I didn't know that our human eyes were somewhat and somehow sensitive to Infra-Red light until I read an article online about blocking IR when doing astrophotography. So I bought a IR blocker to try visually and Wow I am amazed at the increase in the sharpness of focus that I get..!! I am now using the IR blocker with all my eyepieces..!! I will have to buy another one for my other eyepieces..!! It works for me... 😁😁😁

Muy útil para disminuir la aberración cromática en refractores. Con la ayuda de este filtro se puede observar a Jupiter y a Saturno sin halo. Para el caso de la luna no sirve tanto y le da una coloración amarillenta.

Had to laugh at the 1-star reviewer who "couldn't see a difference."This filter blocks Infrared and Ultraviolet light. Neither of which can be seen by humans. So the reviewer was complaining that he couldn't see the filter blocking out something he can't see anyhow... It's like complaining that you can't hear a dog whistle.This filter is intended for use with a digital camera that does not have a built-in filter. Digital sensors can be very sensitive to infrared light. Without the filter, reds will appear too red and skew the color of your targets.
