The high transmission of our optical glass filters means that enough light is available to allow successful visual observations with telescopes beginning at 2\" (50mm) aperture. Our Astronomik filters are optimized for use with telescope focal length f \/ ratios of f\/4 to f\/15. Transmission losses and chromatic distortions, which arise with other filters, only occur with Astronomik filters when extremely bright aperture ratios of 1:2 and more come into play. Another major advantage of our Astronomik UHC filter is the high optical quality of the filter glass.

You want as much signal as possible so the filter should have the highest transmission possible with a wide spectral bandpass. This combination provides the greatest sensitivity and gives you the highest photon counts on your pixels. While the high transmission level is a great aspect of the new Astronomik Luminance filters, not all optical instruments or additional optical elements like correctors, field-flatteners or reducers, have perfect color correction so it can be the width of the spectral band pass of  the Luminance filter that can cause problems. A band pass that is too wide will allow the transmission of incompletely focused light (Chromatic aberration), making stars appear soft or bloated. In such cases image processing can become difficult, so having a slightly narrowed spectral window in your Luminance filter can reduce or eliminate this damaging effect.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eTo give you all the tools to gather the best data possible\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ewe have expanded our line of Luminance filters\u003c\/strong\u003e: Now you can select a Luminance filter perfectly matched to the kind of telescope you use, to get the highest signal and sharpest image for the Luminance channel!\u003cbr\u003eDepending on the color correction of your scope you may use a wider spectral window for the Luminance data. The L1 filter has the widest spectral window, the L2 is about the same as our current L-Filter and the L3 is much narrower.\u003cbr\u003eIf you use an optical system that is completely free of any chromatic aberration you should get an L1 filter for your setup. For general use the L2 filter is well suited to most optical systems with a corrector, flattener or reducer in the optical train while the L3 filter is designed for users of refractors with a less-than-perfect color correction and in combination with the new Deep-Sky RGB filters, the L3 filter will minimize the problem of bluish halos around stars.\u003cbr\u003e\u003cbr\u003eThe transmission curve characteristics and coatings on the new Luminance filters have been designed and engineered in such a way that no halos or reflections will be visible. Even with bright stars in the field of view you will be able to reveal the faintest structures in nebulas or galaxies.\u003cbr\u003e\u003cbr\u003eLike all Astronomik Filters, the new Luminance filters are made using an extremely durable and scratch resistant coating, deposited on the finest polished optical substrate, which is free of any striae or internal strains. All substrates are made to exactly the same thickness, so all of our filters are parfocal.\u003cbr\u003e\u003cbr\u003e\u003cspan\u003e\u003cstrong\u003eAdditional note for observers working under light polluted skies:\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003eIf your observing site suffers from light pollution you should try to use our CLS-CCD as a replacement for the Luminance filter.

It should be noted that the filter has a transmission of up to 99%, which cannot be attained by stacking more narrow-band filters. A further note, which led to selecting the half width (FWHM), is the dark current of common CCD imagers.

Every observer knows the flickering stars and planetary disks when looking through an eyepiece or at your monitor Slight differences in temperature and pressure result in a different index of refraction for \"bubbles\" of air. As these bubbles move, the image moves too! This effect is called \"Seeing\".\u003cbr\u003eThis change in the index of refraction becomes smaller the further you go to the infrared (longer wavelengths), and due to that, the Seeing becomes better too!\u003cbr\u003eWhen observing with the human eye we have no options: The human eye is not sensitive to infrared light. But with the CCD or CMOS sensors from our camera we can go to the infrared part of the spectrum and enjoy the steady air.\u003cbr\u003eAn Infrared-Pass filter like the Astronomik ProPlanet 642 BP blocks all unwanted visual light and gives you infrared light only!\u003cbr\u003eThe amount of seeing is changing very fast, so there is no universal filter that will do it every time. So the Astronomik ProPlanet 642 BP is the third filter in this line of Products in addition to the Astronomik ProPlanet 742 and ProPlanet 807! When seeing is no really bad, the ProPlanet 642 BP will be usually the first choice and will give you best results as it blocks the longer IR too!\u003cbr\u003eWhile we were developing this new filter, several observers had our prototype filters for testing. Most of them reported that the Astronomik ProPlanet 642 BP gave them the very best images compared with filters from other manufacturers.

Compared to the 6nm filters you have more stars in the field of view which gives you more guiding stars when working with an integrated\/dual guiding chip!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDue to the new MFR coating technique you may use one single filter on all instruments up to f\/3 without a significant reduction in performance.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Astronomik H-alpha filter MUST NOT BE USED for solar observation!\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch1\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003eGuaranteed Transmission of more than 90% at the H-alpha Line (656 nm)\u003c\/li\u003e\n\u003cli\u003eTypical Transmission of 96% at the H-alpha Line (656 nm)\u003c\/li\u003e\n\u003cli\u003eFull-Width-Half Maximum (FWHM): 12nm\u003c\/li\u003e\n\u003cli\u003eperfect blocking of unwanted light from UV up to the IR\u003c\/li\u003e\n\u003cli\u003eparfokal with all Astronomik filters\u003c\/li\u003e\n\u003cli\u003eMFR Coating technique: Usable with all optics up to f\/3\u003c\/li\u003e\n\u003cli\u003eThickness of 1mm\u003c\/li\u003e\n\u003cli\u003eNot sensitive to moisture, scratch resistant, not aging\u003c\/li\u003e\n\u003cli\u003eopticaly polished substrate, striae-free and free of residual stresses\u003c\/li\u003e\n\u003cli\u003eHigh quality storage box\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Astronomik","offers":[{"title":"1.25\" \/ 0","offer_id":45358278836544,"sku":"8h0050","price":149.95,"currency_code":"USD","in_stock":true},{"title":"2\" \/ 0","offer_id":45358278869312,"sku":"8h0051","price":329.95,"currency_code":"USD","in_stock":true},{"title":"EOS APS-C \/ 0","offer_id":45358278902080,"sku":"8h00ih","price":219.95,"currency_code":"USD","in_stock":true},{"title":"EOS APS-C XT \/ 0","offer_id":45358278934848,"sku":"8h00kh","price":239.95,"currency_code":"USD","in_stock":true},{"title":"EOS XL \/ 0","offer_id":45358278967616,"sku":"8h00lf","price":339.95,"currency_code":"USD","in_stock":true},{"title":"EOS R XL \/ 0","offer_id":45358279000384,"sku":"8h11gj","price":359.95,"currency_code":"USD","in_stock":true},{"title":"EOS M \/ 0","offer_id":45358279033152,"sku":"8h00s2","price":229.95,"currency_code":"USD","in_stock":true},{"title":"Sony alpha 7 \/ 0","offer_id":45358279065920,"sku":"8h00xg","price":359.95,"currency_code":"USD","in_stock":true},{"title":"Nikon XL \/ 0","offer_id":45358279098688,"sku":"8h11aw","price":359.95,"currency_code":"USD","in_stock":true},{"title":"Nikon Z XL \/ 0","offer_id":45358279131456,"sku":"8h11l4","price":359.95,"currency_code":"USD","in_stock":true},{"title":"Pentax K-1 \/ 0","offer_id":45358279164224,"sku":"8h11el","price":359.95,"currency_code":"USD","in_stock":true},{"title":"T-Mount (M42x0,75) \/ 0","offer_id":45358279196992,"sku":"8h00ah","price":289.95,"currency_code":"USD","in_stock":true},{"title":"SC Rear Cell \/ 0","offer_id":45358279229760,"sku":"8h00ai","price":339.95,"currency_code":"USD","in_stock":true},{"title":"31mm \/ 0","offer_id":45358279262528,"sku":"8h00fn","price":179.95,"currency_code":"USD","in_stock":true},{"title":"36mm \/ 0","offer_id":45358279295296,"sku":"8h00fo","price":209.95,"currency_code":"USD","in_stock":true},{"title":"50mm \/ 0","offer_id":45358279328064,"sku":"8h00a4","price":329.95,"currency_code":"USD","in_stock":true},{"title":"M49 \/ 0","offer_id":45358279360832,"sku":"8h11js","price":329.95,"currency_code":"USD","in_stock":true},{"title":"M52 \/ 0","offer_id":45358279393600,"sku":"8h11a8","price":339.95,"currency_code":"USD","in_stock":true},{"title":"27mm, unmounted \/ 0","offer_id":45358279426368,"sku":"8h00mh","price":139.95,"currency_code":"USD","in_stock":true},{"title":"42mm, unmounted \/ 0","offer_id":45358279459136,"sku":"8h11bf","price":239.95,"currency_code":"USD","in_stock":true},{"title":"50 x 50mm² square, unmounted \/ 0","offer_id":45358279491904,"sku":"8h00hm","price":359.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0717\/9904\/6464\/products\/Astronomik_H-alpha-CCD-6nm_1_25-Inch_6_dcf9f20c-7bb2-4b5c-83e4-cbc55e4ea392.jpg?v=1687106896"},{"product_id":"astro-hutech-idas-lps-p2-filter","title":"IDAS ODW filter","description":"\u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003eEnhance your astrophotography with the Astro Hutech IDAS NBZ filter 2\".
