Its focal length of <strong>800 mm<\/strong> and its parabolic primary mirror make it an instrument well-suited for imaging nebulae and galaxies. The <strong>The weight listed by Sky-Watcher is approximately 9.5 kg<\/strong>. It comes as a bare optical tube, without a mount.<\/p>\n<h3>A Bright Lens for Astrophotography<\/h3>\n<p>The Quattro-200P belongs to the 200-mm Newtonian class; Sky-Watcher lists the primary mirror diameter as <strong>205 mm<\/strong> for this version. Its aperture ratio <strong>f\/4<\/strong> is particularly well-suited for photographing faint deep-sky objects. The parabolic mirror is made of borosilicate glass with low thermal expansion. The interior of the tube features diaphragms designed to limit stray light and preserve image contrast.<\/p>\n<h3>A 10:1 zoom ratio<\/h3>\n<p>The eyepiece holder <strong>50.8 mm (2-inch) Crayford Linear Power<\/strong> features a 10:1 gear ratio for precise focusing. Its ball-bearing guide and tension adjustment allow its operation to be adapted to the installed equipment. Adapters for 50.8 mm and 31.75 mm accessories are included. A locking screw secures the position after focusing.<\/p>\n<h3>Weight, Size, and Choice of Frame<\/h3>\n<p>The steel tube has an outside diameter of <strong>23.5 cm<\/strong> and a reported length of <strong>71.1 cm<\/strong>. To determine the correct size for your frame, use the manufacturer's approximate weight of <strong>9.5 kg<\/strong>, then take into account any additional equipment: camera, corrector, filter wheel, and any guiding system. Check the load capacity suitable for astrophotography and make sure the entire setup is properly balanced, especially if you have heavy camera equipment mounted on the side of the tube.<\/p>\n<h3>Equipment Provided and Accessories to Bring<\/h3>\n<p>The tube is supplied with a <strong>9\u00d750 Right-Handed Scope<\/strong>, its mounting clamps, a Vixen-style dovetail, and a parallel camera mount. The finder scope makes it easier to point the telescope once it is aligned with the instrument. Visual observation is still possible with suitable eyepieces, which should be selected separately depending on the objects being observed and the desired magnification.<\/p>\n<p><strong>The mount, eyepieces, and coma corrector are not included.<\/strong> For astrophotography, be sure to include a corrector compatible with an f\/4 Newtonian telescope to correct the shape of stars at the edge of the field of view, as well as the rings needed for your camera. Also check the alignment of the mirrors and fine-tune the focus while the telescope warms up: these adjustments determine the quality of the images.<\/p>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>The <strong>Sky-Watcher Quattro-200P f\/4<\/strong> is a steel-tube Newtonian telescope designed for deep-sky astrophotography.
