This 8x50 finderscope uses fully coated optics to produce bright, wide-field images, making it easy to spot guide stars and frame targets using its built-in crosshairs.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eBright 8x50 Optics with Centering Crosshairs\u003c\/h3\u003e\n\u003cp\u003eWith a generous 50mm objective lens, this finder gathers significantly more light than standard 30mm or smaller finders, revealing fainter stars and subtle details in deep-sky objects. The 8x magnification provides a wide field of view to easily place objects in context, while the fully coated optics ensure maximum light transmission for a bright, clear image. Integrated crosshairs provide a precise reference point, allowing you to center your target with confidence before switching to high power in the main telescope.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eQuick-Release 50mm Mount with Sprung Alignment Screws\u003c\/h3\u003e\n\u003cp\u003eThe AG8 finder includes a robust mounting system designed for convenience and stability. The finder bracket attaches to a fixed dovetail shoe, allowing you to remove and reinstall the finder in seconds without losing alignment, which is ideal for transportation and storage. Alignment with the main telescope is achieved via sprung-loaded adjustment screws, which hold collimation securely while making fine-tuning simple and intuitive.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eStraight-Through vs. 90-Degree Finder: Which is Right for You?\u003c\/h3\u003e\n\u003cp\u003eOrion Optics UK offers both straight-through and 90-degree finders, each with distinct ergonomic advantages. The AG8's straight-through design is highly intuitive, as it allows you to aim by looking directly along the main telescope tube, making initial object acquisition fast and natural. While this can require an awkward viewing position for objects near the zenith, many observers prefer its direct line-of-sight approach. A 90-degree finder offers a more comfortable viewing angle for overhead targets but can feel less intuitive for initial pointing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhy choose the Orion Optics UK AG8 50mm finder?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eA 50mm finder like the AG8 is a significant upgrade over smaller, standard finderscopes. Its larger aperture gathers more light, allowing you to see fainter stars and locate deep-sky objects that would be invisible in a 30mm finder. This makes it an essential tool for astronomers who manually locate objects or need to identify faint guide stars.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the advantage of the AG8 Straight Finder's design?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe straight-through design allows for very intuitive aiming. You look along the same axis as the main telescope, making it easy to point the instrument to the correct patch of sky. This is often faster for coarse aiming than using a right-angle finder, which can present a corrected but less intuitive orientation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow do I align the AG8 Straight Finder with my main telescope?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eAlignment is straightforward using the sprung-loaded adjustment screws. First, aim your main telescope at a distant, stationary object during the day (like a telephone pole) or a bright star at night. Then, while looking through the finder, turn the adjustment screws until the crosshairs are centered on the exact same object. The springs provide tension to hold the alignment securely.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs the AG8 finder suitable for a computerized GoTo mount?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes. While GoTo mounts automate finding, a good finderscope is still invaluable for the initial alignment process. Using the bright, wide view of the AG8 to center your initial alignment stars ensures much greater GoTo accuracy for the rest of your session.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow would the AG8 8x50 finder help locate the Andromeda Galaxy (M31) with an 8\" Dobsonian?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eWith an 8\" Dobsonian, you would first point the telescope in the direction of the constellation Andromeda. The AG8's wide field of view and 8x magnification would then allow you to easily star-hop from the bright star Mirach (Beta Andromedae) to M31. The 50mm aperture is large enough to show the galaxy's faint core as a distinct smudge, confirming you have the correct object before viewing it in the main eyepiece.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs the AG8 bright enough to find objects like the Ring Nebula (M57) from a light-polluted suburb?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, the 50mm aperture is a major asset in light-polluted skies. While M57 itself will be too small to resolve in the finder, the AG8 will clearly show the stars of the constellation Lyra that you need to identify its location. The finder's light-gathering power helps faint stars stand out against the brightened sky background, making star-hopping possible even under suburban conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ctable class=\"DAV-specifications\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eAG8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eStraight-Through Finderscope\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAperture\u003c\/td\u003e\n\u003ctd\u003e50mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMagnification\u003c\/td\u003e\n\u003ctd\u003e8x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptics\u003c\/td\u003e\n\u003ctd\u003eFully Coated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReticle\u003c\/td\u003e\n\u003ctd\u003eCrosshairs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eQuick-release dovetail shoe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAlignment\u003c\/td\u003e\n\u003ctd\u003eSprung-loaded adjustment screws\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cul class=\"DAV-grid\"\u003e\n\u003cli class=\"DAV-grid-item\"\u003e\n\u003cdiv\u003e\n\u003cp class=\"DAV-item-title\"\u003e8x50 Straight-Through Finder Scope\u003c\/p\u003e\n\u003cp class=\"DAV-item-subtitle\"\u003e× 1\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli class=\"DAV-grid-item\"\u003e\n\u003cdiv\u003e\n\u003cp class=\"DAV-item-title\"\u003eFinder Bracket with Sprung Adjustment Screws\u003c\/p\u003e\n\u003cp class=\"DAV-item-subtitle\"\u003e× 1\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli class=\"DAV-grid-item\"\u003e\n\u003cdiv\u003e\n\u003cp class=\"DAV-item-title\"\u003eQuick-Release Dovetail Shoe (Base)\u003c\/p\u003e\n\u003cp class=\"DAV-item-subtitle\"\u003e× 1\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cul class=\"DAV-grid\"\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/davidastro.com\/pages\/orion-optics-uk-warranty-policy\" rel=\"noopener\" target=\"_blank\"\u003eOrion Optics UK 1-Year Warranty\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Orion Optics UK","offers":[{"title":"Default Title","offer_id":52942359494941,"sku":"OOUK-AG8-STRAIGHT-FINDER-50MM-WIDE","price":161.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/OrionOpticsUK-Straight-finder-50mm-wide-field-1_b9d4fa9a-ee18-4a73-acc9-27f8184cce10.jpg?v=1789606585","url":"https:\/\/davidastro.com\/fr-us\/products\/orion-optics-uk-ag8-straight-finder-50mm-wide-field","provider":"David Astro","version":"1.0","type":"link"}
