This telescope can be collimated easily by eye, if you want to collimate with a laser, you'll have to remove the corrective lens in the focuser tube. If you love to tinker knock yourself out however, this isn't the most powerful scope you can buy so, eye collimation is more than enough to be happy.
2) The finder scope is unusable
While I agree, it's not the best finder scope out there and lining it up with the telescope can take a long time but, it is possible with time and patients. It's also replaceable so if you don't like it, get another one. (note: it is a scope and not a finder, the image is reversed in the finder)
3) I can't see anything out of this thing
You need to collimate the scope and line up the finder scope, the instructions are in the manual for eye collimation (tip: back the focuser tube all the way out when you collimate, doing this will let you see both the secondary mirror and the primary, also note, this went through shipping and if it arrived with all the mirrors aligned and ready to go, get a power ball ticket because you'd be the luckiest person on the planet
4) The Barlow is useless
Please google and youtube what a barlow is and how to use them, it's not a true lens and once you find out its true purpose, it'll make more sense
5) The 4mm lens is useless
See my comment on the barlow, using the barlow with the 4mm will tame things a bit, also, get a lens and filter kit with a 15mm and a 9mm lens.
6) The Telescope doesn't stay put on the tripod.
The counterweight on this telescope is not for looks, you need to use it to balance the telescope on the eq mount. when the counter weight is properly balanced, you can put the telescope in any position on the right ascension axis and it'll stay put. The Telescope itself also has to be balanced front to back in the mounting hoops (youtube it, there are a billion tutorials on how to do this.) One last comment on this issue is, do not try to push the telescope into position with the clutches locked, use the controls on the tripod to position the scope, if you need to make big adjustments, loosen the clutches (should be OK because your telescope is balanced) position the scope to the general area of viewing, lock the clutches and use the controls to fine tune. If you push the scope around with the clutches locked you're manhandling the gears that the controls are attached to and you can push them out of whack, don't do this.
Here's the deal, this is a marvelous telescope for UNDER 200 American green backs!!! When properly set up, balanced and overall ready to view, it's a great scope and it's a lot of fun. Buying upgrades for the scope will add to your viewing pleasure. Yes you can see our planetary neighbors, the moon looks fantastic, in a dark place, you can see some deeper space stuff.
Is this a good scope for beginners? Yes I think it is, backyard astronomy is not a plug and play out of the box and looking at Jupiter kind of deal. A telescope is a pretty sensitive thing that takes a little love. If you're just starting out and collimation, calibration and generic tinkering is not your thing, this may not be your hobby, heck aside from sitting on the couch, I don't know what hobby doesn't require a little hands on setup and tinkering.
Finding stuff in the sky is hard, small movements at the scope have a huge impact on where you're looking in the sky, youtube is your friend, so is google.
Update 01/01/17: I am slowly getting this scope into alignment. If you're new to Newtonian telescopes and you're going to insist on buying one of these I urge you to get a collimation tool. I bought a laser, but I probably would have been better off with a Cheshire.
You cannot be afraid to take this telescope apart, because you will be doing it a lot before you actually get to the point where you can take it outside and see things. It is a time consuming process because the nuts are not welded to the large tube. The first thing you need to do before proceeding is take out the lens at the bottom of the focuser. You can do this by extending the focuser all the way out and removing the three screws holding it to the tube being careful not to drop the nuts. After removing the lens reinstall the focuser and retract it until it hits the stop. If your telescope was like mine, you will notice that the small secondary mirror is WAY forward toward the primary mirror instead of centered on the focuser. At this point on page 26 of the instruction manual it will tell you "DO NOT loosen or tighten the center screw in the secondary mirror support". Ignore this instruction. Move the mirror back toward the spider (or forward away from the spider if your mirror is out of alignment in that direction) until the secondary mirror looks round and is centered below the focuser. You will have to loosen and tighten all four screws to accomplish this task.
This is the point where helpful people on the internet, particularly two guys in Australia on YouTube, were a huge help. As I said, I bought a laser collimator. What you need to do is remove the spider (this holds the secondary mirror) and then remove the primary mirror, being careful not to touch or drop the mirror. I found the primary mirror to be mounted very close to the center (I was eyeballing it, but still). There are four holes for the screws that hold the mirror mount to the tube. They appeared to be equidistant from one another (again, eyeballing it), so I got some string and tied two pieces across the opposite holes. I then took a felt tip marker and placed a dot where the two strings intersected. Then I removed the strings and placed a plastic adhesive paper hole reinforcer on the mirror making sure to place the marker dot in the center of the hole reinforcer. Trust me, you won't see any of this stuff when you get ready to look at the heavens. I then used the adjustment screws on the mirror holder to snug it down to the rubber spacers on the mount. When you're done, the locking screws will stick out. Now put everything back together.
Isn't this fun? Remember, this telescope is being marketed to first time users looking to get into astronomy, hence the reason my rating is still and will always be one star.
Here is where the collimation laser comes in. I had attempted several times to collimate this telescope without that little paper hole reinforcer I told you to put on the primary mirror, because I didn't know it was supposed to be there or how helpful it would be to have it there. After making sure the laser collimator was true (easy, and luckily it came from the factory not needing adjustment which is probably the only break I got in this process) install it in the focuser with the target area facing the back of the telescope toward the primary mirror and turn it on. I used setting 3 on mine, which allowed me to see the laser clearly in the primary mirror. BEFORE you look down the tube looking for the beam on the primary mirror, stand to one side and move your hand over the opening of the telescope. If you see a red dot on your hand be EXTREMELY careful looking down into the tube. The spot where you see the dot is the dangerous place, so definitely don't look there. Your next task is to move the three screws on the secondary mirror to move the laser beam to the center of that paper hole reinforcer. Get it as close as possible. Next, move to the back of the scope and loosen the three lock screws on the primary mirror. Then move the three adjustment screws (good tip here from someone else on the internet: adjust these screws by TIGHTENING them. Loosen them only if you really have to) to center the laser beam on the target of the laser collimator.
When you have finished this task you're done, right? Nope. Look down the front of the tube again and see if that beam is still centered in the primary mirror. It wasn't for me and I had to adjust the secondary a second time and then readjust the primary again. Then it was centered. So now you're done because lasers are really accurate, right? Nope, but you are a lot closer than I was the first few times I tried my hand at collimation. Next, take the focuser back out, replace the lens you removed, and reinstall the focuser.
Now you have to take the scope outside and aim it at a star. Use an 8 mm eyepiece, or use a combination of Barlow and eyepiece to get close to 8 mm. The manual will tell you to find Polaris and center it in your eyepiece. Why? Because Polaris appears stationary to a ground observer looking through a telescope. All of the other stars appear to "move" (actually, you're the one moving along with the surface of the earth as it rotates on its axis, but most people don't care about the physics - for them the stars move). The problem with Polaris is that in light polluted skies it can look pretty dim, and where I am in Afghanistan (Kabul) that is a real problem along with all of the dust and smoke in the air. So I picked a brighter star which complicates things because of the apparent motion, but allows you to easily see what it is you are supposed to be looking for next so for me it was worth the extra effort involved. In any case, center the star you picked in the eyepiece (this won't last long if not Polaris - see what I mean by "extra effort?) and defocus until you see a circular glob of concentric circles. They probably won't be concentric yet which is what you're going to fix next, but if they are, stop because you're done.
Something worth noting here: allow your telescope to cool down (or heat up) to the outside ambient temperature before looking at the glob or attempting further collimation. You're wasting your time if you don't follow this step.
Now go to the back of the telescope and loosen the lock screws. Making sure the star you picked is still centered in your eyepiece move the adjustment screws until the circles on that glob of light are concentric. As you adjust a screw the star will move away from the center of the eyepiece. Make ONE small adjustment and then recenter the star in your eyepiece before making another. Remember to try make adjustments by TIGHTENING screws as opposed to loosening them. Another hint: looking on the glob, when the circles are not concentric you will see widening spaces to one side. Adjust the mirror in that direction then recenter in the eyepiece. Take your time doing this. Not getting it right is not an option if you want to use this telescope and it will take time unless you are naturally good at this sort of thing. I'm not, it take me quite a few hours over a couple of nights to get it OK and I still have some work to do on it.
All of my detrimental comments aside, I am enjoying learning about and using this telescope. Would I recommend it to a beginner like me? Absolutely not! If you are a beginner and want to look at things "out of the box" get yourself a refractor and spend as much as you can afford on it. Believe it or not, I had a lot more fun with the Celestron 70 mm travel scope than I had with all the headaches I've gone through with this one. Easier to use, easier to maintain, no collimation required. I did have to upgrade the tripod and add a small finely adjustable tilt thingy to get around the pain of pointing it at what I wanted to see and keeping it pointed there, and that cost more than the telescope itself but it was worth every penny. Is this telescope better than the travel telescope? Hands down, once you get it at least somewhat collimated as mine is now, but it is a huge learning curve!
(119 usd plus 82 dollar shipping) = 201 usd lesson for me
NOTE dont even buy bird jones type reflectors that use spherical mirrors and a lens in the focuser tube. buy parabolic reflectors there are much much easier to use

When the package arrived, I could tell that the telescope would be quality - the box weighed over 30 pounds. Almost everything is made of metal - the telescope body, clamps, mount, tripod, eyepieces and adjusters. There are few plastic pieces here and there, like the flexible adjuster extensions and some parts of the tripod, but otherwise, everything feels sturdy and well-made.
The main point of contention with an equatorial-mount telescope is the setup. If you follow the quick setup guide closely, you should have no problem getting everything put together - just take your time. The trickiest part of the setup is lining up the small finder scope with the main telescope. Here's a tip: during the daytime, find a distant object somewhere on the horizon. Try to line the object up the best you can with the main telescope. Next, locate the object in the finder scope and centre the cross-hairs on it. It may take a some fine tuning, but once you got both scopes lined up, it's much easier to point the telescope at something in the sky.
Once the scopes were lined up, I was able to point the telescope at the moon for some amazing views. I recommend looking at a partial moon so that you can see variations in the shadows; the 127EQ is very capable of spotting craters and fine details with its default eyepiece - my girlfriend and I were very impressed! We have yet to try the included 3x Barlow eyepiece, but it should offer up some incredibly-detailed views.
We haven't learned how to properly set up the EQ mount in order to track stars and constellations yet, but it doesn't seem to be too difficult if you're willing to learn something new. There are lots of videos on the internet about how to properly align the telescope with the stars, but I could see that being a turn-off for someone who wants something instantaneous or automatic.
Overall this is a great telescope, but it might be a bit intimidating to use for some. Put the effort into though and it's well worth it.
In my opinion the telescope is good value for the price. Yeah, it uses a bird-jones design with a corrector lens to correct spherical aberration, but I have to say it produces some good results when coupled with good eyepieces. The focal ratio (f/8) makes it a good all rounder for looking at the moon, planets, and deep space objects.
Collimation isn’t impossible with this telescope as most people say - you will need to remove the corrector lens from the focuser before laser alignment. I have found the focuser to be sloppy i.e. it does not sit firmly in the focuser tube making collimation difficult. However, you can use more teflon strips in the focuser tube to fix this problem
The mount itself is pretty good, though the RA slow motion control is difficult to turn probably because the telescope is slightly too heavy for the mount.
To conclude, this telescope is probably not for a beginner - it’s more suited for those that don’t mind a bit of tinkering and want to cut their teeth with an equatorial mount. Yeah, it’s not perfect, but it’s pretty good for the price and gives pleasing results.
La calidad del telescopio es buena con relación al precio, aunque si me gustaría que fueran de mejor calidad las perillas y del buscador (Finderscope), ya que es muy pequeño y un poco complicado de usar ya que las imagenes están invertidas.
Si pretendes sacar el telescopio de la caja sin estudiar previamente como alinear la montura ecuatorial, resultará casi imposible enfocar algun objeto en el cielo. Recomiendo leer primeramente como alinear la montura ecuatorial y si cuentas con un laser (de color verde) es muy sencillo localizar objetos en el cielo.
Tengo unas semanas con el telescopio, he conseguido observar a Jupiter (con sus 4 lunas más grandes), Marte (con una de sus lunas) , Venus, la nebulosa de Orion, las Pleyades, la luna, entre otras estrellas.
Si tienes poca experiencia en localizar estrellas en el cielo, Celestron te da una suscripción a Starry Night (Edición básica) programa para PC o MAC, la cual te muestra en tu computadora las estrellas visibles en el cielo del lugar donde te encuentres y permite localizar de manera rápida constelaciones, estrellas, planetas entre otros. También existen otras aplicaciones para Android como SkyPortal (de Celestron), Star Walk 2, Skymap (de Google), entre otras.
Había leído que antes de comprar un telescopio recomendaban la compra de unos binoculares para localizar las estrellas y constelaciones. Yo compré el telescopio primero y he podido observerbar varios objetos, pero,estoy por comprar unos Celestron Skymaster 15x70 para ayudarme a localizar más objetos en el cielo para después poder observarlos a detalle con el telescopio.
Para concluir, recomiendo en gran manera este telescopio, llegó una semana antes en excelentes condiciones y bien colimado. La calidad con que puedo observar los objetos es muy buena, se pueden ver con gran claridad los crateres de la luna y demás astros. Recomiendo el uso de un laser para localizar las estrellas ya que como mencioné el buscador me resulta complicado de usar. Si pueden adquirir unos binoculares 10x60, 12x60 o 15x70 serán de gran ayuda para explorar el cielo, para después observar a detalle con el telescopio. También recomiendo una brujula y nivel para alinear correctamente el tripie y la montura ecuatorial.
Disfruten del cielo.
I quickly discovered that I need more quality eyepieces to help my experience.
The 20mm eyepiece is still the one I use first to find my objects, before zooming to a smaller one.
But, the provided 4mm eyepiece is almost unusable, too small, too much blurry zoom, and very hard to align your eye on it.
The 3x barlow can be used with the 20mm to increase its power.
To have a better experience, you should buy another eyepiece.
I suggest the 3-pack svbony 4mm / 10mm / 23mm 62 degree eyepieces
Or the variable 8-24mm
Then, the tripod...
After only a few hours of use, it started to be very hard to use slow motion controls, these are too hard to turn.
Finally, I found the solution: You need to always bring with you a 11/16 ratchet, and
tighten the nut almost every time you use it, and it should need to be tighten a lot of times on the same night.
So, I still suggest the PowerSeeker 127eq, but with the 8-24 eyepiece, and don't forget your ratchet!
