Baader Planetarium 140mm AstroSolar BDSF 3.8 White-Light Digital Solar Filter for Telescopes

Make your solar imaging experience unparalleled with the Baader 140mm AstroSolar BDSF 3.8 White-Light Digital Solar Filter, specifically designed for telescopes. This advanced filter is the result of innovative developments following the release of the Baader Solar Filters OD 5.0 in spring 2015. It shares the same robust cell and mechanical specifications as the ASTF-Filter with Safety Film OD 5.0, but with a crucial difference: the inclusion of the AstroSolar PHOTO Film OD 3.8.The AstroSolar PHOTO Film OD 3.8 is a time-tested medium that significantly reduces exposure times, making it ideal for digital videography and the lucky imaging technique. By enabling such short exposure times, it effectively "freezes" atmospheric turbulences, providing you with crisp and clear images of solar phenomena. It's important to note that this filter is designed exclusively for digital imaging and is not suitable for direct solar observation.Unlike many ready-made filters that compromise image quality by stretching the material taut, the AstroSolar PHOTO Film OD 3.8 is meticulously mounted to remain entirely stress-free. This ensures that it performs like a high-precision plane optical window, maintaining its superior image quality even at high magnifications. The slight ripples in the AstroSolar film are a hallmark of its quality, indicating that it has not been subjected to damaging stress.The Baader ASTF/BDSF (AstroSolar Telescope Filter) series represents the pinn
