It mounts on a 1.25-inch focuser and has an eye relief of 10 mm. This configuration is worth considering for lunar and planetary details and double stars, when the telescope\u2019s diameter and atmospheric turbulence permit.<\/p>\n<h3>What is this model best suited for?<\/h3>\n<p>The Nagler Zoom allows you to adjust the magnification without changing the eyepiece. The range of 3 to 6 mm is suitable for finding the magnification that the instrument and atmospheric turbulence actually allow you to use. The apparent field of view remains at 50\u00b0 across the entire adjustment range.<\/p>\n<ul>\n<li>3\u20136 mm zoom lens with markings at every millimeter; 50\u00b0 apparent field of view and 10 mm eye relief.<\/li>\n<\/ul>\n<h3>Technical specifications<\/h3>\n<table style=\"width:100%;border-collapse:collapse\">\n<tbody>\n<tr>\n<th scope=\"row\">Manufacturer reference<\/th>\n<td>ENZ-0306<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Family<\/th>\n<td>Nagler Zoom<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Focal length<\/th>\n<td>3\u20136 mm<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Apparent field<\/th>\n<td>50\u00b0<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Flow<\/th>\n<td>1.25 inches<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Eye Discharge<\/th>\n<td>10 mm<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Field diaphragm<\/th>\n<td>5.1\u20132.6 mm<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Weight<\/th>\n<td>0.33 lb \/ 5.3 oz<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Frequently asked questions<\/h3>\n<p><strong>What is the magnification with this eyepiece?<\/strong><br \/>With a telescope that has a focal length of 1,000 mm, the range from 6 mm to 3 mm provides a magnification of approximately 167\u00d7 to 333\u00d7.<\/p>\n<p><strong>Is it compatible with my telescope?<\/strong><br \/>It uses a 1.25-inch mount. In a 2-inch eyepiece holder, a suitable adapter is required. The ability to focus also depends on the optical path of the accessories.<\/p>\n<p><strong>Can you observe things with glasses?<\/strong><br \/>The advertised eye relief is 10 mm. Comfort when wearing glasses also depends on their shape and the position of the eye; trying them on is always better than relying on a universal guarantee.<\/p>\n<h3>Before Ordering<\/h3>\n<p>Check the focus travel, the focus range, the weight your setup can support, and the compatibility of filters or correctors.
