Users of SCTs and achromatic refractors will find it particularly beneficial, as it completely excludes the red and blue wavelengths, and centers on the peak visual wavelengths where the telescope optics are sharpest and free from chromatic aberrations. For digital imaging, we also recommend the Continuum filter be combined with our UV\/IR Cut Filter (to completely cut the defocused far infrared wavelengths).\u003c\/p\u003e\u003cp\u003eThe Solar Continuum filter also makes the perfect star test filter.

Available in sizes from 80mm to 280mm, this filter maintains its optical figure across a wide temperature range, from -30°C to +50°C. Each filter includes two sets of adjustable centering pins (10mm and 20mm diameter) and three safety straps, ensuring a secure fit to your telescope's tube or dew shield for uncompromising safety and image sharpness.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eDiffraction-Limited Views: The Stress-Free OD 5.0 AstroSolar Film Cell\u003c\/h3\u003e\n\u003cp\u003eUnlike DIY or improperly mounted filters that stretch the film taut like a drumhead, Baader's ASTF filters mount the OD 5.0 AstroSolar film with zero tension. This proprietary, temperature-compensated cell allows the film to \"float,\" preserving its sub-micron surface accuracy and acting as a high-precision optical window. The result is the ability to resolve fine solar details like granulation and sunspot penumbrae, which are often blurred into mush by the microscopic distortions induced by a stretched film.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eUniversal Mounting with 10mm \u0026amp; 20mm Centering Pins\u003c\/h3\u003e\n\u003cp\u003eEach ASTF filter ensures a secure, centered fit on a wide range of telescope tubes and dew shields.

In reality, the slight waves and wrinkles visible in the AstroSolar film are proof that it is mounted correctly and free from tension. When film is stretched to look flat, it introduces astigmatism and other aberrations that degrade the image at the focal plane. The Baader ASTF filter cell is purpose-built to maintain this crucial, stress-free state, delivering image quality that stretched, DIY filters cannot match at high magnification.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs the Baader AstroSolar OD 5.0 filter safe for looking at the Sun?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003e\u003cstrong\u003eAbsolutely.\u003c\/strong\u003e The \"OD 5.0\" designation means the filter has an Optical Density of 5.0, which blocks 99.999% of all sunlight, including harmful UV and IR radiation.

Baader's design intentionally mounts the AstroSolar film without any tension. This stress-free state is essential to preserve the film's diffraction-limited optical quality.

imaging. Its unique temperature-compensated cell maintains diffraction-limited optical quality from -30°C to +50°C, allowing you to capture sharp solar details without thermal drift. \u003cstrong\u003eThis filter is designed exclusively for photographic and digital imaging; it is NOT safe for direct visual observation of the Sun under any circumstances.\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eOptical Density 3.8: Engineered for High-Speed Solar Imaging\u003c\/h3\u003e\n\u003cp\u003eThe core of this filter is Baader's AstroSolar FOTO Film, which has an optical density (OD) of 3.8. This transmits more light than visually-safe OD 5.0 films, enabling extremely short exposure times. For solar imagers using digital video or lucky imaging techniques, this is a critical advantage for \"freezing\" the atmospheric turbulence and capturing moments of perfect seeing, revealing fine granulation and sunspot details that would otherwise be blurred.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eTemperature-Compensated Cell: Maintaining Optical Flatness from -30°C to +50°C\u003c\/h3\u003e\n\u003cp\u003eTo perform like a high-precision optical window, AstroSolar film must be mounted completely free of tension. The Baader Digital Solar Filter achieves this with a sophisticated, temperature-compensating cell. The film is bonded to an injection-molded ring that shares its thermal expansion coefficient, and this entire assembly \"floats\" within the main aluminum frame. This design ensures the film remains optically flat and stress-free across a -30°C to +50°C temperature range, preventing image degradation caused by thermal contraction or expansion.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSecure 3-Point Mounting System with Adjustable Pins \u0026amp; Safety Straps\u003c\/h3\u003e\n\u003cp\u003eA solar filter's security is paramount.

Unlike many solar filters that produce an artificially colored orange or yellow image, AstroSolar® film is engineered for a neutral \"ClearWhite\" color balance.

The result is a reduction in solar intensity by a factor of more than 100,000, blocking 99.999% of incoming sunlight and making it completely safe for visual use. The ClearWhite coating ensures the Sun appears in its natural color, free from the artificial orange or blue tints introduced by some other filter types, allowing you to see sunspots, faculae, and granulation in neutral tones.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSecure Mounting with 3 Adjustable Centering Bolts and Safety Straps\u003c\/h3\u003e\n\u003cp\u003eA solar filter is only safe if it stays securely attached to your instrument.

80mm-class telescopes up to the ASTF 280 for 280mm (11-inch) instruments. Their renowned AstroSolar® film features an Optical Density of 5.1, safe for direct visual observation through the telescope and for solar photography, while rendering high-contrast, neutral white-light images of sunspots, granulation, faculae, and the partial phases of solar eclipses.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eAstroSolar OD 5.1 Film: Diffraction-Limited White-Light Views\u003c\/h3\u003e\n\u003cp\u003eAt the heart of every ASTF filter is Baader's AstroSolar® Safety Film, which achieves the optical quality of a high-precision, plane-parallel glass filter without the associated cost. It blocks harmful ultraviolet and infrared radiation, and unlike many lesser filters that produce an orange-tinted, low-contrast image, it delivers a \"ClearWhite\" view, showing the Sun in its natural color for objective analysis and photography.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eTemperature-Compensated Cell for Consistent Optical Integrity\u003c\/h3\u003e\n\u003cp\u003eTo maintain its diffraction-limited performance, AstroSolar® film must remain completely free of tension. Every ASTF filter features an advanced, temperature-compensating cell that allows the film to \"float.\" The film is mounted on an injection-molded ring with the same thermal expansion properties, which is then held within the aluminum frame by a separate glass-fiber-reinforced ring. This design ensures the film never stretches or shrinks due to temperature changes, preserving its exquisite image quality from a frigid -30°C to a scorching +50°C.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eASTF vs. DIY Filters: The Critical Role of a Tension-Free Mount\u003c\/h3\u003e\n\u003cp\u003eMany homemade solar filters stretch the film taut like a drum skin in an attempt to make it look flat like glass. This process completely destroys the film's optical properties, resulting in blurry views unsuitable for high magnification. A correctly mounted AstroSolar® filter will exhibit slight waves; this is a sign that the film is tension-free and ready to perform as a precision optical window. The professional construction of the ASTF cell removes the guesswork and risk, guaranteeing optimal performance in every size.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSecure and Adaptable Mounting System for Telescopes\u003c\/h3\u003e\n\u003cp\u003eEach ASTF filter is equipped with a robust and versatile mounting system to ensure a safe, secure fit on your telescope's tube or dew shield. Adjustable centering bolts slide into the aluminum frame to center and clamp the filter on your instrument; the ASTF 120 and ASTF 200, for example, come with two sets of three 38mm-long bolts in 10mm and 20mm diameter, plus rubber plugs for unused openings. For added peace of mind, included safety straps with adhesive pads anchor the filter to your telescope, preventing it from being accidentally dislodged by wind or a sudden bump.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhy does the film in my ASTF filter look wrinkled?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThis is intentional and a sign of correct mounting.

7.5nm 1.25″ Filter is a specialized solar continuum filter, isolating a narrow 7.5nm bandpass centered at 540nm to dramatically increase the contrast of solar granulation, faculae, and sunspot details. As part of Player One's E-series, this 1.25\" filter uses a high-quality glass substrate and advanced multi-layer coatings optimized for modern CMOS and CCD sensors, ensuring professional results in high-resolution solar imaging.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eHigh-Contrast Photosphere Imaging at 540nm with a 7.5nm Bandpass\u003c\/h3\u003e\n\u003cp\u003eBy targeting the 540nm wavelength, this filter operates near the peak of the Sun's light emission, delivering a bright, detailed signal to your camera.
