With its large aperture and respectable focal length, the Celestron Omni XLT 102mm f/9.8 EQ Refractor Telescope is an ideal choice for making detailed observations of the Moon and planets, with the capability to resolve distant objects like star clusters, galaxies, and nebulae. Its moderate focal ratio gives it the ability to achieve high magnifications with the addition of optional eyepieces, and thanks to its large 2" focuser the available options are nearly limitless. The larger drawtube also helps to prevent vignetting when using wide-field eyepieces during observation sessions, or when using large imaging-sensor cameras for astrophotography. To allow the use of the included 1.25" eyepiece and diagonal, a reducer adapter is included and installs easily without tools. The scope comes with the manual CG-4 equatorial mount outfitted with steel worm gears on both axes for smooth tracking and stability with two counterweights for proper balancing to ensure smooth movement. Also included is a heavy-duty stainless steel tripod to provide a sturdy and steady platform.
