Description

Designed with you in mind


Zhumell's latest Dobsonian telescope is the result of a new approach to design. Customers like you told us how to improve our Dobsonian, and we listened. Never before has a telescope been so designed with you in mind.


The Zhumell Z12 Deluxe Dobsonian Reflector Telescope features a 12-inch aperture to capture maximum light for clear, long-range viewing. Used in conjunction with the two included eyepieces (30mm and 9mm) and Dobsonian stand, this telescope will make your night-sky observations and star parties more enjoyable than ever.

 

A primary mirror cooling fan brings the telescope into thermal equilibrium quickly, so you can enjoy long viewing sessions without delay. You'll also enjoy the new adjustable azimuth bearing system, which facilitates smooth, even motion when tracking celestial objects. When you arrive at your subject, the dual-speed Crayford focuser allows for quick, easy adjustments, while the laser collimator ensures rapid, accurate optical alignment.

This scope is an excellent value. You get a good quality large mirror, 2 speed focuser, and a RACI finderscope for a very reasonable price. Does it have some problems? Of course, but they are easily dealt with. For instance, the springs that float the mirror cell are far too weak. Problems with holding or adjusting colimation are usually due to these weak springs. Replacements are readily available at your local hardware store or aftermarket telescope stores on the web. Simply replace with stiffer springs...problem solved for just a few bucks.
The include laser colimator works, but it arrived completely mis-adjusted...it was anoying to have to collimate your collimator before you could use it. Check your collimator before you use it and use the three hex screws to adjust the beam so that it is properly aligned. It's not a problem necessarily unique to Zhummel. Info is on the web about this process (search for "collimating laser collimator"). One final complaint would be the cheap particle board stand. It's sturdy enough, but particle board is heavy and it doesn't last forever, especially if it gets wet (heavy dew, perhaps). If you are careful it shouldn't be a problem, but I chose to use the particle board pieces as a template and made my own replacement stand from high quality plywood, stained and sealed with urathane. Again, not really necessary, but I could so I did. Now I have two stands.
A lot of people complain about it being heavy, but I don't think it's that bad at all, and I'm only 5'4" and not in the best shape. It's more awkward due to the shape and size than anything. The tube is 15" in diameter (12" mirror), so keep that in mind. Move it in two pieces, optical tube assembley and stand. I move it outside my house, through a standard door and a good 40 yards across my yard to set it up...takes me about 2 minutes, literally.

Now the good....This scope gives fantastic views of the heavens. The 12" mirror collects a lot of light and many deep sky obects will be within your reach, especially if you have a dark location away from light pollution to view from. The focuser is very smooth, and has no problem handling my largest eyepiece that weighs 2.2 lbs. The 2 speed feature is awesome to have and makes fine tuning the focus much easier, especially at higher magnifications. The movements of the stock stand are smooth and easy in both azimuth and altitude. If you use heavy eyepieces like I do, you may have to adjust the balance point where the altitude bearings mount to the optical tube, which is very easy to do.

Overall, this scope is a great value. If it weren't for the weak springs and out of adjustment laser collimater provided, I would have given it 5 stars easily. It's that good.

First of all, the no hassle return policy at telescopes.com is true. Sadly, I had to return my Zhumell 12 inch telescope because the unit would not remain collimated. Once collimated, the scope worked great. Unfortunately, it was quite cumbersome to have to keep adjusting and collimating the telescope every time I moved the unit. Perhaps it would work best if the telescope were in a fixed location. In all fairness to Zhumell, I had a neighbor help me and offer second opinions. He came to the same conclusion. I wished this scope had worked out for me. I was hoping to have a telescope without the electronics. I would recommend this scope to a friend, but with caution regarding collimation and movement issues. Thank you.

Comments about Zhumell Z12 Deluxe Dobsonian Reflector Telescope:

This should really be amateur astronomy's best kept secret.
It is my first experience with Dobsonian scope.
Assembly was a snap and all required parts were included.
Scope and stand are constructed using durable materials and the tolerances (screw hole alignment etc.)were dead on.
The optics are excellent and the scope may be brought into very tight collimation.
As far as I'm concerned, this scope compares well to others costing 3 or 4 times as much.
The only real con is that it is bulky and heavy but that is to be expected with any Dob.
I recommend this scope to anyone wanting to move up in this hobby. -- Clear Skies!

Comments about Zhumell Z12 Deluxe Dobsonian Reflector Telescope:

I bought this to get the most scope for my buck instead of spending more on electronics and could not be happier. The mirror is sharp and crisp, the 2 inch focuser is very good, and being a dobsonian it is easy to set up and use right away. I added a telrad finder to mine and have been very happy with all of the views I am getting.

Comments about Zhumell Z12 Deluxe Dobsonian Reflector Telescope:

All is as advertised except the 2 inch eyepiece has a large flaw. Warranty states minimum $25 charge for all issues, or I could return entire unit. So I may just keep the eyepiece. Other than that, seems fine. I may have purchased the 10 inch had I known how heavy this was. Planning on constructing small rolling platform to move it outside and back in. I will not leave outside due to particle board base would probably warp/weaken with moisture. Easy to find and track objects. Need a higher mag eyepiece, maybe 3 mm for Saturn. Easy to collimate, use YouTube video if you have not done it before. Very informative.

Comments about Zhumell Z12 Deluxe Dobsonian Reflector Telescope:

So I read a bunch of reviews on the Z12 before I bought it. All of the reviews I read were all extremely positive even though some people had minor problems with the scope. I became one of these people. I ordered it and when it came I immediately fell in love, haha. I have only been into astronomy for a few months and I own a cheap department store refractor and a 130 SLT. So when I got this thing I was blown away by its size and its majestic grandeur (haha). I just wanted to stare at it all day.

Anyways, I tried collimating it and I noticed that when I would tilt the scope up or down, the laser would move in the collimator. I then found out that one of the mirror supports on the back of the primary was loose. This caused the primary mirror to shift slightly when I moved the scope, making it impossible to collimate.

I then decided to join a few astronomy forums for advice. They said that it is an easy fix, but as a beginner, they said it is something that I shouldn't have to deal with after buying a new scope. This is exactly why I ordered from Hayneedle. They have an extremely good return service. So if something is wrong I should have no problem getting a replacement.

So overall, the scope seemed great from the little experience I had with it. The focuser was absolutely outstanding compared to anything I am used to. It is SO smooth and the micro focusing knobs are excellent. The movement of the scope is very smooth in all directions, and adjustable tension as well. The base is easy to put together. Zhumell has a youtube instructional video on putting it together. By the way, it comes with a 30mm (2") eyepiece, a moon filter, built in cooling fan, 9mm (1.25") eyepiece and a laser collimator. I mean come on, how can you go wrong with all of that for $630.

If I can offer any advice of use to you. All I can say is, you get what you pay for. This scope is several hundred dollars cheaper than other dobsonians of the same size. So it would not be unusual if you need to do some adjustments to the scope after purchasing (e.g. some people say the primary springs are weak). But I have read dozens of reviews on this site of people who are extremely happy with the scope. As soon as my account gets refunded for the price of the scope, I am immediately purchasing this again. That should tell you something right there.

      I got "The Fever" after purchasing a smaller telescope. This was a big upgrade to the 90mm refractor we own already. I have only had this out 4 times now, but the views are amazing, even in my light polluted neighborhood. Assembly was easy, and collimation went smoothly. You may need to collimate the collimator first. Easy to do with a tiny hex wrench, and Youtube video. This is BIG! The mirror is 12", but the tube itself measures 14". I have a bad back, and it is not too difficult to move, though I will install nylon straps to lift it with. Amazing bang for the buck!

      Comments about Zhumell Z12 Deluxe Dobsonian Reflector Telescope:

      Although this telescope is quite large, it really packs a punch. Assembly is pretty straightforward (albeit the instructions seemed a little outdated; not everything was exact)and took less than an hour. I love the dual speed focuser, and the finderscope that came with it isn't too bad either.

      The good:
      This scope feels very solid! The base is easy to use, and you can point the telescope in any direction with the slightest force. The primary mirror is pretty big too; I was pretty surprised with what I could see in a well-lit city. This makes a great telescope for beginners, as well as the adventurers.

      The bad:
      I'd say the only (obvious) cons are that it is a very large OTA. While it is possible to move everything by yourself, it isn't easy. The OTA is awkward to carry, and again, very big. The base is also somewhat heavy. Not a deal breaker by any means, just a little inconvenient. Another problem (may or may not be related to the telescope itself) are that the screws come loose somewhat often (once every week or two), so you will want to check up on it before stargazing to ensure that nothing is lost.

      The ugly:
      Really, the only complaints I have are regarding its construction. The collimation screws are very poorly made; I managed to strip them after my second collimation! After replacing the screws, collimation was seamless. The handle on the base (the screws in particular) were also poorly designed. After picking the base up during constriction (to move the base so I could finish constructing it), the handle fell off. I ended up replacing it with my own hardware, so all is well.

      Conclusion:
      I would recommend this scope to anybody thinking about purchasing a dobsonian-stlye Newtonian reflector. It is a fantastic value, and you will fall in love with the view, especially in rural areas. This is my favorite scope, and I am never disappointed when I take it out. It's big, but that's what you're paying for.
