With its large primary mirror and moderate focal length, the Celestron Omni XLT 150mm f/5 EQ Reflector Telescope is an ideal choice for making detailed observations of the moon, with the capability to resolve distant objects like star clusters, galaxies, and nebulae. Its fast focal ratio further improves resolution while reducing exposure times during astrophotography sessions. It comes with the manual CG-4 equatorial mount outfitted with steel worm gears on both axes for smooth tracking and stability. Also included is a heavy-duty stainless steel tripod to provide a sturdy and steady platform.

What can you see through this 6” Celestron refractor?

With a relatively short 750mm focal length and a light grasp 459 times that of the sharpest dark-adapted eye, the scope is capable of producing surprisingly bright wide-field images of the faint fuzzies outside the solar system – nebulas, galaxies, open star clusters, and more.
But those objects requiring high power and high contrast – globular clusters, close binary star pairs, lunar and planetary images, etc. – are where this achromatic scope shines. Using optional eyepieces and/or a Barlow to boost the magnification, you can see subtle solar system details that are virtually invisible in smaller aperture scopes. You can study 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.
Chromatic aberration (a faint halo of spurious violet light around very bright objects, such as the planets) is present, as it is in all achromatic refractor telescopes, but is generally unobjectionable and is not a problem on the faint objects outside the solar system. Using the lens cap/aperture stop mentioned above will reduce its visibility. The use of an optional aberration-reducing minus violet filter will also help eliminate the spurious color (which many people find unobjectionable in any case).
Optically and mechanically refined, and very reasonable in cost for a big 6” aperture refractor, this Celestron Omni XLT150R has enough optical performance to keep you busy for the rest of your life.
