AstroSolar must be mounted entirely stress free in order to perform like a high precision planeoptical window. It sounds like a contradiction with traditional perception of quality, but AstroSolar must show slight ripples! Only when the film is being put under stress by an improper cell mount it performs just like any single side coated glass-filter made of untreated floatglass.
Ideal for most 50mm binoculars (Outer tube diameters from 55mm to 70mm)
Baader AstroSolar® Safety Film (OD 5.0), cell mounted and quality inspected by skilled members of our staff
Clear white IR-rejecting front ring with reinforcing raised edges along the outer and inner circumference,
designed to protect the solar filter material from contact with any sharp metal edge
3 injection molded centering-bolts with threaded brass inserts to center the filter-cell in front of the tube opening.
These bolts come in three different diameters, depending on the filter category (ASTF/ASSF/ASBF). Each bolt
features injection molded rubber grip-faces, shaped to easily slide onto any telescope tube securely
No tool mounting and adjustment of the centering bolts to fit a wide variety of mechanical tube diameters. Bolts made
to contact the outside or optional (if appropriate) the inside of the optical instrument tube
Non-rotating sliding fasteners made from aluminum that hold the centering bolts. These metal sliders are equipped
with a machined indicator to point towards the adjustment index· additional Phillips screws are integrated into the sliding fasteners, so that the centering bolts can be firmly fastened with a screw driver if preferred by the user
Index scale provided beside each adjustment slot adjacent to each sliding fastener, for fast and repeatable adjustment of the filter cell onto different telescope tubes
Black sliding washers supplied to securely cover the full length of the adjustment slots in the aluminum frame for blocking sunlight from passing trough the filter cell beside the filter area
Warning text printed onto the front side of each filter cell: Read the Instructions before use
All Filters feature clear white aluminum front frames, powder coated with IR (heat!) rejecting paint
