The Celestron NexStar 130SLT Newtonian Reflector Telescope offers a number of excellent features, including freedom from most optical aberrations, reasonable compactness & portability, and (most importantly) a ton of light gathering power per dollar spent.

The Newtonian telescope is the most popular configuration for more serious beginning or intermediate level astronomy enthusiasts. Deep-sky observation of galaxies, star clusters and nebulae, as well as lunar and planetary viewing are all possible with stunning resolution.

Celestron’s NexStar SLT refractors and reflectors have a sophisticated alignment system called SkyAlign™, which lets you use practically any three celestial objects to align the scope when these are included with the date, time and location. It is fast, accurate and easily performed by anyone.
