FMA180 pro is similar to the FMA180 in optical design. The objective lens features a sextuplet air-spaced APO design and includes two pieces of ED (extra-low dispersion) glass, providing excellent correction of chromatic aberration. In addition to visual observations, the FMA180 pro is specially optimized for strophotography. Compared to FMA180, FMA180 pro adds a finder base and a 360° rotator. What' s more, the focuser is designed as internal focusing which promotes its stability and ensures its performance in use as a delicate, high-quality, and compact

The front objective lens comprises three lenses and the posterior reducer is composed of four lenses and thus it’s sometimes dubbed as a “three at the front and four at the rear” system. The aperture size of the objective lens is 50mm and the original focal length is 275mm thus we’ve got a relatively fast focal ratio of f\/5.5. The objective lens contains two ED glasses which are adapted to cure chromatic aberrations.\u003c\/p\u003e\n\u003cp\u003eOne can barely find an equal counterpart in the market as designing a three-element apochromatic objective lens in astrograph with such size demands more on craftsmanship and processing technique. We made it because we consistently cling to the belief that we have to deliver a better imaging result to our customers. The FMA230 can solely function as a lens to observe the ground scenery or stars in the sky, or as a telescope for direct-focus photography. You should just fine-tune the helical focuser to perfectly focus without adding extra optical devices.\u003c\/p\u003e\n\u003cp\u003eThe four-element reducer is a 0.84×optical device which can change the the FMA230 into a 50mm-aperture astrograph with a focal length of 230mm and a focal ratio of f\/4.6. The reducer is designed specially for sophisticated astrophotography, which plays an essential role in improving the image quality generally across the whole field of view. And it pays special attention to the stars at the edge of the image. The pictures will be greatly enhanced and detailed under the help of this dedicated reducer even the imaging equipment you use is a rather professional full-frame ordinary or astronomy camera.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/www.askarlens.com\/Upload\/162521543574.jpg\" width=\"531\" height=\"375\"\u003e\u003c\/p\u003e\n\u003cp\u003eFMA230 is equipped with useful standard accessories.\u003c\/p\u003e\n\u003cp\u003eThe pair of tube rings are artistically pierced. Its stalks are lengthened which means that the tube rings provide more room for the devices, like a camera, that are attached to the FMA230, so they won’t collide with the dovetail plate under the astrograph.\u003c\/p\u003e\n\u003cp\u003eThe FMA230 comes with a Vixen-style dovetail plate. Screw the tube-ring-wrapped astrograph onto the dovetail plate and then directly slide the assembly into the slot on top of an equatorial mount. The slot at the center of the dovetail plate is carved for the attachment to a tripod. It’s quite convenient and helpful especially when you carry out some ground imaging or observation.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/www.askarlens.com\/Upload\/4(4).jpg\" width=\"520\" height=\"368\"\u003e\u003c\/p\u003e\n\u003cp\u003eIn order to solve the awkwardness of carrying around your astrograph when you engage in field astrophotography, the FMA230 is designed with a pretty-looking and utility handle. The detachable handle is installed on the top side of the tube ring. The handle is not just literally a handle, the dovetail slot carved out of the handle can also be a base for the attachment of finders, guiders or ASIAIRs that have a corresponding dovetail foot. So you have more room to integrate as many accessories as possible. Besides, the handle is carved with 45°Arca-swiss style slots at the sides, so an upside-down handle can be directly slid into a corresponding Arca-swiss clamp on a camera tripod.\u003c\/p\u003e\n\u003cp\u003eThe lightweight and compact FMA230 is a new sibling from the Askar FMA- family, it will definitely bring your observing and imaging experience to a whole new level!\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong\u003eAperture:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e50mm\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eFocal length:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e275mm, 230mm（with the reducer）\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eFocal ratio:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003ef\/5.5, f\/4.6 (with the reducer）\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eObjective lens:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003eTriplet air-spaced APO with two ED glasses, Septuplet full-frame astrograp (including the reducer)\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eLength\u003c\/strong\u003e\u003cspan\u003e：248mm (imaging with the reducer), 221mm (observing without a diagonal)\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003cspan\u003e：1045g\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eRear-end adapter type:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003eM48×0.75（for imaging), 2″ socket（for observation）\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003ePackage items:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003ean FMA230 astrograph, a pair of tube rings, a Vixen-style dovetail plate, a manual, 2″ adapter\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cspan\u003e\u003cimg src=\"https:\/\/www.askarlens.com\/Upload\/162521550850.jpg\" width=\"613\" height=\"461\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003e\u003cimg src=\"https:\/\/www.askarlens.com\/Upload\/162521552539.jpg\" width=\"608\" height=\"457\"\u003e\u003c\/h3\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eFMA230 astrograph\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003ePair of tube rings\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eVixen-style dovetail plate\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eManual\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e2″ adapter\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/www.askarlens.com\/Upload\/4(4).jpg\" width=\"504\" height=\"356\"\u003e\u003c\/p\u003e\n\u003cdiv class=\"value\" data-mce-fragment=\"1\"\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eWarranty \u0026amp; Manuals\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003eAskar Warranty\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cimg src=\"https:\/\/www.askarlens.com\/Upload\/162521548120.jpg\" width=\"684\" height=\"484\"\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cimg src=\"https:\/\/www.askarlens.com\/Upload\/162582116249.png\" width=\"681\" height=\"345\"\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e \u003c\/p\u003e\n\u003c\/div\u003e","brand":"Askar","offers":[{"title":"Default Title","offer_id":43628298141925,"sku":"ASK-FMA230","price":973.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/askar-fma230-f4-6-astrograph-lens-fma230-astronomy-plus.webp?v=1690488387"},{"product_id":"askar-fma180-pro-af-kit-fma180pro-af-kit","title":"Askar PRO AF Kit for FMA180 (FMA180PRO-AF-KIT)","description":"\u003ch2\u003eAskar PRO AF Kit for FMA180\u003cspan style=\"font-size: 0.875rem;\"\u003e \u003c\/span\u003e\n\u003c\/h2\u003e\n\u003cdiv class=\"e_container-3 s_layout response-transition\"\u003e\n\u003cdiv class=\"cbox-3-1 p_item\"\u003e\n\u003cp class=\"e_text-8 s_title response-transition\"\u003eWith the upgrading of electronic astronomical accessories, electronic devices are more and more widely used in astronomical observation and astrophotography.
