What customers say about "Key Specs"
Celestron NexStar 5 SE Telescope
  • This scope is perfect for a beginner, can be set-up in about 10 minutes, and aligns easily by pointing to three bright objects in the sky.
  • Great Telescope for 3 years now. I bought the 5" for the polar alignment feature. There are many good reviews on here about the scope already. So
  • Portable, not very heavy, and easy to set up
  • Great telescope. I got it as my second telescope after buying a dobsonian 6inch. I wanted something that was easier to store and put away when I'm not using it.
  • Great detail on the objects you are viewing. I get great views of the moon, Jupiter(And its moons), Saturn, nebula, and other objects. Its really amazing.
Celestron NexStar 127SLT Mak Computerized Telescope (Black)
  • My wife bought this scope for me for Christmas. I had no experience with astronomy prior to that. It's a little finicky to set up but once you do it correctly, it'll work well.
  • Eventually I settled on the 127SLT Maksutov-Cassegrain. It was small enough that I could transport it to and from the local astronomy club, which is a big plug for a beginner.
  • The 127 millimeter diameter aperature equates to about 5 inches in size. While this is considered small in today's era of large Dobsonian monsters, the telescope system fits in my car, and is light enough that I can take it outside easily.
  • If you want a scope for Nebulas and to take pictures of them, don't get this scope. The aperature is 5 inches with a long focal range; however think about this
  • Great 'scope. Easy to set up and use. My first time out, I was up an observing in 5 minutes. Super Celestron Optics.

What customers say about "Features"
Celestron NexStar 5 SE Telescope
  • Good quality material. Everything looks and feels great.
  • Easy to use the basic features on it.
  • Great Telescope for 3 years now. I bought the 5" for the polar alignment feature.
  • Nice telescope--grab and go is a nice feature. Plenty of good things to like about this scope.
  • The original viewfinder sucks, has to go...fast. Try to get a "Telrad Finder Sight", that thing is awesome, easy use and easy to mount.
Celestron NexStar 127SLT Mak Computerized Telescope (Black)
  • The other great feature is the fully computerized "Goto" capability of this telescope.
  • As you probably know, this is a computerized goto scope. That means that it is motorized, and there is a hand controller with a readout where you can tell the scope what you want to see by pressing some buttons.
  • I like the tracking and goto feature. It's really easy to 3 star sky align.
  • Overall a fantastic product for budding astronomers with high quality, excellent features, and useful accessories.
  • Easy to assemble. Easy to use. I like the features, especially the auto-tracking. I'd recommend this telescope to everyone who is interested in astronomy.

What customers say about "Mount Information"
Celestron NexStar 5 SE Telescope
  • The single arm mount seems very solid though the spur gears are not optimal for fine tracking needed for loooong exposure astrophotography.
  • Even though it's an Alt-Azimuth mount (not an equatorial) it tracks objects pretty well.
  • First thing I did was level the mount and align the finderscope.
  • Mount is solid, slight bounce on high power but settles near immediate, is what you want!
  • The second cheap item is the spot level provided. It has a peel off sticky tape on the back to mount the level.

  • The tripod mount is good, but will wiggle a bit in the breeze, especially at higher magnifications
  • The reflector however is a bit long for this mount but very usable. Just know you won't be pointed st the Zenith before it hits.
  • The slt mount is great for me because i don't know the sky. It will help me learn the sky because i still need a star map or i would still be wondering aimlessly.
  • The hand held motorized mount works great.
  • Alt az mount is limited to like 70 degrees up so no looking near the zenith of the sky.
