You will find this design between the <a href=\"https:\/\/www.telescoop.nl\/en\/telescopes\/catadioptric-telescopes\/\">catadioptric telescopes<\/a>. This set is intended for 6 inch SNTs, so please check beforehand whether your telescope has that size and build.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Good collimation is important for sharp stars in a Newtonian design.
