• Newtonian reflector optics: 6” (150mm) aperture, 750mm focal length, f/5 Newtonian parabolic mirror reflector using aspheric shaping technology for images that have virtually no spherical aberration and are free from the chromatic aberration of achromatic refractors. The optical tube is aluminum, to allow the mirrors to cool to ambient temperature more quickly. Also, the lower end of the tube is sealed to reduce image-degrading thermal currents within the optical tube. These features extend your undisturbed viewing time by minimizing the time you have to wait for the images to stabilize after you take your scope outside in the cold air of late fall or winter. The scope’s tube end rings are sturdy die cast aluminum, to protect the tube during transport and provide exceptionally rigid support for the optics. The mirror cell’s six-screw push/pull locking collimation system keeps the primary mirror aligned far longer than conventional mirror cells – so you spend more time observing, and less time adjusting the optics. The lightweight optical tube rotates in its felt-lined die cast cradle rings to bring the focuser and finder to the most comfortable viewing position. The mounting rings even include a built-in piggyback mount for wide field astrophotography (using an optional motor drive). The 27” long aluminum optical tube weighs only 12 lbs., making it easy to transport and assemble in the field.

• Starbright XLT multicoated mirrors: Fully coated with multiple vacuum-deposited layers of high reflectivity aluminum. The aluminum coatings are enhanced with titanium dioxide for maximum reflectivity and overcoated with a protective layer of silicon monoxide (quartz) for long life. They are the same mirror coatings used on Celestron’s largest and most expensive optical systems.
