Celestron NexStar 127SLT Computerized Telescope

Celestron NexStar 127SLT Maksutov-Cassegrain Telescope on GoTo Mount is designed with an aperture of 127 mm, a focal length of 1500 mm and a focal ratio of f/12. See the details of the lunar surface, Venus and its phases, Mars resolved as an orange disc, Jupiter and its four Galilean moons, Saturn with its rings plainly visible and much more! Designed to be an affordable entry-level to mid-level computerized GoTo telescope, its pre-assembled, adjustable stainless steel tripods, and quick release fork arms and tubes, NexStar SLT telescopes can be set up in a matter of minutes -- with no tools required!

Celestron NexStar 127SLT Maksutov-Cassegrain Telescope Features

  • Designed on a fully computerized altazimuth mount.
  • StarPointer finderscope to help with alignment and accurately locating objects.
  • Sturdy stainless steel tripod and accessory tray for a quick, no-tool setup.
  • NexStar computer control technology with a database of over 4,000 celestial objects.
  • Upgradeable software for motor control units and hand control by downloading product updates on the Internet.
  • Internal battery compartment to prevent cord wrap during use.
  • Auxiliary port for additional accessories (such as a GPS accessory).
  • Includes NSOL software for basic control of your telescope via computer (with optional RS-232 cable).

 

These Celestron NexStar GoTo mounts are powered by eight AA user-supplied batteries, or an optional AC adapter (#CE-18773), making them perfect for travel. The internal battery compartment provides power to the high precision servo motors for fixed, low-vibration performance while eliminating cord wrap issues associated with external battery packs. Remove the hand control from its holder for remote use or leave it cradled for hands-free operation! With a touch of a button, you can select the object catalog, change the slew speed (nine speeds), view fascinating information about an object, or simply know if the desired object is visible in the sky.

With Celestron's SkyAlign Technology, aligning your telescope is easier and faster than ever. Simply input the date, time and location (the CPC models have built-in GPS that does this for you) and then align the telescope to three bright stars of your choosing. You do not need to know the names of the stars, you can even pick the moon or bright planets! The NexStar computer system will automatically figure out which stars were chosen and then align the telescope. 

Included Technology

Nexremote

This telescope control software replaces the hand control and allows the user to remotely control their Celestron computerized telescope from their personal PC or laptop.

SkyAlign

SkyAlign alignment technology makes setting up a computerized telescope simple, fast, and accurate. Just point the telescope at any three bright objects — stars, bright planets, or even the Moon — and your telescope can orient itself with the night sky.

Compatible Technology

LiFePO4

The new Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries, great for those Astronomers on the go.

Starsense Technology

Celestron’s patented StarSense Technology makes it easier than ever to locate objects in the night sky, even if you’ve never used a telescope before. Turn it on and push ‘Align.’ In about three minutes, you’re ready to observe!

WiFi

WiFi technology encircles the globe in a web of connectivity, knowledge, and information. Now, Celestron is using that same technology to allow stargazers to connect to the night sky and enhance their experience of the cosmos in fun and unique ways.

Regarding this 'computerized' telescope...Not so much.

And while I was just looking for a little bit more power than my prior mostly 80% manual telescope, this one seemed like a good idea but it was not. For me it was not a good idea as I just wanted to get into the computerized navigation telescope market but alas it is way too old and is power **** and as a warning, this model series was brand new in 2003. Also aside from the huge power source issues, datenesses and the spotty at best 'wifi' alternative adapter, it is really not a great system that actually works for anyone who wants a smooth operating system and navigation system. Avoid it.

Fantastic portable GOTO telescope!

This was my first telescope. I also bought the DC power cable because I don't recommend using just the AA batteries. It works, but it looks like it is struggling. With an external battery, I have no problem at all. The mount is maxed out with the weight of the telescope and wind can really knock it around. That being said, I love this telescope. I can carry it with one hand with the battery and cable in my other and a couple eyepieces in my pocket. Alignment is super easy and quick. The slew speed is slower than my CGEM, but I wouldn't expect them to be comparable. The tube itself is great. I can see the Cassini Division in Saturn and the bands of Jupiter. On clear, still nights, I can see the red spot on Jupiter. I was a bit underwhelmed with my 8" SCT because the planets looked basically the same through either telescope. Jupiter is just blindingly bright through the 8". Finally, the accuracy of the GOTO after aligning on just 2 stars is incredible. I can use the 9mm eyepiece, select Saturn and it will slew almost exact. I am probably to blame for the error because I align with the 25mm eyepiece to speed up the process. In all, for the ease and speed at which I can set up the 127 SLT and have very accurate GOTO, this telescope is a fantastic buy. My only warning is to NOT put more weight on the tube. ie. Heavy Camera or Guide Scope.

Overall performance

It's great so far.Saw Vega in Lyra.Leo 3 Viewed Juipter it was awesome.Saw both bands A close up of Moon However I hate The red dot finder. Instead I used my old 6x30 Finderscope from My old Celestron C102 HD Refractor. It fits perfectly in the same bracket. Listen Celestron my old 6 x 30 Finderscope is far more accurate.Way easier to align. You should be selling all Nextstar telescopes with these. Do you make a 6x30 with a right angle Finderscope.If so how much?
