Baader variable Polarisation Filter 2" with continous brightness adjustment

Name: Baader variable Polarisation Filter 2" with continous brightness adjustment
Brand: Baader
SKU: BA2408344
Price: 116 EUR

Ideal for lunar and planetary observation - the filter reduces brightness continously.

The polarising filter is screwed into the 2" filter thread of the eyepiece or the adapter.

M48 2" filter thread - fits directly to eyepieces or adapters

By turning of one of the filters, a continous reduction of brightness is possible. Thus the filter effect can be matched to telescope and magnification.

The 2" polarising filter from Baader allwos for continous brigthness adjustment. The filter consists of two polarising filters of which one is mounted rotatable. By rotating, transmission is changed.

The effect of the Baader 2" polarising filter:The filter reduces brightness to 1% to 40% and improves the visibility of fine details of moon and planets. The special advange is that you can match the filter effect to your individual needs.

The application of the variable polarising filter for solar observation: Especially with front filters, which transmit a fixed part of the light, the use makes sense. At low magnifications, the disc of the sun may appear to bright, so a stronger filtering is sensible. At higher magnifications, a weaker filtering is recommended.

ATTENTION! The polarising filter does not replace an effective and safe front solar filter!

The variable polarising filter does not make sense together with Herschel prisms, as they already produce polarised light. For this reason, we recommend a single polarising filter from Baader.
