free from chromatic aberrations.
Important Information for Solar Observing
The Solar Continuum Filter may be used for purely VISUAL observation ONLY in conjunction with the Baader Herschel Prism or with the Baader AstroSolar® Safety Film 5.0. The supplied AstroSolar® Photo Film 3.8 is for photographic use only and MUST NOT be used for visual observations.
The combination of AstroSolar® Photo Film 3.8 and Solar Continuum filter is used exclusively for photography of the sun at high magnifications. This combination is highly apt to capture the finest solar surface detail and granulation at extremely high magnification while enabling ultra-short exposure (measured in milliseconds) in order to freeze atmospheric turbulence.
