Baader Variable Polarising Filter 1.25"
Baader 1.25" variable polarising filter for lunar and planetary viewing, also suitable for solar observation with additional AstroSolar ND 5.0 filter.
Baader Variable Polarising Filter 1.25"
Description:
The Baader variable polarising filter in 1.25" format is designed to enhance visual comfort during lunar, planetary, and solar observations (with additional filtering). It enables smooth brightness adjustment by rotating one of the polarising elements, depending on the magnification and light conditions.
This system is a fixed, double polarising unit that cannot be separated, ensuring perfect alignment and eliminating internal reflections. The filter screws into any 1.25" standard-threaded eyepiece.
Its flat-parallel optical surfaces and high-quality coatings guarantee a sharp and high-contrast image even at high magnifications. For purely neutral light transmission, simple neutral density filters remain the best alternative for imaging.
Important: for solar observation, this filter must be used together with a certified safety filter such as AstroSolar ND 5.0 film or a Herschel wedge.
Technical specifications:
– Size: 1.25" (31.75 mm)
– Type: double variable polarising filter
– Adjustment: manual rotation
– Threading: standard 1.25" eyepiece
– Construction: fixed dual unit, flat-parallel
– Coating: anti-reflection multi-coating
– Total height: 15 mm
– Filter thickness: 2 mm
– Light transmission: variable
– Use: lunar, planetary, solar (with ND filter)
Additional information:
This filter is delivered as a one-piece assembly and cannot be disassembled into separate units, ensuring optimal optical performance.
