Glass Solar Filter ST450G, Spectrum Telescope. Condition is Used. Shipped with USPS First Class Package.
Used it for 1 day during the Aug 2017 US solar eclipse. Great condition and worked well with a Celestron telescope and DSLR camera. Got some pretty good amateur pictures of the eclipse.
Glass filter encased in an aluminum housing. 3 plastic thumb screws.
I do not know it's ND factor. For more information see supplier link below.
FYI. I see 1 small imperfection on the outer side amost exactly in the center. It doesn't show in the pictures and it's hard to see holding it in your hand. Very very tiny. It didn't effect my pictures. Probably made during assembly.
