ZWO 1.25" IR Cut Filter # IRCUT1
|Brand||ZWO Astronomy Cameras|
Most telescopes, especially refractors, are not designed to focus infrared (IR) light to the same plane as visible light. For visual observing, this doesn't matter because the human eye cannot see infrared. But silicon CCD and CMOS sensors in astronomy cameras are very sensitive to IR, so out-of-focus IR light can result in blurry images and bloated stars. By cutting out IR, the ZWO IR-CUT filter results in much sharper images of astronomical objects.
The ZWO IR-Cut filter is also useful for solar work because it blocks infrared (and ultraviolet) light from reaching and damaging expensive H-alpha solar filters.
This IR-CUT filter comes with a protective plastic case and is housed in a 1.25"; cell with internal threads so you can stack filters together.

Quality filter at a reasonable pricePros: Cons: Comments:
Purchased this filter for my ASI-290 mini guide camera. Fit and finish is great and the filter provides the proper wavelength cut to improve the guide camera image. Highly recommend!Bottom Line: Would you recommend this item? Yes

If you are converting your old web cameras or photo scanners into telescopic eyepieces you will need this. Commonly the color looks washed out and the images can't seem to focus, this is because of infrared is not filtered out in the original devices. Infrared focuses at a different point that the other colors do with a corrected eyepiece. Your eye ignores it but CMOS and CCD sensors are very sensitive to it.Bottom Line: Would you recommend this item? Yes

Works Like a Charm!Pros: Cons: Comments:
I bought this filter especially for my newly-acquired ZWO ASI224MC camera to add clarity to my images. It easily attaches to the front of the camera and cuts not only IR but UV as well. It made a noticeable difference in my images, just allowing visible light to shine through. The ASI224MC does not come with an IR filter built-in so this filter is a must!Bottom Line: Would you recommend this item? Yes

Dark sky color correctionPros: Cons: Comments:
I was advised by zwo to use this filter to balance the extra green (rggb) found in the cmos sensor of the new and wonderful asi294mv pro camera. This filter worked as expected. The color out of the camera was beautiful.Bottom Line: Would you recommend this item? Yes

Good Quality, Great PricePros: Cons: Comments:
I bought this to use as an energy rejection filter ahead of my Daystar hydrogen-alpha filter, as noted in the description. Note that this strategy only works on refractor telescopes without any intervening optics between the objective and the UV/IR cut filter. I previously had a 2" Astronomik L doing this job, but then I modded my camera, so I moved the Astronomik to the camera and bought this. I noticed no degradation in the H-alpha image quality when I swapped the filters. I have no way to test the transmission spectrum, nor do I have any reason to doubt what they published. I imagine this would work just fine for imaging, but I have not tried it yet. I may do some tests after the eclipse. If so, I'll try to remember to update this reviewBottom Line: Would you recommend this item? Yes
TL;DR: Great price for a quality 2" UV/IR cut filter!
