With the 26mm eyepiece, you get 35x magnification; consider around 180x as the maximum. At f\/10, chromatic aberration is well under control. Use solar filters only if they are undamaged, and never look at the sun without certified protection.<\/p>\n<\/div>\n<\/div>\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 positions the telescope automatically. 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.<\/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\/900<\/li>\n\n\n\n<li>EXOS-2 GoTo Mount with StarTracker Hand Controller<\/li>\n\n\n\n<li>Stainless steel tripod<\/li>\n\n\n\n<li>26mm eyepiece (1.25 inch)<\/li>\n\n\n\n<li>6\u00d730 viewfinder<\/li>\n\n\n\n<li>90 degree star diagonal<\/li>\n\n\n\n<li>Solar filters<\/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> (90x, 29 euros) is the medium magnification.
