The perfect mounting cell for eclipse photographers

AstroSolar film is the standard for white light solar filters. This mounting cell has two great advantages for eclipse photographers. The wide flange shades your camera avoiding overheating. The external 3 rubber bumper attachment is easy to remove and replace quickly without disturbing your aim. This is a great advantage for totality in a total solar eclipse. Highly recommended
