CELESTRON  • NexStar 130SLT 130mm Computerized Newtonian  •   31145  

With 30% more light gathering than the 114mm telescope and 345x more than the human eye, the Celestron NexStar 130SLT Newtonian Reflector has the shortest focal length of the entire NexStar SLT series, meaning that it is suited for planetary observing as well as many bright deep sky objects such as bright galaxies, nebulae, open cluster, and globular clusters due to its 5" primary mirror.

For astronomers taking their first stargazing night in a non light polluted location, it can be tough to align the scope. However, Celestron has implemented a few different alignment options, but the one that probably comes most in handy for the beginner is the sky align method. No knowledge of the night sky is required. All the user must enter into the NexStar hand controller is the location, time and date. Then they must slew and center the telescope to three bright stars (or planets) and the software can calculate the axis and coordinates between each selection and determine what stars were selected. Basically, the telescope aligns itself! Once properly aligned, the observer has a 4,000 object database to slew through! These include Messier objects, NGC, IC as well as the planets. The observer can also control their telescope with a computer using the optional RS-232 cable. The NexStar contoller software can be updated via flash whenever software updates become available.
