With an extremely curvy design we can offer an excellent instrument produced in Italy with the best Italian style. The quality of materials is the best available on the market and technical solutions makes it absolutely unique.<\/p>\n<p>The graphic motif that characterizes the NADIRUS Dobson is the design of the wheel that identifies in the intersection of 6 circles of different diameters, and some suitably radiused corners, that will surround the profile. These curves are repeated on the body of the base with the aim of lightening.<\/p>\n<p>Even the base of the rotating system has been lightened with a pattern, unique, reminiscent of the blades of a fan.\u00a0\u00a0 Attention to the design, technique and mechanics, in the name of practicality which has been the dominant theme of this project.<\/p>\n<p>We privileged a structure in lamellar beech wood which makes it stable and lightweight. In particular, it has been taken care of the upper cylinder housing is where the spider secondary mirror holder which was made \u200b\u200bof birch plywood crossed beams that give the piece a unique strength and stability. Although the primary mirror cell is made of birch plywood with a support system where the 9-point floating mirror rests on discs of natural cork foam.<\/p>\n<p>Many mechanical and other technical details has been studied that confirming the right choice with your purchase and will give you the evidence of the high quality, taking you in the best condiction for your astronomical observations.<\/p>\n<p><span style=\"color: #0000cd;\"><span style=\"font-size: 14px;\"><strong>TECNICAL SPECIFICATION<\/strong><\/span><\/span><\/p>\n<p>Type\u00a0\u00a0\u00a0\u00a0 \u00a0\u00a0\u00a0\u00a0\u00a0 \u00a0 \u00a0 \u00a0 &#8211;\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 DOBSON TRUSS<br \/>\nCode\u00a0\u00a0\u00a0 \u00a0\u00a0\u00a0\u00a0\u00a0 \u00a0\u00a0 \u00a0\u00a0 &#8211;\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 10A003<br \/>\nEAN13-GS1 \u00a0 \u00a0\u00a0 &#8211;\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \u00a0\u00a0\u00a0 8058450361822<br \/>\nOptical design\u00a0 &#8211;\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \u00a0\u00a0 Newtonian<br \/>\nClear aperture\u00a0 &#8211;\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \u00a0 \u00a0 304 mm (12\u201d)<br \/>\nFocal length\u00a0\u00a0 \u00a0\u00a0 &#8211;\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 1500 mm<br \/>\nFopcal ratio\u00a0\u00a0\u00a0 \u00a0\u00a0 &#8211;\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \u00a0 \u00a0 f\/5<br \/>\nMount type &#8211; Wood Dobsonian<br \/>\nPrimary cell &#8211; 9 point aluminium maschined<br \/>\nSecondary holder &#8211;\u00a0\u00a0\u00a0 Hight precision aluminium assembly<br \/>\nFocuser \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 &#8211;\u00a0 Not included<br \/>\nAlignment \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\u00a0 &#8211; Manual<br \/>\nFinder \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 &#8211; Not included<br \/>\nRadius altitude bearings diam. &#8211;\u00a0 480 mm<br \/>\nTruss tubes\u00a0 &#8211; Powder painted alu.tubes with plastic balls diam.20<br \/>\nAlt movement \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 &#8211; By teflon<br \/>\nAzimuth movement &#8211; By teflon<br \/>\nTotal assemble telescope weight &#8211;\u00a0 16 Kg.<br \/>\nHeaviest part &#8211;\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 7,13 Kg.<br \/>\nEyepiece height (zenith) &#8211;\u00a0 1420 mm<\/p>\n<p><strong>Dimension:<\/strong><br \/>\nRocker box &#8211;\u00a0 45x45x320 mm (including the circular plate) x 5,2 Kg<br \/>\nMirror box &#8211;\u00a0 425x425x275 mm x 7,13 Kg.<br \/>\nUpper assembly &#8211;\u00a0 345&#215;200 mm x 2,8 Kg<br \/>\nTubes\u00a0\u00a0\u00a0\u00a0\u00a0 \u00a0 \u00a0\u00a0 &#8211;\u00a0 1,6 Kg.<br \/>\nCarton box \u00a0 &#8211;\u00a0 500x500x500 mm<\/p>\n<p><img loading=\"lazy\" src=\"http:\/\/www.geoptik.com\/image\/data\/Nadirus\/Nadirus 12.jpg\" alt=\"\" width=\"924\" height=\"258\" \/><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-size: 16px;\"><span style=\"color: #800000;\"><strong>WAT&#8217;S IN THE BOX<\/strong><\/span><\/span><\/p>\n<p><em><strong>1)\u00a0\u00a0\u00a0 ROCKER BOX (1)<br \/>\n2)\u00a0\u00a0\u00a0 CIRCULAR BASE PLATE (1)<br \/>\n3)\u00a0\u00a0\u00a0 MIRROR BOX (1)<br \/>\n4) \u00a0\u00a0 CELL<br \/>\n5)\u00a0\u00a0\u00a0 ALTITUDE BEARING (2)<br \/>\n6) \u00a0\u00a0 KNOBS FOR ALTITUDE BEARING (4)<br \/>\n7) \u00a0\u00a0 TRUSSES 20 mm (8)<br \/>\n8)\u00a0 \u00a0 <span id=\"result_box\" class=\"short_text\" lang=\"en\"><span class=\"hps\">BOLTS<\/span> <span class=\"hps\">AND WASHERS FOR TUBES (4+4)<\/span><\/span><br \/>\n9)\u00a0\u00a0\u00a0 BAG FOR TUBES<br \/>\n10) SECONDARY CAGE (1) <\/strong><\/em><br \/>\n<em><strong>11) SECONDARI MIRROR HOLDER &amp; SPIDER (1)<\/strong><\/em><br \/>\n<em><strong>12) LIGHT SHIELD<\/strong><\/em> <strong>FOR SECONDARY MIRROR CAGE<\/strong><\/p>\n<p><span style=\"font-size: 16px;\"><em><strong><span style=\"color: #800000;\">WHAT&#8217;S NOT IN THE BOX <\/span><\/strong><\/em><\/span><\/p>\n<p><em><strong>1)\u00a0\u00a0 PRIMARY MIRROR<br \/>\n2)\u00a0\u00a0 SECONDARY MIRROR<br \/>\n3) \u00a0 FOCUSER<br \/>\n4)\u00a0\u00a0 FINDERSCOPES<br \/>\n5)\u00a0\u00a0 LIGHT SHROUD <\/strong><\/em><br \/>\n6)\u00a0\u00a0 <em><strong>MAGNETIC COUNTERWEGHT AND PLATE<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dobsonian truss telescopes 12&#8243; (300 mm) This kit do not include the primary and secondary mirror, focuser and finderscope.
