This filter reduces light intensity to a safe level for camera sensors, allowing you to take razor-sharp, high-contrast images of sunspots, faculae and the fine grain structure of the solar surface with short exposure times.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The BDSF (Baader Digital Solar Filter) is derived from Baader's famous <strong>AstroSolar Safety Film<\/strong>, but with a modified transmission perfectly matched to digital sensors. This prevents overexposure and preserves maximum detail in high resolution, with no color cast. The result is neutrally colored sun images with a flat, optically clean surface that causes no additional distortion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>aluminum filter holder<\/strong> is robustly built and equipped with soft clamping feet that adjust to the diameter of your telescope or telephoto lens. The 100 mm filter aperture is suitable for telescopes or lenses with a <strong>outer diameter between approx. 100 and 130 mm<\/strong> (depending on model variant). The holder clamps securely without pressure on the tube or lens, preserving optical performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thanks to its light weight and stable construction, this solar filter is ideal for astrophotographers working with <strong>DSLRs, system cameras or planetary cameras<\/strong>. The flat film and neutral image make this filter particularly suitable for precision work, even at high magnifications or in combination with solar tracking systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Observation goals<\/strong><br>The Baader BDSF 100 mm is designed for <strong>digital solar photography<\/strong>. Not intended for visual observation. Always mount the filter in front of the objective lens and check that the surface is undamaged before each use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What you can photograph with it:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sunspots and penumbra in sharp detail<\/li>\n\n\n\n<li>Brightness differences and faculae at the solar edge<\/li>\n\n\n\n<li>The structure of granules on the solar surface<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Specifications<\/strong><br>Type: Solar filter for digital photography<br>Series: Baader BDSF (Digital Solar Filter)<br>Optical material: AstroSolar Safety Film (digital transmission)<br>Filter holder: Aluminum with soft clamping feet<br>Effective filter aperture: 100 mm<br>Suitable for lens\/telescope diameter: approx. 100-130 mm<br>Color rendering: Neutral white<br>Use: For photography\/video only (not visual)<br>Safety standard: CE certified according to ISO 12312-2<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Suitable for<\/strong><br>Solar Photography: \u2714<br>Visual observation: \u2717<br>Planetary use: \u2717<br>Telescope lenses, telephoto lenses, spotting scopes: \u2714<\/p>","protected":false},"excerpt":{"rendered":"<p data-start=\"49\" data-end=\"197\">Baader BDSF Digital Solar Filter 120 mm comes with precision filter in aluminum holder, protective cap and storage box.<\/p>","protected":false},"featured_media":30137,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[541],"product_cat":[56,469,587,588],"product_tag":[],"class_list":["post-30135","product","type-product","status-publish","has-post-thumbnail","product_brand-baader","product_cat-telescoop-accessoires","product_cat-astro-fotografie","product_cat-camera-accessoires","product_cat-filters","product_shipping_class-licht","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"bundled_by":[],"bundle_stock_status":"instock","bundle_stock_quantity":null,"bundle_virtual":false,"bundle_layout":"","bundle_add_to_cart_form_location":"","bundle_editable_in_cart":false,"bundle_sold_individually_context":"","bundle_item_grouping":"","bundle_min_size":"","bundle_max_size":"","bundle_price":[],"bundled_items":[],"bundle_sell_ids":[],"acf":[],"jetpack_sharing_enabled":true,"jetpack-related-posts":[{"id":104875,"url":"https:\/\/www.telescoop.nl\/en\/levenhuk-labzz-t3\/","url_meta":{"origin":30135,"position":0},"title":"Levenhuk LabZZ T3 - 60\/700 Refractor","author":"Abdullah Ibrar","date":"24-03-2026","format":false,"excerpt":"Levenhuk LabZZ T3 - 60\/700 Refractor comes with 4mm eyepiece, 12.5mm eyepiece, 1.5x eyepiece, 3x Barlow lens, 5x optical viewfinder, zenith mirror and aluminum tripod with accessory tray.","rel":"","context":"Similar post","block_context":{"text":"Similar post","link":""},"img":{"alt_text":"Levenhuk LabZZ T3 - 60\/700 Refractor aluminium statief met accessoirebak","src":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/03\/Levenhuk-LabZZ-T3-60700-Refractor-1.jpg?resize=350%2C200&ssl=1","width":350,"height":200},"classes":[]},{"id":105543,"url":"https:\/\/www.telescoop.nl\/en\/levenhuk-skyline-travel-70\/","url_meta":{"origin":30135,"position":1},"title":"Levenhuk Skyline Travel 70 - 70\/400 Refractor","author":"Abdullah Ibrar","date":"03-04-2026","format":false,"excerpt":"The Levenhuk Skyline Travel 70 \u2013 70\/400 Refractor comes with 10mm and 20mm eyepieces, a 3x Barlow lens, a 5x24 finderscope, a diagonal prism, an aluminum tripod, and a backpack.
