Feature

●Der ZWO 852-nm-IR-Pass-Filter ist für infrarotempfindliche Kameras wie die ASI224MC gemacht und ermöglicht spektakuläre Aufnahmen.
●IR-Passfilter - Interferenzfilter mit 1,25" (31,7mm) Filtergewinde für Teleskope
●Sperrt das gesamte sichtbare Licht aus, der Filter öffnet erst kurz vor 800 nm ( s. Bild mit Hand)
●Der Filter ermöglicht spannende Aufnahmen, wie zum Beispiel die Adern durch die Handfläche (Abbildung links - durch die Kamera ASI224MC, IR-Passfilter und Objektiv)
●Der Filter ist interessant für Mond-, Planeten- und Sonnenfotografie.


Description

ZWO 1.25" 850 nm IR Pass Filter for Infrared Photography
The IR pass filter is suitable for cameras which are sensitive for infrared light. Cameras with built-in IR block filter cannot be used with this filter. Examples for IR-sensitive cameras are ASI224MC or ASI185MC. But DSLR cameras with removed IR protection filter and CCD cameras are suitable for infrared photography.
Functionality and features:
The IR pass filter blocks all the visible light. Usually, the range goes up to about 700 nm, that is deep red light. The transmission curve of the ZWO filter rises steeply shortly before 800 nm and reaches maximum transmission at 860 nm
This extreme filtering allows exciting applications like:
- Long-distance photography at daytime - due to reduced diffraction, mist becomes more transparent, as the skin in the image of the Hand
- Planetary photography - removing the shorter wavelengths has a calming effect on the seeing. Especially Venus and Mars images become spectacular.
- Experiments with deep sky photography - with suitable telescopes
