Celestron 127SLT
Overview
Designed as an entry- to mid-level astronomical observation platform, the
Celestron NexStar 127SLT 127mm f/12 Maksutov-Cassegrain GoTo Telescope
gives users the ability to make detailed observations of the Moon, with the ability to easily see planets and reach outside the solar system to resolve distant objects like galaxies, nebulae, and binary or variable stars.
The compact and powerful Maksutov-Cassegrain design corrects off-axis aberrations like comas and chromatic aberrations to produce images with true color rendition through the use of a front corrector plate with a convex meniscus lens, which not only eliminates the need for periodic collimation, but by the nature of the lens requires a smaller secondary mirror to limit obstruction and increase contrast.
The brain of the NexStar SLT is the venerable NexStar computer controller. Equipped with a database of over 4000 objects, including the planets, stars, nebulae, galaxies, and the complete Messier catalog, it can also be programmed with up to 99 custom user-defined objects and filters for custom object lists. Its intuitive menu-driven user interface provides the power to observe the heavens with nine slew speeds and three tracking rates, plus anti-backlash compensation. Features such as guided tours, extended information on 200 popular objects, and multiple alignment options make the NexStar controller easy to use and invaluable to new users and experienced stargazers alike.
Optical Tube
127mm aperture
f/12 focal ratio
1500mm focal length
Maksutov-Cassegrain optical design
Front convex meniscus lens corrects spherical and chromatic aberrations and comas (off-axis aberration) across the entire field of view
Compared to Schmidt-Cassegrain telescopes, a smaller secondary mirror reduces obstructions and increases contrast
Fully coated optics improve light transmission, color rendition, and contrast
Resolution: 1.1 arcsec (Rayleigh); 0.91 (Dawes)
Internal focusing system
Vixen-style dovetail plate
NexStar Controller
4000+ object database
99 customizable user-defined objects
Expanded information on over 200 most popular objects including history, facts, and mythology
Tracking rates: Sidereal, Solar, Lunar
Nine slew speeds: 2x, 4x, 8x, 16x, 32x, 64x, 1°/sec, 2°/sec, 3°/sec
Anti-backlash compensation trains out the intrinsic play between gears to improve GoTo and tracking accuracy
Alignment procedures: SkyAlign, Auto 2-star, 1-star, 2-star, solar system
SkyAlign allows fast and easy alignment without having to polar align or even know the names of stars
Tour mode: Seeks out the best objects and automatically slews to them
Constellation Tour: Tour of the best objects within a specific constellation
Identify mode: Searches the database catalogs or lists and displays the name and offset distances to the nearest matching object
Flash upgradable via Internet
2-line/16-character LCD display with 19 backlit LED buttons
RS-232 communication port for updating or computer control
