Description
- Baader 1¼" Double Polarizing Filter - Perfect for observing moon or planets, or for solar observations with AstroSolar Safety Film ND 5.0.
- For 1¼" eyepieces, is inserted into the standard filter thread. One part of the filter cell is rotatable, so that you can adjust the brightness to the magnification of the eyepiece.
- Both filters form a unit, to keep the filters perfectly aligned to each other – this double filter cannot be seperated into to single filters. This way, the filter delivers high-contrast views even at high magnifications. Polarizing filters offer the highest flexibility; if you are looking for superior image quality, you should use regular Neutral Density Filter, where there are less glass surfaces in the light path.
- Please note: Polarizing filters (and all other eyepiece filters) may never be used without an approriate solar filter (Astrosolar front filter, Herschel Wedge).
