The extremely narrow pass band of the two OIII lines brings a substantial contrast gain to these lines even under best observation conditions. On faint super nova remnants and faint planetary nebulae the Astronomik OIIIfilter will often make the difference as to whether the object can bee seen or not!\u003c\/strong\u003e The optimal aperture ratio for the use of the filter is 1:3 to 1:15 with apertures of more than 6\" (150mm). Transmission losses and chromatic distortions, which arise with other filters, occur with Astronomik OIII filters only when extremely bright aperture ratios of 1:3 and more come into play. The Astronomik OIII filters thus can expand the view of dispersed objects, generally speaking, to the whole visual field of view of the eyepiece and are not limited to only the center of the eyepiece.\u003c\/p\u003e\n\u003ch4\u003eMain use\u003c\/h4\u003e\n\u003cp\u003eSince enough light must be available to make use of the OIII filter it is best to use this filter with apertures of more than 6\" (150mm). Smaller instruments do not gather enough light for meaningful and satisfying astronomical work. However, please note: Many experienced Deep Sky observers, with apertures of more than 10\" (250mm), prefer using the OIII filter instead of the more versatile UHC filter. Due to the high optical quality of the Astronomik OIII filter substrate you will see the same needle-sharp stars as you would from your regular telescope.

We have created the most advanced set of RGB filters for Deep-Sky imaging available today.\nThe transmission curves of the three filters are designed to give you strong and vivid colors with a strong reinforcement of the most important emission lines. Data taken with the new Astronomik Deep-Sky RGB filters is easier to process into a beautiful final masterpiece.\n\nFeedback from our test-users and the first customers is really exciting. All of them reported smaller, sharper stars and this was one of our design goals, so these filters are designed to give you the best contrast and the smallest stars possible!\n\nDuring the design of the Deep-Sky RGB filters we took a close look at the sensitivity curves of today’s popular CCD cameras. The result was we found a way to make one set of filters for all kind of sensors ranging from KAF- and KAI-sensors, to the chips made by Sony, meaning you can do 1:1:1 ratio RGB exposures with all sensors, with only minimal tweaking necessary during processing to achieve perfect colours in your image!\n\nThe transmission curve characteristics and coatings on the new Deep Sky RGB 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\n\nAdditional to the Deep-Sky RGB filters Astronomik now offers you three different Luminance filters. The different spectral window of each new Luminance filters is designed to tune your setup to get the sharpest image from any optical design and any camera, even with instruments with less-than-perfect colour correction. (Link einfügen)\n\nLike all Astronomik Filters, the new Deep-Sky RGB 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.","brand":"Astronomik","offers":[{"title":"1.25\" Round","offer_id":43460188569829,"sku":"AK-8H00PC","price":393.0,"currency_code":"CAD","in_stock":true},{"title":"2\" Round","offer_id":43460188602597,"sku":"AK-8H00PN","price":815.0,"currency_code":"CAD","in_stock":true},{"title":"27mm Round","offer_id":43460188635365,"sku":"AK-8H00O7","price":353.0,"currency_code":"CAD","in_stock":true},{"title":"31mm Round","offer_id":43460188668133,"sku":"AK-8H00PY","price":461.0,"currency_code":"CAD","in_stock":true},{"title":"36mm Round","offer_id":43460188700901,"sku":"AK-8H00QJ","price":543.0,"currency_code":"CAD","in_stock":true},{"title":"50mm Round","offer_id":43460188733669,"sku":"AK-8H00QU","price":815.0,"currency_code":"CAD","in_stock":true},{"title":"50x50mm Square","offer_id":43460188766437,"sku":"AK-8H00RF","price":952.0,"currency_code":"CAD","in_stock":true},{"title":"27mm unmounted","offer_id":44127595331813,"sku":"AK-8h00o7","price":353.0,"currency_code":"CAD","in_stock":true},{"title":"42mm unmounted","offer_id":44127595364581,"sku":"AK-8h11bu","price":611.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/astronomik-deep-sky-rgb-filter-astronomy-plus-1.webp?v=1690487921"},{"product_id":"astronomik-cls-ccd-filter","title":"Astronomik CLS-CCD filter","description":"\u003ch2\u003eAstronomik CLS-CCD filter\u003c\/h2\u003e\n\u003cp\u003eThe Astronomik CLS CCD is suitable under light-polluted skies for DSLR Cameras, which have been remodeled for astronomical use.

This filter should be used on telescopes with a diameter of 8 \" (20cm) or larger. Smaller instruments do not gather enough light for meaningful and satisfying astronomical work.

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 colour 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\u003eTo give you all the tools to gather the best data possible we have expanded our line of Luminance filters: 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!\u003c\/p\u003e\n\u003cp\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. If 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 minimise the problem of bluish halos around stars.\u003c\/p\u003e\n\u003cp\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.

More important a tool should be given to the astrophotographers that offers a simple and elegant editing process. To maintain the colour, we calculated our filterset for the sRGB color space, which is used as an industry standard from most manufacturers of monitors, printers, and imaging software. As a user, you do not need to spend time to learn about colour spaces. We have solved the special problems of astrophotography for you. Due to the high-precision machining of the carrier substrate, our filters are parfocal with wedge errors below all usual margins. In order not to be the bottleneck in a high-quality optical system Astronomik filters are of course diffraction limited. Issues concerning focal distances as well as the exact location of the images of each colour image are not a problem at all!\u003c\/p\u003e\n\u003ch4\u003eMain use\u003c\/h4\u003e\n\u003cp\u003eThe L-RGB filter set divides the spectrum into its components red, green, blue, and luminance. Thus colour separation can be achieved with pure b\/w CCD sensors. The separation corresponds to the colour sensitivity of the human eye according to DIN 5032. By using the sRGB color space it is possible to maintain the color of the image throughout the entire image processing and output. With an Astronomik L-RGB filter set and your camera, you create the ideal raw material for image processing in the sRGB color space.\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp\u003e1.25\"\u003c\/p\u003e\n\u003ctable style=\"box-sizing: border-box;

The Astronomik filter should be used as a standard at all imaging applications with sensors having a low sensitivity in the UV, e.g. Webcam, DSI and LPI from Meade or most video systems. Put this filter in front of your camera and you will get rid of all problems caused by IR like bright halos around all objects and a very soft overall image. If you compare the transmission data of the Astronomik IR-blocker with the data from other sources, you will notice, that most other manufacturers would call this already an UV-IR blocker.

The set allows to take images in correct colour for all types of objects. Where other brands make strange compromises, we do the best colour reproduction possible.

You get CCD images with perfect colors, as if the objects where bright enough to be seen with photopic vision. This feature is the main difference between Astronomik filters an those of other manufacturers. The following aspects have been most important for the design of our filterset: - simple image processing for the user - highest transmission (nearly 100%) for short exposure times - adjusted transmissions of the individual filters for optimal colour reproduction - the use of industry standards Astronomik doesn't stop thinking at the step of taking the picture. More important a tool should be given to the astrophotographers that offers a simple and elegant editing process.

These filters provide a natural color reproduction of planets, stars, emission- and reflection nebulas. The transmission properties of the L-RGB Typ 2c filters are optimized for CCD astrophotography. The set allows to take images in correct colour for all types of objects. Where other brands make strange compromises, we do the best colour reproduction possible. Both stars as well as objects that emit only in spectral lines, are reproduced in their true colors. You get CCD images with perfect colors, as if the objects where bright enough to be seen with photopic vision. This feature is the main difference between Astronomik filters an those of other manufacturers. The following aspects have been most important for the design of our filterset: - simple image processing for the user - highest transmission (nearly 100%) for short exposure times - adjusted transmissions of the individual filters for optimal colour reproduction - the use of industry standards Astronomik doesn't stop thinking at the step of taking the picture. More important a tool should be given to the astrophotographers that offers a simple and elegant editing process. To maintain the colour, we calculated our filterset for the sRGB color space, that is used as an industry standard from most manufacturers of monitors, printers and imaging software. As a user you do not need to spend time to learn about colourimetry and colour spaces. We have solved the special problems of astrophotography for you. Due to the high-precision machining of the carrier substrate, our filters are parfocal with wedge errors below all usual margins. In order not to be the bottleneck in a high-quality optical system Astronomik filters are of course diffraction limited. Issues concerning focal distances as well as the exact location of the images of each colour image are not a problem at all!\u003c\/p\u003e\n\u003ch4 data-mce-fragment=\"1\"\u003eMain use\u003c\/h4\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe L-RGB filter set divides the spectrum into its components red, green, blue and luminance. Thus colour separation can be achieved with pure b\/w CCD sensors. The separation corresponds to the colour sensitivity of the human eye according to DIN 5032.

A general \"right\" or \"wrong\" or \"best\" does not make any sense. We would not offer both series if they were not needed.\u003cbr\u003eIf you have a camera with an extremly low dark current and effective cooling, the 6nm filters will give you major advantages: Due to the stronger blocking of the background you will be able to expose longer and get deeper images! All stars are very tiny points, most faint stars do not show up anymore! -This is a major advantage even for normal cameras, as you can take images of faint structures even in star-crowded regions of the milkyway!\u003cbr\u003eTo put it short: 12nm Filters are the right choice for all DSLRs and dark-current limited cameras.\u003cbr\u003e6nm filters are the best choice for observing sites with extrem strong light pollution, cameras with low dark-current and when weak objects require the maximum contrast and star-reduction possible!\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eHow much is exposure time increased?\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis question is asked quite often, and the answer is very easy: You don have to expose longer, but you MAY expose longer!\u003cbr\u003eDue to the high transmission of approximately 100% at the center wavelength nearly all emission line photons reach the sensor. So the number of for example \"H-alpha-photons\" does not change significant wether a H-alpha filter is installed or not. But looking at the photons of other wavelength, which wi do NOT want to record makes the effect of the filter clear: The combination of a very good blocking of all unwanted light from UV up to the IR and the narrow bandwidth of the filters reduces all unwanted signal on the sensor! If you do an exposure of 30sec without any filters from a lightpolluted urban observing site, your sky-background might be allready very, very bright or even saturated. The same image taken with an Narrowband-Emissionline filter will give you a perfect black background without any signal and the signal from the object will be about the same. With this black background you have the possibility to expose longer -propably 30min instead- to record fainter structures!

A general \"right\" or \"wrong\" or \"best\" does not make any sense. We would not offer both series if they were not needed.\u003cbr\u003eIf you have a camera with an extremly low dark current and effective cooling, the 6nm filters will give you major advantages: Due to the stronger blocking of the background you will be able to expose longer and get deeper images! All stars are very tiny points, most faint stars do not show up anymore! -This is a major advantage even for normal cameras, as you can take images of faint structures even in star-crowded regions of the milkyway!\u003cbr\u003eTo put it short: 12nm Filters are the right choice for all DSLRs and dark-current limited cameras.\u003cbr\u003e6nm filters are the best choice for observing sites with extrem strong light pollution, cameras with low dark-current and when weak objects require the maximum contrast and star-reduction possible!\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eHow much is exposure time increased?\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis question is asked quite often, and the answer is very easy: You don have to expose longer, but you MAY expose longer!\u003cbr\u003eDue to the high transmission of approximately 100% at the center wavelength nearly all emission line photons reach the sensor. So the number of for example \"H-alpha-photons\" does not change significant wether a H-alpha filter is installed or not. But looking at the photons of other wavelength, which wi do NOT want to record makes the effect of the filter clear: The combination of a very good blocking of all unwanted light from UV up to the IR and the narrow bandwidth of the filters reduces all unwanted signal on the sensor! If you do an exposure of 30sec without any filters from a lightpolluted urban observing site, your sky-background might be allready very, very bright or even saturated. The same image taken with an Narrowband-Emissionline filter will give you a perfect black background without any signal and the signal from the object will be about the same. With this black background you have the possibility to expose longer -propably 30min instead- to record fainter structures!

A general \"right\" or \"wrong\" or \"best\" does not make any sense. We would not offer both series if they were not needed.\u003cbr\u003eIf you have a camera with an extremly low dark current and effective cooling, the 6nm filters will give you major advantages: Due to the stronger blocking of the background you will be able to expose longer and get deeper images! All stars are very tiny points, most faint stars do not show up anymore! -This is a major advantage even for normal cameras, as you can take images of faint structures even in star-crowded regions of the milkyway!\u003cbr\u003eTo put it short: 12nm Filters are the right choice for all DSLRs and dark-current limited cameras.\u003cbr\u003e6nm filters are the best choice for observing sites with extrem strong light pollution, cameras with low dark-current and when weak objects require the maximum contrast and star-reduction possible!\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eHow much is exposure time increased?\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis question is asked quite often, and the answer is very easy: You don have to expose longer, but you MAY expose longer!\u003cbr\u003eDue to the high transmission of approximately 100% at the center wavelength nearly all emission line photons reach the sensor. So the number of for example \"H-alpha-photons\" does not change significant wether a H-alpha filter is installed or not. But looking at the photons of other wavelength, which wi do NOT want to record makes the effect of the filter clear: The combination of a very good blocking of all unwanted light from UV up to the IR and the narrow bandwidth of the filters reduces all unwanted signal on the sensor! If you do an exposure of 30sec without any filters from a lightpolluted urban observing site, your sky-background might be allready very, very bright or even saturated. The same image taken with an Narrowband-Emissionline filter will give you a perfect black background without any signal and the signal from the object will be about the same. With this black background you have the possibility to expose longer -propably 30min instead- to record fainter structures!

So the number of for example \"H-alpha-photons\" does not change significant wether a H-alpha filter is installed or not. But looking at the photons of other wavelength, which wi do NOT want to record makes the effect of the filter clear: The combination of a very good blocking of all unwanted light from UV up to the IR and the narrow bandwidth of the filters reduces all unwanted signal on the sensor! If you do an exposure of 30sec without any filters from a lightpolluted urban observing site, your sky-background might be allready very, very bright or even saturated.

So the number of for example \"H-alpha-photons\" does not change significant wether a H-alpha filter is installed or not. But looking at the photons of other wavelength, which wi do NOT want to record makes the effect of the filter clear: The combination of a very good blocking of all unwanted light from UV up to the IR and the narrow bandwidth of the filters reduces all unwanted signal on the sensor! If you do an exposure of 30sec without any filters from a lightpolluted urban observing site, your sky-background might be allready very, very bright or even saturated. The same image taken with an Narrowband-Emissionline filter will give you a perfect black background without any signal and the signal from the object will be about the same. With this black background you have the possibility to expose longer -propably 30min instead- to record fainter structures!

So the number of for example \"H-alpha-photons\" does not change significant wether a H-alpha filter is installed or not. But looking at the photons of other wavelength, which wi do NOT want to record makes the effect of the filter clear: The combination of a very good blocking of all unwanted light from UV up to the IR and the narrow bandwidth of the filters reduces all unwanted signal on the sensor! If you do an exposure of 30sec without any filters from a lightpolluted urban observing site, your sky-background might be allready very, very bright or even saturated. The same image taken with an Narrowband-Emissionline filter will give you a perfect black background without any signal and the signal from the object will be about the same. With this black background you have the possibility to expose longer -propably 30min instead- to record fainter structures!

Amateurs from all over the world can take images which were far beyond reach even for the very best equiped professional observatories 20 years ago.\u003cbr\u003eYou will need a low noise video-camera and dedicated image-processing like AstroStakkert, Registax or AviStack plus a infrared-pass filter to enter this field of astrophotography!\u003cbr\u003eWhy Infrared? Every observer knows the flickering stars and planetary disks when looking through an eyepiece or at your monitor Slight differences in temperature and preasure 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 wavlengths), 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 changeing 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. The sharpness and high contrast resulted in the best final images in nearly all situations!\u003cbr\u003e\u003cbr\u003e\u003cimg width=\"400px\" src=\"https:\/\/www.astronomik.com\/media\/wysiwyg\/gallery\/Jupiter_Michael_Karrer.JPG\" alt=\"\"\u003e\u003cbr\u003e\u003cstrong\u003eJupiter with Ganymed\u003c\/strong\u003e\u003cbr\u003e(c) Karl Thurner\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cimg width=\"400px\" src=\"https:\/\/www.astronomik.com\/media\/wysiwyg\/gallery\/Luethen_Jupiter_IRRGB.jpg\" alt=\"\"\u003e\u003cbr\u003e\u003cstrong\u003eJupiter With Ganymed\u003c\/strong\u003e\u003cbr\u003e(c) Hartwig Luethen\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eDo you use the AstronomikProPlanet 642 BP for lunar and planetary imaging?

With the Astronomik ProPlanet 642 BP installed in your camera, it´s possible to do nice shoots of H-alpha regions even when the moon is up: Lunar stray light is filtered out very effective!\u003cbr\u003e\u003cbr\u003e\"How long do I have to expose longer?\" -That´s a very common question from custmers from all over the world.\u003cbr\u003eThe answer is quite easy: You don´t have to expose longer, you MAY expose longer!\u003cbr\u003e\u003cbr\u003eDue to the high transmission of nearly 100% you will have the same amound of photons with a wavelength of 656nm on your sensor, wether you have the filter installed or not. But, with the Astronomik ProPlanet 642 BP installed, the background sky will be very dark, while it would be very bright -or even saturated- when imaging without the filter! The filter blocks photons with other energies and give you a higher contrast. With the filter installed you MAY expose longer to collect more photons from your object of desire till the background is getting brighter again!\u003cbr\u003e\u003cbr\u003eA narrow band emission-line filter like the Astronomik H-alpha filter with 12nm or 6nm FWHM will do the job much better (it blocks more of the unwanted light), but the lower price of the Astronomik ProPlanet 642 BP is very attractive for beginners in this field of astrophotography!
