Celestron - NexStar 127SLT Computerized Telescope - Compact and Portable - Maksutov-Cassegrain Optical Design - SkyAlign Technology - Computerized Hand Control - 127mm Aperture

To begin, the photos are shaky and blurry because I shot them by trying to stick my phone close to the eyepiece, they do not do this scope justice, it is fantastic! I had very limited experience with telescopes, but the 127 SLT has blown away my expectations. I have seen the Orion's Nebula, rings of Saturn, bands of Jupiter and the 4 Galilean moons clearly. Various star clusters and a couple galaxies. Once you understand the setup and the must have upgrades you'll be ready to go. Pros: The scope is easy to assemble. The red dot is perfectly fine for what it is and gets you close enough. The 5" lens is more than enough to see the usual objects (moon, Saturn, Jupiter, and other Solar System Bodies). The first time i found the Andromeda Galaxy i was a bit disappointed as it just looked like a yellowish smudge in the sky, cool nonetheless. Then I observed Orion's Nebula and couldn't believe how good this little scope does, granted the tripod leaves much to be desired (but there are cheap work arounds, I'll explain in the cons. It's portable if you buy the right case which is great to get out of the city light pollution or to take camping. The tracking and auto alignments are great. Always perform the 2 star alignment as the 3 star align fails 9 out of 10 times, but 2 star is very good. Once 2 star is aligned you can activate tracking and the scope keeps the object you're viewing within frame or very close over a period of time, and you can let the computer drive you to your next object. It's super useful on cold nights and to not have to constantly correct where you're looking. Cons: the mount/tripod is not great, but I've mitigated vibrations and instability by buying cheap anti vibration pads on Amazon $20 and by loading a sandbag with 10lb weight and placing it on the plate of the tripod and this makes it 100 times better. This will be something I upgrade eventually for my own purpose, but I have no problems now and have no need to upgrade after the pads and sandbag trick. The standard pieces you'll want to replace and buy better one's, these pieces are always cheap that come with the scope, but I still use the 32mm for initially locating the object I'm looking for. You'll want something around a 25-32mm, 15mm, and a 9mm , and a 2x Barlow, this is all you need and you will be able to push your scope to its limits and on good nights with low atmospheric interference push a little past them. Further, i cannot say much on battery longevity in the scope as I immediately bought a cheap $8 adapter and used an extension cord for power until I bought the celestron mobile power supply for when I take it on the go. Overall, i wouldn't have changed my mind, this purchase was perfect, the tube didn't need alignment, the motors haven't messed up on me and i have nothing negative to say about this purchase. Recommended: buy the power supply, it's a game changer. Also, get the anti vibration pads and some way to weigh the tripod down, this makes a world of difference. Upgrade your eye pieces, you don't need anything crazy expensive, and buy a case to store your tube, tripod, and accessories, it makes storage and moving it a breeze. There are other well written reviews, so take your time and review what you need before buying. As my first telescope as an adult I'd rate this 9/10 for price and the ease of use and accessories built into the computer of the mount. Next scope will be a 10" lens with a solid equatorial mount base as i have no place for a Dobsonian in my current living situation. Good luck and clear skies!

In my opinion, this is an excellent beginner/intermediate or advanced grab and go scope providing crisp images, ease of use and many desirable software capabilities. I recommend it. My training is in the physical sciences but not specializing in Astronomy or Astrophysics. I have always had interest in the stars from childhood and from having been a navigator in a destroyer during my naval service where I used them to navigate by. Several years ago when I retired I purchased two 1960s vintage equatorial mount 60mm refractors at garage sales and I have been using them while I did some research and reading to decide on the best next telescope to purchase. I decided on a Maksutov-Cassegrain due its reputation for crisp, clear images and on Celestron NexStar for its quality reputation and the features of its GoTo/tracking software program. The deciding factor was that it was on sale at a large discount. I did consider Meade and Orion scopes before deciding on this particular Mak. This year (2013) I took some of my tax refund dollars and purchased the Celestron NexStar 127 SLT Mak and also purchased some of what I consider to be essential accessories. The purchase price of the tube and mount are only part of the price for a complete capable system. Beyond the sock items provided in the initial package, you will need lenses, filters, adapters, etc to fully exploit the capabilities of the mount, software and optics. In other words, to see the most, coolest stuff. By the time I have purchased all of the essential accessories to do this, they will cost almost as much as the telescope itself. I have used the telescope every clear night for the last several weeks and I am very pleased. The NexStar program and alignment are easy to use and provide a better that ballpark result when going to an object. I did purchase the GPS unit, the Celestron accessory kit with additional lenses and filters, the house current and car battery power adapter chords, the USB interface cord, and the light pollution and oxygen filters. I live in the Phoenix suburb of Glendale so light pollution is a factor. The filters help. So far everything works beautifully. My only two complaints are not vital but more nuisance -that the GPS can take some time to synch -- be patient, I was not and had some self inflicted difficulties the first time I used the Mak. -the tripod can be a little wobbly. I will eventually get a heavier tripod, the GPS is what it is. I will try adding some five or ten pound weights to the tripod to see if that stabilizes it sufficiently. I am not done with accessories. Next on my list is a hard case for the tube and a canvass bag for the tripod and accessories so I can safely carry the system to the dark sky sites and star parties. I do want to try some web cam photography of solar system objects so a webcam purchase is in the future. Further down the road, I will get a digital camera adapter, a collimation lens and some higher quality viewing lenses and perhaps a dielectric diagonal. Though I want to eventually get a large GoTo Dobsonian and I always lust after a nice, large Apochromatic telescope with a solid EQ mount for astrophotography,for now I am very happy with my NexStar 127 SLT Mak. I will update as I do new things with the Mak or as I learn new things that may be of interest to buyers. May your skies be clear and dark. Iñigo de Oña Nome de plume

Ay izlenimi çok iyi kusursuz gösterim yıldız haritanı varsa neredeyse tüm yıldızları görebiliorsunuz jupiter ve uydularını net görebilirsiniz zoom yapmanız gerekiyor beğendim efso bişi

Me encantó el telescopio, ha cumplido mis expectativas totalmente. Me ofrece una nitidez increíble y eso que sólo lo he podido probar sobre Marte y no estamos en los mejores meses para observarlo, ya que está muy lejos de la tierra. Pero esperaré con ansias a septiembre cuando Júpiter y Saturno estén a buena distancia para poder ver de qué es capaz este equipo. Cuento con un CPC 1100, pero es super pesado y me cuesta mucho salir al campo, salvo que las condiciones de cielo para observación sean las óptimas, no vale la pena sacarlo, pero este Mak 127 es super portable y no cuesta casi nada salir y observar; aclimata rápido, en una media hora... así que en lo que preparas tus conexiones, tus oculares y barlow, el aparato está con la temperatura ideal para mirar el cielo. En espacio profundo se ha comportado bien, me dio imágenes geniales de Messier 3 a medio aumento y de Messier 42 a bajo. Contras: no tiene una salida a 2 pulgadas, por lo que no he podido usar accesorios pro como mi barlow 2.5X a 2". La verdad habría sido un muy buen plus el que hubiera tenido salida a 2 pulgadas, pero por lo demás el telescopio es muy bueno. La óptica de Celestron es buena, así que este Mak puedes estar seguro que te da la mejor relación calidad-precio. Y tuve suerte de agarrarlo a un precio justo, $13800, porque ya lo había visto antes en precios muy locos, ojalá que vuelva a estar disponible a precios razonables.

كل شيء يجننن انصح فيه ومن هذا البائع بالذات تعامل راقي ووتواصلون معهم بعد الشرائي عن اي شيء تحتاجونه

I'm not professional, these are just my impressions. WARNING 1: this might be a begining of an expensive hobby! You will likely want accessories, filters, eyepieces, and maybe larger aperture for deep sky. Search for what you can see with a telescope (especially if you're interested in Nebulae/galaxies) if it's you first one to manage expectations. WARNING 2: you won't see details and colours you see in pictures online including mine (except maybe for Moon). Cameras are far more sensitive and have longer exposures than our eyes. Search Orion Nebula or M81 through a 5, 8, 10 inch telescope for example to have an idea and compare with pictures. Overall, I'm very happy with the telescope, optics seem quite good without noticeable chromatic aberrations, tracking is OK with options to fine-tune during use. After using this, I'm curious to try something with a larger aperture to see more details in deep sky, but it doesn't mean I'm enjoying this telescope any less. For me it hits a good balance of power, ease of use, and portability. Though 8-inch aperture ones would probably last you much longer if you're going to get into the hobby more seriously, those are much more expensive and heavy. You are paying a premium for goto functionality and compact design compared to some other 5-inch options, but I found goto to be very helpful especially at first. This vs a Dobsonian: Observing with a tripod is so much easier especially when what you're looking at is low. Optical tube is much more compact compared to Dob of comparable aperture and f-ratio, but later would probably be cheaper. As far as I can tell, a typical Newtonian reflector would be far less tolerant to collimation issues than this design. Learning with this is certainly easier. If it's your first telescope - be prepared you won't see the colours and details you see in pictures online. Those are captured with cameras with longer exposures and higher sensitivity than human eyes and are heavily processed. This being said, I got this picture of Orion Nebula with an old unmodified DSLR through this telescope in a single exposure, no stacking or additional hardware. What can you see? Moon - amazing! Very bright, very sharp clear small details, no weird colours. Planets - they appear about small pea-sized, rings of Saturn are clearly visible, as well as bands of Jupiter (in colour). You can get them bigger with additional eyepieces or Barlow lenses, but with ones I got (admittedly not the highest quality) I couldn't see more details - same thing just bigger and a little blurrier. Deep sky objects - probably the coolest thing to photograph, but visually seeing it for the first time it's amazing how dim those are in general. I could see Orion Nebula and some other DSOs. In Orion Nebula I could see general shape, but no colour when observing from Peak District. You can probably see more from a darker site, but I haven't tested it. Overall the aperture is considered small for visual DSO observation, but I could see something. Moon, snow, atmospheric conditions (e.g. turbulent air) will all affect your observation. Relative positions of earth to other planet also affects the details you see. Mount, focuser etc: I've read complaints about the mount not being sturdy enough online. It's definitely more shaky than a heavy Dobsonian, but for me it's perfectly useable. You do need to wait a couple seconds after adjusting focus for it to get stable, but you absolutely can get clear view and pictures after that. GoTo depends on how good your alignment is and has couple clever features - there is a "precision goto" option in the menu where it first navigates to nearby easy to see object for you to correct error and then it goes to actual target. Mount doesn't fold flat with optical tube as SE model does. The tripod is a bit bigger than a typical photo tripod when folded. If you're thinking of getting this and using mount for later optical tube upgrades, search for mount limits - you probably won't put much more onto it. I've read online people ignoring limits and putting 6se and even 8se on it, but it will be even shakier and I have no idea how long it will last if you did it and I doubt warranty will cover it. You need to align red dot finder and the telescope before observation, otherwise finding anything is very difficult. The mount is Alt-Az, as opposed to equatorial if it makes difference for you.
