With its large aperture and fast focal ratio, the Celestron Omni XLT 150mm f/5 Reflector Optical Tube Assembly is an ideal choice for making detailed observations and capturing excellent astroimages of the moon and planets, with the capability to resolve distant objects like star clusters, galaxies, and nebulae. Its sturdy focuser accepts standard-sized 1.25" diameter eyepieces, opening up a wide array of magnification choices from the near-limitless available options on the market. The OTA is offered without a tripod or pier for those who already have a reliable support system.
Optical Tube
- Large 150mm aperture is ideal for lunar, planetary, and deep-sky viewing
- Fast f/5 focal ratio requires shorter exposure times to capture the same images as slower scopes, while producing brighter and wider observational views
- 750mm focal length produces a moderate magnification potential and fast focal ratio
- Newtonian reflector design produces a shorter and lighter tube, versus a similar refractor, for easier handling
- Proprietary StarBright XLT anti-reflection multicoatings reduce light loss while improving light transmission, color rendition, and contrast
- Resolution: 0.92 arcsec, Rayleigh; 0.76 arcsec, Dawes
- Sturdy rack-and-pinion focuser can handle larger eyepieces and accessories without flexing
Mounting
- OTA only, mount head and tripod required for proper use
- Mounting ring assembly allows the user to rotate the optical tube and orientate the eyepiece to the most comfortable position for any user
- Vixen-style dovetail plate is compatible with any alt-az or equatorial mount with a Vixen-style saddle
- 12-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
