Trying to not blow too much cash. Which one of these Orion scopes do you think is a better purchase? The standard XT8 or the XT6 Plus?

Hello,

Go for the XT8, Aperture wins out. And you can do better picking up better eyepieces and a Barlow. I would start out with a Celestron 8X24 Zoom and Barlow. From there you can see what power Eyepieces you like.( or this will be all the eyepieces you will need) Plus you will at some point, need a collimation tool like a Cheshire collimation eyepiece. ( not nessesary but very helpful) And I would also get a Telrad star finder.( makes finding sky objects as easy as it gets) And at least one filter a Moon filter for bright  Moon viewing. These few extra items are not that expensive.

I'd say the price bump for the XT8, is $70 well spent.  It will significantly outperform the XT6 plus.  Also, it has a two inch focuser, allowing you more flexibility in long focal length (low power) eyepieces.  The standard XT8 doesn't have an altitude clutch, but a welding magnet will help you balance the tube, if you find you need it.  You can replace the collimation bolts on the XT8 with thumbscrews (like the plus) for a couple bucks at the hardware store.

Focal lengths are the same, tube length only differs by an inch, the base diameter is only a few inches wider for the bigger tube, and from what I can tell weight difference is about 6 or 7 lbs.  As long as the price difference or weight is not a deal killer, go for the the 8".  It has a 2" focuser and will be a far more capable scope.  Not that a 6" is a bad scope, but when the sizes are so similar why not go for the 8", unless that few pounds difference is important to the user (moving it around.)

 XT 8  ,  and at f 5.9 its not so fast as too really require a 2 speed  focuser , JMO .    The regular crayford is  simple  to disassemble  and  easy too  work  on   when  needed .

Heya,

 

More aperture and still reasonable in size/weight, they're similar in length if you look and the only real difference is diameter and a bit of weight. You gain a lot for your cash going to the 8 inch. Also, the focuser diameter size of 2" is a good thing in case you want to get a 2" eyepiece that is as wide as you can at some point.

 

Very best,

Thank you all for the info. I’ll go with the 8. Unfortunately, the August availability has now been pushed back to September. bangbang.gif

This backlog of merchandise will be the norm for awhile. Between the Covid 19 shutdown and U.S. China politics. September is not that far away.

For someone who has an XT6, would it be worth going to the trouble of selling it to get an XT8?  Would the jump from 6" to 8" be sufficiently noticeable to do that, for someone who uses it essentially in a backyard in a city, Bortle 7?

Yes, but I would keep the XT6 and use it for a Solar scope or a grab and go scope.

DSO's will be brighter and more defined. The DSO that I use for this test is the Ring Nebula,

Messier 57 in  Lyra.With my 4" refractor it looks like a dim fuzzy star.With my C6 it looks like a larger fuzzy star with a darkened  center, with my C8 you can see the ring. For DSO's aperture wins out. For planetary not as much. For skies that light polluted as yours you might look into EAA. Check this out on the CN Forum on this topic.

Buy it use it enjoy it.  After you've learned what it's all about sell it for $200 or $240 and get the XT8.

You'll be happier with the extra aperture in the long run.

I’d love to buy it, but being that I have a Meade NG90 Mak, a Celestron Astromaster 70, and an Orion 4.5 StarBlast II, I don’t know if the XT6 will be too much in the same category and the XT8 would be the proper next step?

Totally agree.  You will learn more by having the scope.

 

if they were the same lead time, aperture would rule, but you will see pretty much the same thing with the 6" and

life will move on.

Because of the number of scopes I don’t use my SW 6” dob all that much but when I want to I have it, for great, detailed views under Bortle 1 skize ! I had in the past 2 8” SW dobs but I sold them both when I moved into the refractor field and kept the 6” and not because of weight, bulkiness or anything like that, its views were more than enough ! Good Luck and Clear Skiys !

Also remember if you buy the 6” you will always wonder if you should have bought the 8” but if you buy the 8” you will always wonder if you should have bought a 10” but if you bought a 10” you ............ and so on and so on, lol ! That will never change, its always been there so you may as well start with the 6” and move up from there, it is probably inevitable ? Clear skize ahead !

I'd have to ask... After owning the 2.8 inch refractor, 4.5 inch newt, and 3.5 inch mak, which do you prefer using?

 

Why not sell one of these to help fund the bigger scope and make your choice based less on economics and lead time? 

 

Myself....already owning two fairly substantially large telescopes by general non-CN public opinion, I go back and forth thinking I need a third telescope.

 

Half of me wants a small fast 3 to 4 inch medium/high quality refractor as a super fast grab an go.

 

The other half wants to drink the kool aid and get a small 8 inch f6 dob so I can examine the differences of the three main types of scopes in similar sized platforms.

 

The third half wants to split the difference with a semi-fast grab and go 6 inch f6 newt that could split time on any of a homemade dob mount or either my goto eq or manual alt/az mounts.

Actually, I ALREADY started the 8 vs 10 debate! lol.gif

 

I like all three scopes for different reasons. My Celestron refractor is easy to move around and use quickly. The Meade Mak is the only computerized one that I have, and it impresses the chicks! Yes, I have chickens in my yard. And my Orion reflector has a really nice image and a cool looking EQ mount which ALSO impresses the... well, you know.

 

But since I already have 4.5”, I wonder if having a 6” would be that much different. My wife, of course says she’d like 10”.

XT8, still my most used scope. Quick and easy set up.

Bring out the base then bring out the tube and your all set.

I like the blue tube and the light weight so I'd like a XT8 Plus. But I'm not quite sure where the value is in paying over $600 for one of these.

 

The AD8 on the other hand has quite a bit of extras for $100 more than a standard 8 inch dob. Looks like a pretty decent widefield eyepiece, along with a fan, RACI finder, and the better bearing setup as far as I can tell. Still 10 pounds heavier than the XT8 Plus which hampers grab and go-ability some.

This is what I call the "forever fallacy."  A 6" mainland dob is not a "forever" decision.  Once he's figured it out he can sell it and move on to 8" or maybe even will opt for a 10".  

 

The purpose of many scopes, and especially the inexpensive ones, is to lead the willing to their next scope.  

 

Relax, this is not a forever decision.

That is exactly what I meant when I said you might as well start with the 6”, it is a capable scope and the climb will start from there. I really don’t remember mentioning a forever scope but it might be a keeper after the upgrades down the road ?? As you said ‘relax’, lol !
