We would not offer both series if they were not needed.\u003cbr data-mce-fragment=\"1\"\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!

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!

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 data-mce-fragment=\"1\"\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 data-mce-fragment=\"1\"\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 data-mce-fragment=\"1\"\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.

bandpass light pollution suppression filter for colour cameras. It effectively suppresses the transmission of light pollution wavelengths, especially light pollution generated by artificial lighting (including mercury and sodium lamps), as well as the effects of natural skylight-induced effects on the shot, thus effectively enhancing the contrast and details of the celestial bodies, and making the objects more distinct and stereoscopic. This filter provides better color balance while improving resistance of light pollution. L-QEF can be used for both wide field astrophotography, such as the Milky Way in Summer and Winter, and deep sky objects such as nebulae, galaxies, star clusters, and so forth; It allows you to save a lot of time during the shooting process and get better results at the same time. The design of quad bandpass maximises the colour balance of nebulae, galaxies and other broadband spectral targets.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCuts out light pollution from mercury and sodium lamps and produces a nice broadband image with minimal colour cast;\u003c\/li\u003e\n\u003cli\u003eSignal-to-noise ratio (SNR);\u003c\/li\u003e\n\u003cli\u003eNear IR cut-off to 1000nm, reducing the effects of IR noise;\u003c\/li\u003e\n\u003cli\u003eL-QEF has more than 90% transmittance of the nebula emission lines at H-Beta\/OIII\/H-Alpha\/SII, with cut-off depth from OD2 to OD4, thus providing a significant increase in resistance to light pollution.

This specially-optimized version will provide significantly SNR(Signal to Noise Ratio) for the fast telescopes with focal ratio between f\/2.6 and f\/3.6 than the standard 3nm Pro version.\u003cbr\u003e\u003cbr\u003eThe optical light path of a telescope is cone-shaped, which creates an angle, and the center wavelength of the interference filter will shift toward shorter (blue) wavelengths as the angle of incidence((AOI) increases; the greater the angle， the greater the shift. The amount of beam deviation depends on the refractive index and the thickness of the substrate. The blue shift data by the simulation indicates that at a focal ratio of f\/2.6, the angle of incidence of the light cone is 10°and its bandwidth shift 2.2nm to shorter wavelengths. Therefore, the Highspeed 3nm Pro narrowband filters are designed to be pre-shifted by 1.2nm towards the longer (red) end in order to compensate for the Blueshift and ensure high signal acquisition by telescopes with fast focal ratios.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications \u003cbr\u003e\n\u003c\/h3\u003e\n\u003ctable data-mce-fragment=\"1\" style=\"text-size-adjust: 100%;

This filter furthermore enhances the contrast of the continuous spectrum lights from comet dust tails, galaxies and the Milky Way by making use of the NIR region that is hardly interferenced by light pollutions.

This is because the anti-reflection properties of off-the-shelf cameras' optical systems (oiptical window and sensor cover glass) are optimized for the visible spectrum only, not for the NIR region. Thus, haoling at the camera end in the unoptimized region becomes more apparent, coupled with haloing from the filter itself.\u003cbr\u003eHere is a rough estimation of the magnitude of haoling where

Emission nebulae primarily emit at discrete wavelengths of light—Hα at 656nm, Hβ at 486nm, and OIII at 496\/501nm. By strategically transmitting only these wavelengths of light and blocking the rest of the spectrum, the filter dramatically reduces the effect of light pollution. The “bad” light is blocked while the “good” light associated with emission nebulae passes through to Origin’s sensor.\u003c\/p\u003e\n\u003cp\u003eYou’ll immediately notice much higher contrast in your images, especially from your light-polluted backyard! And since the transmission at the critical wavelengths is so high, the nebula will not be dimmed—only the background will be blacker. You’ll also notice some contrast improvement in images of nebulae from darker skies, as the filter serves well in blocking natural skyglow.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNebula Hunting\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Nebula Filter is perfect for imaging emission nebulae like the North America Nebula (NGC 7000), Lagoon Nebula (M8), Orion Nebula (M42), the Carina Nebula (NGC 3372), and dozens more. The imaging filter offers maximum light transmission in the key Hα-Hβ-OIII wavelengths, producing high contrast for emission nebulae like these.\u003c\/p\u003e\n\u003cp\u003eThe transmission spectrum for the Nebula Filter is 85% or greater at key wavelengths (486nm, 496nm\/501nm, 656nm) and less than 0.5% transmission elsewhere. As a narrowband filter, it blocks much of the visible spectrum and only lets these specific wavelengths through. Because of this, you should not use this filter while observing or imaging broadband emission objects, such as galaxies and star clusters. For those objects, you’ll achieve the best results by removing the nebula filter and reinstalling Origin’s clear optical window.\u003c\/p\u003e\n\u003cp\u003e\u003cimg height=\"641\" width=\"834\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/1_caab78ba-5427-4eee-819c-6d24c0267e43.png?v=1716578248\" alt=\"\" data-mce-src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/1_caab78ba-5427-4eee-819c-6d24c0267e43.png?v=1716578248\u0026amp;width=700\"\u003e\u003c\/p\u003e\n\u003cp\u003eOther similar imaging filters on the market have much narrower bandpasses at the critical Hα-Hβ-OIII wavelengths. Unfortunately, these filters block much of the incoming Hα-Hβ-OIII light for an f\/2.2 optical system like Origin’s 6” RASA. This is because a RASA brings light into the filter at a steeper angle, which causes a spectral shift. If you use filters not explicitly designed for use at f\/2.2, some of the light from the nebula will be blocked, resulting in a dimmer image. The Nebula Filter for Origin was custom-engineered to work at f\/2.2, so none of the “good” light from the nebula is inadvertently blocked by the filter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBody and Storage\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe filter features a machined aluminum black anodized cell with a knurled rim for easy grip during installation.  We’ve added anti-reflection coatings to help suppress reflections from the glass. The filter fits directly into the filter drawer in the Celestron Origin’s front lens cell, where the optical window sits. Simply remove the clear window and replace it with the filter. Origin maintains its optical performance with the filter installed. No other adapter is needed.\u003c\/p\u003e\n\u003cp\u003eEach filter comes with a foam-lined plastic storage case to safely store the filter or the optical window that came with your Celestron Origin when not in use.\u003c\/p\u003e\n\u003cp\u003eCelestron tests every Nebula Filter for Origin individually to verify its performance. Along with your filter, you will receive a spectral transmission graph (like the one pictured above) showing the results of your filter’s test and verifying it performs as expected throughout the spectrum.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications \u003c\/h3\u003e\n\u003ctable border=\"0\" cellspacing=\"0\"\u003e\n\u003ccolgroup width=\"156\" span=\"2\"\u003e\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd valign=\"middle\" align=\"center\" height=\"18\"\u003e\u003cspan style=\"color: #000000;\"\u003eGlass type:\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd valign=\"middle\" align=\"center\"\u003e\u003cspan style=\"color: #000000;\"\u003eSchott B270\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"middle\" align=\"center\" height=\"18\"\u003e\u003cspan style=\"color: #000000;\"\u003eGlass thickness:\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd valign=\"middle\" align=\"center\"\u003e\u003cspan style=\"color: #000000;\"\u003e2mm (0.078\")\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"middle\" align=\"center\" height=\"18\"\u003e\u003cspan style=\"color: #000000;\"\u003eClear aperture:\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd valign=\"middle\" align=\"center\"\u003e\u003cspan style=\"color: #000000;\"\u003e24mm (0.94\")\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"middle\" align=\"center\" height=\"47\"\u003e\u003cspan style=\"color: #000000;\"\u003eCoatings:\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd valign=\"middle\" align=\"center\"\u003e\u003cspan style=\"color: #000000;\"\u003eDichroic multi-bandpass and multi-layer anti-reflection coatings\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"middle\" align=\"center\" height=\"32\"\u003e\u003cspan style=\"color: #000000;\"\u003eFilter cell:\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd valign=\"middle\" align=\"center\"\u003e\u003cspan style=\"color: #000000;\"\u003eAluminum, black anodized\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"middle\" align=\"center\" height=\"47\"\u003e\u003cspan style=\"color: #000000;\"\u003eFilter threads:\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd valign=\"middle\" align=\"center\"\u003e\u003cspan style=\"color: #000000;\"\u003eM28.5 x 0.6, fits standard 1.25\" filter threads\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"middle\" align=\"center\" height=\"47\"\u003e\u003cspan style=\"color: #000000;\"\u003eHeight of cell:\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd valign=\"middle\" align=\"center\"\u003e\u003cspan style=\"color: #000000;\"\u003e6mm total (4mm shoulder height, 2mm thread height)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNebula Filter for Origin Intelligent Home Observatory (93669)\u003c\/li\u003e\n\u003cli\u003eProtective Case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWarranty \u0026amp; Manuals\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\nHα-Hβ-OIII Imaging Filter, RASA 8 instruction sheet\u003cspan style=\"font-size: 0.875rem;\" data-mce-style=\"font-size: 0.875rem;\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eNebula Filter for Origin Manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e2-Year Warranty\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c!----\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":52184008753381,"sku":"tha1787937582660","price":132.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/4561\/8405\/files\/celestron-nebula-filter-for-origin-intelligent-home-observatory-93669_1.png?v=1787937586"},{"product_id":"baader-solar-continuum-filter-75nm-540nm","title":"Baader Solar Continuum Filter 7.5nm (540nm)","description":"\u003ch2 class=\"product-title\"\u003eBaader Solar Continuum Filter 7.5nm (540nm)\u003c\/h2\u003e\n\u003cp\u003eFor Visual and Photographic Observations of the Sun\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBaader 7.5 nm Solar Continuum Filter, CWL 540nm\u003c\/li\u003e\n\u003cli\u003eA must for owners of achromatic refractors.

The filter works as a monochromator: suppressing the effects of the atmospheric turbulence and delivering images that are significantly sharper.\u003c\/p\u003e\n\u003cp\u003eLens systems - including those of apochromats, catadioptrics, or eyepieces - are traditionally optimized for the spectral range around 540nm, since this is where our eye has the highest sensitivity. This narrowband filter therefore blocks everything with the exception of the spectral range in which a lens optic works most sharply and with the highest contrast. The effect is greatest on achromatic lens telescopes; but there is also an effect on apochromatic telescopes, catadioptric systems, and even pure mirror systems by reducing air turbulence.\u003c\/p\u003e\n\u003cp\u003eAs a\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003emonochromatic filter, it is ideal for use on monochromatic cameras\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eand can even provide a tremendous gain on pure color systems.\u003c\/p\u003e\n\u003cp\u003e\u003cimg height=\"750\" width=\"578\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0267\/1172\/0013\/files\/01-ND09.jpg?v=1667762944\u0026amp;width=700\"\u003e\u003c\/p\u003e\n\u003cp\u003eWith a color camera, as with deep-sky narrow-band photography, it is less effective as only the green pixels are used.
