2" polarizing filter for use alone or combined with another polarizer or Herschel wedge for brightness control. Never use without proper solar filtering
DESCRIPTION
The Baader 2" Single Polarizing Filter allows smooth brightness adjustment when paired with a second polarizing filter or a Herschel wedge, which already polarizes light. It is ideal for observing the Moon, planets, or the Sun in combination with AstroSolar ND 5.0 safety film. You can pair a 2" and a 1.25" filter (e.g., in an eyepiece and adapter) and rotate them to control brightness based on magnification. The filter mounts into 2" eyepiece threads and can be used after a Baader Herschel wedge. It enhances contrast in planetary observation. It is a neutral density-type filter with full-spectrum transmission. Warning: it must never be used alone for solar observation — always with proper front-end solar filtration (Herschel wedge or AstroSolar film). For integrated brightness control, Baader also offers dual polarizing filters (#2408340 in 1.25" or #2408344 in 2").
