Baader Digital Solar Filter with AstroSolar® PHOTO Film OD 3.8

Overview of Baader Solar Filter – The Standard

The Baader Digital Solar Filter with AstroSolar® PHOTO Film OD 3.8 is a specialized solar filter designed exclusively for digital imaging, not for visual observation. This filter allows for the shortest exposure times, making it ideal for high-resolution digital videography and the "lucky imaging" technique, which minimizes atmospheric turbulence.

Attention: Important Usage Information

AstroSolar PHOTO Film OD 3.8 is NOT intended for visual observation of the sun. Its specifications are tailored for digital solar imaging, providing an almost "frozen" view of atmospheric turbulences.

Key Features of Baader Digital Solar Filter

• High-Quality AstroSolar PHOTO Film: Mounted in a stress-free cell to maintain high optical quality, performing like a precision optical window.
• Temperature Compensated Cell: Ensures optical stability across temperatures, from -30°C to +50°C.
• Secure Mounting System: Equipped with injection-molded centering bolts and threaded brass inserts to fit various telescope diameters, with no tools required for adjustments.

Innovative Design for Optimal Performance

Unlike other filters that stretch the film, Baader Solar Filters mount the film without stress, preserving its optical integrity. This ensures the filter’s performance is akin to a high-quality glass filter, without the drawbacks of single-coated glass materials.

Additional Features of Baader Digital Solar Filter

• Durable Construction: Front ring designed with IR-rejecting properties and reinforced edges for protection.
• Sliding Fasteners: Non-rotating sliders hold centering bolts securely, featuring an index scale for quick adjustment.
• Safety Straps: Three Velcro-adhesive straps provide additional stability, ensuring the filter stays in place during usage.
