Product Description
Designed to fit snugly over the aperture of your telescope, these optical glass filters block 99.999% of incoming sunlight, allowing you to safely observe sunspots and solar granulation in the Sun's photosphere. The Sun appears in a natural, whitish color. The glass elements are machine-polished and triple-coated with nickel-chromium stainless steel for a scratch-resistant surface. Each filter has three nylon thumbscrews to ensure a snug fit to the front of your telescope or binocular. The thumbscrews complement the press-fit foam lining inside the filter's durable aluminum cell to accommodate diameters up to ¼" smaller than the nominal size. A tight press fit is still required for safe solar viewing. Lifetime limited warranty.

Good solar filter
By Zen Ko
I bought this for my 10" Meade LX200. The fit was loose so I had to use the supplied extra padding. The fitting was still loose so I contacted Orion who told me to buy some extra padding from a hardware store. Now the fitting is fine although I am careful not to point the telescope downward in case the filter falls off (I suspect it will not survive a 4ft fall). I chose a glass filter because I read several reviews saying that they were superior to mylar. Apart from the minor inconvenience of the padding, I would definitley recommend this filter.
