Changed my mind on what to get.
« on: December 26, 2017, 11:01:06 PM »
I was speaking to a man at a local telescope shop and he explained a Dobsonian telescope will give me the best bang for the buck.   He explained the picture quality would be better on the 6" Dobsonian than on the" Celestron Omni XTL 150 and it cost a lot less.   Plus I believe I found off to set the telescope in my back and still have one chair free in the trunk. 

The other thing he explained is down the road if I wish to do AP I can mount the Dobsonian on a good Equatorial mount with a drive to do some AP.

So now I believe I am going to get a 8" Dobsonian just not certain one to get.   I've looked online at the next versions.   Big question on those is which is better.   The Zhumell comes with a couple eyepieces and a lot of other things.   The Orion XT8 PLUS comes with a lot of extra stuff and a few upgraded hardware compared to this XT8 can it be worth $160 more.   The Celestron does not really come with much but if it's a far better telescope it might be well worth it.   Also I really don't enjoy buying used equipment even in good shape.   Any guidance from the expert's will be greatly appreciated.     Zhumell Z8 Deluxe $379

Orion SkyQuest XT8 PLUS $499

Orion SkyQuest XT8 $359

Celestron Sky Watcher $449

You could also consider the Apatura AD8 from Opticsmart. It is the same scope as the Z8. Just badged differently and good after sales service.

The AD8 and Z8 are identical as mentioned. Both of these would be a better bargain than the XT8 plus. I think Orion came out with the XT8 plus to try and compete with the better deal AD and Zhumell dobs.Not sure you will want to mount a 48" 6" dob OTA on an EQ mount. That might be too much weight and also a balancing act. More head ache than anything else. You can get a shorter fl 6" if you want a newt for AP.I have been looking at used XT8 dobs to tinker with but might grab me a used Meade 10" lightbridge instead.

Go Zhumell or Apertura. These scopes come equipped with dual-speed Crayfords, a laser collimator, a fan to aid in cooldown, 8x50 RACI viewfinder and tension knobs; all things Orion Dob's leave out. If you were to buy these things separately, it would cost hundreds extra.

This is just my opinion, however. Get what you'd like, but Zhumell/Apertura brands are the bang for your buck within a bang for your buck.

Are the upgrades from the Orion XT8 PLUS worth the extra $160.  it has a Crawford Dual Speed focuser is that any better than the regular one plus a 2" eyepiece.  Or are the AD8 and Z8 just as good as the Orion but much cheaper about $120 less.

Assuming the scope is bigger then 6" then to do any AP you will need a fairly good solid mount to put the scope on.It is something that people here often think of then find the reality is not quite as straight forward as buy an EQ mount and stick the scope on that.Another aspect that occurs here often is the manufacturer say's "DSLR can be attached directly to focuser." You also need the scope to attach a DSLR and achieve focus on the DSLR sensor. Oddly very few can managed to achieve focus. So you have a DSLR on the scope that cannot actually get an image.In general a dobsonian mounted scope and AP do not go well together.

Not worth it IMHO. Orion charges $499 for the same things the Z8/AD8 had all along. You could literally get a Z10/AD10 for less than Orion is asking for an 8" package.

Assuming no difference in the quality of the mirrors, the Zhumell or Apertura is the better deal.  My XT8 was more of an impulse buy from a local telescope store and I did know about the others at the time.  I have not regretted my purchase as I have definitely gotten my money's worth out of my XT8 and have been fortunate to get good mirrors.  The XT8 and probably the others will not achieve focus with a DSLR.  One solution is to move the primary mirror up by replacing the collimation bolts with longer ones which is what I did.  In my case I used 2" bolts to replace the stock 1". Eyepieces will still come to focus with an extender.If you are planning on doing AP with it, I recommend a heavier mount such as the Orion Atlas.  Although, I have had success with my AVX.  The main issue with putting it on an a GEM is that the tube could contact the tripod legs if your target is near the zenith.Check out my entry in the June Beginners DSO Challenge which was taken using my XT8 on my AVX mount.  Scroll down to the 3rd image.Cloudy Nights Beginning DSO Challenge June 2013 The reality however, is that an imaging newt, SCT, or small refractor is a smaller part of the total cost of an AP setup so you will probably end up getting different scopes for AP like what I did.  However, it is still fun to be able to image through my XT8.IMHO an 8 inch Dob is a good compromise between aperture and portability.

You definitely should go Zhumell/Apertura.  The adjustable altitude bearings on them are MUCH better than the CorrecTension springs.  I own both- I know of which I speak.

Personally I like the Apertura line.  I'm considering an 8" myself.As mentioned, you could put the OTA on a GEM mount but you'll need a monster GEM to handle the size and weight.  An EQ6/Atlas at least.  You're better off having a visual scope and a different setup for AP.

He was really stretching the truth on the AP aspect.  But an 8" dob is a very good bang for the buck.

Just for conversation how much did he tell you that new EQ to swing a 20+ lb and 4 foot long 8" Newtonian tube for astrophotography would cost you? Did you see the dollar signs light up in his eyes?

The guy told me the best option would be an atlas mount with a guide scope if i got a dob scope now. Would cost about $2000.  He said i might be able to get a little bit smaller mount but not not much if i want to use the dob. He also said there are much better options for AP out there it all depends on how much i want to spend.I ordered the 8'' Zumell. Am just going to spend the next year or so just learning and will look into AP later

Outstanding idea!

Getting your feet wet on the visual side of this hobby is the best way to start IMO. Enjoy your telescope. 

Astrophotography requires a steep learning curve and is a much more expensive and complicated way of getting started. There is plenty of time for that down the road.
