Baader BDSF Digital Solar Filter 180 mm

The Baader BDSF Digital Solar Filter 180 mm Is a large format solar filter for digital photography of the sun with telescopes or telephoto lenses of approximately 180-210 mm outer diameter. This filter is ideal for serious astrophotographers who want to achieve maximum sharpness and contrast without risk to their equipment.

The BDSF filter film is based on Baader's AstroSolar technology, with a lower transmission specifically tailored to digital sensors. This gives you realistic, neutrally colored solar images with high dynamic range and minimal post-processing.

The sturdy aluminum filter holder features soft clamping feet and ensures a secure fit without pressure on the lens. The flat-tensioned film delivers stress-free, optically clean performance - essential at high resolution and long focal lengths.
