Thanks to its industry-leading optical components, the Z100 outperforms other tabletop telescopes of a similar size for a difference you can see and appreciate under the night sky. With the Z100, Zhumell has put your money where it belongs: into the telescope’s optical system. The Z100’s mechanical design is simple and streamlined. A durable, sturdy construction means your Zhumell will stand up to years of use and travel. Thanks to its compact size and weight, you can confidently pack it along for camping trips, vacations, and more. When you arrive at your observing site, the telescope comes together in seconds. Once you’re set up, swing the scope on its lazy susan-style mount toward your desired object. Center your target in the Red Dot Finderscope, you’re ready to view it through the eyepiece. Then, make small adjustments to smoothly track objects as they drift across the sky. Whether you’re an experienced amateur astronomer or a brand new stargazer, the Zhumell Z100 brings you the night sky on your terms. This convenient, portable telescope is always at the ready to deliver impressive, detailed images, from a quick peek at the sky in your backyard to a marathon night of stargazing.

## Questions & Answers

**Q: How much detail on Jupiter and Saturn can you see on average assuming clear skies and average distance from earth?**
A: You can definitely see Jupiter's Great Red Spot (GRS) with this telescope too. Agreed a 2X Barlow lens is definitely a helpful addition for planetary viewing. Also keep in mind that Jupiter's day is roughly 10 hours long (it rotates much faster than Earth), so the GRS will be visible for 5 hours (as it transits across Jupiter's face) and then won't be visible for 5 hours as it will be on the far side of Jupiter. It may or may not be in view on any given night during prime-time hours.

How much planetary detail you can see on any given night highly depends on what astronomers call "atmospheric seeing conditions" (or just "seeing"). This is a measure of how steady the air is from your ground position, up through the top of Earth's atmosphere. On a night with bad seeing, you won't see fine details -- it will look like the planet is "boiling". Bad seeing is made worse by high magnification, which planets require. Also, be sure to let your telescope's temperature equalize to the outside temperature or you will have bad seeing caused by air currents inside the telescope tube.

By contrast, good "atmospheric transparency" is what you'd need to view dim low-magnification "deep sky objects" (DSOs) like M42 The Orion Nebula or M27 The Dumbbell Nebula. This is a measure of how much light can pass through Earth's atmosphere. This doesn't affect planets because they are much brighter than DSOs because planets are in our solar system, but DSOs are light-years away.

**Q: How do I collimate the primary mirror?**
A: The primary mirror is collimated at the factory and cannot be changed, unless you plan on doing a lot of modifications/customizations. All needed adjustments must be made using the secondary mirror.

**Q: I would like to know how well can you see mars with this?? Any details of the surface???**
A: When Mars was close a few months ago I could see the polar caps and very slight detail. Don't expect to see craters but it's much more than just a dot.

**Q: Anyone know the link to the 2x Barlow glass for the Z100?**
A: You can use any 1.25" diameter Barlow you like.

## Customer Reviews

### ⭐⭐⭐⭐⭐ I picked this over the Celestron FirstScope
*by S***N on January 31, 2021*

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.

### ⭐⭐⭐⭐⭐ Great scope for the price
*by B***D on June 24, 2025*

Great scope for the price, works as intended

### ⭐⭐⭐⭐⭐ So Easy with a little experimentation
*by R***E on October 2, 2023*

Got this for my partner's birthday and we finally had a clear night to test this with. The moon was super bright and almost painful to look at, at first.Setup is easy, just be gentle with the thumb screws for sure. The Red Dot Laser Finder makes it so easy once you figure out the correct alignment. What I'm working on now is a sturdy tripod setup to use it with on a balcony with rails.We sighted in the moon in a few minutes first with the 17mm lens, then after some experimenting we did a bit of looking at Jupiter and Saturn. I could see what I think were the moons on Jupiter as slight blips/dark points. Saturn with the 10x we think we saw the indicators of the rings, but as the aspect matters...YMMV. I plan to order a 2x booster and then maybe add some mid-range lens and a few super high mag like a 6mm and maybe a 4mm.I wish the base's side to side was a bit more stable I'm going to look into those changes in the future also.But the view of the moon was awesome especially as we switch to 10mm once it dimmed a bit later. And this was from a balcony in the DC Area where light pollution is horrible. Taking it on a camping trip soon out of the crazy bright area. Hoping for some clear night looking around.Will update review more in future and hopefully add some photo's once we get that added also.
