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.
I should add that the telescope had probably traveled a few miles around the globe when it got to me, but the box and packaging were in pretty good shape when it arrived.
When I got it, I initially compared it to another $50 reflector, the Celestron 76 mm Discovery, and the results were very disappointing, the smaller one was much sharper. I spent hours reading on the Celestron and other sites on how to adjust collimation with a simple "hole in the cap" and got nowhere. The image was always relatively blurry. Day or night, polaris or no polaris.
I later bought the Celestron 24mm to 8mm zoom eyepiece, which allows me to zoom in without changing eyepiece, and it works very well on the smaller 76mm telescope, but again blurry images on this one.
After quickly becoming an expert on reflector collimation, I noticed that nothing seemed collimated properly. I guess they don't even try at the factory on this one? I decided to order a Celestron 1.25" collimation eyepiece ($30), which can be useful in aligning the optics (the two mirrors) in reflectors like this one. I tried it out on this one, and got repeatedly confused on what should be seen in what reflection when you adjust this or that. I spent entire afternoons fiddling with secondary versus primary mirror adjustments, achieving virtually nothing as far as improved sharpness is concerned. I did replace the secondary mirror alignment screws with better stainless steel ones that would not strip, they are metric m4.
I then tried to collimate this thing on the North Star (Polaris) and that is, for this one, another pure fantasy. The reason is that Polaris is faint, and every time you move a mirror by a tiny bit (as explained in the Celestron instruction) the star just darts out of view in the eyepiece. More frustration and still no luck in getting this thing in focus.
Lastly, I ditched all the Celestron recommendations on day and night collimation (using either the celestron collimation eyepiece or the "ring pattern" for out of focus point sources) and did instead the "EYE-DOCTOR TEST" :
I wanted to see how sharp I can get this one, when there is no wind, no shake, no atmospherics, no moving planet, no mist etc. So I placed the telescope at one end of a long corridor in my house, and a nice clean printed envelope with some sharp text on it at the other end. With this method (which I seemingly invented, as it is not described anywhere in the instructions nor on the Celestron site) I was finally able to adjust (by very small increments) the three screws on the secondary mirror till I FINALLY got a nice sharp picture of the writing on the letter. Note that this last procedure did NOT require the collimating eyepiece! Just the regular 4mm eyepiece that comes with the telescope. Success!
As a by product, I found that in fact in the end all three eyepieces work rather well, down to the 4mm which is a bit faint, the 20mm with the 3X Barlow is better.
Now I can finally see the main two stripes on Jupiter and the Orion Nebula with some clarity. In conclusion:
Plusses : Potentially sharp optics and large aperture. Reasonable price. Sturdy mounts. Useful eyepieces.
Cons: Imo optics needs to be carefully aligned by the method described here. Mine was definitely NOT aligned and, initially, as a result disappointingly blurry.
EDIT: After a few more weeks of use (February 2014), I spent some time using the Celestron collimation 1.25" eyepiece ($28 here on Amazon). My conclusion is that it is a very useful, if not essential, tool for this telescope. To avoid any further issues due to my previous messing around, I first screwed in the secondary mirror (by loosening up the three alignment screws, and pulling in the secondary mirror all the way in until it barely touches the mount), and later pulled out the primary mirror as well(by pulling out all six screws until the whole unit comes out, then reinserting the mirror after making sure the secondary was pointing the right way, straight to the back). Then, using the Celestron collimation eyepiece with its crosshair, I carefully adjusted the secondary and primary orientations (three screws for each mirror) until all the crosshairs overlapped perfectly. In other words, the crosshair in the eyepiece has to overlap perfectly with its reflection through mirrors 1 and 2, and back to the eyepiece. This takes time and patience. After having done that, the image quality seems pretty good and rather sharp. I went down to about 8mm, I don't recommend getting lower than that. The best setup for this one is the 20mm eyepiece, either by itself or with the included 3x Barlow (which then gives 20/3 = ca. 7mm). I also got some Ploessel eyepieces, but they will do you no good if the mirrors aren't aligned first.
PPS. I found (April 2014) that the best way to collimate this (Bird-Jones or catadioptric design)telescope and get nice sharp images is to remove the focusing lens at the bottom of the focusing tube (takes 10 mins), align the secondary and primary mirrors with an inexpensive LASER collimator (mine is an LK1 $30 from seben dot com, takes another 10 mins to do this part), put the corrector lens back in and reinsert the focusing tube (don't touch the lens with your hands, takes around 5 mins). With this method the results are guaranteed to be reproducible and consistent. The images are then consistently sharp.
PPPS. The other day (June 2014)I talked at length to a very nice and helpful person at Celestron technical support (Will?). He suggested to check the following thing. The secondary (smaller, flat) mirror is oval-shape and mounted right under the focusing tube, held in place by three (outside)-plus-one (center) screws. Now put a focusing cap (just an eyepiece cap with a small 1mm hole in the center) at the (top) end of the focusing tube. Then make absolutely sure (after you take again very carefully the correcting lens out of the focusing tube) that the inside of the focusing tube and the secondary mirror, as viewed through the focuser, are perfectly concentric when you view them through the hole in the cap. That is, the secondary mirror has to be perfectly centered when viewed from the top of the focusing tube. Note that the secondary mirror is oval shaped, but will look like a perfect disc when tilted at about 45 degrees. On mine this required several turns on the (secondary) center screw. After this is done, make also sure that the tilt on the secondary mirror is such that you can see the center of the primary mirror (on mine I put a black pen mark at the dead center). Now re-align the secondary and primary mirrors with a laser (in my case), with the cap with a hole, or a cheshire eyepiece. Then put back the correcting lens in the focuser, and you are done. The end result is that on mine it improved the sharpness a bit (I did the eyedoctor test again). I was also able to see more detail on Saturn with a standard 9mm eyepiece, will try taking a few pictures soon.
PPPPS: This telescope really shines (due to the light gathering abilities of it's fairly large mirror) when you want to look at fainter objects. Recently we had good viewing conditions and I had a chance to look the the Great Cluster in Hercules (M13), the Lagoon Nebula (M8), the Omega Nebula (M17), and two more star clusters in the same general region (M4 and M62). I took some fairly nice pictures of these objects with a Sony HX200 camera (30x zoom) mounted piggyback on the telescope, using the Celestron motor drive for the 127EQ and long 30sec exposures at 800ISO. See the pictures I posted on the right. I was surprised how well the telecope mount, equipped with the Celestron $30 clockdrive, works when taking long exposures.
PPPPPS: It's October, seven months after I did the laser collimation, and everything is still fine and exactly the same. That tells me that the collimation on this one only needs to be done once, maybe if it gets out of whack during shipping. After that there's no need - unless you bump it or drop it badly. At least that's my experience.
PPPPPPS: It is end of February 2015 now, and I had some very good views of the great Nebula in Orion M42. The scope is still perfectly collimated since almost a year ago, last time I did the collimation with a laser. Again, the message here is that if you spend the time to collimate it properly and don't bump it after that, it will stay sharp almost forever ... Btw I love the $32 celestron R/A single axis motor drive on these telescope, and in my opinion it is a very worthwhile investment. Objects stay in view for almost an hour w/o adjustments.
After you spent time collimating it, then the views are pretty good for the price you pay. Not great, but you get what you pay for. I could see the 2 main bands on Jupiter and the moons, the rings of Saturn, but struggled to see the Cassini division. The moon looks great. M4 and M13 could also be seen and looked decent.
I highly recommend some better eyepieces. The 20mm with the 3x barlow isn't too bad but the 4mm eyepiece was garbage. Maybe I just got a bad one.
The tripod and mount is the real weak point here. The slightest breezes will cause shaking. With a good polar alignment, the slo-mo controls will help with tracking your object. This is the benefits with using an EQ mount where you will only need to turn one knob to keep your object in view.
The finder scope isn't to great either. It is to easy to bump it and lose alignment with the OTA. The mounting of this finder scope could be better, but it will work.
Assembly of this scope was super easy for me. Barely needed the manual to put this together. It is pretty straight forward.
I am on the fence about recommending this scope. If you don't have any patience, then no. If you have a cool calm head and willing to take this apart and get things aligned, then for $150 this scope really isn't that bad. Like I said, the views are pretty decent.
