Les utilisateurs visuels ont rapporté d'excellents résultats même jusqu'à f\/3.5. Les optiques sont recouvertes d'un revêtement antireflet avec les multicouches du groupe PHantom de Baader. Le MPCC est également à un prix très raisonnable. Sa modularité vous permet d'acheter uniquement les pièces dont vous avez besoin. Pour l'imagerie avec des reflex numériques, seul le MPCC est requis (pour la taille de champ maximale, le MPCC MkIII est conçu pour fonctionner parfaitement avec les anneaux en T Baader Protective EOS).

Le MPCC peut être configuré à peu de frais pour une utilisation visuelle avec des oculaires de 1¼\" et 2\". Veuillez consulter notre page de configuration visuelle MPCC pour de nouvelles informations sur certaines configurations visuelles intéressantes.\u003c\/p\u003e \u003cp\u003eAucune augmentation de grossissement : le MPCC fournit des champs complets pour les oculaires les plus larges de 5,1 cm. Pourquoi dépenser le gros $$ sur un grand oculaire à grand champ, seulement pour avoir son champ pressé par le correcteur de coma. Maintenant, un oculaire ultra grand champ de 31 mm peut fonctionner comme un 31 mm et non un 26 mm. De plus, contrairement à certains correcteurs, le MPCC a un effet minimal sur le point oculaire et le comportement d'occultation des oculaires à longue focale.\u003c\/p\u003e\n\u003cp\u003e Aucun back-focus supplémentaire (en course) requis : en fait, dans les configurations à couplage direct, le MPCC augmente en fait le back-focus d'environ 10 mm. Si votre oculaire fera la mise au point sans correcteur de coma, il atteindra la mise au point avec le MPCC. Ce n'est pas le cas avec certains autres correcteurs de coma.\u003c\/p\u003e\n\u003cp\u003e Vignettage réduit : le nouveau MPCC MkIII fonctionne désormais encore mieux avec les plus grands oculaires à champ réel de 2\". En raison de la position plus proche de la lentille de champ par rapport au plan focal, le MPCC MkIII est capable de fournir un champ réel entièrement éclairé plus grand que tout autre coma correcteurs (à la fois visuels et photographiques)\u003c\/p\u003e \u003cp\u003eFaible coût : Le MPCC est moins cher que les autres correcteurs. Certains utilisateurs en ont même acheté plusieurs et les laissent attachés en permanence à leurs oculaires 2\" préférés.\u003c\/p\u003e\n\u003ch4\u003e IMAGERIE\u003c\/h4\u003e\n\u003cp\u003e Le MPCC est parfaitement adapté aux reflex numériques d'aujourd'hui. Les propriétaires de ces nouveaux appareils photo trouvent qu'ils sont idéalement associés aux newtoniens f\/3,5-f\/5 rapides d'aujourd'hui nécessaires pour maintenir des expositions courtes. Le MPCC permet à ces utilisateurs de corriger entièrement leurs portées et de produire de superbes images du ciel profond en couleur sans la complexité des astrocaméras CCD plus coûteuses. Les propriétaires de Vixen Newtonians apprécieront l'inclusion de fils de filtre et la grande netteté des images. Contrairement aux autres correcteurs de coma, le MPCC n'étend PAS le rapport focal (ainsi, vos images seront prises à la pleine vitesse de votre télescope).\u003c\/p\u003e \u003cp\u003eLe MPCC s'insère dans des porte-oculaires de 2\" et possède des filetages en T externes du côté de la sortie (et est également fileté pour les filtres standard de 2\"\/48 mm). Fixez simplement n'importe quel film 35 mm ou reflex numérique au MPCC, à l'aide d'adaptateurs en T couramment disponibles. Les utilisateurs de caméras CCD peuvent se fixer de la même manière grâce à l'utilisation de nos composants du système Astro T-2 (adaptateurs, tubes d'extension). Le MPCC est conçu pour une distance nominale de 55 mm entre la bride de montage et le plan du film (55 mm est la dimension standard pour tous les reflex, mesurée de l'avant de leur adaptateur en T à leur plan d'image). Il étend également le point de mise au point d'environ 10 mm, de sorte qu'aucune mise au point supplémentaire n'est nécessaire pour utiliser le MPCC (bien sûr, cela suppose que votre appareil photo atteindra déjà la mise au point dans votre télescope, sans le MPCC).\u003c\/p\u003e\n\u003cp\u003e Le MPCC comprend également une bride d'arrêt amovible. Le retrait de cette bride expose un filetage externe M48, qui permet au MPCC d'être directement couplé aux oculaires de 2\" et inséré entièrement à l'intérieur des porte-oculaires de 2\".

Sensors\u003c\/h2\u003e\n\u003cp\u003eThe Tele Vue Big Paracorr Type 2 is a specialized optical corrector designed to solve one fundamental problem: the comatic aberration inherent in fast Newtonian reflectors. For astro-imagers using large sensors or visual observers with ultra-wide eyepieces, this device transforms distorted, comet-shaped stars at the edge of the field into sharp, round pinpoints, effectively making your mirror's full potential visible from corner to corner.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe Physics of a Flawless Field\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the Big Paracorr is a multi-element, high-index glass optical system engineered to counteract the physics of a parabolic mirror. Mirrors faster than f\/6 naturally produce coma, an aberration that elongates stars as you move away from the central axis. The Paracorr's lenses introduce an equal but opposite correction, ensuring light rays from across the entire field come to a sharp, symmetrical focus on your camera sensor or at the eyepiece.\u003c\/p\u003e\n\u003cp\u003eThe visual result is a radical improvement in edge-of-field performance. On a full-frame image of a dense star field like the Perseus Double Cluster, stars that would appear as distracting seagulls or crescents become tight, point-like sources. This allows you to use the entire frame for your composition, no longer needing to crop away the distorted outer third of your images.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eEngineered for Large-Format Illumination\u003c\/h3\u003e\n\u003cp\u003eThe \"Big\" in Big Paracorr is a direct reference to its 3-inch barrel format. This larger diameter is not for vanity; it is a mechanical necessity for illuminating sensors with diagonals of 43mm (full-frame) or larger without vignetting. A standard 2-inch corrector would cause the image brightness to fall off dramatically in the corners of a large sensor, but the Big Paracorr's wide body and oversized lenses provide an even, un-clipped light cone.\u003c\/p\u003e\n\u003cp\u003eThis makes it the right choice for imagers who have invested in full-frame DSLR, mirrorless, or dedicated astronomy cameras. It ensures that your flat frames are correcting for minor dust and gradients, not for a fundamental vignetting issue caused by an undersized corrector. The result is higher signal-to-noise in the corners and a more uniform final image.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eDialing in Perfection with the Tunable Top\u003c\/h3\u003e\n\u003cp\u003eOptimal coma correction depends on the precise distance between the Paracorr's lenses and the focal plane. The Big Paracorr's \"Tunable Top\" is a calibrated, adjustable mechanism that lets you dial in this exact distance for your specific eyepiece or camera. By simply loosening a collar and rotating the top, you can match the setting to your equipment, ensuring the best possible correction.\u003c\/p\u003e\n\u003cp\u003eThis eliminates guesswork and provides a repeatable, optimized setup. For an imager, it means you can set the back focus correctly for your specific camera and filter wheel combination. For a visual observer switching between different eyepieces, it allows for quick tweaks to maintain edge-to-edge sharpness across your entire collection.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eMore Than a Corrector: The 1.15x Magnification Factor\u003c\/h3\u003e\n\u003cp\u003eThe Paracorr's design includes a slight 1.15x magnification factor. This is an integral part of how the 4-element lens system achieves its correction and should not be mistaken for a simple Barlow effect. This minor focal length increase has a secondary benefit: it slightly darkens the sky background, which can increase the contrast on faint, extended objects like galaxies and nebulae.\u003c\/p\u003e\n\u003cp\u003eThis also means your f\/4 mirror performs like an f\/4.6 system, which can make collimation slightly more forgiving. It’s a subtle but meaningful characteristic that contributes to the overall quality of the final view or image, turning your fast, wide-field instrument into a perfectly corrected, high-contrast system.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSecure Connections for Heavy Payloads\u003c\/h3\u003e\n\u003cp\u003eRecognizing that large-format imaging involves heavy camera trains, the Big Paracorr uses threaded connections instead of simple compression rings. The back of the unit provides a 3.40\" x 24 TPI flange for attaching robust, dedicated camera adapters. This prevents any tilt or flexure that could compromise the optical correction, a critical factor when dealing with the tight tolerances of a fast optical system.\u003c\/p\u003e\n\u003cp\u003eThe primary limitation of the Big Paracorr is its requirement for a robust, 3-inch focuser and a mount capable of handling the entire imaging payload.

Corrector is engineered to eliminate coma in fast Newtonian astrographs, transforming the native curved focal plane of a parabolic mirror into a wide, flat, and exceptionally well-corrected field for large-format imaging sensors. Its advanced optical formula, comprising four lenses made from special rare earth glass types, delivers sharp, apochromatic stars from edge to edge. This corrector is the key to unlocking the full imaging potential of high-accuracy parabolic mirrors, ensuring that the final image is limited only by the primary optic and the seeing conditions, not the corrector.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eAdvanced Wynne Corrector: A Wide, Flat, Apochromatic Field\u003c\/h3\u003e\n\u003cp\u003eThis corrector's primary function is to create a professional-grade imaging platform from a fast Newtonian optical system.
