Astromania 1.25" IR/UV Blocking Filter - Keeps Your Planetary Images Sharp

An affordable, value conscious, performance filter. It performs quite satisfactorily in combination with my astronomy optical train. It has to be matched sizewize to your camera so you don't have vignette issues. Yes, there are really expensive filters available, but unless your entire optical train is at that level, the price may not be worth it.

Filter arrived, well packaged, and is as described.

Nice filter! Getting better pics

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... 😁😁😁

Works very well having extra is needed.

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.

Seems to work well. Screws on nicely.

I’ve used other filters like this in the past and this one performs just as good. Stars are sharper and the overall image has a neutral color. Would recommend.

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.
