Sky-Watcher STARTRAVEL telescopes are two-element, air-spaced achromatic refractors, that are well proven performers for ‘Rich-Field’ views of comets, star fields, star clusters, nebulae, bright galaxies & planets, the Moon and the Sun (with proper safety filtering!), as well as giving excellent daytime terrestrial views. These wide-field, short-tube telescopes are great as fixed aperture lenses for both Astrophotography and terrestrial photography. Their “fast" focal ratios make them useful for capturing lunar and solar eclipses as well as nature photographs. The intuitive and easy to use AZ3 Alt-Azimuth mount provides excellent stability and precise control, via its slow motion cables, on both the horizontal (azimuth) and vertical (altitude) axes. Magnifications (with eyepieces supplied): x20 & x50 Highest Practical Power (Potential): x204 Objective Lens Diameter: 102mm Telescope Focal Length: 500mm (f/4.9) Eyepieces Supplied (1.25"): 10mm & 25mm Direct SLR Camera Connection Red Dot Finder Dual-Fit 1.25"/2" Focuser 45º Erect Image Diagonal 1.25" Multi-Coated Objective Lens AZ3 Deluxe Alt-Azimuth Mount Aluminium Tripod with Accessory Tray 62.5% more Light Gathering than 80mm AIR-SPACED TWO-ELEMENT ACHROMATIC REFRACTORS An ordinary single lens brings different wavelengths of light to different focal pointsAll Sky-Watcher Refractors are built with air-spaced two-element lenses, which reduce chromatic aberration more than standard doublet lenses.
