Compared with its siblings, the 500mm-focal-length refractor has an aperture size of 90mm (f\/5.6), so Askar FRA500 can better fit into the scenarios of deep-sky imaging than Askar FRA400. Besides, its more lightweight and compact than Askar FRA600, which makes it a great choice for out-door observation or astrophotography.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"ie_line\"\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"reset_style\" id=\"ie_text-1669698397151\"\u003e\n\u003cdiv\u003e\n\u003cp\u003e\u003cspan\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0691\/1456\/0826\/files\/FRA500_features.png?v=1717209850\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eAskar FRA500 has inherited the legacies of superior FRA- series designing. 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\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\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. The 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. So the FRA500 can piggyback carry finders, guiders or other potential astronomy accessories. Askar FRA500 comes also with a pair of sought-after tube rings. On the top of the tube rings attached a handle and at the bottom, there is an Askar Losmandy-style dovetail plate. The combination of milk-white main tube and dew shield together with a high-gloss piano-black focuser makes the optical tube assembly calm and deep which is offset by the bright red decorative ring and tube rings.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe Askar FRA500 is 410mm long and weighs about 4kg , so it’s quite convenient for users to carry around or mount on an EQ mount. It’s particularly suitable for astronomy enthusiasts who frequently engage in long-distance trips or out-door astrophotography. Askar FRA500 together with the FRA- family is well received for large aperture, fast speed, delicate focusing system, unique optical design and the subsequently high-quality imaging results. Wish the Askar FRA500 be a loyal companion alongside your journey of astrophotography.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ie_fimg\" id=\"ie_fimg-1669698397156\"\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/omo-oss-image.thefastimg.com\/common\/design\/detail\/c8e2b9f1-0f48-47c5-8eac-571ac50b628e.jpg\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cbox-15 p_loopItem\" id=\"saf-detail-1\"\u003e\n\u003cdiv class=\"e_richText-17 s_title clearfix\"\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/omo-oss-image.thefastimg.com\/portal-saas\/new2022072923460240318\/cms\/image\/82e10c60-f5d6-481e-99e2-0bedf1094a0e.jpg\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cbox-15 p_loopItem\" id=\"saf-detail-2\"\u003e\n\u003ch3 class=\"e_h3-18 s_summary\"\u003eVideo\u003c\/h3\u003e\n\u003cdiv class=\"e_richText-17 s_title clearfix\"\u003e\n\u003cdiv class=\"video-box\" controlslist=\"nodownload\"\u003e\u003ciframe height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/YV7yslgJD1M?si=5MHQ6Ptf3vlXck6b\" title=\"YouTube video player\" width=\"560\" allow=\"accelerometer;

Chromatic aberration is a common optical aberration that causes colored edges or blurring around the edges of objects in an image.

Many users have some concerns about the limited space for installing additional astronomical accessories along the use. To address this, we have specially set finder bases on both sides of the focuser. This not only eliminates the need for disassembly when changing the position of the finder scope but also provides additional mounting positions for other astronomical accessories.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe handle of the Askar 120APO has a special slot design, making it also a base for installing a finder scope.

inherited the consistent quality, compactness and versatility, from the FMA family while possesses incomparable speciality. As its name indicates, FMA135 was born with a primary mirror plus a flattener. The primary mirror features an APO triplet structure with a diameter of 30mm and a focal length of 135mm, one of which is an ED glass.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan\u003eThe flattener contains three elements which is designed to support APS(advanced photo system) sky imaging and to control the performance at the edge of the photo. The exquisite optical design is the major contribution for its matchless ability in both visual observation and astrophotography as well as chromatic aberration control. Further, the FMA135 can also work as an excellent finder or guider. Its lightness and grace make it possible to attach the FMA135 to various cameras with corresponding adapters. Once attached, the FMA135 turns to be a 135mm manual lens, which will absolutely bring you an magnificent experience in ground object imaging.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan\u003eThere is 1.25\" female thread at the front of the astrograph suitable for all purchasable 1.25\" filters and standard M42×0.75 male thread at the back which accommodates most stock DSLR or astronomy cameras (an extra adapter is needed). Our standard configuration includes a tube ring for the installation of Vixen finder base, a 1.25\" visual back for the attachment of an eyepiece or a guiding camera as well as a high-quality focuser

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. One 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\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan\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\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan\u003eFMA230 is equipped with useful standard accessories.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan\u003eThe pair of tube rings are artistically pierced.

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\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan\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

Instead of buying extra flatteners, calculating the back focus of the flattener, or making a tedious connection to match the correct distance, astrophotographers can simply equip it with any possible imaging accessories, make the target stay at the focus, and then the whole optical system is perfect for imaging.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv class=\"cbox-15 p_loopItem\"

Instead of buying extra flatteners, calculating the back focus of the flattener, or making a tedious connection to match the correct distance, astrophotographers can simply equip it with any possible imaging accessories, make the target stay at the focus, and then the whole optical system is perfect for imaging.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan\u003e65PHQ has a smaller size than other PHQ astrographs. 65PHQ has a focal ratio of f\/6.4 and a focal length of 416mm. Instead of the quadruplet structure of other PHQs, the 65PHQ is a quintuplet with two ED glasses which offers excellent control of chromatic and other aberrations. With its self-flattening design, 65PHQ offers strong advantages in the astronomical shooting.

107PHQ","description":"\u003cp\u003e\u003cspan\u003eAs the first long-focal-ratio Flatfield astrograph from Askar, 107PHQ is born with a special mission: whether you are just getting started in astrophotography, or an enthusiast who has been quite familiar with all equipment and devices, you can always find Askar 107PHQ a useful astrograph which is functionally practical and physically attractive. It’s especially amateur or beginner friendly since you don’t need to attach an extra field flattener to get a satisfactory picture. And for the fact that you don’t need a flattener and you can easily get over back-focus calculation and confusing connection steps, all you need to do is to equip your 107PHQ with any possible imaging devices, make the target stay at the focus, and then the whole optical system is perfect for imaging.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv class=\"e_loop_sub-15 s_list\"\u003e\n\u003cdiv

getting started in astrophotography, or an enthusiast who has been quite familiar with all equipment and devices, you can always find Askar 107PHQ a useful astrograph which is functionally practical and physically attractive. It’s especially amateur or beginner friendly since you don’t need to attach an extra field flattener to get a satisfactory picture. And for the fact that you don’t need a flattener and you can easily get over back-focus calculation and confusing connection steps, all you need to do is to equip your 107PHQ with any possible imaging devices, make the target stay at the focus, and then the whole optical system is perfect for imaging.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"ie_text-1669638607974\" class=\"reset_style\"\u003e\n\u003cdiv\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eAskar 107PHQ, a versatile all-rounder\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"ie_text-1669639031615\" class=\"reset_style\"\u003e\n\u003cdiv\u003e\n\u003cp\u003e\u003cspan\u003eAskar 107PHQ can literally be applied in any conceivable situations, and that’s the top reason why 107PHQ is produced: to slash as much trouble for users as possible.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eAskar 107PHQ, an f\/7 astrograph, contains four pieces of lenses including two pieces of ED glass, which can better reduce chromatic aberration.

The aperture is 151mm, which is the largest of Askar refractors so far. The quadruplet lens with two ED glasses offers excellent control of chromatic and other aberrations. With its self-flattening design, 151PHQ offers strong advantages in the 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e151PHQ 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\/4.9 and a focal length of 740mm, effectively reducing exposure time. The multifunctional handle comes with a central slot for attaching an M6 screw with an M6 screw hole.

ratio of f\/2.8(15028HNT). It has garnered a quite large following since its advent. Not indulging in this great achievement, Sharpstar keeps the creativity and dynamism, introducing 13028HNT to our customers, which has a same focal ratio but a slightly smaller aperture size. 13028HNT, with a hyperbolic primary mirror, produces round and sharp stars within the full-frame and supports 44mm image circle. Compared with the focal ratio of f\/4, 13028HNT can attain the same image quality while save almost half of the exposure time.

The thermal expansion coefficient is smaller than ordinary glass. The dielectric multilayer coating makes the primary mirror obtain a highly reflective ability up to 97%. The minor axis of the secondary mirror is 65mm, enabling sufficient illumination for full-frame imaging. It’s worth mentioning that, the corrector is renovated to a two-refractive-lens set, one of which is an ED glass, aiming to simplify the optical system while enhancing the power in aberration correction.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe telescope tube is totally made of high-end carbon fiber material, so the weight of the telescope can greatly lessen and the overall appearance may artistically build up.

tubes—not too big, not too small. This rugged aluminum optical tube is only 22 inches long and weighs just 20 pounds, making it easy to transport and set up. But the views are much more impressive than what you’d expect from such a compact instrument. The tube offers a focal ratio of f\/10 with the added versatility of Fastar (see below).\u003c\/p\u003e\n\u003cp\u003eIt is equipped with Celestron’s patented StarBright® XLT optical coatings, which visibly increase contrast and light transmission for brighter deep space images and shorter exposure times.

This was the year that Celestron joined forces with the Santa Barbara Instruments Group (SBIG) to produce Fastar, a revolutionary add-on to Celestron’s hugely popular Schmidt-Cassegrain (SCT) optical system.\u003c\/p\u003e\n\u003cp\u003eWith Fastar, the SCT’s secondary mirror can be removed and replaced with a field-flattening lens assembly (sold separately by third party manufacturers) so that a CCD camera can be used in the front of the telescope at the f\/2 focus of the instrument’s primary mirror. The potential of the Fastar system is staggering: exposures are 25 times shorter than if the camera was placed at the instrument’s native f\/10 focus. Imagers can capture galaxies and nebulae with exposures of just 30 seconds.\u003c\/p\u003e\n\u003cp\u003eFor more information about our Fastar technology,\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/www.celestron.com\/pages\/fastar-technology\"\u003evisit here\u003c\/a\u003e. \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"http:\/\/www.celestron.com\/university\/astronomy\/starbright-xlt-optical-coating-system\"\u003e\u003cstrong\u003eStarBright XLT coatings\u003c\/strong\u003e\u003c\/a\u003e\u003cspan\u003e\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eStarBright XLT is Celestron’s revolutionary optical coating system.

The APS-C sized sensors used in many mirrorless cameras are a good choice. 42mm full frame sensors will also work, but performance will be poor at the edges of the sensor and field illumination will be reduced.

The design consists of a Schmidt corrector, primary mirror, lens group, and optical window. The lens group contains 4 elements and utilizes rare-earth elements. Unlike many telescopes that only perform well over the visible spectrum (400-700nm), the 8” RASA’s optics are designed to perform over a wider spectral range, from 400nm – 800nm. This allows more of the light emitted from the astronomical object to be sharply focused in the image.\u003c\/p\u003e\n\u003cp\u003eWith many imaging systems, adding an extra piece of flat glass such as a filter does not change optical performance. However, that is not the case with super-fast optical systems like the RASA. Our engineers addressed this by designing the RASA with a removeable optical window, so you can maintain peak optical performance if a filter is added or if a camera has its own optical window. Celestron offers a Light Pollution Imaging Filter designed specifically for the 8” RASA, which mounts in place of the optical window.\u003c\/p\u003e\n\u003cp\u003eAll refractive optical surfaces are coated with StarBright XLT coatings, while the primary mirror uses enhanced aluminum coatings.

This wavelength is critical for studying solar phenomena like spicules, prominences, filaments, sunspots, and solar flares in great detail. Unlike standard white-light telescopes, which capture the Sun's broad spectrum, Hα solar telescopes offer a window into specific solar activity in the chromosphere, a layer of the Sun's atmosphere located just above the photosphere.\u003c\/p\u003e\n\u003ch1 class=\"MsoNormal\"\u003eEtalon Filter Technology\u003c\/h1\u003e\n\u003cp\u003eAt the heart of most Hydrogen Alpha solar telescopes lies the etalon filter, a highly precise optical device that isolates the Hα wavelength from the rest of the Sun’s emitted light. An etalon is a type of interferometer, consisting of two parallel mirrors separated by a precise distance. The etalon works by reflecting light multiple times between the mirrors, selectively allowing only wavelengths that satisfy specific resonance conditions to pass through.\u003c\/p\u003e\n\u003cp\u003eIn the case of Hα solar telescopes, the etalon is designed to transmit light at the Hα wavelength while rejecting all other wavelengths. The key to the etalon’s performance lies in its ability to tune the wavelength allowed through the filter. This is achieved by adjusting the distance between the mirrors or by slightly tilting the etalon, which changes the angle of incidence. Tuning the etalon to each side of the central wavelength is needed because local changes in atmospheric pressure change the refractive index of your local air mass.   The Sun's emission at Hα can also shift slightly due to Doppler effects as violent explosions in the Sun's chromosphere can cause solar plasma to move at enormous speeds. \u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThere are two primary types of etalon filters used in solar telescopes: single etalon and double etalon systems.\u003c\/p\u003e\n\u003cp\u003eTraditional H alpha solar telescopes have been sold in two basic configurations; single etalon and the very costly double etalon systems.  It has always been a choice of the single etalon's brighter prominences or more contrast of surface features from an additional etalon.  The second etalon has the unfortunate consequence of reducing the brightness of the system by a whopping 40%.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSolis Etalon Technology:\u003c\/strong\u003e Sky-Watcher's all new Solis technology allows the Heliostar to achieve a 0.55A bandpass without the costly expense and complexity of a second etalon to achieve the same or better performance without reducing the brightness significantly.
