These type of filters have been LEGISLATED against here in Oz. Have never seen a sun filter from Saxon yet, and don't want to! These types of filters were meant to be used in conjunction with an Herschel wedge where only 5% of the incident light is reflected to the eyepiece, the eyepiece is fitted with a No4 Density sun filter to bring that 5% down to 0.01% which is safe for viewing. The other 90% passes through the prism and out through a hole in the prism cover. If you see one, stomp on it, smash it with a 5kg sledge hammer, and ensure that al that left is glass powder!
