Take a look at the transmission diagram on the Amazon or the Astromania website (scroll through the images Contains about 375nm of UV reduction, but about 90% of the CaK line (393) is let through, so I purchased this filter for astrophotography with the Solar CaK line. The majority of UV-emitting Filters that block the IR line will completely block the CaK line. A UV pass filter is necessary when you want to photograph in the UV spectrum.
Selected User Reviews For Astromania 1.25" IR/UV Blocking Filter - Keeps Your Planetary Images Sharp
I had to laugh when I saw 1 "I cannot see a difference in the product," wrote a star reviewer. Infrared and ultraviolet light are blocked by this filter. It is neither visible to humans nor can it be heard. As a consequence, the reviewer was complaining that he couldn't clearly see that the filter blocked something he couldn't see in the first place. Complaining that you can't hear a dog whistle is like complaining that you can't hear the bird. In this case, this filter may be used with a digital camera that does not already Sensors that are sensitive to infrared light are available for digital cameras. If you do not apply the filter, red will appear too red, and your targets will be distorted.
This site has a lot of positive reviews, which I find hard to believe. There's a possibility that I got a lemon. I tried a few different lenses, but none of them produced any results. As a matter of fact, I was actually beginning to believe that it had fallen out somehow, since I observed no noticeable difference between Jupiter and any other target. In my further viewing, I actually found that it in fact decreased the accuracy of the It was one of the fastest returns I've ever made. Arrived at 915pm when I was looking at the apartment. A simple "wow" was all I could think! I couldn't have timed it better. The return was processed by 945pm after the return package was repackaged. Since it's only a 25 dollar filter, we shouldn't expect much from it. It was disappointing, but at least there was I'd like to point out how positive the reviews are. I can tell it's a transparent piece of glass just by looking at it. I could have been given a defective one, who knows. That is a shame because I honestly believed I had found a Diamond in the rough after reading all those reviews. However, it was not to be.
The filter was used to take photos of Mars, Jupiter, and Saturn this year. I am happy with how it worked and the quality is great. The cable was connected without issue to my astro camera. This is a good.
This appears to be a very good product. I use it with my Herschel wedge telescope for white light imaging and for observing the sun in the morning. As far as I can tell, the filter works as intended.
A quality filter like this is available. The construction is nice and it fits into my eyepieces and camera without any issues. In case you are looking for an IR cut filter, it would be my recommendation.
The filter looks good. At 700 nm, there is a very sharp cutoff I didn't test the UV side. As you can see from the transmission and absorption curves, as well as the apparent passband shifts at extreme angles, I think this is a dichroic.
An IR filter was needed for my finder scope, and this one fits the bill perfectly.
