Includes CD-ROM "The Sky" Astronomy Software which provides education about the sky and printable sky maps we can try estimating it... The focal length is 650mm... which would about 25-26". The f.l. goes from the mirror to where it focuses, so a bit of that is in the focuser, but the tube extends past the diagonal some, too, so that's a wash. 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. Here are some key points to consider: View the details of the lunar surface, the rings of Saturn, polar ice caps on Mars, cloud belts on Jupiter or a number of the Messier objects such as the globular cluster in Hercules (M13), or Great Nebula in Orion (M42). Begin to explore some of the fainter Messier objects using the additional light-gathering capabilities of the 130 SLT’s 5” primary mirror.

Celestron NexStar 130SLT Computerised Reflector Telescope

Aluminum multi-coated glass parabolic mirror improves light transmission, color rendition, and contrast The Celestron NexStar 130SLT computerized telescope is a standard 130mm f/5 Newtonian like the Orion SpaceProbe 130ST, Zhumell Z130, and others. It uses a plastic 2” focuser, which is theoretically capable of handling 2” eyepieces. But it’s questionable how well the focuser can handle a heavy accessory if the secondary mirror is big enough for a wide-angle eyepiece to not vignette or, of course, if the too-small SLT mount can handle another kilogram of weight being added to it. There’s no question that the 127 SLT is more than satisfactory for many people, but if you’re looking for an all-encompassing view, the 130 SLT is the better option. PriceNeither telescope requires an immense amount of power to get up and running. However, you will have to keep AA batteries on hand to ensure you don’t encounter any downtime. SkyAlign Technology A: With the Celestron NexStar 130 SLT, you can see a wide variety of celestial objects, including the moon, planets, star clusters, nebulae, and galaxies. The telescope’s 25mm eyepiece provides a good balance of magnification and field of view. Q: How does the Celestron NexStar 130 SLT align? Firstly though, from an aside section the book, it tells us that the 60/80/114/4 (there was no 130cm OTA then) can be moved in azimuth by hand. I don't know if this is still applicable. Replacing the battery on the finderscope is very difficult, mainly because of the plastic cover. The end cap doesn’t fit very well and kept popping off. I had to resort to lining the inside rim of the cap with electrical tape. Also agree with mount issues. 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.

Celestron Nexstar 130 SLT Telescope - Rother Valley Optics Ltd

The Celestron Astro-Fi 130 is essentially identical to the NexStar 130SLT, but features Celestron’s Astro-Fi onboard WiFi system allowing you to control the scope with your phone or tablet, and sturdier tripod legs that significantly improve usability and stability compared to the flimsy NexStar SLT tripod. We don't have this item in our store right now, please allow for it to be transferred to our retail store. The problem is that when pressing the left and right * directional buttons on the hand control, the motor either doesn't move at all, or moves only very slightly and sporadic. It is also much louder than before. Then slew or move the telescope left, right, up, and down till the red dot appears over the bright object. When this happens, hit “Enter” on your keReflectors use mirrors to produce images and are cheaper to manufacture than lenses in refracting telescopes. Because of that, you will always get a much better performance for the money when you buy a reflecting telescope like this one.
