These filters, when used in pairs, heighten contrast and object visibility.

They are compatible with Explore Scientific screw filters with a 1.25-inch / 31.7mm diameter.

Don't skimp on the tripod!

I had my new binoculars setup next to my buddy with his 10' Dobsonian, he expressed his surprise at the amazing views. We could go toe to toe no problem!

Amazing Optics!

I use them for tripod mounted wildlife viewing, I know, serious overkill. I have to perfect high ground location. I've spotted deer a mile away with amazing detail.
