They are often purchased for beginner due to their simplicity and ease of use. Dobsonian telescopes are designed for visual observing. GSO Dobsonians have better coating and high quality mirrors for maximum success and fun under the skies. Its cost\/performance ratio is truly unbeatable.<\/li>\n<li><strong>Excellent Visual Performance:<\/strong>\u00a0For best possible image quality you need high quality optics as well as optimized mechanics. The GSO Dobsonian has both. The thin spider vanes improve contrast and image sharpness compared with a simpler spider with thick vanes. The 94% enhanced coating on main mirror and secondary mirror produces a brighter image. Save up to 10% light against other telescopes with same aperture.<\/li>\n<li><strong>Grab-And-Go Setup:<\/strong>\u00a0The simple and intuitive way to use this telescope makes it much easier for beginners to spend their first joyful hours under the starry sky. Set-up is as easy as you can imagine: just put the rocker box on the ground, insert the telescope tube and put the springs in position and you\u00b4re ready to go!<\/li>\n<li><strong>Primary Mirror Cooling Fan:<\/strong>\u00a0Until a mirror is properly cooled down it will create currents of warm air that will deteriorate the image \u2013 no matter which mirror substrate is used. Only after the mirror has cooled down this effect stops. The cooling fan reduces the cooling down time.<\/li>\n<li><strong>Upgrade your Dobsonian:<\/strong>\u00a0A Dobsonian telescope from GSO is a perfect starter telescope. You will get a high end optic for an incredible low price. Later you can upgrade the telescope with eyepieces, filters or with cradle rings to mount it upon a parallactic mount. Than you also can start with astrophotography through your Newtonian telescope.<\/li>\n<li><strong>Optical performance:<\/strong>\u00a0The telescope is equipped with high quality GSO mirrors. The selected main mirror is better, than diffraction limited. We always make optical tests on our optical bench to guarantee the high optical level of GSO Newtonians and Dobsonians.<\/li>\n<li><strong>The 2\u2033 Crayford Focuser:<\/strong>\u00a0A central part of the telescope is the good 2\u2033Crayford focuser with many advantages:<\/li>\n<li><em>Much smoother focus motion compared with simpler focusers.<\/em><\/li>\n<li><em>Secure and scratch-free grip on the eyepieces through use of a brass compression ring (both 1.25\u2033 and 2\u2033)<\/em><\/li>\n<li><em>No image shift. This means that the object will remain precisely in position while you focus. Simpler focusers tend to be shifted a little bit out of alignment, resulting in a relative movement of the object. This somewhat annoying effect does not occur in the Crayford focuser.<\/em><\/li>\n<li><em>No play when you reverse the focusing direction. The focuser will reverse the direction in which it moves instantaneously when you change the direction in which you turn the focus knobs<\/em>.<\/li>\n<li>Centering and Tracking Objects with the GSO Classic Dobsonian<\/li>\n<li>The mount of a Dobsonian telescope is called \u201c\u201dRocker-Box\u201d\u201d, a fitting name for the uniquely simple and well-working design.<\/li>\n<li>The rocker allows you to point the telescope at any point in the sky and allows for comfortable, intuitive movement. Moving the telescope is very simple, just push the telescope into the right direction ? no need to use clamps or motors, it doesn\u2019t get more simple than this! Since you need to move the Dobsonian manually it is particularly important that the movement be as smooth as possible. The Dobsonian has an azimuth roller bearing for smooth operation<\/li>\n<li>For the elevation, the telescope is equipped with the Spring Tension System. This prevents the telescope from moving for example when exchanging eyepieces.<\/li>\n<\/ul>\n","protected":false},"featured_media":118,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[24,17],"product_tag":[37,38,28],"class_list":{"0":"post-117","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-reflector-telescope","7":"product_cat-telescope","8":"product_tag-gso-8-dobsonian-telescope","9":"product_tag-reflector","10":"product_tag-telescope","12":"first","13":"instock","14":"taxable","15":"shipping-taxable","16":"purchasable","17":"product-type-simple"},"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/buytelescope.in\/index.php?rest_route=\/wp\/v2\/product\/117","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/buytelescope.in\/index.php?rest_route=\/wp\/v2\/product"}],"about":[{"href":"https:\/\/buytelescope.in\/index.php?rest_route=\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/buytelescope.in\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=117"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/buytelescope.in\/index.php?rest_route=\/wp\/v2\/media\/118"}],"wp:attachment":[{"href":"https:\/\/buytelescope.in\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=117"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/buytelescope.in\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_brand&post=117"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/buytelescope.in\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_cat&post=117"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/buytelescope.in\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_tag&post=117"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
