The Celestron UV IR is the ultimate UV and Infrared blocker, featuring hard Ionbeam coatings, and fine optically polished glass! The ideal filter for NexImage and CCD imaging. This filter has an extremely sharp cutoff at 690nm yet leaves all the visible red, including the important 656nm H-alpha emission line, preventing IR wavelengths from blurring fine detail in your digital images.
Special Features...
- Blocks infrared with a sharp cutoff of 690nm.
- Leaves all of the visible red (including 656nm H-Alpha emission line), which prevents IR wavelengths from blurring detail in images.
- Hard, scratch-resistant coatings protect the UV/IR Cut Filter.
- Freedom from ghost images (very low reflection multi-coating) enables pinpoint star images and fine planetary detail.
- Threads directly into any 1-1/4" diameter eyepiece and NexImage camera.
