A Barlow lens is integrated inside the \"Blug\" and features a multi-layer anti-reflective coating. The \"Blug\" is available in two sizes: 1.25\" and 2\". \u003cbr\u003e\u003cbr\u003e\u003cb\u003eWhat the \"Blug\" does\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003eWith truss-tube Dobsonians, the image of the Blug’s 45° wedge is clearly visible on the primary mirror during collimation. By observing the shadow of the concentric circles and the center mark, the mirrors can be adjusted along the optical axis. For solid-tube telescopes, the \"Blug\" must be rotated 180° outward to view the images, and you will need to observe the image from slightly further away during collimation. In those cases, we recommend the \"tuBlug\".\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:20px;margin-top:30px;\"\u003eMain features\u003c\/h2\u003e\n\n\u003cp\u003eHowie Glatter quality for a reliable and rewarding observing experience.\u003c\/p\u003e\n\n\u003cul style=\"padding-left:20px;\"\u003e\u003cli\u003eConnection (telescope side): 2\"\u003c\/li\u003e\u003c\/ul\u003e\n\n\u003ch2 style=\"font-size:20px;margin-top:30px;\"\u003eMain technical specifications\u003c\/h2\u003e\n\n\u003ctable style=\"width:100%;border-collapse:collapse;margin-top:10px;\"\u003e\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eBrand\u003c\/td\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eHowie Glatter\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eModel\u003c\/td\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eHowie Glatter Barlowed Collimation Plug\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eType\u003c\/td\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eMiscellaneous\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eConnection (telescope side)\u003c\/td\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003e2\"\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\u003cdiv style=\"background-color:#f0f8ff;padding:15px;margin-top:30px;border-left:4px solid #007acc;\"\u003e\n\n\u003cstrong\u003eFree shipping\u003c\/strong\u003e\u003cbr\u003eTake advantage of free shipping throughout Italy on orders over €199.99!\u003c\/div\u003e\n\n\n\u003c\/div\u003e","brand":"Howie Glatter","offers":[{"title":"Default Title","offer_id":51120674603224,"sku":"21635","price":125.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/0722\/6072\/files\/187e6a72f5bf455fa9e5c1dae9311246.jpg?v=1764069390","url":"https:\/\/www.giordanoastronomia.it\/en\/products\/howie-glatter-barlowed-collimation-plug","provider":"Giordano Astronomia","version":"1.0","type":"link"}
