Orion 4.00-Inch ID E-Series Black Polymer Safety Film Solar Filter for Orion ShortTube 80 Refractor & FunScope TableTop Reflector Telescopes

Bought one of these in 2014 in the hopes I could use it on my Canon 100-400mm zoom lens. Found it a snug fit when using felt stuck round the inside of the filter tube. It has been in use on and off to photograph the Sun every year. Very pleased with the results. Photo of the Sun showing Sunspot is cropped but quite clear.

Works like it is supposed too and is easy to fit

received a excellent service would recommend and purchase again

Spot on, fits my scop well.

El precio es adecuado a la calidad del producto, me funcionó muy bien para lo que lo buscaba, el material no es el mejor pero con el cuidado adecuado es muy duradero, además es ligero y práctico.
