Product Description

Celestron NexStar 130SLT 130mm Newtonian Reflector Computerized Telescope


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.

I'll start this review by saying I don't own this scope, however my neighbor purchased one as his very first scope to get into this hobby, and I've been helping him to learn it and the cosmos. I'm thoroughly impressed with this scope. I own two Schmidt Cassegrains: 8 inch on an IOptron ZEQ25 and 11 inch on an Advanced VX. ONE of my counter weights weighs almost as much as this entire setup. The reason I bring this up is because you can not beat the portability, ease of setup and take down, and simplicity of alignment on this scope. My neighbor can have his setup and aligned while I'm still carrying parts for mine from the car! It uses the same next star controller that's also on the higher end mounts so you have plenty of objects to choose from, or you can slew to your destination. The mount is extremely quiet when slewing. Maybe a little slower than others but that's ok. Once locked on target, the tracking is extremely accurate and it provides great views. If I had one real complaint, I would say it's the quality of eyepieces provided. It came with a 25MM and a 10MM. They provide OK views for larger things like the moon, but anything else isn't that great. Jupiter for example was just a white blob with four smaller white blobs. However, when putting in some of my eyepieces from the Celestron eyepiece kit, the scope came to life! If you're looking for a great beginner goto scope, this one is amazing for the price. Just get a couple of better eyepieces and this scope will really shine. (Posted on 5/24/2016)

The NexStar 130 SLT is a perfect beginner scope! The amazing efficiency of setting up, even in dark skies made stargazing much easier and quicker. Planets and the moon look outstanding through this telescope and even some brighter deep sky objects such as the Orion Nebula and the Hercules Cluster looked quite impressive. Highly recommend this scope for beginners! (Posted on 3/10/2014)
