Ideal for both beginners and experienced observers looking for an auxiliary instrument, this model combines proven optics with an innovative mount capable of equatorial or azimuthal operation.<\/p>\n<p>The \u00ab <em>grab-and-go<\/em> \u00bbThe STARQUEST-90MC is easy to install, quick to set up and simple to use, making it ideal for spontaneous observations of the night sky. Its compact design also makes it an excellent choice for travelling, without compromising on image quality.<\/p>\n<p>At the heart of this system is a telescope <strong>Maksutov-Cassegrain 90 mm diameter<\/strong>, renowned for its high optical performance. Its long focal length of <strong>1250 mm (f\/13.88)<\/strong> provides high magnification and excellent resolution, making it particularly effective for observing <strong>lunar details, planets and double stars<\/strong>. Thanks to its fully <strong>multi-processed<\/strong>, contrast is improved and images are sharper and brighter.<\/p>\n<p>The primary and secondary mirrors feature the exclusive <strong>Radiant\u2122 Aluminum Quartz (RAQ\u2122)<\/strong>guaranteeing <strong>reflectivity up to 94%<\/strong>. This treatment not only ensures excellent light transmission, but also great durability over time, enabling optimum performance to be maintained over the long term.<\/p>\n<p>STARQUEST-90MC offers light-gathering capability <strong>26.5% higher than an 80 mm telescope<\/strong>, This means brighter, more detailed images. It comes with two <strong>10 mm and 20 mm<\/strong>, which can achieve magnifications of <strong>x62.5 and x125<\/strong>. Its theoretical maximum power of <strong>x180<\/strong> makes it possible to explore celestial objects in even greater depth, under ideal observation conditions.<\/p>\n<p>The STARQUEST frame is another highlight of this set. Designed with a <strong>high-quality clutch system<\/strong>, it has a <strong>122-tooth, 360\u00b0 precision gearing<\/strong> on each axis. This guarantees smooth, precise and jerk-free movements. In equatorial mode, after polar alignment, you can easily track celestial objects with the <strong>slow-motion commands on right ascension (RA) and declination (DEC) axes<\/strong>.<\/p>\n<p>This feature is particularly useful for prolonged observation of the planets or as an introduction to astrophotography. In azimuth mode, the mount becomes even more intuitive, offering a quick and accessible grip, ideal for beginners or occasional use.<\/p>\n<p>With a maximum load capacity of <strong>3 kg<\/strong>, the frame provides excellent stability, reinforced by a <strong>adjustable aluminium tripod<\/strong> sturdy and lightweight. It features a practical accessory tray to keep eyepieces and other equipment close at hand. A <strong>counterweight bar with mass<\/strong> is also included to ensure optimum balancing of the optical tube.<\/p>\n<p>The STARQUEST-90MC comes with a complete set of accessories for immediate use. It includes a <strong>Red Dot researcher<\/strong> to facilitate the pointing of celestial objects, a <strong>90\u00b0 elbow return (1.25\u2033)<\/strong> for enhanced viewing comfort, as well as a <strong>universal smartphone adapter<\/strong>. The latter makes it easy to capture images of the Moon or planets directly with a phone, compatible with devices between <strong>54 and 90 mm<\/strong>.<\/p>\n<p>Versatile, high-performance and easy to use, the <strong>Sky-Watcher STARQUEST-90MC<\/strong> represents an ideal solution for discovering astronomy or for a compact, reliable instrument. Its unique combination of quality optics, flexible mounting and comprehensive accessories makes it an excellent choice for observing and capturing the wonders of the night sky.<\/p>\n<h3>Sky-Watcher STARQUEST-90MC technical specifications<\/h3>\n<table border=\"1\" cellspacing=\"0\" cellpadding=\"8\">\n<tbody>\n<tr>\n<th>Features<\/th>\n<th>Detail<\/th>\n<\/tr>\n<tr>\n<td>Telescope type<\/td>\n<td>Maksutov-Cassegrain<\/td>\n<\/tr>\n<tr>\n<td>Diameter<\/td>\n<td>90 mm<\/td>\n<\/tr>\n<tr>\n<td>Focal length<\/td>\n<td>1250 mm<\/td>\n<\/tr>\n<tr>\n<td>Focus report<\/td>\n<td>f\/13.88<\/td>\n<\/tr>\n<tr>\n<td>Magnifications supplied<\/td>\n<td>x62.5 &amp; x125<\/td>\n<\/tr>\n<tr>\n<td>Maximum magnification<\/td>\n<td>x180<\/td>\n<\/tr>\n<tr>\n<td>Optical treatment<\/td>\n<td>RAQ\u2122 (up to 94% reflectivity)<\/td>\n<\/tr>\n<tr>\n<td>Eyepieces included<\/td>\n<td>10 mm &amp; 20 mm<\/td>\n<\/tr>\n<tr>\n<td>Frame<\/td>\n<td>Equatorial \/ Azimuthal<\/td>\n<\/tr>\n<tr>\n<td>Gears<\/td>\n<td>122 teeth \/ 360\u00b0 on each axis<\/td>\n<\/tr>\n<tr>\n<td>Load capacity<\/td>\n<td>3 kg<\/td>\n<\/tr>\n<tr>\n<td>Tripod<\/td>\n<td>Adjustable aluminum with accessory tray<\/td>\n<\/tr>\n<tr>\n<td>Controls<\/td>\n<td>RA &amp; DEC slow-motion cables<\/td>\n<\/tr>\n<tr>\n<td>Accessories included<\/td>\n<td>Red Dot finder, 90\u00b0 angled return, smartphone adapter<\/td>\n<\/tr>\n<tr>\n<td>Smartphone compatibility<\/td>\n<td>Width 54 to 90 mm<\/td>\n<\/tr>\n<tr>\n<td>Brightness gain<\/td>\n<td>+26.5% compared to 80 mm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>&nbsp; Sky-Watcher STARQUEST-90MC : t\u00e9lescope Maksutov compact et monture polyvalente pour l\u2019observation astronomique Le Sky-Watcher STARQUEST-90MC s\u2019inscrit dans la gamme STARQUEST, une s\u00e9rie sp\u00e9cialement con\u00e7ue pour offrir une solution d\u2019observation astronomique \u00e0 la fois l\u00e9g\u00e8re, transportable et performante.
