deep space imaging and viewing.\u003c\/p\u003e\n\u003cp\u003eThe exciting 7.5\" f\/5.3 Mak-Newt from Sky-Watcher is just what astrophotographers and serious deep space visual observers have been looking for. It uses a hybrid optical system that combines a Newtonian reflector's parabolic primary mirror with a Maksutov's spherical front corrector. The result is a system that corrects for both coma and spherical and chromatic aberrations.\u003c\/p\u003e\n\u003cp\u003eThe Maksutov-Newtonian design provides large aperture\/fast focal ratio apochromatic performance similar to that of a fine refractor with exceptional field correction in a compact and affordable package. The small secondary obstruction yields a sharper and higher contrast image than a Schmidt-Cassegrain - both visually and photographically. The fast f\/5.3 focal ratio makes the Sky-Watcher Mak-Newt an excellent wide field photographic instrument for deep sky imaging.\u003c\/p\u003e\n\u003cp\u003eThe optical tube is made of rolled steel, powder-coated gloss black, with gold fleck accents. The front and rear cells are painted die-cast aluminum. The front cell is perforated to allow faster cool down of the Maksutov corrector. A precision 2\" Crayford focuser is standard. The smooth backlash-free focuser has both coarse and ultra-fine (10:1 ratio) focusing knobs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures of this 180mm Sky-Watcher Maksutov-Cassegrain . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMaksutov-Newtonian optics:\u003c\/strong\u003e 7.5\" (190mm) aperture, 1000mm focal length, f\/5.3. The optical system uses Pyrex mirrors (a parabolic primary and a diagonal flat). The parabolic primary mirror helps correct for spherical aberration. The diagonal mirror is attached directly to the Maksutov corrector, instead of being supported by a traditional Newtonian reflector's spider vanes. This eliminates the diffraction spikes typical of spider vanes to improve contrast. The Maksutov spherical corrector lens is made of premium Schott crown optical glass and is fully multi-coated on both sides with multiple layers of anti-reflection materials for high light transmission and good contrast. Internal baffling reduces stray light to further improve the contrast.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFocuser:\u003c\/strong\u003e Dual-speed 2\" Crayford type with 10:1 ratio fine focusing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2\" eyepiece:\u003c\/strong\u003e The 36x eyepiece is a fully multi-coated three-element Sky-Watcher 28mm LET design with a long 20mm eye relief and a twist-up eyecup.

small and distant and needs a lot of power to resolve clearly. Its Maksutov-Cassegrain folded optical system provides sharp, high contrast images - mountains and craters on the Moon; major surface details on Mars; multiple storm bands on Jupiter; even Cassini's Division in the rings of Saturn occasionally pops into view in good seeing conditions.\u003c\/p\u003e\n\u003cp\u003eOutside the solar system, the high resolution 102mm Sky-Watcher splits close binary stars, resolves open star clusters, begins to reveal the brighter nebulas and galaxies, and more.

Built in clutch knobs on both axis allow for easy movement by hand. With certain mounts when you move the scope by hand you will lose your computer alignment.  Not with this one.  The dual encoders will keep exact axis aligment when you unlock the mount and move the scope manually.

One this it doesn't do is cost money.  It is free at the app store.  The app will control the mount wirelessly allowing you to align, move, control from your device.  The GPS unit will automatically update your location, day, date, time making it even easier to line up your mount.  Once you get it all aligned the SynScan has a fantastic tour abilty taking you around the night sky to the best objects that are available.  It has three tracking rates (solar, lunar, and sidereal) as well as 10 slewing speeds.\u003c\/p\u003e\n\u003cp\u003eAnd in closing, we can talk about the 5.3 pound tripod and pier extension.  The tripod is an adjustable height tripod with aluminum legs.  Its maximum height is 43.3\" and the extension pier will give you a few more inches making night time viewing a tad more comfortable while keeping vibration at a minimum.  The tripod legs will spread to 42.3 inches and are held in place with a spreader tray that is designed to hold personal effects or accessories while you are out observing.  The feet of the AZ-GTi are spiked to increase stability when you are on different types of terrain or soft ground.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable class=\"table\" id=\"product-attribute-specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eAperture\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e102mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e1300mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/12.7\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMotorized Controls\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eComputer GoTo Via Your Smart Device\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e13 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied Eyepiece\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e25mm and 10mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTelescope Type\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eMaksutov-Cassegrain\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eView Finder\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eRed Dot Non-Magnifying\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e2 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eSupplied Accessories: \u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eEyepieces: 1.25\" 25mm (52x) and 10mm (130x) 1.25\" Star Diagonal Red Dot Non-Magnified Finder AZ Mount Head Pier Extension Tripod Spreader Tray\u003c\/span\u003e\u003c\/p\u003e","brand":"Sky-Watcher","offers":[{"title":"Default Title","offer_id":40481985560649,"sku":"S21120","price":649.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/files\/AZ-GTi102_Main_1800x1800_317f9503-9917-4f52-a53d-4b02b5299558.webp?v=1723143714"},{"product_id":"sky-watcher-skymax-127-az-gti-127mm-f-12-goto-maksutov-cassegrain-telescope","title":"Sky-Watcher Skymax 127 AZ-Gti 127mm f\/12 Goto Maksutov-Cassegrain Telescope","description":"\u003cul class=\"top-section-list\" data-selenium=\"highlightList\"\u003e\n\u003cli class=\"top-section-list-item\"\u003e127mm Aperture Maksutov-Cassegrain OTA\u003c\/li\u003e\n\u003cli class=\"top-section-list-item\"\u003e1500mm Focal Length, f\/12 Focal Ratio\u003c\/li\u003e\n\u003cli class=\"top-section-list-item\"\u003eMotorized Computer-Controlled AZ Mount With Built In WiFi\u003c\/li\u003e\n\u003cli class=\"top-section-list-item\"\u003eTwo 1.25\" Eyepieces, 90° Diagonal\u003c\/li\u003e\n\u003cli class=\"top-section-list-item\"\u003eAluminum Tripod with Extension Pier\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis 127mm (5\") aperture Sky-Watcher Maksutov-Cassegrain provides exceptional high contrast\/high resolution solar system images at a very sensible price.
