21062 AstroMaster 70 EQ Refractor Telescope

amazing details

Failed to get a full refund to a faulty returned product

The installation is sooooo complicated. It’s been 6 months and I couldn’t do anything with this $1000 gadget. I later realized some parts are missing but now I’m in a phase where I can even return this item :(

not usable

المنتج رائع ومثالي للفئه الهاوية للتبع الكواكب النجوم مع اخذ الاعتبار بامتلاك عدسات مناسبه اضافيه

Cavalletto poco stabile di bassa qualità. Puntatore non funzionante. A differenza di quanto descritto nelle istruzioni l'obiettivo da 20 mm non ha alcuna parte in acciaio cromato. Dal mio punto di vista il costo non è adeguati alla qualità del prodotto.

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.

Çok iyi bir teleskop. Başlangıç için 50AZ modelini almıştım ama arasında çok fark var. Andromeda, jüpiter, saturn ve niceleri telefonumda var ama "AMAZON TÜRKİYEDE RESİMLERİ AÇSA GÖSTERECEM!" Eğer çok üst segment alıp para basmayacam diyorsanız ideal. Çok ekmeğini de yedim ürünün ;) 2 eksisi var el ile taşınmaz çok ağır. Ekstra lens alıp geliştirmek lazım. Jüpiterin 2 büyük çizgisi ve büyük kırmızı gözü lens yardımı ile gözüküyor. Ayrıca fotozeynep ile 1 günde kapınızda.

The telescope is fantastic with great potential. Pulls in an abundant amount of light. Moon looks stunning and I saw jupiter... sort of. I was able to focus it in and even sorta make out the gaseous nature of the planet, and I saw one of the moons. Blurry though at high magnification. All in all, is it worth the price? Definitely! But you'll do yourself a favor making the extra investment Buying an eye piece kit. If you want to see planets, Plossl eye pieces would be the way to go along with light filters. It's difficult but doable to make out the gasses on Jupiter but to really pull in it's detail, you'll need filters. High quality eye pieces like Plossl will be my next purchase so I can push this scope to it's limits which seem far beyond what the included eyepieces can offer. Oh yes, the star finder thingy. It's like using a red dot scope on a riffle. It's a bit of a pain to use but sight it in on a terrestrial object (land) far away first, converge the two dots and it'll put you right on that object. I used it to find Jupiter and it worked well. It took less than a minute to align the scope on it so it did it's job. The tripod. It works nice and all but very shaky. Basically, you have to center it in and don't so much as breath on it and look through the scope. Kinda a pain when you have to touch it to keep it tracked in as the object moves away as the earth spins. Anyways, good beginner set up. Get a high quality eyepiece set to take it to the next level. I gave it Five stars because the Scope for the Money you pay is just Fantastic and this could be an Excellent set up with the high quality eyepieces, filters, and maybe a sturdier tripod if that's an issue for you.
