130 mm reflector with computerized mount

The Celestron NexStar 130 SLT is a 130 mm Newtonian reflector on a fully motorized altazimuth mount. It provides 30 percent more light gathering than the 114 mm model. The system suits beginners and experienced observers who want push-button targeting of deep-sky objects.

4000-object database and StarPointer finderscope

A computerized hand controller stores over 4000 celestial targets including 600 galaxies and 300 clusters. SkyAlign technology and the red-dot StarPointer finderscope simplify alignment so the telescope can automatically slew to any catalogued object within minutes of setup.

650 mm focal length at f/5 with 1.25" eyepieces

The 650 mm focal length and fast f/5 ratio deliver wide, bright views of nebulae and star clusters. Standard 1.25 inch eyepieces are supported; the optical tube does not accept 2 inch barrels. An auxiliary port allows optional GPS or other accessories for expanded capability.

Questions about this item

How often will the 130 mm reflector mirrors need collimation?

The 130 mm Newtonian reflector uses a standard mirror cell with three collimation screws; check alignment after transport or once per observing season and adjust with the built-in screws if stars show coma.

What limits a full-night session on the motorized Altazimuth mount?

The mount runs on eight AA cells or an external 12 V supply; battery voltage drop after several hours of continuous slewing is the first practical limit, so a regulated 12 V pack is recommended for all-night use.

How much noise and heat does the mount produce during extended tracking?

The motorized fork arm uses low-torque stepper motors that emit a faint whir only during goto slews; while tracking, the drive is nearly silent and generates negligible heat, so ambient temperature stays unchanged.
