Met 120 mm triplet-opening komen kleinere sterrenstelsels en planetaire nevels fotografisch binnen bereik, terwijl het beeld ook bij hoge vergroting visueel strak blijft.

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>Voor de fijnere doelen<\/h2>\n<p>Op 840 mm brandpunt vullen bolhopen en compacte nevels de sensor, en de triplet-correctie houdt de sterren ook op grote sensoren strak. De meegeleverde 2 inch star diagonal en zoeker maken visueel gebruik direct mogelijk: planeten door 120 mm kleurzuiver glas zijn een belevenis op zich.<\/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 EQ6-klasse montering is het advies: 120 mm triplet met camera is een serieuze last.<\/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>Visually pleasing as well:<\/strong> op 140x (met een 6 mm oculair) tonen planeten zich kleurzuiver en gestoken scherp.<\/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 gevorderde fotograaf die naar de fijnere, kleinere doelen wil, met visueel planeetwerk als volwaardige tweede rol.<\/p>\n<p><strong>Not<\/strong>  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<li><strong>A 6mm planetary eyepiece:<\/strong> the <a href=\"https:\/\/www.telescoop.nl\/en\/sky-watcher-6-mm-planetary-uwa-eyepiece-58-125\/\">Sky-Watcher 6mm Planetary UWA Eyepiece<\/a> geeft 140x voor visueel planeetwerk.<\/li>\n<\/ul>\n<h2>Technical specifications<\/h2>\n<table class=\"has-fixed-layout\">\n<thead>\n<tr>\n<th>Feature<\/th>\n<th>Value<\/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>120<\/td>\n<\/tr>\n<tr>\n<td>Focal length (mm)<\/td>\n<td>840<\/td>\n<\/tr>\n<tr>\n<td>Aperture ratio (f\/)<\/td>\n<td>7<\/td>\n<\/tr>\n<tr>\n<td>Resolution<\/td>\n<td>0,96<\/td>\n<\/tr>\n<tr>\n<td>Limit value (mag)<\/td>\n<td>12,2<\/td>\n<\/tr>\n<tr>\n<td>Light output<\/td>\n<td>290<\/td>\n<\/tr>\n<tr>\n<td>Max. useful magnification<\/td>\n<td>240<\/td>\n<\/tr>\n<tr>\n<td>Tube weight (kg)<\/td>\n<td>9,61<\/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>Lens design<\/td>\n<td>Triplet<\/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-120-840-ESPRIT-120ED-Apochromatische-Refractor-Professional-OTA-3.jpg\" alt=\"Sky-Watcher Esprit-120ED apochromatische triplet refractor, productfoto 2\" class=\"wp-image-90881\" 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-120ED optische buis<\/li>\n<li>Oculair: LET 28 mm<\/li>\n<li>Searcher: 9x50<\/li>\n<li>Star diagonal: 2\u2033, 90\u00b0<\/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.
