With its unobstructed objective, pressure-adjustable internal etalon, and 900 mm focal length, it offers exceptional contrast, sharpness, and resolution for prominences, filaments, active regions, spicules, and surface details.<\/p>\n<p>This configuration, offered by Deep Space Astronomy, includes the particularly comprehensive version with <strong>B1800 blocking filter with 2\u2033 elbow fitting<\/strong>, <strong>Focuser Rack &amp; Pinion 2\u2033<\/strong>, <strong>Lunt 7.2\u201321.5 mm zoom eyepiece<\/strong> and <strong>Internal Double Stack module<\/strong>.<\/p>\n<h3>Configuration included<\/h3>\n<ul>\n<li><strong>Lunt LS152THa Solar Telescope<\/strong> \u2013 152 mm f\/6, 900 mm focal length<\/li>\n<li><strong>B1800 blocking filter<\/strong> with a 2\u2033 elbow<\/li>\n<li><strong>2-inch Rack &amp; Pinion Adjustment<\/strong><\/li>\n<li><strong>Internal Double Stack Module<\/strong> for LS130\/LS152<\/li>\n<li><strong>Lunt 7.2\u201321.5 mm Zoom Eyepiece<\/strong><\/li>\n<li>Clamps, dovetail joints, plugs, and a reinforced carrying case<\/li>\n<\/ul>\n<h3>Why choose the B1800 version?<\/h3>\n<p>Visit <strong>B1800<\/strong> is an excellent choice for this diameter. It offers a more comfortable field of view than the B1200 and is better suited for mixed uses <strong>visual observation + solar imaging<\/strong>. It allows you to fully harness the LS152THa's potential with greater ease, particularly when using solar cameras or higher magnifications.<\/p>\n<h3>The Benefits of the Double Stack<\/h3>\n<p>The module <strong>Double Stack<\/strong> reduces bandwidth to approximately <strong>&lt; 0.5 \u00c5<\/strong>, which greatly increases the contrast on the solar disk. Filaments, active regions, fibrils, and surface structures become more pronounced, resulting in a richer and more spectacular image than a simple stack.<\/p>\n<p>This is the ideal setup for discerning observers looking for a high-contrast H-alpha image without sacrificing the resolution provided by the 152 mm aperture.<\/p>\n<h3>Doppler True Tuning Pressure Adjustment<\/h3>\n<p>The system <strong>Pressure Tuner<\/strong> The Lunt system allows for precise adjustment of the H-alpha filter. It adjusts the internal pressure to optimize transmission at the H-alpha line at 656.28 nm. This system makes it possible to bring out various solar structures\u2014including filaments and active regions\u2014with great detail.<\/p>\n<h3>Key features<\/h3>\n<ul>\n<li><strong>Type :<\/strong> dedicated H-alpha solar telescope<\/li>\n<li><strong>Opening :<\/strong> 152 mm<\/li>\n<li><strong>Focal length :<\/strong> 900 mm<\/li>\n<li><strong>Focal report :<\/strong> f\/6<\/li>\n<li><strong>Standard:<\/strong> internal, pressure-controlled<\/li>\n<li><strong>Bandwidth :<\/strong> &lt; 0.45 \u00c5 in a single stack<\/li>\n<li><strong>Blocking filter:<\/strong> B1800 with 2\u2033 Elbow Joint<\/li>\n<li><strong>Focus:<\/strong> 2-inch Rack and Pinion<\/li>\n<li><strong>Weight :<\/strong> about 13.6 kg<\/li>\n<\/ul>\n<h3>For which user?<\/h3>\n<p>The Lunt LS152THa is designed for advanced enthusiasts, observatories, astronomy clubs, and solar imagers who want a top-of-the-line H-alpha solution.
