We build and test the rack and pinion focuser to hold 12 lbs. of weight, yet still permit extremely fine focusing control via a 10:1 dual speed pinion assembly. This new draw tube also permits quick change from visual to imaging operation and allows full camera rotation without focus change.

makes it possible to combine sharpness and extraordinary contrast. This unique optical formula, based on a highly air-spaced ED triplet, has the advantage of completely eliminating spherical aberration while having the best chromatic correction in the Takahashi telescopes range. TOA excels in both high planetary resolution and deep sky imaging, fully exploiting the capabilities of cameras with the largest sensors.\u003c\/p\u003e\n\u003cp\u003eThe TOA-150B is equipped with an oversized 102 mm (4\") rack-and-pinion focuser (with 1\/7 microfocuser), a CAA (Camera Angle Adjuster) ring for photographic framing, an FQR-1 base for 7x50 finder scope and a retractable dew shield.

The Strehl ratio at optimal wavelengths of human vision is almost perfect, at 99.2%, equivalent to that of the TOA series.\u003c\/p\u003e\n\u003cp\u003eThe TSA-120 is therefore a lightweight, compact and economical refractor, whose performance is similar to that of the TOA, Takahashi's flagship models and recognized as among the best in the world.\u003c\/p\u003e\n\u003cp\u003eThe addition of the optional field corrector allows native focus imaging. The TOA-35 reducer (F\/5.25) makes it more comfortable in deep sky photography. All assemblies meet the rigidity and flexibility requirements of new imaging devices, such as digital cameras and the latest generation of CCD cameras.\u003c\/p\u003e\n\u003ch3\u003eTechnical

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

It boasts a quintuplet air-spaced APO optical structure, a “three plus two” Petzval lens combination. The front lens group consists of three lenses (including two pieces of ED glass) for excellent correction of aberrations. The posterior group is composed of two lenses separated by small space which is able to provide fine sharpness across the whole image. You may barely detect any blurry star at the edge of the image. FRA500 supports an image circle of amazing 55mm, much larger than the standard 44mm full-frame image circle. Its special back-focus design frees users from calculating confusing back-focus distance or rummaging around for a proper spacer. What you need to focus on is just to make your target stay in focus.\u003c\/p\u003e\n\u003cp\u003eAskar FRA500 is typically a wonderful mix of pragmatism and aesthetics. The astrograph shows smooth lines and a sound layout of components. From the front, the Askar FRA500 has an impressive dew shield decorated with a classic bright-red bezel ring. The total length of FRA500 is 452mm when the dew shield is stretched out and 410mm when contracted back. At the tail end of the astrograph locates a 3.5\" massively-built focuser with dual-speed hand knobs (twin knobs for coarse adjustment and one 1:10 fine adjustment knob), which is of great use in real observation or astrophotography.\u003cbr\u003e\u003cbr\u003eThe astrograph wears smooth coating and is evenly finished. The graduation inside of the focuser is quite clear and easily readable. The focuser is tough and solid, and on the left side of it, there is a standard finder base with a silver thumb screw.

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 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-130phq-astrograph-130phq","title":"Askar 130PHQ F\/7.7 Quadruplet Astrograph (130PHQ)","description":"\u003ch2\u003eAskar 130PHQ Astrograph\u003c\/h2\u003e\n\u003cp\u003e130PHQ is a long-focal-ratio, flatfield astrograph newly launched after 107PHQ. Instead of buying extra flatteners, calculating the backfocus of flattener or making tedious connection to match the distance, astrophotographers can simply equip it with any possible imaging devices, make the target stay at the focus, and then the whole optical system is perfect for imaging.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e130PHQ has a larger size than 107PHQ, with an aperture 23mm larger than 107PHQ. 130PHQ has a focal ratio of f\/7.7 which is longer than 107PHQ’ s f\/7, and a focal length of 1000mm. The quadruplet lens with two ED glasses offers excellent control of chromatic and other aberrations. With its self-flattening design, 130PHQ offers strong advantages in astronomical shooting. It supports a medium frame 60mm image circle, has a fine spot diagram with tiny distortion of the peripheral stars, and its central RMS radius is less than 2 microns.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e130PHQ comes with a telescopic lens hood, a high quality CNC machined and painted tube and attractive decorative parts.

When used with the 3\" 0.7 x flat field reducer, the telescope can reach a focal ratio of f\/5.4 and a focal length of 700mm, effectively reducing exposure time. The multifunctional handle comes with a central slot for attaching an M6 screw with an M6 screw hole.

It’s worth mentioning that all astrographs from PHQ- family come with an integrated lens combination rather than simply placing three major lenses and a corrector together in a line. In another word, the whole optical system cannot solely perform without any piece of these lenses. This structure design leads to a more rational lens arrangement, better vignette control and superior image quality. The focal ratio of 80PHQ is f\/7.5. It’s a “long” focal-ratio astrograph compared with other counterparts from Askar. It’s a little bit longer even compared with 107PHQ which is f\/7 in focal ratio.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cdiv\u003eSome users may be frustrated that it’s hard to make a trade-off between 107PHQ and 80PHQ, since there seems to be so much in common.

This innovative and revolutionary design combines a precision (Patented) internal focusing mechanism with the highest quality optics available, providing the ultimate Apochromatic refractor for astrophotography. Designed from the ground up with the ability to handle the newest generation of large, heavy, high-resolution cooled cameras, the rock-solid optical tube assembly is uncompromised in quality. The movement of the focuser is integrated inside the main tube assembly, so there are no movements of a focuser drawtube visible from the outside.  The user can enjoy the benefits of a traditional two speed fine focuser, while not worrying about limitations typically found in traditional rear mounted focusers. \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/thenewwifd_480x480.png?v=1675873568\" alt=\"\" width=\"615\" height=\"260\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/WIFDfocuserdesign_480x480.png?v=1675873667\" alt=\"\" width=\"549\" height=\"263\"\u003e\u003c\/p\u003e\n\u003ch2\u003eINTERNAL FOCUSER DESIGN\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eNEW internal focuser.  Our new design includes the Patented WO center focuser with precise internal sliding of fixed optics to prevent image shift.  The integrated position viewing window on the focuser provides instant verification of the graduated numerical display.  The smooth rack and pinion design is incorporated into the focuser to provide super fine adjustability for critical focus.  The internal movement of the optical elements is protected from the elements and can’t come out of alignment.  The redistribution of weight allows for better balance during imaging sessions.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp style=\"margin: 0px 0px 1rem; padding: 0px; color: #333333; font-family: 'Open Sans', Arial, 'Helvetica Neue', Helvetica, sans-serif; font-size: 17px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/WIFDFOCUSER_480x480.gif?v=1675873830\" alt=\"\" width=\"627\" height=\"419\"\u003e\u003c\/p\u003e\n\u003ch2\u003eDESIGN PRINCIPLE\u003c\/h2\u003e\n\u003cp\u003eScalable Design.  The WIFD series will allow for many sizes and is not limited to smaller refractors.   Additional optical designs are possible to meet various photographic requirements enhancing the line to include a number of apertures and fast focal ratios.\u003cbr\u003e\u003cbr\u003eInspired by the tremendous success of the WO CAT series of astrographs, William Optics has advanced the capabilities of astrophotography to the next level with this “no weight limit on photo accessories” design.  The solid tube where accessories are attached, has a rigid design, and will not flex or exhibit any change in the optical path regardless of the weight of the camera and filter wheel attached to it.\u003c\/p\u003e\n\u003cp style=\"margin: 0px 0px 1rem; padding: 0px; color: #333333; font-family: 'Open Sans', Arial, 'Helvetica Neue', Helvetica, sans-serif; font-size: 17px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/WIFDdesign_480x480.png?v=1675873934\" alt=\"\" width=\"640\" height=\"304\"\u003e\u003c\/p\u003e\n\u003ch2\u003eCAT DESIGN\u003c\/h2\u003e\n\u003cp\u003eImproved “CAT” design ring tubes and dovetail base are lighter while remaining equally rigid.
