Its air-spaced Triplet objective, made with Japanese OHARA glass, provides clear images with sharp stars right to the edges. Even when enlarging the image, you can enjoy great contrast. Add this expert in all areas of astrophotography to your equipment.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHighlights:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTriplet objective with FPL-53 and FPL-51 optical elements,\u003c\/li\u003e\n\u003cli\u003eimages with pure colors and exceptional contrast,\u003c\/li\u003e\n\u003cli\u003e2.9\" focuser with diagonal rack-and-pinion and 1:10 micro-focusing for better illumination,\u003c\/li\u003e\n\u003cli\u003egreat compatibility thanks to a 2\"\/1.25\" reducer and M74 thread,\u003c\/li\u003e\n\u003cli\u003eincludes an aluminum case for transport.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eTop-level optical system\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eObserving a planet with this apochromat is an amazing experience. Unlike most refractor telescopes on the market, with this one you enjoy greater contrast and much more detail. Planets appear sharper, as do star clusters and other Deep-Sky objects.\u003c\/p\u003e\n\u003cp\u003eThis is possible because it features one of the best optical systems we've ever seen at Astroshop. A Triplet objective with two OHARA elements, one FPL 53 and one FPL 51, which completely eliminate chromatic aberration. To capture incredibly beautiful and completely unique astrophotos, this is a must-have.\u003c\/p\u003e\n\u003cp\u003eUnlike mirror-based systems, image definition is far superior in apochromats, as there is no obstruction in the light path. Furthermore, when it comes to the subtle nuances that make up image contrast, refractors are unbeatable.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHybrid 2.9\" focuser for full illumination\u003c\/b\u003e\u003cbr\u003eThis apochromat features a 2.9\" focuser to allow connection of any camera. Whether you have an APS-C chip or a full-frame one, the optical system of this instrument always ensures maximum illumination. The focuser is focused with a diagonal rack-and-pinion and moves on a bearing system. Achieving perfect focus is no challenge with this telescope, no matter how heavy your camera is.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e360º Rotation\u003c\/b\u003e\u003cbr\u003eSince the focuser can be rotated 360º, you no longer have to worry about not being able to photograph a particular object because the camera is improperly installed or a long object won't fit on the chip.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e1:10 Dual-speed micrometric reduction\u003c\/b\u003e\u003cbr\u003eTo focus on an object, you need to follow these two steps: locate the object with the coarse focus and refine with the 1:10 precision wheel. This wheel achieves the exact point of focus. However, as any astrophotographer knows, hitting the exact point without overshooting is not easy. The focusing wheel is so precise that it reacts to any small change, so you always find the perfect focus.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e1.25\", 2\", and M74 type connection\u003c\/b\u003e\u003cbr\u003eThe 2.9\" focuser has a standard 2\" connection point and a 1.25\" reducer. Thanks to this, your equipment is compatible with accessories from our store, such as eyepieces and adapters. Additionally, an extra M74 thread allows you to use a full-frame camera if desired. The result is a fully illuminated image with a flat field of view.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCNC machined tube\u003c\/b\u003e\u003cbr\u003eThe tube of this Omegon apo has been manufactured from metal using computerized numerical control machines and features a system that prevents light reflections.

This type of aberration manifests as a loss of sharpness at the edges of images. Outside the center of the field of view, stars do not appear as bright points and unfocused rings also appear. But the Omegon Field Flattener lens pulls out distortion-free photos with no tricks... Say the magic words and marvel at photos with bright and completely sharp stars across the entire field of view.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eMake the problem disappear\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eAlthough very common, this type of aberration goes unnoticed during observation or photography with small chips. But when using cameras with larger or full-frame chips to capture the sky, this distortion comes into play. You can always crop the edge of an image afterwards, but did you invest so much in a large chip camera just for that? The most elegant solution to this problem is this Omegon lens.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCompletely flat field\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe photographic field becomes completely flat when using the Field Flattener lens, and the focal length is not altered.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCompatible with 126mm and 150mm Triplet APOs\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eIt can be used with Omegon Pro Carbon Triplet models with 126mm and 150mm apertures.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eM48 type thread for better illumination\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe lens features an M48 type thread on each side. The great advantage of this design is that it allows for full illumination, unlike T2 or M42 threads, which would limit the light rays. This is why telescopes with 2\" focusers have poorer illumination.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eIn short:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003efield flattening for refractors,\u003c\/li\u003e\n\u003cli\u003efor 126mm and 150mm Triplet telescopes,\u003c\/li\u003e\n\u003cli\u003eM48 type thread for full illumination with a 2\" diameter,\u003c\/li\u003e\n\u003cli\u003emulti-coating on all optical surfaces.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Omegon","offers":[{"title":"Default Title","offer_id":53581584597335,"sku":"47785","price":1752.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/45634_1.jpg?v=1779016005","url":"https:\/\/astrotelescopios.com\/en-uk\/products\/refractor-apocromatico-pro-apo-ap-104-650-ed-ota-2-field-flattener","provider":"Astro Telescopios","version":"1.0","type":"link"}
