- ZWO IR-Pass Filter passes IR light and blocks visible light most sensitive to poor seeing
- Results in improved images of planets or Moon in less-than-ideal conditions
- Can be used to image planets during daylight
- Mounted in standard threaded 1.25" cell
- Comes with protective plastic case
The ZWO IR-Pass Filter passes infrared light with a wavelength of more than 850nm while removing the parts of the visible spectrum affected by poor atmospheric seeing. When you image the planets or Moon with a monochrome or color CCD or CMOS astronomy camera and the ZWO 850nm IR-Pass filter, you get improved results when seeing conditions are less than ideal or when the object is near the horizon. You can also use this IR-pass filter to image planets during daylight because it darkens the background sky.
This filter is not suitable for visual observation.
The ZWO 850nm IR-Pass filter is housed in a 1.25" cell and comes with a protective plastic case.
Manufacturer part # IR850NM1 (previously also known as # IRPASS).

Filter Cell Specifications
D = Filter Cell Diameter = 31.7 mm / 1.24 in
T = Total Filter Height = 7.5 mm / 0.29 in
C = Filter Cell Height (Excluding Male Thread) = 5 mm / 0.19 in
M = Male Thread Length = 2.5 mm / 0.09 in
F = USABLE Female Filter Thread Length = Not threaded, so you cannot stack additional filters
S = Glass Substrate Thickness = 1.8 mm / 0.07 in
CA = Clear Aperture = 26 mm / 1.02 in
