NEXSTAR 130SLT Computerized Telescope

The telescope delivers what it promises. I gifted it to my husband and it works like a charm. I bought it in April 2021 and then it costed me around 70k, totally worth the value. We have seen many celestial objects like Moon (with its craters), Mars, Venus, Saturn (distinctly identifiable because of the rings), Jupiter (along with its 4 big moons) and many phenomena like super moon and solar eclipses. Great purchase. Attaching some of the pictures that we took from our phone.

Very excellent product I could see Orion nebula , Andromeda Galaxy as well as Neptune through this telescope I hope to start my telescope missions as you can see I own Celestron powerseeker 60az refractor telescope on my first image and next this scope so I'm gonna to start my mighty dare school voyage for teaching kids via entire district and state ,this scope is not for my purpose this scope I bought to teach school kids whoever don't know what is telescope?

Packaging was good. Received a new piece. Working superb.

Product s good but I was expected complementary product

As expectation, quik to assemble and essy to operate. Resolution is quite good. Moon caters looks very fantastic. Jupiter with 4 moons looks awesome.

It is very very good.

Is it helpful for the bigenners

Last week I received my NexStar 130 SLT. I made the decision to buy this scope based almost entirely on the recommendations of reviewers both here on Amazon and elsewhere. This is my first telescope, and I will say will say up front that I am completely happy with this scope! Regarding the negative reviews, I can sympathize that in some cases a truly defective article can arrive. For many, I would suspect that the issues encountered were largely of their own making. While in the main, this scope is relatively simple to set up and use, it still helps to have at least a modicum of technical skill (a healthy dose of common sense will help too!). The evening I received the scope (15 July) I set it up on my deck. Yes, not the most stable of platform, but I live in a dense neighborhood with lots of obstructions and murderous light pollution. The star alignment, using the 3-star "Star Align" process, took me two attempts. I blame my ineptitude with the use of an eyepiece and not having stars truly centered in the field of view for this. Regarding this, I think an eyepiece with a crosshair would be excellent for performing these alignments. (Another night I had multiple failures. This turned out to be related to the incorrect time, which was off by a few hours. The system will apparently remember the last values you entered. Be advised, they will not update and will be incorrect. Check your time and date each time you power up the system! (Many complain that the system does not retain the time once it is entered. I would venture a guess here as to why. The simple truth is that it would drift off of "real" time within a very short matter of time. Maybe adding the optional GPS module would fix this problem, but the internal NexStar clock is simply freewheeling and will inevitably be off the longer it ran on its own. Having to re-enter it each time you power up ensures that time is not an issue during the alignment procedure. Imagine your frustration if you took tons of time aligning each star in your eyepiece, and despite your best efforts the system would not align? Re-entering the time alleviates this factor, assuming you enter it correctly!) For my location, I simply plotted my deck in Google Earth and wrote down the coordinates. This seems to have enough fidelity for the star alignment to work. Once I had the telescope aligned I picked a random bright object in the southern sky to examine. Imagine my surprise when the first celestial body I have ever viewed through a telescope turned out to be Saturn! Using the provided 9mm eyepiece, the rings were clearly visible. I had not yet received my collimation eyepiece, so I was worried that it might need an adjustment. No adjustment necessary on my scope at this time! I am looking forward to viewing through higher-quality optics though. Regarding the stability issues that many have commented about. Yes, images do move about quite easily, especially on my wooden deck. I have not yet weighted the tripod or gotten a set of the damping pads. I will say that image stabilization is not completely unbearable on my scope. In just a couple of seconds after making a focusing or alignment adjustment, images became still enough to view nicely. I can only imagine this will improve with weights and dampers. I do see why this scope would not be ideal for astrophotograpy though. I would think it would not be impossible, but you would have to ensure the scope is deployed on a solid foundation and go to great lengths not to disturb the scope in any way. I was able to configure and control my scope with Celestron's enclosed NexStar Observer List (NSOL) software and the freeware Stellarium packages relatively painlessly. Install the drivers that come with your USB-to-Serial Port adapter. (The computer interface to the NexStar handset requires a serial RJ-11 phone jack. Celestron sells a cable with an RJ-11 phone connector on one end and computer 9-pin RS-232 serial port connector on the other. Most likely your computer/laptop will not have a serial port, so you will have to further adapt this to USB) My laptop configured the COM3 serial port, but your mileage may vary depending on your system. Make sure to restart your computer once the drivers are installed. Truth in advertising, I tested my scope indoors using an arbitrary alignment. The scope tracked and moved what seemed to be the proper azimuths and elevations for the objects I selected in the software. Any issues I find in the wild once I get the scope outside again can likely be mitigated with the anti-backlash settings for the motor drive. If there is anything significant I find, I'll make an update! Regarding some of the slewing, anti-backlash, and cord wrap settings, I would have appreciated a little more information in the manual as to what the settings actually do and how they work. I did see an example where my scope attempted to go the long way around counterclockwise to a position that just should have been about 10 degrees clockwise. This was very likely due to bad settings in the aforementioned utilities. I made a few tweaks after that and the problem seems to be alleviated, though I am not exactly sure which setting did the trick! :-) At the end of the day, I have to say that for the money, this scope does everything it is intended to do. Have some realistic expectations going in. You are not going to get Hubble Space Telescope views out of this scope! But you will get a lot of enjoyment out of it if you take the time to set it up and align it properly. I did get a good view of a deep space galaxy, which as many have stated, was simply a distant smudge of stars. However, it was clearly visible amongst the background of distinct stars.

Good enough to see Moon and Sun but planets require more Zoom capability.

El telescopio llegó antes, completo y bien empacado. Después de probarlo he verificado que funciona perfectamente. Recomiendo que compren además algunos oculares adicionales, filtros y muy importante, una herramienta de colimación. Para mayor rapidez y comodidad compren un colimador láser. Es muy probable que los espejos lleguen desajustados por el viaje hasta nuestro hogar y es indispensable hacer los ajustes en la óptica. Esto es parte del mantenimiento cotidiano de los telescopios reflectores. Creo que es ideal para principiantes e intermedios, sobre todo valoro las funciones de auto tracking para seguir los objetos y no tener que estar ajustando la orientación del tubo a cada momento. En las primeras de cambio, pude ver Júpiter y sus lunas, distinguiendo las bandas y también Saturno distinguiendo los anillos. Ojo: no esperen ver en el ocular una foto de revista astronómica; hay que tener las expectativas correctas y aún así la experiencia es sobrecogedora. No olvidar que el telescopio viene con oculares de 9 y 25 mm que les darán aumentos 72x y 26x respectivamente. Suficiente para planetaria y cielo profundo sin grandes pretensiones. Compren igualmente una Barlow 2x y 3x para aumentar las posibilidades de enfoques más potentes y sobre todo serán útiles si quieren hacer astrofotografía. Yo compré anillo T y adapté sin problemas mi cámara DSLR con ayuda de la Barlow para lograr enfoque y saqué algunas Buenas fotos de la Luna. Quiero mencionar que después de pasar mucho tiempo investigando cuál podría ser mi mejor opción, me decidí por esta joya porque es un f/5 muy luminoso, sirve para cielos profundo perfecto y un poco de planetaria. Además tiene sistema GOTO y auto tracking lo que te facilita la vida buscando objetos y manteniéndolos en foco todo el tiempo. El soporte tiene adaptador cola de milano por si quieres montar otro tubo. Optaré por comprar después un MAK para ver planetaria de forma más poderosa. En resumen, un telescopio muy recomendable.

El telescopio es un regalo para mi marido, es el primer contacto que tenemos con la astronomía. Después de leer en varias páginas para encontrar o asesorarme sobre que telescopio comprar me decidí por un telescopio newtoniano, y seguí buscando telescopios de la marca celestron, encontré este a muy buen precio llego muy rápido y perfectamente embalado, una vez abierto viene con las instrucciones en inglés, el mando del telescopio se puede configurar en varios idiomas y su montaje es muy sencillo y rápido. Hemos podido observar la luna y la verdad que se ve perfecta y con una calidad de óptica muy buena, eso sí recomiendo el kit maletin celestron de filtros y ocular, ya que el telescopio en sí está muy bien pero sin este kit de oculares no se le puede sacar rendimiento.
