It mounts on a 2-inch slip-on adapter and has an eye relief of 27 mm. This configuration is worth considering for star fields and extended deep-sky objects, depending on your instrument\u2019s focal length.<\/p>\n<h3>What is this model best suited for?<\/h3>\n<p>The Panoptic series combines an apparent field of view of 68\u00b0 with focal lengths designed for wide-angle views. It allows you to locate an object within its stellar environment, while maintaining an apparent field of view that is narrower than that of a Nagler or an Ethos.<\/p>\n<ul>\n<li>46-mm diaphragm for the maximum advertised real field of 2 inches; adjustable and removable screw-on top section.<\/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>EPN-41.0<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Family<\/th>\n<td>Panoptic<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Focal length<\/th>\n<td>41 mm<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Apparent field<\/th>\n<td>68\u00b0<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Flow<\/th>\n<td>2 inches<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Eye Discharge<\/th>\n<td>27 mm<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Field diaphragm<\/th>\n<td>46 mm<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Weight<\/th>\n<td>2.1 lb \/ 33.6 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 24\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 requires a 2-inch eyepiece holder or a 2-inch right-angle mirror. It cannot be inserted directly into a 1.25-inch mount. Also check that it is securely fastened and properly balanced.<\/p>\n<p><strong>Can you observe things with glasses?<\/strong><br \/>The specified eye relief is 27 mm. Comfort when wearing glasses also depends on the shape of the glasses and the position of the eye; trying them on is always better than relying on a universal guarantee. The Tele Vue chart indicates DIOPTRX compatibility; this astigmatism corrector is optional.<\/p>\n<p><strong>Is the apparent field the field visible in the sky?<\/strong><br \/>No. The apparent field of view of 68\u00b0 describes the view through the eyepiece. The actual field of view depends on the telescope; the 46-mm field stop is the value to use to calculate it.<\/p>\n<h3>Before Ordering<\/h3>\n<p>Check the focus travel, the focus range, the weight your mount can support, and the compatibility of filters or correctors.
