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.

Thanks to the high-precision machining of the glas substrate, all Astronomik filters are parfocal. The wedge errors are far below all common tolerances. Therefore, all issues concerning focal distances and the exact alignment of images from each color channel are effectively eliminated.\u003c\/p\u003e\n\u003cp\u003eAll Astronomik filters are ideal for modern cameras, including both CMOS- and CCD-based models, ensuring you capture the best possible images with your equipment. Sharpness, contrast, and the absence of any reflections and halos are guaranteed. Even with bright stars in the field of view, nebulae and galaxies will be captured with the finest structures. The Astronomik MFR and MaxFR coatings are designed for optimal performance across a wide range of focal ratios of the optics used.\u003c\/p\u003e\n\u003cp\u003eEvery Astronomik filter undergoes a rigorous quality control process before delivery. Additionally, each Astronomik Narrowband-Emissionline filter is measured using a high-end PerkinElmer Spectrophotometer to ensure it meets the specifications published on our website. On the back of each Narrowband-Emissionline filter box, you will find a label detailing the precise spectral data for that specific filter, including the maximum transmission and the recommended range of focal ratios for best performance of that specific filter.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTypical transmission of 95% at 486nm (H-beta)\u003c\/li\u003e\n\u003cli\u003eTypical transmission of 95% at 496nm and 501nm (OIII)\u003c\/li\u003e\n\u003cli\u003eTypical transmission of 95% at 656nm (H alpha)\u003c\/li\u003e\n\u003cli\u003eTransmission range: 480nm to 505nm and above 645nm \u003c\/li\u003e\n\u003cli\u003eFull-Width-Half Maximum (FWHM): 25nm\u003c\/li\u003e\n\u003cli\u003eGlass thickness: 1mm (except Astronomik OWB Type 3 and XT filters)\u003c\/li\u003e\n\u003cli\u003eFinely polished optical glass, free of any striae, residual stresses, and bubbles\u003c\/li\u003e\n\u003cli\u003eExtremely scratch-resistant and durable coating\u003c\/li\u003e\n\u003cli\u003eCompletely resistant against high humidity and aging effects\u003c\/li\u003e\n\u003cli\u003eParfocal with other Astronomik filters\u003c\/li\u003e\n\u003cli\u003eDiffraction-limited\u003c\/li\u003e\n\u003cli\u003eOptimized spectral windows\u003c\/li\u003e\n\u003cli\u003eDelivered in a high-quality, long-lasting filter box\u003c\/li\u003e\n\u003cli\u003eMade in Germany\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSelected frame size Astronomik UHC Filter\u003c\/li\u003e\n\u003cli\u003ePlastic Storage Case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 role=\"tabpanel\" aria-hidden=\"false\" aria-labelledby=\"tab-title-3\" data-content=\"tab-3\" class=\"tab__content tab.box tab__content--active\"\u003e\n\u003cspan\u003eManual \u0026amp;
