With its large aperture and respectable focal length, the Celestron Omni XLT 120mm f/8.3 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. This model features the optical tube assembly with visual accessories, the manual CG-4 equatorial mount, and a sturdy stainless steel tripod to provide you with a complete observational platform right out of the box.
With its large aperture and a respectable focal length, the Celestron Omni XLT 120mm f/8.3 Refractor Optical Tube Assembly 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 magnification with the addition of optional eyepieces, and thanks to its large 2" focuser and reducer adapter 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. The OTA is offered without a tripod or pier for those who already have a reliable support system.
- Large 120mm aperture f/8.3 is ideal for lunar, planetary, and deep-sky viewing
- 1000mm focal length produces a high magnification potential
- Achromatic refractor lens configuration is reliable and does not require much maintenance or calibration by the user
- Proprietary StarBright XLT anti-reflection multicoatings reduce light loss while improving light transmission, color rendition, and contrast
- Resolution: 1.16 arcsec, Rayleigh; 0.97 arcsec, Dawes
- Sturdy 2" rack-and-pinion focuser maximizes light throughput while helping to produce a wide field of view
- Large 2" drawtube accepts 2" eyepieces and accessories, and helps to prevent vignetting when using wide-field eyepieces or imaging with large-sensor cameras
- OTA only, mount head and tripod required for proper use
- Vixen-style dovetail plate is compatible with any alt-az or equatorial mount with a Vixen-style saddle
- 12.5 pound weight, ensure the head and tripod you mount it on can carry this payload plus accessories used with it like imaging systems, eyepieces, diagonals, Barlows, and filter wheels
- 1.25" diameter barrel
- Accepts most 1.25" astronomical filters
- 25mm focal length produces 40x magnification
- 50° field of view
- 2-to-1.25" reducer allows the use of smaller 1.25" eyepieces and accessories in the 2" drawtube
- 1.25" snout and eyepiece holder
- 90° angle puts head in comfortable viewing position when scope is aimed straight, or nearly straight, up
- Star diagonal correct image horizontally, but not vertically, so images are right-side-up, but flipped backwards
- 6x magnification ensures a wide field of view for easier alignment and faster star-hopping navigation
- 30mm objective won't add excessive weight and bulk to scope
- Mounting bracket included
The Omni CG-4 Telescope Mount from Celestron is identical to the mount supplied with all Omni XLT series telescopes. This German equatorial mount offers RA and dec slow-motion controls and setting circles. The included adjustable tripod boasts 1.75" stainless-steel legs and a sturdy center brace/accessory tray. This mounting solution comes packaged with two counterweights to ensure proper balance and control.
