Celestron 127SLT overview

  • 1Description

Designed as an entry- to mid-level astronomical observation platform, the Celestron NexStar 127SLT 127mm f/12 Maksutov-Cassegrain GoTo Telescope gives users the ability to make detailed observations of the Moon, with the ability to easily see planets and reach outside the solar system to resolve distant objects like galaxies, nebulae, and binary or variable stars. The compact and powerful Maksutov-Cassegrain design corrects off-axis aberrations like comas and chromatic aberrations to produce images with true color rendition through the use of a front corrector plate with a convex meniscus lens, which not only eliminates the need for periodic collimation, but by the nature of the lens requires a smaller secondary mirror to limit obstruction and increase contrast.

The brain of the NexStar SLT is the venerable NexStar computer controller. Equipped with a database of over 4000 objects, including the planets, stars, nebulae, galaxies, and the complete Messier catalog, it can also be programmed with up to 99 custom user-defined objects and filters for custom object lists. Its intuitive menu-driven user interface provides the power to observe the heavens with nine slew speeds and three tracking rates, plus anti-backlash compensation. Features such as guided tours, extended information on 200 popular objects, and multiple alignment options make the NexStar controller easy to use and invaluable to new users and experienced stargazers alike.

    Celestron 127SLT reviews

    NexStar 127SLT 127mm f/12 Maksutov-Cassegrain GoTo Telescope is rated 4.4 out of 5 by 42.
    Rated 5 out of 5 by from Great Product and Value I use it occasionally, as I am an amatuer. I was considering the next level up Nexstar 6se, but just couldn't justify the price due to not knowing how much it would actually get used. I decided on this Nexstar 127SLT instead. At about 2/3 the price its performance is everything I hoped it would be. I've only gotten to use it a few times so far, but I've had a blast. I've gotten to see Saturn and its rings, the Andromeda galaxy (small smudge), and tomorrow I will use it to see the lunar eclipse and Jupiter. I never would have found the galaxy and star clusters without the computer built in. The setup was a breeze and operation is simple. Highly recommend!

    Rated 1 out of 5 by from Extremely disappointed Software failed within two days. There is supposedly a way to update the software but it required connecting the telescope to a Windows computer (no Mac support) via a serial port. YES! A serial port. BTW, you have to buy the cable, its not like they even include include it! It appears this is a well known problem too. Just google Celestron bootloader error and you will see for yourself. The optics seemed fine but this scope is dead in the water without its operating system. I contacted B&H who, as always, were a pleasure to deal with. They promptly authorized a return and I packed it back up and shipped it back. Fortunately I still had all the original packaging - it was only two days!

    Rated 4 out of 5 by from Nice grab and go scope This scope is perfect for my application. It's 5 aperature does the job for my observing sessions. With it I've had great views of Saturn, Jupiter, globular clusters and Andromeda. The GOTO works fairly well, its accuracy is dependent upon just how well you do an alignment. The scope is lightweight and easy to take along. That was my main concern. If you do not extend the tripod's legs all the way, the scope is fairly stable. I do not recommend extending the legs completely. This will result in lots of shaking and poor damping, especially noticed during focusing. Pricewise, I feel its an exceptional value.

    Rated 5 out of 5 by from Amazing quality and ease of use for so low a price I use this scope as a quick grab and go scope for rapid setup and easy portability, while not spending a lot of $. I have much larger, bulkier scopes that will show a lot more, but this one will surprise you with what it will show. Easy to learn and has accurate computerized pointing. I'd advise getting a hard plastic and storage container with lid, and maybe a pillow for padding, to carry the scope and mount/computer, and a separate tripod bag for the tripod. I'd also advise a Celestron Power Tank to supply 12v power away from an AC adapter. I've done exactly what I've just described myself. Very highly recommended. Insane quality for just over $ !

    Rated 4 out of 5 by from Great Scope for the Price Good crisp image, good focus behavior, fun to use. Batteries (eight AA) burn up fast; get the external power supply. Alignment is a bit time consuming. The hand-held controller takes some getting used to, and would benefit greatly from a redesign. No solar filter is currently made for the 127SLT. Once the scope is aligned you can choose an object from the menu and it goes there, at least close to it. I usually need to search around a little but not too much; it's allowed me to find objects I cannot find with my old fully manual 4 Newtonian, like M3 and M64 that have no close landmarks, and that alone makes this scope a worthwhile purchase, especially given the relatively low price.

    Rated 4 out of 5 by from Very good! It's my first telescope, and really liked it!'s Very powerful, I could see Saturn and Jupiter, which I had never seen antes.Das two lenses that come with it, the 25mm works best as a 09mm, despite the higher zoom, not is as clear as the 25mm.Pretendo buy additional kit lens Celestron, which will make my space exploration more interesting. Important to note that every time I turn on the telescope have to adjust my location and synchronize with some stars to make it work in automatic mode only realize it was hours and hours watching the sky after I finish using the telescope. It's very fun and interesting.

    Rated 4 out of 5 by from So Far, So Great I gave the 127SLT to my husband for a big birthday, nurturing our mutual interest in amateur astronomy. We needed something portable because we are New Yorkers on the go, working a lot in Uganda, where the night sky is impressive. I wanted something we could haul around easily but that still provides high quality viewing opportunities. It came extremely well recommended, including by Celestron technical staff, who heavily recommended this as the best amateur scope, advising among other things, that this model is a better deal (equally capable but cheaper) than the SkyProdigy and Nexstar 6SE models that I was also looking at. When I first told Robert at B&H what I wanted, he also raved that this is his favorite scope, plus consumer ratings show a model in the series as the top pick (and that's a reflector, while this is a Maksutov). Saving the money by going with the 127SLT allowed me to buy all the accessories we might need at this stage without breaking the bank and also keeping our first scope investment more modest. So far, our experience with it has been great. I was able to disassemble the mount from the tripod and pack it, along with the optical tube and some accessories with bubble wrap in a carry-on case and got it all the way to Uganda from NY unscathed! That's portable!, and the weight is very light, under 20 lbs, compared with the 30+ pounds of the other scopes I was interested in and that would have required two carry-on cases or an expensive suitcase, risky pack job and insurance to check into the airplane's hold. Assembling it was easy. We've taken it out every clear night over the past week and a half since my husband opened up his surprise gift. It's been a lot of fun to figure all this out and orient ourselves to the sky and to learn how to use a real telescope. It's amazing to have the motor and hand control that allows us to point and move the optical tube around with ease. We are also figuring out what all the different lenses do. The ones it comes with are good, and the 25mm is particularly important for finding things before getting more ambitious with stronger magnifications. The moon looks absolutely amazing. We also looked at Mars, but we couldn't see polar ice caps as others write that they have done fairly easily. It might be the time of year, but we are coming to understand what others write about - that this takes patience and practice, and it's not just about having the most powerful telescope. After having read others' reviews of instant gratification seeing details of Mars and Saturn on their first night out with the 127SLT, I have wondered if I should have gotten the 6SE for more money, dealing with the bigger portability challenges. But I re-researched it all and still feel very confident in the decision to go for the 127SLT, as, with lenses, it is just as powerful as the others and experiences less obstruction given how it's built. So, here are some of the challenges with it that we have to solve: 1) here in Uganda, we need to customize settings to use SkyAlign. We only tried that one night and failed, and we're pretty convinced it's because we are not putting in numbers correctly for our longitude, latitude and time zone, but we're aiming to get Celestron on Skype with us to talk us through it. 2) After we put some rechargeable batteries into the battery compartment (which are lasting a good long time), we had some trouble closing the compartment completely again. I'm sure we'll get the hang of this, but we actually tried pretty hard to do it without breaking anything, and it's still just slightly not fully clicked in. Will get some advice on that. 3) We don't consider 1 and 2 to be very pressing issues, as we assume they are easily solvable. The more substantive thing is 3) the tripod - it is decent, but when you use the motor, or you bump your eye against the eye piece, the image does wobble fairly easily. It settles quickly, but it's not like having a much heavier scope and tripod. We'll work on stabilizing this, but I think it's one of the factors in getting something so portable. I think it's true that the ease of use of this telescope, along with its high quality optics, make it much more likely that we'll actually use and enjoy it than if we got something much heavier and less portable. As for the database, we haven't used it yet, but in general, 4,000 objects is plenty to keep us busy for a good long time, while we learn what we are doing. If Celestron upped this to 10,000 or 40,000 like some other models, it would also be great, but we are also just into finding things ourselves, so, this is not a big issue for us. Overall, so far, I could really give this product a 5, but because of these minor things and because they don't offer a 4.5 rating, I chose 4. It's really great, and we will get better and better at what we're doing with it over time - it's perfect for our needs, and like so many others have said/written elsewhere, we can easily see why people say this is a scope that they will keep for a lifetime even if they invest in fancier, bigger things over time.

    Rated 5 out of 5 by from Great Telescope I had owned department store telescopes my whole life and was ready to step up to the next level. I researched and found that the 127SCT was exactly in my price range. I finally made the decision to order it. Ordering from B&H was fast, easy and painless. The telescope arrived exactly on time. As most people stated, I had problems configuring the Go To on the first night, but after I got the spotter scope aligned properly, it was a breeze. I have had several great nights of viewing the planets, Saturn is absolutely amazing. I would recommend purchasing the lens/filter kit and external power cord.
