SVBONY SV183 IR Pass 685nm Filter
Infrared filters, sometimes called IR pass filters. This is a good item for the moon and other planet, because sometimes the moon is too bright to see the details.
Compatibility:
Fit all 2 inches eyepieces with botton filter threads. And also fit some barlow lens with filter threads.
When should I use an IR pass filters?
Since CCD and CMOS sensors are sensitive to IR light, imaging in the infrared will improve your results. Reduce reasonable level brightness and see more Planetary details by darken the twilight sky background at dawn or dusk.
In addition to astronomical uses, the IR-Pass filter can be used for nature photography in the Near-IR, revealing stunning differences in plants, sky, and clouds (requires use of a camera that is sensitive to IR above 670nm, such as a modified DSLR or webcam).

- SV183 IR Pass 685nm filter; M48*0.75 thread; standard 2 inches can be connected with eyepieces or telescope cameras with the same thread to achieve the purpose of observation or shooting
- Telescope filter cell is made of lightweight; strong metal and is CNC machined; sand-blasted; black anodized; and then laser engraved
- The IR Pass filter blocks wavelengths below 670nm; reduce the effects of seeing when used in IR-LRGB imaging of the moon and planets
- Sufficient reduction of seeing effects; heightened contrast; the IR Pass filter can be a great asset for daylight IR-imaging with a digital camera lessening seeing effects and improving contrast when utilized for lunar and planetary imaging
- The IR Pass 685nm filter is made with high-end glass that has been multi-coated with an ion-assisted deposition technology to ensure scratch resistance and stability on the central wavelength
- The filter can darkens the twilight sky background; allowing images of moon and planets to be taken at dawn or dusk
- The IR Pass 685nm filter is presented in a quality filter box; protects the product from damage in transit and facilitates storage when not in use
