Baader ASSF 65 mm Spotter AstroSolar Filter
Fits 70-85 mm OD & 96-111 mm ID
Telescopes, Spotting Scopes & Camera LensesBaader ASSF AstroSolar Solar Filters are designed to fit a wide variety of spotting scopes, smaller refractor telescopes using magnifications of up to 120X, and camera lenses. The Baader AstroSolar Safety Film (ND 5.0) is mounted at the factory onto a clear white, IR-rejecting plastic ring that has a similar thermal expansion coefficient to minimize thermal stress on the film. Raised edges along the inner and outer circumference protect the solar film from contact with any sharp metal edges. This ring is then attached to the aluminum front frame of the filter, providing a very rigid and stable filter cell.Each Baader AstroSolar Filter comes with two different lengths of centering bolts (the 65 mm comes with 13 mm & 24 mm) to give you leeway for mounting on your telescope, spotting scope, or camera lens. These centering bolts, with their non-slip rubber facing, are used to make contact along the outside, or if feasible, the inside diameter of your instrument. Non-rotating sliding aluminum fasteners hold the centering bolts. Additional Phillips head screws are integrated into the sliding fasteners so that, if you wish, you can use a screwdriver to fasten the centering bolts firmly into place. An indexing system is in place to allow repeatable and fast adjustments of the filter cell if you use it on more than one instrument.You will also receive three security straps which allows you to secure the position of the filter with Velcro-adhesive pads. This extra security feature ensures that the filter will stay put even in windy conditions.Baader ASSF 65 mm Solar Filter SpecificationsBest for Apertures: 55 mm – 75 mmFilter Aperture: 65 mm or 2.56Outer Cell Diameter: 125 mmNet Weight: 77 grams or 2.7 ouncesID Clamping Range with 13 mm Bolt: 96 mm – 111 mmOD Clamping Range with 13 mm Bolt: 70 mm – 85 mm
