Met f\/5 verzamel je in de helft van de tijd wat een f\/7-buis nodig heeft: op een Nederlandse hemel met beperkte heldere uren telt dat zwaar.<\/p>\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/12\/Skywatcher-AP-80-400-ESPRIT-80ED-Apochromatische-Refractor-Professional-OTA-2.jpg\" alt=\"Sky-Watcher Esprit-80ED apochromatische triplet refractor\" class=\"wp-image-90892\" title=\"\"><\/figure>\n<h2>Why an Esprit?<\/h2>\n<p>The Esprit line is Sky-Watcher's professional astrophotography series: air-spaced triplets with premium glass, built to place flat, color-pure star fields onto a camera sensor. Stars remain points even in the corners, even with large sensors, and bright stars do not develop a purple halo. This is the class where optics make the difference between a nice and a publishable photo.<\/p>\n<h2>Snel glas, complete uitrusting<\/h2>\n<p>De set bevat een 9x50 hoekzoeker en een 2 inch star diagonal, zodat de buis ook visueel direct inzetbaar is. Fotografisch is f\/5 met triplet-correctie een krachtige combinatie: veel signaal per minuut en sterren die punten blijven.<\/p>\n<h2>This is how to get the most out of this telescope<\/h2>\n<ul>\n<li><strong>Virtually no cooling time and no collimation:<\/strong> A refractor is ready within fifteen minutes, and the optics stay aligned. More time for photons.<\/li>\n<li><strong>The setup determines your photo result:<\/strong> een Star Adventurer GTi kan met lichte camera's; een HEQ5-klasse montering geeft comfort en groeiruimte.<\/li>\n<li><strong>Plan to flatten me:<\/strong> For sharp stars all the way to the corners of your sensor, a field flattener is essential for a photographic refractor. Order it along with your initial purchase to avoid a second waiting period.<\/li>\n<li><strong>Dew control is essential with lenses:<\/strong> A dew cap or dew heater prevents the front lens from fogging up in the middle of a session.<\/li>\n<li><strong>Never look directly at the sun without protection.,<\/strong> not even for one photo: only with a certified solar filter in front.<\/li>\n<\/ul>\n<h2>For whom yes and for whom no<\/h2>\n<p><strong>Hello<\/strong> de serieuze deep-sky-fotograaf die een snelle, compacte astrograaf zoekt voor de grote nevelvelden.<\/p>\n<p><strong>Not<\/strong> Voor planeetfotografie of hoge vergrotingen is het brandpunt te kort; Wil je astrofotografie zonder montering-leercurve en nabewerking, dan zijn de <a href=\"https:\/\/www.telescoop.nl\/en\/telescopes\/smart-telescopes\/\">smart telescopes<\/a> the shorter route; ours <a href=\"https:\/\/www.telescoop.nl\/en\/the-best-telescope-for-beginners\/\">Telescope Buying Guide for Beginners<\/a> explain the difference.<\/p>\n<h2>Featured accessories<\/h2>\n<p>These accessories add the most after purchase:<\/p>\n<ul>\n<li><strong>Camera adapter:<\/strong> The Sky-Watcher M48 adapters connect your Canon EOS or Nikon directly to the flattener or focuser.<\/li>\n<li><strong>Light Pollution Filter (2 inch)<\/strong> Under the Dutch or Belgian sky, a light pollution filter can significantly enhance the contrast in your photos.<\/li>\n<\/ul>\n<h2>Technical specifications<\/h2>\n<table class=\"has-fixed-layout\">\n<thead>\n<tr>\n<th>Feature<\/th>\n<th>Description<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Type<\/td>\n<td>Refractor<\/td>\n<\/tr>\n<tr>\n<td>Design<\/td>\n<td>Apochromat<\/td>\n<\/tr>\n<tr>\n<td>Aperture (mm)<\/td>\n<td>80<\/td>\n<\/tr>\n<tr>\n<td>Focal length (mm)<\/td>\n<td>400<\/td>\n<\/tr>\n<tr>\n<td>Focal Ratio (f\/)<\/td>\n<td>5<\/td>\n<\/tr>\n<tr>\n<td>Resolution<\/td>\n<td>1,44\u2033<\/td>\n<\/tr>\n<tr>\n<td>Limit value (mag)<\/td>\n<td>11,3<\/td>\n<\/tr>\n<tr>\n<td>Light output<\/td>\n<td>130\u00d7<\/td>\n<\/tr>\n<tr>\n<td>Max. useful magnification<\/td>\n<td>160\u00d7<\/td>\n<\/tr>\n<tr>\n<td>Lens Design<\/td>\n<td>Triplet<\/td>\n<\/tr>\n<tr>\n<td>Tube material<\/td>\n<td>Aluminum<\/td>\n<\/tr>\n<tr>\n<td>Tube construction<\/td>\n<td>Full tube<\/td>\n<\/tr>\n<tr>\n<td>Tube weight (kg)<\/td>\n<td>3,97<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<div class=\"wp-block-columns is-layout-flex\">\n<div class=\"wp-block-column\" style=\"flex-basis:38%\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/12\/Skywatcher-AP-80-400-ESPRIT-80ED-Apochromatische-Refractor-Professional-OTA-4.jpg\" alt=\"Sky-Watcher Esprit-80ED apochromatische triplet refractor, productfoto 2\" class=\"wp-image-90894\" title=\"\"><\/figure>\n<\/div>\n<div class=\"wp-block-column\" style=\"flex-basis:62%\">\n<h2>Included in the box<\/h2>\n<ul>\n<li>Sky-Watcher Esprit-80ED optische buis<\/li>\n<li>Zoeker: 9\u00d750 hoekzoeker<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<h2>Honest advice from observers<\/h2>\n<p>We sell and use the Sky-Watcher line ourselves.
