With a short 750mm focal length and a huge light grasp 459 times that of the sharpest dark-adapted eye, the scope produces bright and wide-field images of the thousands of faint fuzzies outside the solar system – nebulas, galaxies, open star clusters, and more. With its 6” aperture, compact deep space objects – globular clusters, close binary star pairs, etc. – are sharply resolved. Using optional eyepieces and/or a Barlow to boost the magnification, you can also see subtle solar system details that are virtually invisible in smaller aperture scopes. You can study complex lunar craters, rilles, mountain ranges, and low contrast lunar ray detail. With reasonable seeing conditions, detail in Jupiter’s cloud belts and the Great Red Spot (actually closer in color to the Faint Pink Spot at this point in time) are visible, as are dusky markings on the face of Saturn and Cassini’s division in Saturn’s brilliant rings. Because of its great light-gathering capacity, you may need an optional neutral density filter to cut down the brightness of some solar system objects for maximum resolution.
Optically and mechanically refined, and very reasonable in cost for a big 6” aperture reflector, this Celestron Omni XLT 150 has enough optical performance to keep you busy for the rest of your life.
