How clear would Saturn and Jupiter be with standard eyepieces with the Zhumell z8? Also, what DSO would I be able to view with same scope and good seeing?

I don't have the Z8, but I do have the Z10. Saturn is amazing during nights of good seeing. On June 3rd, we had exceptional seeing and transparency; this summers best by a long shot. During that night, the Cassini Division was tack sharp and so vivid it rivaled AP photos. Banding and color variation was outstanding. That night was the first night I ever saw the greenish-gray of the hexagon. No hexagon shape, just a circle, but wow it was amazing.

As for DSO: Many. Even with my 4" refractor in the city, I can see M13, M31, M42 M57, the Pleiades, etc. An 8" Dob would give some stunning views.

Thank you for sharing. We (me and my wife) decided on astronomy as a hobby we can enjoy together, and get away. I'm the only one who has even looked through a scope! We are both interested, never followed through. So far I've gone from looking at everything from 114mm eq mounts to a z8. Which is about the limit I can go right now. Just want to gain as much as I can before first light. This site and our local library has helped ALOT! I have about settled on the Z8. Just try to learn what to expect.

You'll be able to see thousands of objects in an 8" scope. What they actually look like is difficult to describe, so I really like sketches and drawings as they give a realistic view of what you see at the eyepiece compared to astrophotos. Check out the sketches forum, and I highly recommend Turn Left at Orion as a book to get you started. It has great sketches of 100s of objects with directions on how to find them. It really helped me get a feel for what they looked like, high resolution photos had skewed my expectations.

I would also consider the Apatura AD8 Scope from Opticsmart. The guy in this link just needed a small roller bearing and Hayneedle wanted the whole scope back.

I have owned my Z8 for sometime now, before I got it I didn't think the views were going to be that great coming from a 6" and 8" sct but I was wrong. I really wanted a 10 or a 12" Dob, but due to there size they wouldn't fit in our small car.

I use my Z8 more then anything else now, I love it even in our red zone it's great. At a dark site, less LP yippie...that's we're your jaw drops.
From our red zone we can see a lot, the sky's are little bright "grey color not black" but it's not bad.
I use my Dob mostly for DSO, I enjoy observing nebulae the most. I also use Lumicon UHC and OIII filters these work pretty good with the Z8.
Lunar viewing is awesome, planets "Saturn and Jupiter" are pretty good too. On good nights even in a red zone I can go down to 5mm "240x" no problem viewing Saturn. I even chase down Satellites with it, the ISS blew my socks off the first time I seen it in my Dob.
Here is a short list of Nebula's I like to observe often and look great in the Z8.
Eagle Nebula
Omega Nebula
Trifid Nebula
Lagoon Nebula
Veil Nebula
Ring Nebula
Cat Eye Nebula
Dumbbell Nebula
North American Nebula
There is a lot lot more. Clusters and galaxy's look great to, M3, M5 and M13 almost feel like you can touch them
But yeah I can go on and on, it's a great Dob.

Hello and Welcome to CN!

In my avatar you will see a Z8 dobsonian. When the skies are steady,the scope taken outdoors with the fan turned on for about an hour to acclimate to the outdoor temperatures prior to using the scope,and insuring the telescope collimation is still spot on,the views of Jupiter and Saturn are impressive to say the least.

As for DSO viewing,how dark are the skies at your primary viewing location?

My location is VERY dark. Sometimes deal with clouds though." Turn left at Orion" is in our library. So it looking for astronomy books. Will get it. I am soo glad I found this site! Thank you all for any input and advice. There is only one local person here with any experience that I have found. He told me about the site.

You Sir,are in for some very enjoyable nights ahead.

Under really dark and steady skies,an 8 inch telescope is a very capable instrument indeed. Resolving a bright globular cluster like M13 means seeing literally dozens of star points of light. If you lived in a place like the higher elevations of Colorado with very transparent skies under the same conditions,you could discern the basic shape of the external Galaxy M51 at the eyepiece without having to use averted vision.

Enjoy,enjoy!

I'm at almost sea level, two miles from coast, (Long Beach, MS) but practically NO light pollution at all where we live, and have a 75 acre area in the country that is mine and my siblings with no light at all. Again, I have learned much, firstly just reading posts already asked and reviews. Secondly, getting good feedback from questions. We can't wait!

They will be quite very clear with an 8mm or 9mm eyepiece. With good collimation and good seeing, I have pushed the Z8 to 358x, i.e., with ES 6.7mm barlowed but that was more to see the scopes capability and focus. But 9mm is more than adequate to view both Saturn and Jupiter and other objects. Your 32mm 2" eyepiece will perform well on star clusters. Experiment and adjust and you will soon come to terms with your scopes ability.

www.opticsmart.com i have heard nothing but good things it's pretty much going to be what name you like better at this point between the two.
Now if you didn't have those awesome skies I would say get the AD8 for sure and get the "tweakers dream package" But you really don't need the flocking with your skies but that package does also come with better hard wear but you can always upgrade that stuff later.

Welcome to CN!

Saturn is a very spectacular object. I observed it at 300x through my Z8 on clear nights on Apr 28th and 29th when it was just in Opposition. It was very sharp and big at this magnification, and of course, the Cassini division was easy and obvious, the equatorial bands, Saturnian moons etc. Jupiter will be high enough by the end of the summer. Also very exciting target.

As for the "standard eyepieces", the standards used to vary depending on one's taste. If you mean, Plossls, they should be good, but the field will be quite narrow and you'll have to nudge the scope frequently. So, it's better to get wider field eyepieces, like the ES 82* or Hyperions/Stratuses/AT AF70s or the AT Paradigms/Meade 5000 HD-60/Celestron X-Cel LXs. For the planets on the 8" f/6 Dob you'll need something like 8-9mm (150-133x), 6-6.5mm (200-185x) and 5mm (240x). On the nights with exceptional seeing use 2x barlow for higher magnifications.

The Zhumell 8" Dob would be a really good start. Please, note, it sells with the cooling fan attached and the laser collimator included. Buying a 2x Barlow and the Antares 2" to 1.25" Twist-Lock Eyepiece Adapter will help you with the proper collimation of your future Dob. The Zhumell scopes are really robust quality instruments. I've been using both their 70mm refractor and the 8" Dob and no any complaints so far.

If I see a lot of DSOs on our white/red sky except fainter objects, galaxies, than you'll be able to see practically everything on your dark sky that allows the 8" aperture. For the DSOs don't forget to buy the narrowband UHC filter. In addition to Turn Left at Orion you may consider The Backyard Astronomer's Guide. I'd also recommend to get The Planisphere and the Pocket Sky Atlas . A pair of binoculars also will be useful. Download the Stellarium software to your desktop and any observation planner like this . The Stellarium used to assisting me in planning my observing sessions. It has many useful features including the simulation of a real view of any desired DSO through the scope with any certain eyepiece so I can get an idea what I should expect when observing . When in the field I also use some smartphone Apps . If you get Telrad finder these Messier Finder Charts will make your navigation the night sky easier.

Hope that helps.

I was recently planning to get a Z10, but switched to an AD10 after reading many positive accounts of dealing with Opticsmart. They have been great to deal with so far, and as others have pointed out, they are both identical GSO scopes.

Agree. I had a long conversation with the Apetura/Opticsmart guy at NEAF. He's an amateur astronomer himself and offers cost effective common sense options for these econodobs that no one else does.

If I were in the market for an econodob I would definitely buy from him as opposed to one of the other GSO's or Synta's.

lol, it won't be your only purchase, that's for sure. Some good eyepieces down the road will be the next thing to buy. Most important thing is to get time behind the EP, learn your scope and the night sky. A pair of binos work great too. I use cheap Walmart 10x50 binos to learn new constellations and star hop.

So true. I started out with binoculars to "test the waters" and see if I would actually like astronomy. It wasn't until the Total Lunar Eclipse on Dec 21st, 2010 that I realized I really wanted a telescope. I talked myself into an Omni XLT 102 after a while, and I learned a LOT with this scope. I learned that I am very sensitive to CA. I also discovered how fun the pursuit of the Messier objects are, so I bought a 10" Dob. Then comes the filters, the eyepieces, the solar film for my refractor. As you discover your habits and favorite objects, you'll begin personalizing and buying to fit your needs. After all I have, i'm now in the market for a 4" APO for Grab and Go and quick peeks; there's always something to buy.

One piece of advice I don't see mentioned yet: Get a Telrad!

I am a beginner w/ a Z8 and a very dark home base. I opted for the $600 bundle mainly for the Z100 eyepiece, which I do probably use more than any other EP. But the Telrad that came with the bundle is essential for me. I fumbled with just he RACI finder for the first few nights of viewing, not understanding what the Telrad was going to do for me. When I finally stuck the Telrad on the scope, my ability to find DSOs went up 1000%. I seldom use anything else.

Hayneedle sells the Telrad for about $40, and there is at least one other similar product that does about the same job. Information is pretty to find on laser finders here and elsewhere.

Hey Bob,

Oh yeah.. ISS looks pretty good, depending on it's pass. You can see the solar array panels and everything. it takes some practice do it manually. But I find it easy to do with a Dob, years ago I use to use my classic LX10 Meade 8"sct with a video camera. I used a PVC pipe attached to the OTA to guide/follow lol. The footage wasn't the best, very shacky, but I was able to capture some freez frames. Unfortunately those images are gone due to my apartment being broken in too, they took my laptop back 2007.

There is a few programs out there to use on goto scopes, but I think your LS8 has that built in?

Pretty fun viewing satellites, iss and hst.. I have a lot of apps and software and online sites I use but lately I just been using Satellite Safari, great app by the way.

Hey Jeff,

Cool that you can see panels ect. I believe my LS8 does have a satellite tracking mode and will even set off an alarm to start tracking it. I'll have to do some research on this so I can find some. The ISS moves pretty fast across the sky. What overall EP and power do you use? I would think medium to low with a wide FOV might help?

Thanks,

Bob

Hey Bob,

I'm not familiar with the LS and yes depending on altitude of Satellites they can move pretty fast. I was tracking a R/B "space junk" a few nights ago it was moving along very slow. It's really fun, there is s lot of Satellites and space junk up there, give it ago test it on some satellites that way when you get a nice ISS pass you will have it down.

Lately I have been using my Hyperion zoom 8-24mm EP, that took a while to get use to as well. I would have it at 24-20mm to get the objects in view and with one hand on the tube I would guide/follow and with other hand zoom in and out with the Hyperion. Trust me it's harder at higher magnificents lol. I have had it at 8mm "150" on the ISS and get awesome view of it, but it's easy to lose it at that high of mag. But I will just zoom back out to get it back in my view, what I do before chasing objects I will set my focus sharp as I can get it at 8mm "150" that way when I'm zooming in and out it will be in close focus.

Welcome to CN!

thats a good trick jeff with the zoom ill have to try that!

regarding the focus mask, its not just for astrophotos. Sometimes it can be difficult getting perfect focus especially on certain objects or if your scope has a longer settle time (time it takes to stop shaking after you touch it). Been meaning to get or make one sometime!

Cool thanks guys.

Yes I use my Z8, it's a lot better then when I use to use my Classic Meade 8" SCT.

Rob, I bet it will look sweet in your 10" Meade LB. Also look in to some apps like Satellite Safari or just use the online data. I just prefer using the app so I can see the paths live so I can get my scope ready.

If you have an iPhone or Droid, you'd love ISS Spotter. It allows you to track the ISS and create alarms for the best passes that month. For example, the app says on August 3rd 9:47PM EST the ISS will pass over my location, SW heading NE with magnitude of -3.5, making the pass a 3 out of 3 stars. The alarm will go off on your phone 5 minutes prior so you can get the scope aimed at that part of th sky.

Hubble Space Telescope, that's another nice one too, it's a lot smaller then the ISS. That one makes some very bright passes too. It's amazing up there.. it's like 5pm traffic on a freeway but 24/7 lol.

What is a good Barlow for the z8 that's not too expensive? Also, the lens that come with it, are they ok for the time being without needing an upgrade too soon? I think either the telrad or Barlow should be first to do, but which would you change first?

I used an Orion 2x Shorty for a while. It's a good, inexpensive barlow, but be warned - it has no compression ring. What this means is if you start getting high-end eyepieces and plan to preserve the look for eventual resale, it'd be a poor choice. Both screws lock in and scratch the barrels, dig in and leave "bite marks", etc. I used it for months, but when I began getting serious with my eyepieces, I ugpraded my Barlow.

The two eyepieces that come with the Zhumell are decent. One is a 2" 30mm wide-field, and the other is a 1.25" 9mm plossl. If you plan to observe planets in any kind of detail, you'll likely want to upgrade the 9mm one day. Here is the 9mm that will come with your scope. It gives pleasing views, but it felt like peaking through a keyhole. Here it is again, next to an ES 82 8.8mm (the eventual upgrade.) I still use the 30mm, I like it.

If you are planning to get more EP's down the road, I would say get the Telrad first. a 2x Barlow will make your 30mm a 15mm and your 9mm a 4.5mm
The 30mm is an ok EP I used until I got my Hyperion 31mm. The 9mm I only used once because I had a Baader Hyperion zoom and I used that for my 8mm range.

8-24mm @8mm it's 150x @24mm it's 50x when using it in my Z8.

Here is a link to it so you can look it over and read a little bit about it.

Bummer on not getting the Z8.
When you do get one the 30mm is a 2" ep and the 9mm is 1 1/4. If you get a 2x barlow grab the gso shorty in 1 1/4. You will also need a low-mid power ep, like in the 15-25 range 1 1/4. I like the 25mm because I can barlow it down to 12.5. You don't need expensive ep's to start with, especially when on a budget.

I would get the 2" barolw so that he can barlow the 30mm down to 15mm. The 2" barlow will also come with an 1 1/4" adapter so that he can use it with the 9mm EP also.

I'm a 43 yr old kid, but I'm gonna have to wait or get a LOT smaller scope. Lol... an 8" versus a 4.5 or 5 is worth the wait! Being in south MS a fan wouldn't be much needed, would it? I mean nights here are hot and humid. Doesn't cool much at night anyway unless its winter.

Yep.
A fan is to help cut down the "cool down time" to match up with the out side temperature. Just bring it out side about an hour before viewing, you should be fine. It really depends, but a Dob doesn't take as long as a SCT, so you will be ok. Best thing is to test it, see how long it takes to adjust. This done of course on how everything looks through your EP, if the seeing is bad, all wavy looking its not ready yet. But this also depends how the conditions out are as well. With your scope adjusted to the out side temperature your images through the EP will look sharp and clear.

Thanks Billy! I am so glad I found this site! Everyone has been so helpful. Arrangement made! My son picks it up Sat.in FL, then I have to wait till the 18th when he comes to MS! I can't wait! Thrilled that my wife thought of astronomy as a joint hobby for us. I think she will love it, and I was always interested in it!

Great idea. I didn't know the 2x barlow came with the adapter. I was going to buy a shorty 2x in 1.25 but will get the 2" instead. You learn something new every day.

OP, great news on the 8". Now you just have to wait until you get it.

I'd get the fan to keep the primary cool. I was going to buy the Orion one linked above if I ended up getting a used XT8. The price is very good too.
wow that 2" barlow is fantastic and I love the price. That will be next on the list of must have's.
