The guiding telescope is absolutely solid, non-slip and will not be scratched! A further four milled planar surfaces with a photo-threaded hole are installed on the outer diameter in order to be able to attach additional accessories to the rings on the outside or to connect several rings together!\u003c\/p\u003e\n\u003ch2\u003eTrue No-Marr Clamp Screws\u003c\/h2\u003e\n\u003cp\u003eThe basic concept of guidescope rings remains unchanged since the dawn of the telescope. They consist of a simple ring with three radial machine screws arranged at 120 degrees, used to shift an auxiliary telescope to be aligned co-axially with the main instrument (or intentionally off axis for guidescope use). In this simplest configuration the three hard-pointed alignment screws bear directly against the tube of the auxiliary telescope, causing inevitable damage to the telescope's finished (painted) surface.\u003c\/p\u003e\n\u003cp\u003eSurprisingly, most currently available rings have evolved little from this basic design, and subject your valuable equipment to repeated damage. The simplest and most inexpensive solution, taken by some manufacturers, is to add a small plastic cap or pellet inserted into the tips of the adjusting screws. While this significantly reduces the damage, the rotation of the plastic screw tip against the telescope can still noticeably abrade a painted finish (particularly if there is any grit embedded in the plastic tip). Also, often these plastic tips are made of too small a diameter, which result in high clamp loads that can permanently dent a guidescope tube.\u003c\/p\u003e\n\u003cp\u003eThe solution for this problem lies in enabling the plastic tip to freely rotate, so that as the clamp screw is tightened, the tip remains stationary relative to the telescope tube surface. The clamp screws on our guidescope rings are designed in just this way. Each clamp screw incorporates a large 12mm diameter nylon tip, in order to spread the clamp force and prevent permanent denting of a telescope's thin wall tube. The nylon tip is mounted onto the flanged head of a machined brass spindle, which inserts into a lubricated bore in the tip of the large diameter stainless steel clamp screw. The net result is a rigid, truly no-marr adjustable guidescope ring.\u003c\/p\u003e\n\u003cdiv\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/5_955f37c7-152a-42db-a187-84df8e1ec8da.webp?v=1732380167\u0026amp;width=700\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003ch2\u003eModularity\u003c\/h2\u003e\n\u003cp\u003eOne of the distinguishing features of our guidescope rings is their ability to be interconnected with each other, or to easily attach other auxiliary equipment (finders, pointers, etc). Machined flats and mounting holes permit the rings to be assembled in a number of configurations, enabling you to mount and adjust multiple guidescopes, finder scopes, or other auxiliary instruments. These As shown in the image below, there are 5 locations around the periphery of each ring that have been machined as attachment points. Each location has a machined flat, and a central 1\/-4-20 threaded hole. Note: In order to couple multiple rings, you will need to drill out one of the 1\/4-20 holes with a 1\/4\" drill, in order to bolt to the adjacent ring.\u003c\/p\u003e\n\u003cdiv\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/4_3f216b94-ec4f-4927-8449-225de0009b03.webp?v=1732380181\u0026amp;width=700\"\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cspan\u003eShown below are some of the possible orientations that work for mounting 2 or more instruments:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/7_a47fdad3-9eeb-4a3d-a74c-5ee5d8f3cd3a.webp?v=1732380209\u0026amp;width=700\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/3_9e41d46d-11f1-411e-8a53-ce88c734c7e9.webp?v=1732380209\u0026amp;width=700\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/2_01620a87-0d45-4035-85f1-1ddf086cf7c1.webp?v=1732380210\u0026amp;width=700\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/1_fc043d78-9630-4e80-b0cd-592fce3ba60d.webp?v=1732380209\u0026amp;width=700\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eMounting\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eThe standard method for attaching these guidescope rings is to utilize the primary base 1\/4-20 mounting hole. Adjacent to this threaded hole are two unthreaded 5mm holes (28mm apart) that can also be used for additional mounting screws, or if your scheme requires screwing down through the ring into a base plate or telescope. Of course, you can easily enlarge or modify any of the mounting features to suit your needs. The extra heavy wall thickness and width of the rings makes them easy to rigidly attach to practically anything.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/6_6b305aa5-9196-4c7c-86da-71c42ca64310.webp?v=1732380246\u0026amp;width=700\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable id=\"product-attribute-specs-table\" class=\"data-table\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"first odd\"\u003e\n\u003cth class=\"label\"\u003eMANUFACTURER\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003eBaader Planetarium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth class=\"label\"\u003eEAN CODE\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003e4047825016461\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth class=\"label\"\u003eSKU (#)\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003e1500203\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth class=\"label\"\u003eWEIGHT (KG)\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003e1.746\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth class=\"label\"\u003eCOMPATIBLE BRANDS\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003eAll Telescopes in given Tube sizes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth class=\"label\"\u003eTUBE DIAMETERS\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003e140 – 185 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth class=\"label\"\u003eTUBE DIAMETER (MIN)\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003e140 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth class=\"label\"\u003eTUBE DIAMETER (MAX)\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003e185 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth class=\"label\"\u003eSCREW TYPE\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003e6x large handknobs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"last even\"\u003e\n\u003cth class=\"label\"\u003eSPECIAL FEATURES\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003eball bearing tips\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eWarranty\u003c\/h3\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eBaader 2 year warranty : Returns and Warranty Policies — Alpine Astronomical LLC\u003c\/p\u003e","brand":"Baader Planetarium","offers":[{"title":"Default Title","offer_id":52326109970733,"sku":"uex1787937847841","price":206.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0924\/0749\/7005\/files\/baader-guidescope-rings-bp-iii---140-185mm-gr7_1.webp?v=1787937854","url":"https:\/\/www.camomileridge.shop\/products\/baader-guidescope-rings-bp-iii-140-185mm-gr7","provider":"My Store","version":"1.0","type":"link"}
