A direct evolution of the famous Explorer-300P, this PDS (Photo Dual Speed) version incorporates major improvements that make it the instrument of choice for demanding astronomers wishing to capture images of the deep sky with great precision.<\/p>\n<p>This model retains the same <strong>305 mm parabolic primary mirror<\/strong> than its predecessor, guaranteeing impressive light-gathering capacity. With <strong>44% more light than a 250 mm telescope<\/strong>, With its long focal length, it reveals fine details of galaxies, nebulae and star clusters. Its long focal length of <strong>1500 mm (f\/4.9)<\/strong> offers an excellent compromise between wide field and resolution, particularly suited to deep-sky imaging.<\/p>\n<p>One of the main advantages of the EXPLORER-300PDS is its <strong>Crayford 2\u2033 double-speed eyepiece holder (10:1 ratio)<\/strong>. This system enables extremely precise focus adjustment, essential for astrophotography where perfect sharpness is essential. The fine gearing facilitates fine adjustments, even with high-resolution sensors.<\/p>\n<p>The optical tube has been <strong>slightly shortened<\/strong> compared to the standard version to optimize use in <strong>primary focus shooting<\/strong>. This design improves compatibility with a wide range of cameras and astronomical cameras, while making it easier to reach the focus point without additional accessories.<\/p>\n<p>The primary and secondary mirrors are treated <strong>Radiant\u2122 Aluminum Quartz (RAQ\u2122)<\/strong>, offering up to <strong>94% reflectivity<\/strong>. This coating guarantees excellent light transmission, greater durability and consistent performance over time. What's more, the secondary mirror supports are made of <strong>ultra-thin 0.5 mm handles<\/strong>, significantly reducing diffraction and improving image contrast.<\/p>\n<p>To get the most out of this instrument, we recommend that you use a <strong>Sky-Watcher coma corrector<\/strong>. This accessory corrects the optical distortions typical of fast Newton telescopes (f\/4.9), guaranteeing perfectly punctual stars across the entire field, an essential asset in astrophotography.<\/p>\n<p>The EXPLORER-300PDS is supplied with a <strong>28 mm LET (2\u2033) eyepiece<\/strong>, with a magnification of <strong>x53.5<\/strong>, ideal for wide-field observations. Its theoretical maximum power reaches <strong>x610<\/strong>, This allows you to explore the finest details in optimal conditions. A <strong>researcher 9\u00d750<\/strong> is also included to help locate celestial objects.<\/p>\n<p>The tube is supplied with <strong>sturdy clamps<\/strong> as well as a <strong>Losmandy-type dovetail<\/strong>, The telescope is compatible with heavy equatorial mounts capable of supporting this type of instrument. This telescope is particularly well suited to robust mounts for advanced astrophotography.<\/p>\n<p>Powerful, precise and optimized for imaging, the <strong>Sky-Watcher EXPLORER-300PDS<\/strong> has established itself as a benchmark for enthusiasts wishing to take their deep-sky observation and astrophotography skills to the next level.<\/p>\n<h3>Sky-Watcher EXPLORER-300PDS technical specifications<\/h3>\n<table border=\"1\" cellspacing=\"0\" cellpadding=\"8\">\n<tbody>\n<tr>\n<th>Features<\/th>\n<th>Detail<\/th>\n<\/tr>\n<tr>\n<td>Telescope type<\/td>\n<td>Newton Reflector<\/td>\n<\/tr>\n<tr>\n<td>Mirror diameter<\/td>\n<td>305 mm<\/td>\n<\/tr>\n<tr>\n<td>Focal length<\/td>\n<td>1500 mm<\/td>\n<\/tr>\n<tr>\n<td>Focus report<\/td>\n<td>f\/4.9<\/td>\n<\/tr>\n<tr>\n<td>Magnification supplied<\/td>\n<td>x53.5<\/td>\n<\/tr>\n<tr>\n<td>Maximum magnification<\/td>\n<td>x610<\/td>\n<\/tr>\n<tr>\n<td>Optical treatment<\/td>\n<td>RAQ\u2122 (up to 94% reflectivity)<\/td>\n<\/tr>\n<tr>\n<td>Mirror type<\/td>\n<td>Parabolic<\/td>\n<\/tr>\n<tr>\n<td>Lens holder<\/td>\n<td>Crayford 2\u2033 Dual-Speed 10:1<\/td>\n<\/tr>\n<tr>\n<td>Eyepiece included<\/td>\n<td>28 mm LET (2\u2033)<\/td>\n<\/tr>\n<tr>\n<td>Researcher<\/td>\n<td>9\u00d750<\/td>\n<\/tr>\n<tr>\n<td>Secondary mirror support<\/td>\n<td>Ultra-thin branches 0.5 mm<\/td>\n<\/tr>\n<tr>\n<td>Mounting<\/td>\n<td>Losmandy collars + dovetails<\/td>\n<\/tr>\n<tr>\n<td>Optimization<\/td>\n<td>Shortened tube for astrophotography<\/td>\n<\/tr>\n<tr>\n<td>Brightness gain<\/td>\n<td>+44% compared with 250 mm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>&nbsp; Sky-Watcher EXPLORER-300PDS : t\u00e9lescope Newton 305 mm haute performance pour astrophotographie et observation Le Sky-Watcher EXPLORER-300PDS est un t\u00e9lescope Newton de grand diam\u00e8tre con\u00e7u pour offrir des performances exceptionnelles en astrophotographie comme en observation visuelle. \u00c9volution directe du c\u00e9l\u00e8bre Explorer-300P, cette version PDS (Photo Dual Speed) int\u00e8gre des am\u00e9liorations majeures qui en font un [&hellip;]<\/p>\n","protected":false},"featured_media":13974,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[822],"product_cat":[15,747,392],"product_tag":[],"class_list":["post-13973","product","type-product","status-publish","has-post-thumbnail","product_brand-sky-watcher","product_cat-non-classe","product_cat-newton","product_cat-telescopes_reflecteurs","first","on_supplier","taxable","shipping-taxable","purchasable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/deep-space-astronomy.ch\/en\/wp-json\/wp\/v2\/product\/13973","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/deep-space-astronomy.ch\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/deep-space-astronomy.ch\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/deep-space-astronomy.ch\/en\/wp-json\/wp\/v2\/comments?post=13973"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/deep-space-astronomy.ch\/en\/wp-json\/wp\/v2\/media\/13974"}],"wp:attachment":[{"href":"https:\/\/deep-space-astronomy.ch\/en\/wp-json\/wp\/v2\/media?parent=13973"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/deep-space-astronomy.ch\/en\/wp-json\/wp\/v2\/product_brand?post=13973"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/deep-space-astronomy.ch\/en\/wp-json\/wp\/v2\/product_cat?post=13973"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/deep-space-astronomy.ch\/en\/wp-json\/wp\/v2\/product_tag?post=13973"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
