This allows you to see exactly how the secondary and primary mirrors are aligned, and to adjust both step-by-step.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No batteries, no electronics, nothing that can expire: a Cheshire is always well aligned itself. Many observers combine it with a laser collimator: the Cheshire for the secondary mirror and the check, the laser for quick primary mirror correction in the field.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Features<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li>Classic, battery-free collimation method<\/li>\n\n\n<li>Suitable for secondary and primary mirror alignment<\/li>\n\n\n<li>1.25-inch mount<\/li>\n\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Suitable for Newtonian telescopes; also useful for checking refractor alignment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Specifications<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Type<\/strong><\/td><td>Cheshire eyepiece<\/td><\/tr><tr><td><strong>Mount<\/strong><\/td><td>1.25 inches<\/td><\/tr><tr><td><strong>Nutrition<\/strong><\/td><td>None (optical)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The disassembly of <a href=\"https:\/\/www.telescoop.nl\/en\/brands\/sky-watcher\/\">Sky-Watcher<\/a> is a base that will last you for years.
