De 2 inch Crayford draagt groothoekoculairs en camera&#8217;s, de 1,25\/2 inch adapter en red dot-zoeker zitten erbij.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On an EQ5-class mount, this is a complete visual and photographic setup for years to come.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Included<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Newtonian optics 203\/1000 with BK7 mirror (94 percent reflection)<\/li>\n\n\n<li>Metal tube<\/li>\n\n\n<li>2-inch Crayford focuser with 1.25\/2-inch adapter<\/li>\n\n\n<li>Red dot sight<\/li>\n\n\n<li>Tube rings with Vixen-style dovetails<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Featured accessories<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The Omegon laser collimator (44.90 euros) keeps the mirrors aligned; with every Newtonian, one belongs in the drawer. An Omegon 13 percent moon filter (27.90 euros) is practically mandatory for an 8-inch. The Omegon Pro UHC 2-inch filter (89 euros) brings out nebulae and the Omegon Cronus 7 mm eyepiece (79 euros) provides 143x magnification for planets.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">For whom yes, for whom no<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Pros: advanced observers with a sturdy mount who want the classic 8-inch Newtonian as an optical tube. Cons: those who do not have a mount and observe visually; the Advanced X 203 Dobson offers the same aperture class complete for the same money.
