Is the Zhumell z130 Reflector a good scope?
« on: December 29, 2017, 12:34:37 AM »
Anyone familiar with the Zhumell Z130 table-top reflector scope? Is it a good quality Telescope? How much does the scope weigh fully assembled, is it the same size or bigger then Orion's Star Blast 4.5 scope and how does the Zhumell compare to the Star Blast?

I have been very satisfied with my 130mm f5 OneSky and there's every indication that the Zhumell is an even better implementation of that aperture/focal ratio. It has a "real" focuser that better places the eyepiece and a solid tube with mounting rings. Zhumell's reputation is very good, currently better than Meade's among folks I know. If I was buying one today it'd be the Zhumell. I don't see how you can go wrong.

Regarding the Orion, aperture rules.

The OneSky's 14# total and I expect the Z130's about the same.

You can google up the manual.

The StarBlast is a Synta scope, the Zhumell is a GSO or a Synta. As they say in French "chou vert et vert chou". Which has the better optics tends to change each year (although I've seen some really excellent StarBlast mirrors, at least if you can forgive the not-completely-smooth mass-produced surface finish).

Edite: looks more like a Synta.

The 4.5" StarBlast is an f/4; the Z130, an f/5. There will be less coma with the f/5...

https://starizona.co...cs101_coma.aspx

The 4.5" has a focal-length of 450mm, whilst the 5": 650mm. Therefore, with the Z130 and a 9mm eyepiece, the magnification would be 72x; whilst with the 4.5": 50x. The longer focal-length of the 5" makes it easier to reach the higher magnifications with a given set of eyepieces, and perhaps a barlow in addition.

The purpose of getting a telescope in the first place, compared to binoculars, is to see faraway objects up close. Such would be easier with the 5", therefore my recommendation is...

Incidentally, it's $20 less to boot(since Orion charges $10 to ship).

<p class="citation">QuoteThe purpose of getting a telescope in the first place, compared to binoculars, is to see faraway objects up close.[/quote]

That's not really a problem -- just get a barlow. On the other hand, it's a lot harder to get more field of view, especially with only a 1.25" focuser. The StarBlast really is excellent for wide field observation (although I must confess that I had modified mine to accept a Paracorr, and have since replaced it with a 650mm focal length reflector as well).
f/4, though, is really unkind to eyepieces. At high powers, you'd better use a Plössl only with a barlow combination just to avoid too much spherical aberration generated by the eyepiece!

It's not so clear who is making what these days. Meade is apparently selling Synta made mounts and refractors. Zhumell is a US brand name that used to be reserved for GSO (Guan Sheng Optical, Taiwan) but these days I am not sure, the similarities between the various Synta scopes and the Zhumell 130 lead me to believe it is possible, even likely, that the Zhumell 130 is manufactured by Synta.

You're right, the trim looks a lot more Synta-like than GSO. I had forgotten the Great Reshuffle (since Meade Europe was bought by Jinghua and Meade US by Sunny) that makes products in the US and Europe different these days.

What a _stupid_ idea to put a cover on the back of the Z130, BTW. The only thing that will achieve is make sure the mirror cools more slowly. Fortunately the collimation screws can be exposed if you remove it and ritually burn it.

I own the Z130. Yeah the cover is also an extra obstacle to get to the collimation screws. And we lose the easier to use thumbscrews that the Z130's sister has. I'm pretty sure that the Z130 and Meade 130 Lightbridge come out of the same factory. They're more alike than different.

Overall I like the scope. I think it has a lot of value packed into it. It's great for easy viewing of the moon, planets and just scanning the sky. I'm not terribly impressed with DSO, but that was somewhat expected. I see coma around the mirror's edges with stars which is kind of annoying. You also need a decent table to set it on unless you're going to sit on the ground with it. This has been my number one annoyance with this scope. And it's just what it is due to the small design.

If I had it to do over I would of spent more and bought either the Z8 or Orion 8" DOB. For $200 more you get a full size scope with better features and more aperture. However you gain more weight which may or may not be an issue. Also consider that with Dob's, it's difficult to look at things that are high up (sorry don't know how to better explain it).  A lot of interesting stuff to see as far as DSO are near the Zenith. Less light pollution straight overhead too. So I find that I need to physically move the scope around the yard more to see these objects without contorting my body in uncomfortable positions.

To sum it up: I use the Zhumell Z130. It's fun. But because of the issues I mention I do recommend considering something larger... but not too much.

I have heard mostly all good reviews of that scope.,I have the OneSky version of the 130mm table-topper.,It was easy to build a tripod under it.,but it also sat fine on a milk crate.,If you can observe from just one spot in your yard you can put it on some chimney blocks. Also,if you have a small table to use,if possible,push the legs into the ground a bit.,this will make it much sturdier.,I have found this type of scope quite capable of great views of all types of targets.,I've viewed galaxies down to 11mag. on just average nights.,good luck.,

Never buy an f/4 114mm like the original Starblast, then ;-).<p class="citation">QuoteYou also need a decent table to set it on unless you're going to sit on the ground with it.

And it's just what it is due to the small design.[/quote]I find a crate a lot simpler and more stable (coupled with a small folding chair for campers). On some sites you can also find something ad-hoc on site (like a small ledge).But yeah, I can still remember sitting in the dust in Italy in a field with my legs on both sides of the scope looking at NGC7000. fortunately summer in Lazio is quite dry...

I have a Starblast 4.5. It's a good scope, but sometimes I wish it had more aperture and a longer focal length. Also, at only f/3.9, you have to collimate it frequently and it's difficult to find wide angle eyepieces that work well. The focuser has some plastic parts and Orion doesn't sell any upgraded focusers for it. It is what it is, but it's been my main scope for 3 years now.

The Z130 is a buy in my book. Every freaking day of the week. It has overtaken my 8" as my workhorse. The 8" is a two night a week telescope. The Z130 is an every day telescope. It cools quickly. It weighs nothing. I keep the eye pieces right on the telescope with caps on them. I can grab it and observe at low power in 30 seconds. 15 minutes to cool enough for higher power. It is surprisingly good on planets, fantastic for roaming the sky, and has enough aperture to pull a good amount of DSOs in my red nearly white zone sky. The DSOs aren't as vivid as my 8", but my 8" isn't as vivid as the next guys 12". Don't fall down that slope. The 8" still gets two nights a week if it is clear, but I observe daily now.

Hey Mitch, just curious if you have coma issues with your Z130. I'm still using the stock eyepieces but I believe that I read you use only upgraded ones. I'm not sure eyepieces make much of a difference with coma but I'm curious. I haven't upgraded anything yet because we had high humidity and cloudy skies most of the summer. And then suddenly there was a cool spell and the clouds all went away for a week or two. I was then out enjoying my telescope whenever I could. It sounds like your part of the country has much better viewing conditions than here in Missouri.

130mm Zhumell is a great scope. Scopes twice as expensive are only a little bit better. But you need to put in on something and use a chair. Sitting on the ground sucks after a while.
