“The filter is really excellent and my Mars images improved a lot.” Eric
“In combination with the Baader Contrast-Booster filter, a great tool for planetary photography.” Michael
“On the one hand, I use this filter as a focusing filter when I want to use the very dark H-alpha filter and on the other hand, I use it for shots in the Visible range with my full-spectrum modified Sony A6300. Otherwise, the IR component would lead to slight red halos around the stars, since long-wave light requires a different focus. The UV / IR filter blocks these unwanted wavelengths and thus ensures a sharper image. Other UV / IR filters from the photo range have a significantly less steep drop in the red range and thus a lower permeability for the H-alpha band. In addition, they can have a different glass thickness than the Baader filters and are then unsuitable for focusing instead of the H-alpha filter.” Alexander
