It mounts on a 1.25-inch barrel and has a 10-mm eye relief. This configuration is suitable for observing star clusters, compact deep-sky objects, and general-purpose observing, depending on your telescope\u2019s focal length.<\/p>\n<h3>What is this model best suited for?<\/h3>\n<p>The Pl\u00f6ssl formula provides a way to design a range of magnifications without seeking an extreme apparent field of view. Pay particular attention to the eye relief: it varies with the focal length and determines the position of the eye.<\/p>\n<ul>\n<li>The manufacturer intends these focal lengths for deep-sky and planetary observation and recommends using them in combination with Powermates.<\/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>EAP-15.0<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Family<\/th>\n<td>Pl\u00f6ssl<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Focal length<\/th>\n<td>15 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>12.6 mm<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Weight<\/th>\n<td>0.16 lb \/ 2.6 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, this eyepiece provides approximately 67\u00d7 magnification. The magnification is calculated by dividing the telescope\u2019s focal length by that of the eyepiece.<\/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<p><strong>Is the apparent field the field visible in the sky?<\/strong><br \/>No. The apparent field of view of 50\u00b0 describes the view through the eyepiece. The actual field of view depends on the telescope; the 12.6-mm field stop is the value to use to calculate it.<\/p>\n<h3>Before Ordering<\/h3>\n<p>Check the focus range, the focus travel, the maximum weight your setup can support, and the compatibility of filters or correctors.
