L'ouverture de 103 mm lui confère un avantage inhérent en termes de puissance de collecte de lumière, de résolution, de luminosité et de contraste, permettant au photographe de collecter plus de lumière et de présenter plus de détails et d'objets plus lumineux dans l'image.\n\u003cbr\u003e\n Askar 103APO adopte une conception de lentille APO triple à espacement d'air, comprenant une pièce de verre ED.\n\u003cbr\u003e \nLe télescope APO (apochromatique) est un type de télescope capable de corriger l'aberration chromatique. L'aberration chromatique est une aberration optique courante qui provoque des bords colorés ou un flou autour des bords des objets dans une image. D'autres télescopes ont des conceptions optiques relativement simples et sont sujets à l'aberration chromatique, en particulier à fort grossissement ou dans les observations où la précision des couleurs est requise. Cependant, les télescopes APO utilisent des conceptions optiques spéciales et plusieurs éléments de lentilles pour corriger l'aberration chromatique, offrant ainsi naturellement des détails d'objet et une précision des couleurs de meilleure qualité.\n\u003cbr\u003e\n Dans la structure des éléments du réfracteur, l'augmentation du nombre d'éléments de lentille et la conception de combinaisons de lentilles peuvent améliorer efficacement la correction de l'aberration chromatique. Cependant, cela signifie également une augmentation des coûts de production et une complexité de conception.\n\u003cbr\u003e \nLe verre ED, également connu sous le nom de verre à faible dispersion, est un type de verre optique spécialement conçu pour réduire l'aberration chromatique. L'aberration chromatique se produit parce que la lumière de différentes longueurs d'onde se réfracte différemment lorsqu'elle traverse une lentille, entraînant une séparation des couleurs et une diminution de la qualité de l'image. Le verre ED possède des propriétés optiques spéciales qui aident à réduire la lumière parasite et à minimiser efficacement l'aberration chromatique.\n\u003cbr\u003e\n L'Askar 103APO adopte non seulement une conception de lentille triplet (alors que les astrographes économiques du marché utilisent généralement un doublet), mais il dispose également d'un verre ED pour améliorer encore la qualité de l'image. \n\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv style=\"text-align: start;\" class=\"image-side-2\" data-mce-style=\"text-align: start;\"\u003e\n\n\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/85033ec3-b08b-4cee-80e4-8e5fbe75a031.jpg?v=1722016068\"\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv\u003e\n\n\u003chr\u003e\n\n\u003cdiv class=\"two-columns-section\"\u003e\n\n\u003cdiv style=\"text-align: start;\" class=\"image-side-2\" data-mce-style=\"text-align: start;\"\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/Screenshot_2024-07-26_at_1.43.36_PM.png?v=1722016228\" alt=\"\"\u003e\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"text-side-2\"\u003e\n\n\u003cp\u003e\n En plus de l'objectif soigneusement conçu lui-même, chaque aspect de l'Askar 103APO est dédié à offrir une meilleure expérience de prise de vue aux utilisateurs.\n\u003cbr\u003e \nTout l'intérieur du pare-buée de l'Askar 103APO est recouvert de feutre mat, tandis que les parois intérieures du tube principal sont recouvertes de peinture mat et équipées du déflecteur interne.

Chaque côté du porte-oculaire est équipé d'une base de recherche. De nombreux utilisateurs ont exprimé leurs inquiétudes concernant l'espace limité pour installer des accessoires astronomiques supplémentaires au cours de l'utilisation. Pour résoudre ce problème, nous avons spécialement installé des bases de recherche des deux côtés du porte-oculaire. Cela élimine non seulement le besoin de démontage lors du changement de position du chercheur, mais fournit également des positions de montage supplémentaires pour d'autres accessoires astronomiques.\n\u003cbr\u003e\n La poignée de l'Askar 103APO a une conception de fente spéciale, ce qui en fait également une base pour l'installation d'un chercheur. La poignée elle-même est robuste et durable.\n\u003cbr\u003e\n La conception globale des anneaux tubulaires est légère, avec un poids total de seulement 750 g. La vis moletée de l'anneau du tube permet une ouverture et un verrouillage faciles. En même temps, la base surélevée crée plus d’espace pour accueillir des accessoires astronomiques. Au quotidien, la commodité de chaque étape est prise en compte.\n\u003cbr\u003e \nLa plaque à queue d'aronde est la plaque à queue d'aronde Vixen standard, compatible avec la plupart des montures et bases équatoriales du marché. Nous avons également réalisé des extensions supplémentaires et des conceptions de position des trous, la longueur pouvant atteindre 290 mm, ce qui la rend plus pratique pour l'équilibre sur la monture équatoriale. Grâce à la fente sur la poignée, l'espacement entre l'anneau du tube peut être ajusté à volonté. De plus, il existe également une plaque à queue d'aronde Losmandy disponible à l'achat, à utiliser avec différentes montures équatoriales.\n\u003cbr\u003e\n La conception du tube principal amovible permet à un OTA de réduire le rapport focal de 4 par rapport au F6.8 natif.

dovetail plate. Its air-spaced triplet objective, which includes one element of ED glass, delivers high-contrast, color-pure images across a 44mm image circle, making it a powerful and portable instrument for full-frame astrophotography.\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\u003e120mm f\/7 Triplet APO Optics: Light Gathering and Color Correction\u003c\/h3\u003e\n\u003cp\u003eThe core of the 120APO is its 120mm air-spaced triplet objective. This design leverages an ED (Extra-low Dispersion) glass element to sharply minimize chromatic aberration, ensuring stars are tight, color-fringing is suppressed, and contrast on planetary and deep-sky targets is maximized. At f\/7, the 840mm focal length provides the ideal image scale for resolving details in medium-to-large galaxies and planetary nebulae without demanding perfect seeing conditions.\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 Portability: A 6.5 kg Imaging Platform\u003c\/h3\u003e\n\u003cp\u003eAskar designed the 120APO for field use, keeping the total weight to an impressively low 6.5 kg.

maximum image scale. It establishes a standard 55mm back focus from its M48 male thread and includes M68 and M54 adapters for versatile camera connection, all within a 0.74kg assembly.\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\u003eTriplet Optics: Full-Frame Correction at a Native f\/7\u003c\/h3\u003e\n\u003cp\u003eDesigned specifically for the Askar 185APO, this flattener uses a three-element optical layout to eliminate field curvature and coma across a full-frame sensor.

This spacing is ideal for use with DSLRs, mirrorless cameras, and dedicated astronomy cameras connected to a filter wheel. The unit includes M68×1, M54×0.75, and M48×0.75 adapters, providing robust, threaded connections for a wide range of equipment. A built-in M48×0.75 thread also allows for the direct installation of 2-inch filters.\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\u003e1x Flattener vs. 0.8x Reducer: Imaging at the Native 1295mm Focal Length\u003c\/h3\u003e\n\u003cp\u003eChoosing between this 1x flattener and the optional 0.8x reducer depends entirely on your target.

Reducer\u003c\/h2\u003e\n\u003cp\u003eThe Askar 185APO 0.8x Full-frame Reducer transforms its dedicated telescope into a faster, wider imaging system, shortening the native focal ratio to f\/5.6 and the focal length to 1036mm. Its 4-element quadruplet design corrects for field curvature across a full-frame sensor, while the standard 55mm back focus ensures compatibility with a wide range of cameras and accessories. Weighing just 0.95kg, it provides multiple rear-end threads including M68×1, M54×0.75, and M48×0.75 for direct integration into your imaging train.\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\u003eQuadruplet Optics: Reducing the 185APO to a Fast f\/5.6\u003c\/h3\u003e\n\u003cp\u003eThis reducer is engineered specifically for the Askar 185APO, converting it to a faster f\/5.6 instrument. This reduction in focal ratio significantly cuts required exposure times and expands the field of view, making it ideal for capturing vast emission nebulae like the North American Nebula (NGC 7000) or sprawling star clusters in a single frame. The 4-element quadruplet optical design acts as a field flattener, ensuring stars remain sharp and pinpoint across the entire full-frame image circle without introducing optical aberrations.\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\u003e55mm Back Focus and Flexible Full-Frame Connections\u003c\/h3\u003e\n\u003cp\u003eIntegration with your existing gear is straightforward. The reducer provides a standard 55mm back focus distance measured from the base of its M48 male thread, matching the requirement for DSLRs with a T-ring and many cooled astronomy cameras when used with a filter wheel. For maximum flexibility, the reducer includes M68×1, M54×0.75, and M48×0.75 adapters on the camera side. It also features an internal M48×0.75 thread, allowing you to mount standard 2-inch filters directly inside the reducer body, simplifying your optical train and maintaining correct spacing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the main benefit of using the 0.8x reducer with the Askar 185APO?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe primary benefit is speed. By reducing the focal ratio to f\/5.6, you can gather the same amount of light in a significantly shorter time compared to the telescope's native f\/7. This allows for higher quality images with less total exposure time and reduces demands on your mount's tracking accuracy. It also provides a wider field of view for imaging large celestial objects.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow does the Askar 185APO 0.8x Reducer achieve a flat field?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe reducer uses a \u003cstrong\u003e4-element quadruplet optical design\u003c\/strong\u003e. This sophisticated lens arrangement is engineered not only to reduce the focal length but also to correct for off-axis aberrations like field curvature and coma, which are common in fast optical systems. This ensures that stars are sharp and round from the center of the image to the corners of a full-frame sensor.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs the 55mm back focus on the 185APO reducer compatible with my DSLR?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes. The standard 55mm back focus is the industry standard for DSLR and mirrorless cameras when using a typical T-ring adapter.

This wider field of view is much better suited for capturing the full extent of massive objects like the Andromeda Galaxy (M31) or the Veil Nebula complex on a full-frame sensor.

You'll need to account for the light path consumed by your equipment. If your camera sensor's back focus is 17.5mm and your filter wheel is 20mm thick, you have used 37.5mm of the available 55mm.
