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.

As a former professional astronomer and user of other amateur telescopes I bought this to try and introduce my children to observing and am mainly comparing this to a 6 inch Newtonian reflector with an equatorial mount which has served me well in the past, but is very large and heavy to set up, so an easier alternative was called for. The first night I used this I was hampered by cloud, so could only do a basic setup and some initial lunar observing, but I was pleased to find that this was easy to set up in a short period of time, using the quick setup guide. The lunar views I got were excellent and my kids (and even my wife!) were enthralled with the first views of the moon that we obtained. The second night, although cloud was again an issue, I managed to set the scope up fully. the set up was easy, following the instructions, although it is sometimes tricky to remember that the arrow buttons are only used for controlling the movements of the scope from the handset and not navigating the menus, however they were largely self-explanatory and made the initial setup easy. I would advise using a custom site for alignment using a smartphone with GPS (almost ubiquitous these days) to obtain the precise location, just remember you will need the location in degrees, minute and seconds of arc, rather than decimal. This is quite easy to find with a quick internet search on a smartphone however. Exact times from a reliable source, such as a synced smartphone is also required, along with your time zone. Once these are in you can choose to align the scope using any three bright stars or other celestial objects (moon or planets), simply align the object in the finder scope, then centralise in the eyepiece and align using the handset. This was done in minimal time, even with poor visibility due to cloud and the computer accurately aligned the scope at the first attempt with no need for firmware updates or similar for the handset. Following alignment I used the sky tour to find appropriate objects and after checking that the sky model was correct (it was able to find the moon without difficulty in the solar system mode) I used the handset to move to Andromeda, which was visible as a fuzzy patch, despite poor visibility and quite bad light pollution. The tracking seems to work fairly well and will keep an object in view for a significant amount of time (quite sufficient for real-time observing using the eyepiece), but did exhibit some element of drift, so would not be suitable for deep sky astrophotography, but this is to be expected with an alt-azimuth mount, as compared to an equatorial setup. Unfortunately, the sky conditions deteriorated further preventing any more testing on other objects, but overall this telescope is easy to set up and provides a quick means of finding astronomical objects. As a starter scope at a reasonable price it would seem that it is difficult to beat. In terms of power, I did buy the external battery pack which allows extended observing and this seems to be the best way to power the scope as while using the internal 8xAA batteries would avoid any problems with cord entanglement, the lack of battery life may limit it without a substantial supply. Cord length and wrapping would be even more of an issue with a mains powered supply and could be problematic for anything more than a small distance outside. The scope does need power to operate though and cannot really be operated without it, which is definitely a downside if you were wanting the use it in an unpowered alt-azimuth mode. Overall, this seems to provide a good observing experience for the aperture and price and is highly recommended for a beginner. Obviously, you could get a larger aperture without the goto function for the same price, but this really wins on convenience. I look forward to may happy nights observing with my kids in the near future.
