Open star clusters, the Milky Way, and the Moon appear at the push of a button in a wide field of view.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Fast achromatic lens for overview<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The 90mm lens captures approximately 165 times more light than the naked eye and shows a wide expanse of sky in one image at low magnification. Honest advice: this fast double-lens design shows color fringing on bright objects at high magnification; it's an overview viewer, not a planetary specialist.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">StarTracker GoTo System<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The StarTracker hand controller knows over 100,000 objects and automatically positions the telescope. Servo motors on both axes then track accurately, and you can later connect an autoguider via the ST-4 port. The EXOS-2 GoTo can carry up to 13 kg. For this light tube, that payload capacity is generous: vibration-free viewing guaranteed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Included<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Achromatic optics 90\/500<\/li>\n\n\n\n<li>EXOS-2 GoTo Mount with StarTracker Hand Controller<\/li>\n\n\n\n<li>Tripod<\/li>\n\n\n\n<li>Eyepiece and viewfinder<\/li>\n\n\n\n<li>Zenith prism<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Featured accessories<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/www.telescoop.nl\/en\/bresser-eyepiece-plossl-pl-10mm-125\/\">Bresser Pl\u00f6ssl 10 mm eyepiece<\/a> (50x, 29 euros) zooms in on star clusters. The Bresser universal power supply 230V\/12V (39 euros) powers the mount at home; the Bresser Mobile Power Station 155 Wh (169 euros) keeps it running in the field all night. An Omegon Premium moon filter (19.90 euros) dims the moonlight.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">For whom yes, for whom no<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Good for: those who want to explore star fields and the Moon without extensive searching. Not for: planet observers and those who would rather spend this budget on a <a href=\"https:\/\/www.telescoop.nl\/en\/telescopes\/smart-telescopes\/\">smart telescope<\/a> stick; compare both routes first.
