{"title":"Visual Filters for Telescopes","description":"\u003cp\u003eVisual filters for telescopes are essential accessories for astronomers looking to improve the quality of their observations. Designed to modify the light entering the telescope, these filters increase contrast, bring out details on planets, and highlight certain features of deep-sky objects, such as nebulae and galaxies.\u003c\/p\u003e\n\u003cp\u003eUsed by both amateur visual astronomers and experienced observers, visual filters help reduce the effects of light pollution, balance brightness, and enhance the natural colors of celestial objects. They come in various tints and densities, each suited for a specific purpose, whether it’s enhancing the view of lunar craters, Jupiter’s bands, or fine structures in nebulae.\u003c\/p\u003e\n\u003cp\u003eAt Astronomy Plus, we offer a range of reliable, high-performance visual filters for telescopes that are easy to install and compatible with most telescope models.

Based on the popular Baader Moon \u0026amp; Skyglow filter, the Baader Contrast-Booster takes contrast enhancement and skyglow reduction to the maximum level possible from a filter. Not only does this filter deliver a significant enhancement of planetary and lunar contrasts, but it is designed to also totally eliminate the damaging blue defocused haze present in achromatic refractors. Gone are the annoying blue halo and obscuring haze that surround and smear resolution and contrast. Subtle contrasts and colors are boosted, while displaying the full resolution your scope is capable of.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe Contrast-Booster combines a special proprietary melt of Neodymium glass with a carefully designed 23 layer dielectric long-pass blocker on one face, and a 7-layer ultra-low antireflection coating on the other face. By aggressively filtering out the defocused blue wavelengths, a light yellow tint is imparted to objects (noticeably less than a typical yellow filter). The special coatings enable over 95% transmission across key portions of the visible spectrum (including H-Alpha). This results in a filter that retains the colors and color contrasts in tough subjects like Jupiter, without excessive image dimming. Cloud bands retain their ruddy red hues, but now become more striking in contrast. The Great Red Spot finally becomes easier. Planets and Lunarscapes are set against a jet black sky. The Contrast-Booster is a must for Solar observing (with Baader Astro Solar).\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eAs many users have found, this is a great filter for Mars! The views of Mars with all telescopes (including reflectors and apochromats) benefit from the RGB filtration plus blue blocking.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eCombined with the Baader UV-IR-Cut Filter, the Contrast-Booster makes the ideal filter set for digital imaging. Rather than add the cost of additional IR filtration (only needed for digital imaging), the Baader Contrast Booster has been optimized for visual use. Digital imagers can simply add our Baader UV-IR-Cut Filter when needed. The true 1\/4 wave fineoptically polished surfaces guarantee the sharpness and contrast of the image. Filters are available in both 1¼” and 2\" sizes. The base substrate is a special custom melt of Neodymium doped glass, designed for specific transmission characteristics, and made only for Baader Planetarium. In addition to it's unique spectral characteristics, the Contrast-Booster offers Baader's hallmark optical and mechanical features that set it apart and result in the best possible image sharpness, contrast, and real-world durability;\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\"The contrast booster filter certainly removes the violet glow from my 6\" f\/8 refractor both on the bright stars and the moon. It does give a \"warm\" yellow tint to both. I soon got used to this when observing the moon and it posed no problem. I tried it on Mars. Unfortunately I am too far north(+53deg) to escape the worst effects of the earths atmosphere and seeing varied from fair to terrible. Still, it did make the dark markings more clearly visible. The quality of the glass is superb. Some other filters I have used cause a softening of the detail; not so with the Baader. All in all a very worthwhile addition to my observing tools; and at a great price too.\" \u003cem\u003ePat Abbott\u003c\/em\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\"Just wanted to let you know that the Baader Contrast Booster Filter is a GREAT product. Far and away the single best filter that I have used on Mars. I'm looking forward to Jupiter and Saturn. It also really helped with my webcam imaging of Mars.\" \u003cem\u003e\u003cspan style=\"text-decoration: underline;\"\u003eGordon Dayton\u003c\/span\u003e\u003c\/em\u003e\u003cbr\u003e\n\u003cdiv data-pdp-tab-content=\"description\" class=\"pdp-content-description rte active\"\u003e\n\u003ch3 data-pdp-tab-content=\"description\" class=\"pdp-content-description rte active\"\u003e\u003c\/h3\u003e\n\u003ch3 data-pdp-tab-content=\"description\" class=\"pdp-content-description rte active\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ch2 style=\"box-sizing: inherit;

It aids in better detection of Venus phase. With this filter, the Violet Clearing on Mars can be seen better. It also enhances the Great Red Spot on Jupiter, the contrast between the belts and enhances the contrast between zones on Saturn.\n\u003ch4\u003eColor filters for increased contrast of lunar and planetary observations\u003c\/h4\u003e\n\u003cp\u003eThe Baader color filters are carefully prepared for amateur astronomical interests. The glass are coplaner fine optically polished. These filters exceed the quality of the usual \"raw polished\" (hot flamed) colored glass filters. Because they are fine optically polished, these filters can be at any point in the mean path - far ahead of the focal point (for example, in front of a binocular approach!) without causing defects (astigmastism) or to degrade the image otherwise in any way! The parallelisn of the optical surfaces is excellent with 30 arcseconds. Double images are absolutely excluded. For each filter colour, the transmission curve is supplied as a measurement protocol. Color filters are often identified with a Kodak Wratten number (W-point). Baader color filters were collected by astronomical experience and correspond to the respective wavelength range following filter by Wratten nomenclature: \u003cstrong\u003eBaader-red filter ≅ W25, Baader-Orange filter ≅ W21, Baader-yellow filter≅ W12, Baader-green filter≅ W58, Baader-light blue filter ≅ W80A, Baader-dark blue filter≅ W38A\u003c\/strong\u003e These filters are screwed into the filter thread of eyepieces or planetary imaging cams (Skyris). A thread at either end of the filter allows the filters to be combined with each other or with other filters (for example with a Baader UV \/ IR infrared cut filter).  Transmission curves of 6 Baader color filters (dark blue, light blue, green, yellow, orange and red)\u003c\/p\u003e\n\u003ch4\u003eFeatures\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eLargest free opening of all colour filters on the market to elimante any vignetting.\u003c\/li\u003e\n\u003cli\u003eCNC machined \"grip crown\" provides excellent handling and comfort.\u003c\/li\u003e\n\u003cli\u003eBoth sides 7-layer AR coating with only 0.25% residual reflection per surface. This is the most antireflective that has ever been undertaken with color filters.\u003c\/li\u003e\n\u003cli\u003eThe most important criterion for any kind of light filtering is brigthness. Certain spectral ranges at high magnification will only work at the highest light transmittance.\u003c\/li\u003e\n\u003cli\u003eThe long-pass filter in this filter set offers 98% transmission and produces no flare. Unmatched by other brands. This can be seen in comparison with standard colour filters at once - the filter colour radiant downright.\u003c\/li\u003e\n\u003cli\u003eThe combination of our infraread (IR) cut filter 1¼\" and the RG 610 red filter results as an extremely narrow-band H-α pass filter for the CCD photography of red emission nebulae - at a ridcidulously low price!\u003c\/li\u003e\n\u003cli\u003eA wide range of adaptors allow the uses of T-2 photo threads (See: Baader Astro T-2 System™).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eBaader Phantom Group Coating™\u003c\/h4\u003e\n\u003cp\u003eDeveloped by Baader Planetarium the coating is a 7-layer broadband coating with extremely low residual reflection. The term \"Group\" indicates that the respective most effective anti-reflection layer system was calculated for each type of glass of the filter. This means that the anti-reflection layers of different colour filters are different. They are calculated to provide the mximum for the respective filtered colour transmission values. Both sides of the filter are coated with 7-layer AR coating with only 0.25% residual reflection per surface. This is the most that has ever been provided for colour filters. The filter discs are screwed into the blackened aluminium frames and are delivered within a filter.

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.

It lets the light of the H-beta emission line pass nearly unhindered and blocks the remaining spectral range to the extent that the eye is dark adapted. By the use of the Astronomik H-beta filter, the contrast is increased so strongly, that even the observation of the Horse Head Nebulae with telescopes of 10\" - 12\" reaches the realm of the possible.\n\u003ch4\u003e\u003cstrong\u003eMain use\u003c\/strong\u003e\u003c\/h4\u003e\nThe optimal aperture ratio for the use of the filter is 1:4,5 to 1:6. The range of application extends from 1:3.5 to 1:15. Transmission losses and chromatic distortions, which arise with other filters, are only apparent with the Astronomik filters when extremely fast aperture ratios of 1:3 and higher are used. The Astronomik H-beta filter will allow you to view large objects, in the whole field of view of the eyepiece, even when using wide-angle eyepieces - not only in the center of the eyepiece. 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. Due to the high optical quality of the Astronomik H-beta filter substrate you will see the same needle-sharp stars as you would from your regular telescope.\n\u003ch4\u003e\u003cstrong\u003eOther uses\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eIn the whole sky, there are few objects that benefit from the use of this filter in visual observation.

More important is the significantly better blocking aside of the O-III wavelength, as well as even steeper transmission slopes and a broad plateau in the transmission range. With a transmission of 97% for the emission line at 500.7 nm, practically all the light of the nebula passes through the filter. At the same time, this filter can be used photographically for practically any focal ratio from f\/1.8 to f\/12 without passing any light of the H-beta line. This makes the Super-G filter just as ideal for use in areas with high light pollution.\u003c\/p\u003e\n\u003ch2\u003ePhotographic use\u003c\/h2\u003e\n\u003cp\u003eThe 9 nm O-III filter can be excellently used photographically on all telescopes, especially with a DSLR or an astronomical OSC colour camera. It offers all the advantages of the CMOS-optimized Baader filters such as Reflex-Blocker™ coating against reflections, plano-optical polishing and age-resistant Life-Coat™ coating. For monochrome cameras, we recommend the even stronger Narrowband (6,5 nm) and Ultra-Narrowband (4 nm) filters , which are available specially adapted for different aperture ratios. For this comparatively broadband 9 nm filter, pre-shifting is not necessary at focal ratios faster than f\/4, thus it can be used at all focal ratios.\u003c\/p\u003e\n\u003ch2\u003eSuper-G filter\u003c\/h2\u003e\n\u003cp\u003eThe filter has the same thickness as the 1.25\"\/2\" Baader LRGB filters.

The filter allows only the light from the two carbon bands to pass through and, among other things, blocks the ubiquitous stray light, similar to a nebula filter in deep-sky observation. Structures in the gas tail thus become clearer even under good observing conditions. At the same time, it completely blocks the OIII line at 501nm and below, which other Swan-Band filters allow to pass. This allows for even higher contrast, and comets with gas tails can be distinguished even better from those dominated by a dust tail (and where a SWAN filter provides only a small contrast enhancement).
