The special custom polishing operation Baader executes on all Narrowband passfilters makes the difference compared to standard commercially-made polished filter substrates. In the production process for Baader Narrowband CCD passfilters, consideration of eliminating annoying reflections present in other narrowband astro-filters was a key component. In order to succeed in assuring freedom from reflections, Baader's production process required careful design and testing of the coating stacks. This research work resulted in the fine, high-quality Narrowband 8.5 nm O-III CCD Filter offered here.\u003c\/p\u003e\u003ccenter style=\"box-sizing: border-box; margin: 0px; padding: 0px; font-family: \" open sans arial sans-serif rgb font-size:=\"\" background-color:=\"\"\u003e\u003ch1 style=\"box-sizing: border-box; margin: 0px 0px 0.7em; padding: 0px; font-size: 16px; font-weight: 400; font-family: Raleway, \" helvetica neue verdana arial sans-serif line-height: text-rendering: optimizelegibility text-transform: uppercase\u003e\u003c\/h1\u003e\u003c\/center\u003e","brand":"Baader Planetarium","offers":[{"title":"Default Title","offer_id":44013368049775,"sku":"FOIIIN-2","price":330.74,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/OIII_1-2__77884.jpg?v=1766551432"},{"product_id":"baader-1-25-uvir-filter","title":"Baader 1.25\" UVIR filter","description":"\u003ccenter style=\"margin: 15px 0px; padding: 0px; font-family: \" open sans sans-serif font-size:=\"\"\u003e\u003ch2 style=\"margin: 0px; padding: 0px; font-size: 16px;\"\u003eBaader UV - IR Cut L Filter - 1.25\" Mounted\u003c\/h2\u003e\u003c\/center\u003e\u003cp style=\"margin: 10px 0px; padding: 0px; font-family: \" open sans sans-serif justify font-size:=\"\" text-align:=\"\"\u003eThe Baader UV-IR Cut\/L Filter is a must for all digital imaging with DSLR cameras, CCD cameras, and modified webcams.

Here, different cloud bands, which show a steady change of details form similar to the cloud cover of Jupiter. Unfortunately, these clouds can not be seen in visible light, unlike Jupiter, meaning Venus appears completely structureless. However, by using a camera that is sensitive to inaccessible wavelengths unlike the eye, this cloud structure detail can be seen, in particular using ideal wavelengths in UV range between 320nm and 390nm.\u003c\/p\u003e\u003cp style=\"box-sizing: border-box; margin: 0px 0px 1.5em; padding: 0px; font-family: \" open sans sans-serif rgb color:=\"\" font-size:=\"\" background-color:=\"\"\u003eSince the early days of amateur astronomy, amateurs have been trying to work in this light. The difficulty is procuring a suitable filter to work precisely in this short wavelength region adequately. A sharp short-pass filter with high transmission is virtually impossible to produce. This also applies, surprisingly, to interference filters. While a theoretically ideal UV bandpass can be produced, there is inevitably at least one second passage window in the visible range. This is fatal because this undesirable area cannot be blocked with coloured glass. In such a case you would need again an ideal short-pass filter, which again is not produced in sufficient quality.\u003c\/p\u003e\u003cp style=\"box-sizing: border-box; margin: 0px 0px 1.5em; padding: 0px; font-family: \" open sans sans-serif rgb color:=\"\" font-size:=\"\" background-color:=\"\"\u003eAmateurs have tried with modest success to create a filter for stacking one UV passage without a second passage area. This meant a strongly reduced contrast and modest transmission, which is not ideal. Those who believe you can make do with a less transmission filter are soon disabused. In addition the glass of many telescope optics in the UV have a much lower transmission, which does not help.\u003c\/p\u003e\u003cp style=\"box-sizing: border-box; margin: 0px 0px 1.5em; padding: 0px; font-family: \" open sans sans-serif rgb color:=\"\" font-size:=\"\" background-color:=\"\"\u003eThe good idea of using an excellent UV-interference filter with a second window in the visible light, and evaluate only the blue channel in the resulting images of the colour camera used of course does not either. The filter on the semiconductor is subject to the same problems mentioned above. Also the blue channel gets light from the other channels added to it. Since the semiconductor is not very UV sensitive, the low leakage of the visual light tends to be shifted to the UV. This double image show significantly the effect of refraction and can make the UV detail inaccessible due to this inefficient rejection of light outside of the 320-390nm spectral range.\u003c\/p\u003e\u003cp style=\"box-sizing: border-box; margin: 0px 0px 1.5em; padding: 0px; font-family: \" open sans sans-serif rgb color:=\"\" font-size:=\"\" background-color:=\"\"\u003eWith the latest dielectric coating technology, it is possible to achieve an ideal UV characteristic with the highest transmission while blocking other transmission windows.

Here, different cloud bands, which show a steady change of details form similar to the cloud cover of Jupiter. Unfortunately, these clouds can not be seen in visible light, unlike Jupiter, meaning Venus appears completely structureless. However, by using a camera that is sensitive to inaccessible wavelengths unlike the eye, this cloud structure detail can be seen, in particular using ideal wavelengths in UV range between 320nm and 390nm.\u003c\/p\u003e\u003cp style=\"box-sizing: border-box; margin: 0px 0px 1.5em; padding: 0px; font-family: \" open sans sans-serif rgb color:=\"\" font-size:=\"\" background-color:=\"\"\u003eSince the early days of amateur astronomy, amateurs have been trying to work in this light. The difficulty is procuring a suitable filter to work precisely in this short wavelength region adequately. A sharp short-pass filter with high transmission is virtually impossible to produce. This also applies, surprisingly, to interference filters. While a theoretically ideal UV bandpass can be produced, there is inevitably at least one second passage window in the visible range. This is fatal because this undesirable area cannot be blocked with coloured glass. In such a case you would need again an ideal short-pass filter, which again is not produced in sufficient quality.\u003c\/p\u003e\u003cp style=\"box-sizing: border-box; margin: 0px 0px 1.5em; padding: 0px; font-family: \" open sans sans-serif rgb color:=\"\" font-size:=\"\" background-color:=\"\"\u003eAmateurs have tried with modest success to create a filter for stacking one UV passage without a second passage area. This meant a strongly reduced contrast and modest transmission, which is not ideal. Those who believe you can make do with a less transmission filter are soon disabused. In addition the glass of many telescope optics in the UV have a much lower transmission, which does not help.\u003c\/p\u003e\u003cp style=\"box-sizing: border-box; margin: 0px 0px 1.5em; padding: 0px; font-family: \" open sans sans-serif rgb color:=\"\" font-size:=\"\" background-color:=\"\"\u003eThe good idea of using an excellent UV-interference filter with a second window in the visible light, and evaluate only the blue channel in the resulting images of the colour camera used of course does not either. The filter on the semiconductor is subject to the same problems mentioned above. Also the blue channel gets light from the other channels added to it. Since the semiconductor is not very UV sensitive, the low leakage of the visual light tends to be shifted to the UV. This double image show significantly the effect of refraction and can make the UV detail inaccessible due to this inefficient rejection of light outside of the 320-390nm spectral range.\u003c\/p\u003e\u003cp style=\"box-sizing: border-box; margin: 0px 0px 1.5em; padding: 0px; font-family: \" open sans sans-serif rgb color:=\"\" font-size:=\"\" background-color:=\"\"\u003eWith the latest dielectric coating technology, it is possible to achieve an ideal UV characteristic with the highest transmission while blocking other transmission windows.

For best results it is advised to use a specialized camera body responsive to UV light (that does not have typical blocking filters that everyday cameras have) and a suitable UV-transmitting photographic lens which has adequate glass substrates for the transmission of UV light.\u003c\/p\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e","brand":"Baader Planetarium","offers":[{"title":"Default Title","offer_id":44013472743535,"sku":"FUV-1","price":419.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/Baader_252520U_252520filter__03181.1682640252.1280.1280.jpg?v=1766554319"},{"product_id":"baader-fringe-killer-filter-2","title":"Baader Fringe Killer Filter 2\"","description":"\u003ch3 style=\"box-sizing: border-box; margin: 0px 0px 0.75em; padding: 0px; font-size: 1.5em; color: rgb(235, 2, 53); font-family: \" open sans sans-serif optimizespeed rgb line-height:=\"\" text-rendering:=\"\" background-color:=\"\"\u003e2\" Baader Fringe Killer Filter\u003c\/h3\u003e\u003ch4 style=\"box-sizing: border-box; margin: 0px 0px 0.75em; padding: 0px; font-size: 1.2em; color: rgb(99, 99, 99); font-family: \" open sans sans-serif optimizespeed rgb line-height:=\"\" text-rendering:=\"\" background-color:=\"\"\u003ePlaneoptically polished with Phantom Group Coating\u003c\/h4\u003e\u003cdiv class=\"leftImage\" style=\"box-sizing: border-box; margin: 0px 15px 1em 0px; padding: 0px; font-family: \" open sans sans-serif center top left rgb text-align:=\"\" vertical-align:=\"\" float:=\"\" clear:=\"\" color:=\"\" font-size:=\"\" background-color:=\"\" width:=\"\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/fringe-killer-125_200_6ff8b5d9-20f7-4313-b575-65316817cdfd.jpg?v=1766554397\" alt=\"Baader Fringe Killer\" width=\"300\" style=\"box-sizing: border-box; margin: 0px; padding: 0px; border: none; display: block;\"\u003e\u003cdiv class=\"imageCaption\" style=\"box-sizing: border-box; margin: 0px; padding: 0.5em 0.5em 0px; clear: both; font-size: 0.846em;\"\u003eBaader Fringe Killer\u003c\/div\u003e\n\u003c\/div\u003e\u003cp style=\"box-sizing: border-box; margin: 0px 0px 1.5em; padding: 0px; font-family: \" open sans sans-serif rgb color:=\"\" font-size:=\"\" background-color:=\"\"\u003eThe Fringe-Killer (Fringe = colour fringing) blocks unfocused light in the red part of the spectrum (IR) - but above all suppresses over 50% of the interfering stray light in the blue spectral range - without changing the colour impression of the image.\u003c\/p\u003e\u003cp style=\"box-sizing: border-box; margin: 0px 0px 1.5em; padding: 0px; font-family: \" open sans sans-serif rgb color:=\"\" font-size:=\"\" background-color:=\"\"\u003eThe most delicate details of lunar craters and planetary surfaces are much more visible!\u003c\/p\u003e\u003cp style=\"box-sizing: border-box; margin: 0px 0px 1.5em; padding: 0px; font-family: \" open sans sans-serif rgb color:=\"\" font-size:=\"\" background-color:=\"\"\u003eThe Baader Fringe-Killer Filter prevents unwanted colour fringes in both the blue spectral range and in the IR above 700 nm! The visual impact initially corresponds to a minus violet filter, as opposed to this but the image colour remains broadly balanced. In itself a contradiction in terms? It can only be implemented by applying modern DWDM plasma assisted coating technology, which allows the application of approximately 100 individual layers on a flat-optically polished face surface perfectly and reproducibly without compromising visual quality! This fine optical precision tool also allows inexpensive refractors to reach the promised imaging performance. The reduction of chromatic aberration corresponds to what is achieved by corrections-lens systems, which usually cost 20 times more.\u003c\/p\u003e\u003cdiv class=\"emptyClear\" style=\"box-sizing: border-box; margin: 0px; padding: 0px; font-family: \" open sans sans-serif both rgb clear:=\"\" height:=\"\" font-size:=\"\" color:=\"\" background-color:=\"\"\u003e\u003c\/div\u003e\u003cdiv class=\"rightImage\" style=\"box-sizing: border-box; margin: 0px 0px 1em 15px; padding: 0px; font-family: \" open sans sans-serif center top right rgb text-align:=\"\" vertical-align:=\"\" float:=\"\" clear:=\"\" color:=\"\" font-size:=\"\" background-color:=\"\" width:=\"\"\u003e\n\u003ca class=\"image-popup\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/f_killer_vergleich_sirius_b70acc47-76e8-48e9-a025-e14ad64207be.jpg?v=1766554400\" target=\"_blank\" style=\"box-sizing: border-box; margin: 0px; padding: 0px; touch-action: manipulation; color: rgb(235, 2, 53); text-decoration-line: none; transition: all 0.2s ease 0s;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/f_killer_vergleich_sirius_b70acc47-76e8-48e9-a025-e14ad64207be.jpg?v=1766554400\" width=\"150\" height=\"144\" style=\"box-sizing: border-box; margin: 0px; padding: 0px; border: none; display: block;\"\u003e\u003c\/a\u003e\u003cdiv class=\"imageCaption\" style=\"box-sizing: border-box; margin: 0px; padding: 0.5em 0.5em 0px; clear: both; font-size: 0.846em;\"\u003eExample of Sirius with and without the Fringe Killer\u003cbr style=\"box-sizing: border-box; margin: 0px; padding: 0px;\"\u003e\u003ca class=\"image-popup\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/f_killer_vergleich_sirius_b70acc47-76e8-48e9-a025-e14ad64207be.jpg?v=1766554400\" target=\"_blank\" style=\"box-sizing: border-box; margin: 0px; padding: 0px; touch-action: manipulation; color: rgb(235, 2, 53); text-decoration-line: none; transition: all 0.2s ease 0s;\"\u003eFor comparison please click\u003c\/a\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003ch4 style=\"box-sizing: border-box; margin: 0px 0px 0.75em; padding: 0px; font-size: 1.2em; color: rgb(99, 99, 99); font-family: \" open sans sans-serif optimizespeed rgb line-height:=\"\" text-rendering:=\"\" background-color:=\"\"\u003eThe Baader Fringe Killer Overview\u003c\/h4\u003e\u003ch5 style=\"box-sizing: border-box; margin: 0px 0px 0.75em; padding: 0px; font-size: 13px; color: rgb(99, 99, 99); font-family: \" open sans sans-serif optimizespeed uppercase rgb line-height:=\"\" text-rendering:=\"\" text-transform:=\"\" background-color:=\"\"\u003eFACTS AND FIGURES\u003c\/h5\u003e\u003cul style=\"box-sizing: border-box; margin: 0px 0px 1em; padding: 0px; list-style-position: initial; list-style-image: initial; font-family: \" open sans sans-serif rgb color:=\"\" font-size:=\"\" background-color:=\"\"\u003e\n\u003cli style=\"box-sizing: border-box; margin: 0.5em 0px 0px 1.5em; padding: 0px;\"\u003eRemoves blue fringing as well as red fringing above 700nm.\u003c\/li\u003e\n\u003cli style=\"box-sizing: border-box; margin: 0.5em 0px 0px 1.5em; padding: 0px;\"\u003eForms in the range between 450 to 480 nm with a plateau at around 50% transmission rate, the coating becomes more complex to produce than even the narrowest Nebula filters.\u003c\/li\u003e\n\u003cli style=\"box-sizing: border-box; margin: 0.5em 0px 0px 1.5em; padding: 0px;\"\u003eAchieved in the passband the highest transmission rate of all previously available colour fringe, whether filter or correction lens.

No other spectral line of emission nebulae will give you so much information for the creation of \"pretty pictures\" as this Hydrogen-line. This is supported by the better coatings, sensitive CCD-cameras, motorized focusers and last but not least the the incredible tracking precision of modern mounts, which allow for very long exposure times with very narrow-band filters. Modern images are often based on exposure times of 30 hours through the three common, very narrow-band nebula filters. But to make use of this, the mount must provide \"subpixel\"-tracking, the focuser must not flex even for a micron, and its motor must compensated for temperature changes by keeping the focus up to a fraction of a millimeter...

Quantum-mechanics define a fixed ratio between H-Alpha and H-Beta, but because of the shorter wavelengths, H-Beta has got a higher energy. That's why H-Beta suffers from a higher extinction rate in interstellar dust regions, which can easily be detected. The ratio between H-Beta and H-Alpha gives you information about the amount of dust between us and the source, which is especially interesting for scientific work. For astrophotography, you can scale down the intensity of H-Alpha to simulate an H-Beta-filter – and if you are observing with your eyepiece, you will see structures which were almost invisible before.\u003c\/p\u003e\u003cp style=\"box-sizing: border-box; margin: 0px 0px 1.5em; padding: 0px; font-family: \" open sans sans-serif rgb color:=\"\" font-size:=\"\" background-color:=\"\"\u003eVisual observers profit from the fact that a H-Beta-filter can show the dust regions in hydrogen-emitting nebulae quite clearly, similar to a photographical H-Alpha-filter.

The true dimensions of the sometimes very long dust tail may only be recognizable in the eyepiece with the help of a H-Beta-filter.

Using these filters between f\/1,8 and f\/3,5 shows a dramatic improvement compared to any regular set of narrowband-filters. \u003c\/span\u003e\u003c\/span\u003e  \u003c\/div\u003e","brand":"Baader Planetarium","offers":[{"title":"Default Title","offer_id":44013574488175,"sku":"FHSS-2","price":1399.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/baader_252520NB_252520f2__59008.1682640493.1280.1280.jpg?v=1766556691"},{"product_id":"baader-l-rgb-ccd-filterset-1-25","title":"Baader L-RGB CCD-Filterset 1.25\"","description":"\u003cspan style=\"font-family: Arial; background-color: rgb(255, 255, 255); font-size: 10pt;\"\u003e\u003cbr\u003e\u003cstrong\u003eThis filter set consists of:\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e-- 1.25\" Interference filter red\u003cbr\u003e-- 1.25\" Interference filter blue\u003cbr\u003e-- 1.25\" Interference filter green\u003cbr\u003e-- 1.25\" UV\/IR cut filter for luminance\u003cbr\u003e\u003cbr\u003eEach filter comes in a robust plastic box for gentle and dust-proof storage.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan style=\"font-family: Arial; background-color: rgb(255, 255, 255); font-size: 10pt;\"\u003e\u003cstrong\u003eGeneral information about the Baader interference filters:\u003cbr\u003e\u003cbr\u003e\u003c\/strong\u003eThese new filters by Baader guarantee highest contrast due to the steep transmission curve's edges.

It can only be implemented by applying modern DWDM plasma assisted coating technology, which allows the application of approximately 100 individual layers on a flat-optically polished face surface perfectly and reproducibly without compromising visual quality! This fine optical precision tool also allows inexpensive refractors to reach the promised imaging performance.

Our favorite filter for the majority of nebula, especially The Veil, Lagoon (M8), Swan (M17), Ring (M57) and Dumbell (M29).

Unlike other O-III filters, the Baader O-III completely blocks longer and shorter wavelengths (ever wonder why some O-III filters appear RED?, instead of the correct 500 nm Teal color). The result is the highest contrast achievable in an O-III filter.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); margin-top: 1rem; margin-bottom: 1rem; color: rgb(76, 81, 84); font-family: \" libre franklin sans-serif font-size:=\"\"\u003eThe O-III benefits from the precision fineoptically polished flat substrate, and advanced DWDM plasma assisted coatings. As a result, the Baader O-III will not degrade image sharpness or impart double images. To prevent deterioration from cleaning or exposure to moisture, some other filters even resort to sandwiching their delicate coatings between two layers of filter glass, resulting in potential blurred or double images. Contrary to myth, nebula filters are often useful at high magnifications, where image quality counts. Baader O-III filters can take high magnifications, and stars retain their pinpoint sharpness, even if the filter is used far ahead of the image plane (ie, for imaging use, or ahead of a star diagonal or binoviewer).

The Semi-APO works like it's name implies - delivering a very neutral view, while cutting most of the annoying and contrast-robbing violet fringe that plagues all achromats. The Semi-APO filter combines a stronger Fringe Killer coating formula with the Moon\u0026amp;Skyglow Neodymium substrate. The result is similar performance to the Fringe Killer + Moon\u0026amp;Skyglow combination, but with a slightly stronger violet cut - and at an even greater $$ value.\u003cbr style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: transparent;\"\u003e\u003cbr style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: transparent;\"\u003eThe Semi-APO filter benefits from all the host of world-class Baader filter attributes. The Semi-APO filter is truly the world's most advanced 'minus-violet' type filter in every regard. It's high efficiency and neutral coloration make it practically disappear in use - while making most of the violet fringe disappear! The effects on sharpness, contrast, and aesthetics are remarkable, even with small refractors. The RGB enhancement of the Neodymium substrate actually boosts color contrasts, particularly for Jupiter and Mars.\u003cbr style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: transparent;\"\u003e\u003cbr style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: transparent;\"\u003eAs a side benefit, the Semi-APO filter has also proven to be the best Mars filter we've used - with ALL Telescopes, including large Dobsonians, SCTs, and Apochromats. The unique properties that result from the combination of the Fringe Killer's blue wavelength attenuation (attenuation - not total elimination), plus the selective Neodymium RGB passbands, result in a significant contrast enhancement of Martian features. The image retains its natural coloration and brightness, and the optically polished surfaces maintain every bit of the image sharpness, unlike other manufacturer's filters.\u003cbr style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: transparent;\"\u003e\u003cbr style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: transparent;\"\u003eThe high quality of Baader Planetarium filters permits their use well ahead of the focal plane with no image degradation (ie, for cameras or binoviewers). The inclusion of Baader's renowned UV\/IR Cut coatings on the Semi-APO eliminate UV and IR wavelengths to make it ideal for high-resolution imaging with Webcams, DSLR, and CCD cameras (see the UV\/IR Cut filter below, for more detail on these coatings). The high transmission and fringe reduction work great for both planetary and deep sky imaging.\u003cbr style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: transparent;\"\u003e\u003c\/p\u003e","brand":"Baader Planetarium","offers":[{"title":"Default Title","offer_id":44013683671151,"sku":"FSAPO-2","price":210.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/Semi_252520APO_2525202__88570.1682640796.1280.1280.jpg?v=1766559681"},{"product_id":"baader-6-5nm-narrowband-filters-cmos-optimized-h-alpha-o-iii-s-11-36mm","title":"Baader 6.5nm Narrowband Filters – CMOS-optimized (H-alpha, O-III, S-11) 36mm","description":"\u003cul style=\"box-sizing: inherit;

The Semi-APO works like it's name implies - delivering a very neutral view, while cutting most of the annoying and contrast-robbing violet fringe that plagues all achromats. The Semi-APO filter combines a stronger Fringe Killer coating formula with the Moon\u0026amp;Skyglow Neodymium substrate. The result is similar performance to the Fringe Killer + Moon\u0026amp;Skyglow combination, but with a slightly stronger violet cut - and at an even greater $$ value.\u003cbr style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: transparent;\"\u003e\u003cbr style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: transparent;\"\u003eThe Semi-APO filter benefits from all the host of world-class Baader filter attributes. The Semi-APO filter is truly the world's most advanced 'minus-violet' type filter in every regard. It's high efficiency and neutral coloration make it practically disappear in use - while making most of the violet fringe disappear! The effects on sharpness, contrast, and aesthetics are remarkable, even with small refractors. The RGB enhancement of the Neodymium substrate actually boosts color contrasts, particularly for Jupiter and Mars.\u003cbr style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: transparent;\"\u003e\u003cbr style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: transparent;\"\u003eAs a side benefit, the Semi-APO filter has also proven to be the best Mars filter we've used - with ALL Telescopes, including large Dobsonians, SCTs, and Apochromats. The unique properties that result from the combination of the Fringe Killer's blue wavelength attenuation (attenuation - not total elimination), plus the selective Neodymium RGB passbands, result in a significant contrast enhancement of Martian features. The image retains its natural coloration and brightness, and the optically polished surfaces maintain every bit of the image sharpness, unlike other manufacturer's filters.\u003cbr style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: transparent;\"\u003e\u003cbr style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: transparent;\"\u003eThe high quality of Baader Planetarium filters permits their use well ahead of the focal plane with no image degradation (ie, for cameras or binoviewers). The inclusion of Baader's renowned UV\/IR Cut coatings on the Semi-APO eliminate UV and IR wavelengths to make it ideal for high-resolution imaging with Webcams, DSLR, and CCD cameras (see the UV\/IR Cut filter below, for more detail on these coatings). The high transmission and fringe reduction work great for both planetary and deep sky imaging.\u003cbr style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: transparent;\"\u003e\u003c\/p\u003e","brand":"Baader Planetarium","offers":[{"title":"Default Title","offer_id":44038681100399,"sku":"FSAPO-1","price":94.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/fsapo-1_11_2__08679.jpg?v=1767595370"},{"product_id":"baader-6-5nm-f-2-highspeed-filters-cmos-optimized-h-alpha-o-iii-s-11-36mm","title":"Baader 6.5nm f\/2 Highspeed Filters – CMOS-optimized (H-alpha, O-III, S-11) 36mm","description":"\u003cspan style=\"color: rgb(76, 81, 84); font-family: \" libre franklin sans-serif rgb font-size:=\"\" background-color:=\"\"\u003eAfter two hard years of development and significant investment in R\u0026amp;D, the new Baader CMOS optimized (ultra-) narrowband and highspeed filters are imminent.
