The moon looks surprisingly good, and bright planets are visible at their largest. During the day, the diagonal prism turns it into a powerful nature viewer for birds and landscapes.<\/p>\n<h2>Rich Field: Heaven on a Grand Scale<\/h2>\n<p>Star travel refractors are built for broad use: short focal length, wide field of view, and plenty of light per observation. Entire constellations, vast star fields, the Pleiades in one view, and comet hunting: that's their territory. With an erect image diagonal, they also make excellent daytime binoculars. One thing they are intentionally not: high-magnification planet specialists.<\/p>\n<h2>This is how to get the most out of this telescope<\/h2>\n<ul>\n<li><strong>Ready in ten minutes:<\/strong> A refractor lens has hardly any cooldown time, and the closed tube means no collimation. Set up and look.<\/li>\n<li><strong>Know what a fast achromat is:<\/strong> At f\/5, you'll see a distinct purple-blue edge around bright objects like Venus, Sirius, and the moon's edge. This is hardly noticeable in wide star fields, for which this lens was made; for high magnifications and photography, you'd choose an ED refractor. That's the honest agreement behind this price.<\/li>\n<li><strong>Look up at the dark sky<\/strong> Correct, widefield viewing gains immensely with low light pollution; this is an excellent telescope to take along.<\/li>\n<li><strong>Magnification:<\/strong> het 10 mm oculair geeft 50x; het brede veld is het punt van deze buis, niet de hoge vergroting.<\/li>\n<li><strong>Never look directly at the sun without protection.,<\/strong> not even for a moment: only with a certified solar filter on the front.<\/li>\n<\/ul>\n<h2>For whom yes and for whom no<\/h2>\n<p><strong>Hello<\/strong> wie al een montering heeft en er het brede hemelbeeld naast wil zetten.<\/p>\n<p><strong>Not<\/strong> For high-magnification planet detail, a Maksutov or long refractor is the better choice, and deep-sky photography suits an ED refractor or the <a href=\"https:\/\/www.telescoop.nl\/en\/telescopes\/smart-telescopes\/\">smart telescopes<\/a>.
