Questions & Answers

Shopper : when shipping restriction ends?ANDREW R : Responses on this Q&A system are from other customers, NOT Adorama employees (unless indicated by email or otherwise as "staff"). For best response regarding specific purchase inquiries please call 800-223-2500.
Shopper : What's the best solar filter for this scope?DEBORAH H : I use an astrozap baader solar filter 136mm-146mm with my 127SLT. I would not get a glass filter.
Shopper : can this telescope be used on a table top?THOMAS R : The tripod is a little bit too tall for table top use. But far more important, a table top is nowhere near sturdy enough to use for this (or any) telescope. Due to the magnification involved, even the slightest vibration will cause the image to jump all over the place! You need to have the tripod placed firmly on solid ground for best viewing. Even if you have the tripod set up on a deck, the image will jump around just from someone gingerly walking across the deck! This applies to all telescopes, not just this one.PETER M : With the tripod legs completely retracted, it, conceivably, could be used on a low table top. Alternately, a shorter tripod could be used. Not really designed for tabletop use. Check out some of the Meade telescopes in similar focal lengths. They have GOTO capabilities and are designed for tabletop use but also can be mounted on a suitable tripod.PHILLIP L : I dont see why not. as long as the table top is big and flat enough.ROBERT T : No, the base of the SLT mount will not sit by itself on a table top.ANDREW R : Unfortunately no, not really. This telescope will likely be far too large and heavy for tabletop use.

Amazing telescope!

As a starter telescope, it is way better than what I expected to arrive. My only "issue" would be that the telescope does not rotate as quickly as I'd like even at max speed but aside from that it works great! Definitely worth the buy

Celestron

Ordered my telescope which was on back order but I got it sooner than I thought I would. Set up was easy and I love searching the stars.

Great Little Scope

I recommend the scope for lunar and planetary photography. For those who are comfortable taking longer exposures, it is acceptable for deep space as well.

Alignment

This scope requires 3 stars to align for the computer to work. The telescope must be level. I have had this scope about 3 yrs now and I still have not been able to balance this scope. Other then what I have said, The optics are good for a beginner.

Great Beginner Telescope

This is my first telescope and I am very pleased with it. The clarity is amazing and when dialed in correctly will follow an object through the sky the entire night. Of course I'm usually bouncing around and checking out several sights so I don't zero in on just one thing for long periods of time. But you can return to an object with ease which I have done many times. Honestly, this telescope has not disappointed at all; it's easy to transport, easy to set up and easy to use. Hope you enjoy!

Good beginning telescope

Purchased additional camera mount but too much wobble when pressing shutter button. Able to view Saturn and rings with 15MM lens. Starfinder lens takes getting used to but must be aligned properly to work correctly. Good beginner scope!

Great But sightscope seems poorly made

I use the scope to watch the space station and the moon. This is my first telescope, and other than the sightscope giving me a feeling it has a short, its wonderful. I will add The software provided seems old and feel the instruction book could use a major overhaul. It would be nice if the cord to update the Nextar firmware was provided instead of being an antiquated extra part. This is my first telescope EVER and well, it doesn't just come out of the box ready to go. Overall, a good buy, BUT again more information should be included.

What a great buy

This is a fantastic deal for a refractor telescope. This is my 6th telescope. I have newts and schmits.My best schmit is a c8in and nwt is a 12in. This is my first refractor. I always wanted one but cost for aperture was was too expensive.The slt 102 seemed worth a try. I am so happy I did. I wanted a good grab and go and this is it. I already had a good 2in diagonal and put that in it right away. So i'm not gonna trash the 1.25 that comes with scope.I read bad comments about the star finder scope and have to say maybe these people got a different finder scope. I love mine. Works great! For twice the money you can't do better!

GoTo is not perfect but gets me close. Wish I could afford a bigger telescope but I think this is a good choice for the price.

Perfect telescope for anyone

This is a fantastic telescope for a beginner or experienced astronomer. By upgrading the eyepieces and diagonal you'll get a high quality observing instrument. Beginners will have a small learning curve but once you understand the controls you'll be able to tour the universe. I have many telescopes from Celestron and they're are all large 11". This 102mm is highly portable and is a joy to use. I rate is 5 stars!

Spend a bit more and get something else

SLT handpiece light flickers on and off after a while, making a torch neccessary for using it. View is very limited with supllied eyepieces. Unstable. Hard to focus due to instability. Basically, the SLT doesn't work, we can never find 3 bright stars that it recognises. It is a kids toy product, buy something else!

OMG! I can see Jupiters moons!

I found the scope simple to setup and simple to align and stayed in alignment pretty well. The optics seem to be of good quality for the price and the goto feature is just wonderful. The focus knob is too close to the main eyepiece causing a more unstable image as my finger bumps into into the diagonal after a 1/4 turn. A glow in the dark bubble mount would have been a nice touch as well.

Just imagine the universe at your fingertips with the NexStar 127 SLT 127mm Maksutov-Cassegrain Telescope. This advanced, computerized GoTo telescope is the perfect blend of affordability and sophistication, making it an ideal choice for both entry-level and mid-level astronomy enthusiasts.

The NexStar SLT series, which includes refractors, reflectors, and Maksutov-Cassegrain models, offers a range of popular sizes, each packed with innovative design features. The preassembled, adjustable stainless steel tripods, coupled with quick-release fork arms and tubes, allow for a hassle-free setup in mere minutes, without the need for any tools.

With the NexStar 127 SLT, you can explore the intricate details of the lunar surface, witness the phases of Venus, observe the polar caps on Mars, marvel at Jupiter and its four moons, and even see Saturn with its rings in clear view. Beyond celestial viewing, most NexStar SLT models can also serve as land-based spotting telescopes.

Powered by 8 AA batteries (user-supplied) or an optional AC adapter, this portable telescope is designed for travel. The internal battery compartment powers the high-precision servo motors, ensuring rigid, low-vibration performance while eliminating cord wrap issues associated with external battery packs.

The NexStar's ergonomically designed hand control enhances user experience. You can either remove the hand control for remote use or leave it cradled for hands-free operation. With a simple button press, you can access the object catalog, adjust the slew speed, learn fascinating facts about celestial objects, or check the visibility of a desired object in the sky.

Celestron's revolutionary SkyAlign technology (patent pending) simplifies the alignment process. Just input the date, time, and location into the hand control, then slew the telescope to any three bright celestial objects in the sky. There's no need to know the names of the stars; you can even choose the Moon or bright planets.

Experience the cosmos like never before with the NexStar 127 SLT 127mm Maksutov-Cassegrain Telescope, your gateway to the stars.
