Celestron 31145 NexStar 130SLT Portable Computerised Newtonian Reflector Telescope, Grey

Product Information

You can’t go wrong considering the price point, as many other telescopes on the market can easily be much more expensive.

The focal length of this telescope is 650mm. Focal length is the distance from the primary mirror to the focal point in the focuser. The focal length and aperture size translates to a fast F/5 (divide 650 by 130) telescope. This telescope isn’t for targets on Earth. It’s Newtonian design demands that you stand or sit at the side of the optical tube. And the image is inverted. So it’s not a point and shoot spyglass. [For that, you would want a Refractoror Hybrid.] But take the NexStar 130 out on star-date night and your view will be truly stellar. In my opinion, the small finder scopes with the crosshair are better because they are actually small scopes that are more accurate. But the red dot finder will do the job, and you can always upgrade it later to a proper finderscope. If you feel that 60x up to 167x magnification is more than enough, then the 127 SLT is a great choice.Just a final point. I viewed the first quarter Moon last Thursday and compared the 130 SLT with my Celestron 9.25. The seeing was excellent. There was nothing that I could see with the Celestron that I couldn't with the SLT, but there is a difference that I have previously noted comparing large scopes with small ones. With the big scope things - such as the Hygenus Rill - make themselves apparent. With a small scope you need to "look" a bit harder. To truly appreciate the performance and image quality of the Celestron NexStar 130 SLT telescope, you’ll need to spend some time familiarizing yourself with its features and making adjustments as needed.

Otherwise, the batteries are enough for an outdoor session and last long. If you want to be safer, bring some spare ones with you.

Focal Ratio: The telescope has a focal ratio of f/5, which means it is capable of capturing a relatively wide field of view. This is ideal for observing large celestial objects like nebulae and the Orion constellation. Reflectors use concaved mirrors to collect light with the mirror diameter referring to its aperture. As large mirrors are relatively inexpensive to manufacture, reflector telescopes tend to be cheaper than similarly sized Refractor or Catadioptric telescopes giving excellent value for money. Specifications: The Sky-Watcher Virtuoso GTi 130P features the same optics as the 130SLT but in a collapsible tube with a dual manual/GoTo tabletop Dobsonian mount which is controlled with an app on your smartphone or tablet. The Virtuoso GTi 130P is available in a manual format, the Heritage 130P, as with the 150P from Sky-Watcher. We did notice the images wiggle a bit for a second or so after the optical tube was nudged, a consequence of that relatively light duty mount and tripod. But telescope makers must trade-off something, somewhere, to stay in business.
