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.

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. This has made it possible for the first time for an amateur astronomer to photographically observe the changing clouds of Venus and to say goodbye to the vacuous white crescent. All Baader filters are finely polished optically (increases image quality). High magnification during eyepiece projection is also possible, without reducing the sharpness of the optics.\u003c\/p\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\u003ca class=\"image-popup\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/primel_3815bdf4-45d1-46e7-bcc2-18725aec9553.jpg?v=1766554292\" 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 alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/primel_3815bdf4-45d1-46e7-bcc2-18725aec9553.jpg?v=1766554292\" width=\"150\" style=\"box-sizing: border-box; margin: 0px; padding: 0px; border: none; display: block;\"\u003e\u003c\/a\u003e\u003c\/div\u003e\u003chr style=\"box-sizing: border-box; margin: 0px; padding: 0px; color: rgb(34, 34, 34); font-family: \" open sans sans-serif rgb font-size:=\"\" background-color:=\"\"\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:=\"\"\u003e \u003c\/p\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\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/u_filter_9dea3507-7a4b-4819-9210-3d6813f1a675.jpg?v=1766554295\" height=\"122\" width=\"150\" style=\"box-sizing: border-box; margin: 0px; padding: 0px; border: none; display: block;\"\u003e\u003c\/div\u003e\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:=\"\"\u003eNon-Astronomical Application Areas\u003c\/h3\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:=\"\"\u003eThese filters can be used in the observation, by technical photography, of nature.

However, we do produce a family of adaptor rings to mount any of our 2 inch (50.8mm) filters in front of any camera lens which has a filter thread. It is important to note that not all cameras and lenses are suited to UV photography and this could result in a low signal to noise ratio in the image produced. 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":44013472710767,"sku":"FUV-2","price":556.49,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/Baader_252520U_252520filter__80456.1682640250.1280.1280.jpg?v=1766554297"},{"product_id":"baader-h-beta-8-5nm-ccd-narrowband-filter-2","title":"Baader H-beta 8.5nm CCD Narrowband-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:=\"\"\u003e\n\u003cspan style=\"box-sizing: border-box; margin: 0px; padding: 0px; color: rgb(94, 169, 221);\"\u003eBaader H-Beta-Filter\u003c\/span\u003e \u003cspan style=\"box-sizing: border-box; margin: 0px; padding: 0px; color: rgb(99, 99, 99);\"\u003e– the\u003c\/span\u003e H-Alpha-Filter \u003cspan style=\"box-sizing: border-box; margin: 0px; padding: 0px; color: rgb(99, 99, 99);\"\u003efor visual observations!\u003c\/span\u003e\n\u003c\/h3\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 \u003cstrong style=\"box-sizing: border-box; margin: 0px; padding: 0px;\"\u003eBaader H-Beta-Filter with 8.5nm half width\u003c\/strong\u003e is especially useful at telescopes with 8\" or larger apertures or if you are working with large exit pupils.

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... All this is possible – but you need high-end equipment.\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:=\"\"\u003e\u003cstrong style=\"box-sizing: border-box; margin: 0px; padding: 0px;\"\u003eThis is not necessary for visual observations.\u003c\/strong\u003e But unfortunately, we do not profit from those photographically wonderful filters when we are looking through the eyepiece – at low intensities at night, the human eye is almost blind for this part of the spectrum.

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.

Especially light with shorter wavelengths will be scattered more in the dust tail, so that the contrast to its surroundings increases. Light with even shorter wave-lengths will be scattered even more, but our eye is not so sensitive for these parts of the spectrum. 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. The H-Beta line is also outside of the prominent lines of the gas tail, so the dust tail can be better deiscerned from the gas tail – and the contrast is increased even more.\u003c\/p\u003e","brand":"Baader Planetarium","offers":[{"title":"Default Title","offer_id":44013569867887,"sku":"FHBN-2","price":314.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/baader-h-beta-85nm-ccd-narrowband-filter-2-99a__37995.jpg?v=1766556581"},{"product_id":"set-of-3-f-2-highspeed-filters-h-a-o-iii-s-ii-2","title":"Set of 3 f\/2 Highspeed-Filters (H-a\/O-III\/S-II) 2\"","description":"\u003cspan style=\"font-weight: bold; font-family: Arial;\"\u003eBaader's New f\/2 Highspeed Narrowband Filters and Filtersets\u003c\/span\u003e\u003cspan style=\"font-size: 12pt; text-align: justify; background-color: rgb(255, 255, 255); font-family: Arial;\"\u003e \u003c\/span\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 12pt; text-align: justify; background-color: rgb(255, 255, 255); font-family: Arial;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan style=\"font-size: 14pt; text-align: justify; background-color: rgb(255, 255, 255); font-family: Arial;\"\u003e(2\" H-alpha \/ O-III \/ S-II) are designed especially for the delicate requirements of extremely fast astrograph optics, such as Hyperstar, RASA, and ultra-fast instruments from TEC\/AP\/ASA\/etc. Conventional narrowband filters cause a heavy loss in transmission due to the strong CWL-shift.

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).
