Nice for beginners ..
Brought this Telescope a few weeks ago and have been enjoying it ever since. If you are a beginner you will have to get used to aiming it and focusing on objects, and whilst this can be pretty frustrating at first, once you get used to this aspect it becomes more and more enjoyable to use.My advice is to get yourself a 'Barlow' lens, which multiplies the magnification of what you can observe, 2, 3 or 5 times depending on what Barlow you opt for. It's tempting to just go for the 5x straight away, but be warned, until you have sussed things out a 5 x will make objects harder to find and then to keep in the eye piece.If you have got a camera with a long zoom lens, you will know that finding, and then holding anything still at full zoom is hard to do. Telescopes are similar, in that you only have to lightly touch the scope for the image in the eyepiece to shake or even disappear from view. That said, you shouldn't really expect anything different with a basic tabletop Telescope; after all, if you had a couple hundred to spend you would be looking for something much more sophisticated. Maybea scope that found objects and tracked them for you! In my opinion this is a great starter Telescope, which is compact, light and very portable. It requires very little setting up - just put it on a stable flat surface, take the lens caps off and away you go.I took the attached photos with the scope sitting on an inside window ledge. It was fitted with a 2 x Barlow, a Moon Filter, one of the eyepieces that came in the box, and a mid-range Smart Phone (Samsung A51 5g). Took some practice and quite a bit of experimenting, but believe me if an old disabled fart like me can do this, so can you.If you buy one, I hope you master it and enjoy using it. It's a really good feeling the first time you point it at the moon, look through the eyepiece, focus it and and see the surface close up!

Ridiculous value for money.
At £38 a Telescope like this is insanely cheap, at double it's price it would be a reasonable purchase. If you're interested in astronomy and are looking for a simple telescope to start, or already own a larger telescope and are looking for something more portable, (provided the price hasn't drastically increased) this is perfect.

Good beginner telescope, easy to use and assemble.
I’m not an expert on telescopes and bit worried I wouldn’t be able to use this but the online instructions are good and clear and there’s not much assembly to do. Just attaching the laser targeter to the top really.This telescope is good in daylight with small opening but works much better at night with large opening. The instructions stress how much better the telescope will work in a very dark place away from all the background light but it does need to go on a table. We live in a rural area but have just been using it in the back garden with all the lights we have control over turned off and seen some good stuff.Targetting system works well but but is annoying that it is in different plane to main eyepiece so you end up twisting your neckIt moves a bit too easily so you have to be careful not to nudge it.Easy to focus.The grease on the eyepiece is sticky and easy to get on your hand.Pity you can't easily mount it on a standard tripod.

It is an excellent piece of equipment!
Was bought as a Christmas gift, so not for myself. I have had glowing reports how good it is though. The person it was bought for absolutely loves it!

Well worth it
Very easy to use

Seems OK but lenses are not great.
The telescope seems well built, I have not had too many clear nights to fully test but when I have tested I would say that you need to invest in a Barlow lens and possibly another higher magnification lens, I bought for my son who is 8 and unless he starts to see better images he will probably soon get bored with astronomy.Maybe it's me but the images that are shown are way above anything I can achieve with the supplied lenses and I don't think I am doing anything wrong. I will get a decent barlow lens and a higher magnification lens and rewrite my review, but as of now I just see an enlarged image of the distant moon.

Great gift
This was for my husband's birthday and he loves it.

Decent just one thing
Unit works well and we enjoy it. We love the small size and ease of taking it anywhere (I downsized from a bigger scope). My only complaint is that I noticed an imperfection (small black spot) on the primary mirror - however it doesn't affect the view (only light gathering ability) so my only suggestion is to peer down and check the mirror when you get it. I didn't bother replacing it, personally. It works fine.

I picked this over the Celestron FirstScope
For reference, I am a complete beginner. I did a lot of research prior to getting one of these. After stumbling on r/dontbuyapowerseeker, I felt very lost in the process of getting one. From what I've learned over research, dobsonians are the way to go. They're the best bang for your buck and this particular model doesn't stray away from that. While buying this, I also had bought a Celestron FirstScope. I figured I'd test both to see what works better for me. They both are fantastic beginner telescopes. However, the FirstScope was lacking a few areas that this one fulfilled which is why I picked this over that. I do believe the price difference is well worth the added benefits. So, with that being said, let's get into this.The Good:Lens: The lens that come with are two wide angles that are 10 mm and 17 mm. Both are perfect for viewing and are great for kids since it is so wide that it gives a lot of room to look around. All the pictures taken with exception to the Flame Nebula, were taken on these lens.Portability: The scope itself can be taken off of the clanky mount that its on. This is especially handy when trying to transport the telescope since the mount is awkwardly shaped that it wouldn't really fit in any case. I have yet to find a case for this exact scope, so I made my own out of an old suitcase, but it's not necessarily a necessity. You can perfectly transport this anywhere you'd like.The red dot piece: Probably one of the most underrated tools of a dobsonian, especially when this small, is the red dot finder. You'll find it very hard to use a finderscope with the awkward shape of the dobsonian so it is very nice to have simple red dot sight to angle the telescope at a given location. Just make sure to turn it off one you're done so you don't drain the battery. It really feels like a GPS tracking telescope with how easy it is to find objects with the red dot.The eh:Viewing capability: This is purely based on what comes out of the box. The viewing power is better than the First Scope just because it is a larger and wider, but the scopes that are provided don't get you much magnification for any close ups to planets or deeper space objects. I'd recommend getting a good Barlow lens with this and something lower in mm. A 6 mm or 4 mm will dramatically increase your magnification and with how wide the scope is, it won't compromise brightness significantly. The picture of the nebula was taken on a 6mm lens.Materials: It is a study scope and everything does feel robust, but it is a pain too clean. It's very easy to get finger prints on and cleaning the inside is a long process but necessary for good viewing. It should be known that this is the case with almost every telescope, but if you have OCD like me and hate to see finger prints on it, then you'll be cleaning the outside constantly.The oof:Collimation: So, for most telescopes, you'll have to endure a process of collimation. This basically is aligning your telescope so that you'll be able to see objects with more clarity beyond what the focuser can bring. This telescope, doesn't let you do that. It is a fixed collimation. Albeit, coming out of the factory it is near perfect, but I'm unsure how it will last in the long run. The reason this can be bad is because as a beginner telescope, it's important to learn all of the mechanics of basic viewing and collimation is very important to learn.Platform: This is a standard among almost all tabletop dobsonians. They're very awkward to operate. You will find it difficult to find a spot to view with this given it doesn't have a tripod. DO NOT TRY TO MAKE A TRIPOD. There are reasons why dobsonians excel in stability and are genuinely good at viewing. This is something you'll have to find for yourself. I usually go about putting it on my the back of my car and it works just fine. However, in instances when all you have is the ground. It becomes a little more difficult. Larger dobsonians usually are as tall as you while standing up, so this isn't really an issue for those.Why it's better then the FirstScope:For $40 more, you'll get a better red dot finder, better lens, overall better viewing, stronger base, and sturdier materials. The FirstScope is made of dense plastic whereas this is a thin metal sheet. The First Scope comes with plastic 20 mm and 4 mm lens whereas this comes with metal 17mm and 10 mm (also wide angle). THEY BOTH ARE GREAT BEGINNER TELESCOPES. To be honest, if I was more tight on budget, I'd get the FirstScope because I'm still getting a great viewing experience. It is very hard to find good telescopes with this viewing capability under $100. These 70x400 telescopes that are being sold cannot get nearly the images that this is producing. And for a beginner telescope, why would you even want to try and equatorial mount that the Celestron power seekers are advertising. These both are great telescopes, but the z100 is worth, in my opinion, the $40 more then the FirstScope.Conclusion: It's very hard to find telescopes that aren't plastic junk. To be fair, if you've even found this telescope, consider yourself lucky. Many people get doomed by the 70x400 or PowerSeeker hobby killers and never get to see the true beauty of astronomy. It's a pretty clear choice, in my opinion, that this is the best bang for your buck. Great for kids, great for beginners, great for college students wanting something small for their dorm, great for anyone for that matter. It's one of the best viewing experiences I've seen with a telescope under $100. And if you can shell out the money for Z114 or Z130.. do it. Zhumell has done a fantastic job with this line of scopes and I don't see a better product on the market for this price.

Zhumell Altazimuth - Telescopio Reflector portátil 100mm
Es una muy buena adquisición. Es importante hacer notar que para ampliar la capacidad de visualización se requiere más oculares y flitros. Los que trae son básicos y logran una amplificación de aprox 40x. Con oculares adicionales se puede llegar al tope teórico focal de este equipo de 200x. Este límite es también el límite máximo en cuidades debido a la contaminación lumínica

Low cost but with limitations
I bought this on a whim, it arrived in good shape and for the low price it has good optics even with the low cost eyepieces. You need something to sit it on, my solution was a cheap wooden bar stool bought from Canadian Tire, on the bottom of the scope base their is a threaded insert to mount the unit on a standard camera tripod which I tried but found it to be unsteady hence the four legged wood stool, a hole drilled in the middle allowed me to use a short bolt to hold the scope on the stool top with no chance of it slipping off if you knock it in the dark. If you can spend a bit more? the Z114 is the one to buy, almost the same to the Orion Starblast and Edmund Millenium Astroscan 114 with minor cosmetic differences its far more capable and better designed for observing comfort. Also if you have even more money then the Z130 is big enough to keep you busy for many years, however its more bulky and heavy.

A nice, easy-to-use little telescope for the beginner or the casual sky viewer
This is a nice little 'scope for both the beginner and for the experienced user who just wants to go outside and take a look at something quickly. Assembly and setup are VERY quick and easy. The instruction manual is clearly written and straightforward. The laser spotter feature on the spotter 'scope makes locating objects quick and painless.I was initially worried that the lack of a tripod would be a detriment to most sky viewing (because you have to put the 'scope on some surface: a table, fence, or similar) but I found it very easy to just put it on the hood or trunk of my car and start viewing. (The rubber feet make sure that you won't damage the paint job.) The unit is very lightweight and the carrying handle lends itself to "spur of the moment" impulse viewing of whatever strikes your fancy. You can start viewing within five minutes of the time you pick it up. And despite the fact that it doesn't weigh much, it has a surprisingly solid, well-built feel to it.The first couple of nights I had some nice views of Mars, Jupiter (including the Galilean satellites), Saturn, and the Pleides. A few nights later I enjoyed exploring the Moon again. Even in an area with a lot of light pollution (I live near Los Angeles), you can still get in some fun skywatching. One feature I liked about the Dobsian mount was the ability to easily scan of an arc of the sky by slowly rotating the base with the palm of your hand.A couple of minor nits (and they really don't seriously detract from the viewing experience): 1) the slip fit for the eyepieces tends to be very tight, so inserting and swapping out eyepieces can be a little tricky in the dark, 2) the retention set screws for the eyepiece don't always hold them in place as securely as you might like, and 3) locating and viewing objects near zenith can be a little problematic because the upright position of the telescope's body tube means you may have to do some serious neck contortions to use the spotter 'scope. I was able to get around these issues and still thoroughly enjoy using this unit.Overall I'm quite happy with it and have it on my desk next to me for when the sky viewing mood hits!
