Unfortunately, there have also been complaints about reflections occurring with this combination. With this filter, you can counteract this problem. It produces a virtually colour-neutral image without the blue and red halo that so disturbingly reduces image contrast in cheap refractors.\u003c\/p\u003e\n\u003cp\u003eThe Fringekiller blocks about a third of the blue light. The transmission in red and green light is 100%. The resulting loss of light over the entire spectrum is only about 12%.\u003c\/p\u003e\n\u003cp\u003eThe semi-apo filter blocks more than 25% in blue and red light. The proportion is lower in green, but about 30% of light is lost across the entire spectrum. But the colours are once again neutral, except for a slight green tint. The light reducing effect of the semi-apo filter is about half a stop.\u003c\/p\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; line-height: 1.4;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\" style=\"padding: 8px 4px 4px; font-weight: bold; font-size: 0.95em; border-bottom: 1px solid #333; color: #333;\"\u003eCapacity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background: #f5f5f5;\"\u003e\n\u003ctd style=\"padding: 4px 6px; width: 50%; font-size: 0.9em; color: #333; border-bottom: 1px solid #e8e8e8;\"\u003eFrame\u003c\/td\u003e\n\u003ctd style=\"padding: 4px 6px; font-size: 0.9em; color: #333; border-bottom: 1px solid #e8e8e8;\"\u003e2\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Nimax","offers":[{"title":"Default Title","offer_id":49273132122267,"sku":"10902","price":159.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0575\/5260\/1243\/files\/Baader-Filters-2-Semi-APO-filter2.webp?v=1786634359","url":"https:\/\/astronoscope.com\/products\/telescope-colour-polarizing-filter-baader-semi-apo-filter-2","provider":"Astronoscope","version":"1.0","type":"link"}
