Thanks to its unique design, there's no need to add field correctors or calculate back focus. Simply equip the 65PHQ with the accessories of your choice, aim at your target, and let optical precision do the rest.\n<\/p>\n<p>\nThe focal length of this small 65mm lens is ideal for detailing the structures of nebulae and galaxies. Its relatively open aperture ratio (f\/d) allows modern cameras to rapidly gather light without any problem. You soon find yourself with an easy-to-use instrument, offering superb detail and foolproof handling. It's a very interesting choice, all the more so as with the reducer you almost get a second, more open instrument (smaller f\/d = more light collected in equivalent time), enabling you to focus on other objects.\n<\/p>\n<h3>Exceptional Performance and Precision<\/h3>\n<p>\nThe 65PHQ has a 65mm aperture and a focal length of 416mm, with a focal ratio of f\/6.4. Its quintuplet structure, incorporating two ED lenses, offers outstanding control of chromatic aberrations and other distortions, ensuring images of exceptional quality. This \"self-correcting\" design supports the full-frame image circle while minimizing peripheral star distortion - perfect for capturing the finest details of the cosmos.\n<\/p>\n<h3>Technical specifications<\/h3>\n<ul>\n<li>Opening: 65 mm<\/li>\n<li>Focal length: 416 mm<\/li>\n<li>Design: Quintuplet with ED lenses, supports full format<\/li>\n<li>Central RMS radius: 2.5 \u03bcm for sharp, precise images<\/li>\n<li>Weight: Tube only 2 kg, complete set with accessories 2.8 kg<\/li>\n<li>Focusing: 2.5-inch rigid mechanism with 360\u00b0 rotator and 1:10 fine adjustment<\/li>\n<\/ul>\n<h3>Designed for Astrophotography and Visual Observation<\/h3>\n<p>\nThe 65PHQ offers excellent performance for visual observation. Its advanced optical system ensures perfect focus, whether for observing distant galaxies or the planets of our solar system at high magnification. The very idea of being able to use this astrograph as a multi-purpose instrument, even if you just want to have a quick look at the Moon with friends, makes it a real asset.\n<\/p>\n<h3>Accessories and Compatibility<\/h3>\n<p>\nThe 65PHQ comes with a range of accessories to make your experience easier:\n<\/p>\n<ul>\n<li>Retractable sunshade<\/li>\n<li>Multifunctional handle and 300 mm Vixen dovetail plate for secure mounting<\/li>\n<li>Camera adapters: M68, M54 and M48 included, plus adapter for 2\" filters<\/li>\n<li>Optional 0.75x gearbox for greater flexibility<\/li>\n<\/ul>\n<p>\nTake advantage of multiple connection options with M68x1, M54x0.75, and M48x0.75 back threads (with filter thread). For both astrophotography and observation, the 65PHQ offers fast, reliable connection and maximum accessory range:\n<\/p>\n<ul>\n<li>Imaging mode: up to 130 mm<\/li>\n<li>Observation mode: up to 121 mm<\/li>\n<\/ul>\n<h3>A complete package for all your experiences<\/h3>\n<ul>\n<li>Optical tube (OTA) 65PHQ<\/li>\n<li>Pair of sturdy fastening rings<\/li>\n<li>Multifunctional handle<\/li>\n<li>300 mm Vixen dovetail plate<\/li>\n<li>Adapter kit for photography<\/li>\n<li>Detailed user manual<\/li>\n<\/ul>\n<h3>Lightweight and portable<\/h3>\n<p>\nCompact, lightweight and easy to carry, the 65PHQ is the ideal companion for all your observing outings and astrophotography sessions. Whether you're in the field or in your observatory, it meets your needs for performance and mobility.\n<\/p>\n<h3>Conclusion<\/h3>\n<p>\nDiscover the power of the 65PHQ and capture astronomical images of uncompromisingly exceptional quality.
