In addition to the structures known from white light, such as sunspots, you can see the chromospheric network distributed over the entire surface of the sun, which precedes the formation of sunspots, as well as cells of supergranulation and Ellerman Bombs.\u003c\/p\u003e\n\u003cp\u003eThe emission line of calcium at 394 nm is already in the near UV. That's why observing the sun at this wavelength is only possible with a camera! Never use this filter for visual observations, as our eye is blind for the harmful UV-radiation, but can be damaged by it.\u003c\/p\u003e\n\u003cp\u003eThis filter delivers the best results when used with a monochrome camera (which is more sensitive in this part of the spectrum than a colour camera) and mirror telescopes (because especially refractors with fast f\/ratios are not optimized for best sharpness in this part of the spectrum). Nevertheless, many lens telescopes still work fine for calcium observations; unmodified DSLRs may need extremely long exposure times.\u003c\/p\u003e\n\u003cp\u003eAll calcium-filters require an additional solar filter in front of them. Part of the Baader GEN-II is a sheet of AstroSolar Photo Film OD 3.8, 20x30 cm (#2459278) to build a solar filter by yourself, so that you can start observing without purchasing any other filters. Of course, you can also use one of the BDSF: Baader Digital Solar Filter OD 3.8 (80mm - 280mm) which are already mounted in a filter cell. On suitable lens telescopes, you can also use a Herschel prism. That way, you can replace the integrated ND3-filter mounted behind the Herschel with a weaker filter to reach shorter exposure times. These filters are already in the scope of delivery of the Baader Safety CoolCeramic Herschel Prism 2\" Photographic (#2956510P) .\u003c\/p\u003e\n\u003cp\u003eThe calcium GEN-II replaces the older K-Line Filter 1¼\" (stacked) # 2458355. Thanks to modern manufacturing techniques, a single filter now achieves a better quality and narrower half-band width (FWHM) of only 5 nm instead of the previous 8 nm; stacking two filters is now no longer necessary. This also makes it possible to use the filter in standard filter wheels\/drawers; the low-profile filter mount is only 6 mm high when screwed in.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Baader Calcium GEN-II also offers all the advantages of the CMOS-optimized Baader filters:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIncreased contrast, matched for typical CMOS quantum efficiency and s\/n ratio\u003c\/li\u003e\n\u003cli\u003eReflex-Blocker™ coatings, for largest ever freedom from halos, even under most adverse conditions concerning aux-optics\u003c\/li\u003e\n\u003cli\u003eIdentical filter thickness to existing standards, with utmost care for parfocality\u003c\/li\u003e\n\u003cli\u003eBlackened edges all around, with filter-lead-side-indicator in the form of a black frontside outer rim, to additionally eliminate any reflection due to light falling onto the edge of a filter\u003c\/li\u003e\n\u003cli\u003eEach filter coated individually, with sealed coating edge (NOT cut out of a larger plate with coatings left exposed, read more)\u003c\/li\u003e\n\u003cli\u003eLife-Coat™: evermore hard coatings to enable a non-aging coating for life – even in a most adverse environment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg style=\"float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0267\/1172\/0013\/files\/02A-ED80-f7-5-Herschel-ND18-2961590A-01.jpg?v=1682191292\u0026amp;width=700\" alt=\"Baader Calcium GEN-II at ED 80\/600\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cem\u003eBaader Calcium GEN-II at ED 80\/600\u003c\/em\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cspan\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0267\/1172\/0013\/files\/02A-Vixen-80-f11-Herschel-ND18-2961590A-02.jpg?v=1682191320\u0026amp;width=700\" alt=\"Baader Calcium GEN-II at 80\/910 Fraunhofer\"\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cem\u003eBaader Calcium GEN-II at 80\/910 Fraunhofer\u003c\/em\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cp\u003eTo use the 1¼\"-filter at cameras with 2\"-nosepiece, you can use either use a filter drawer like the Baader UFC System or a filter wheel.
