From Orion XT8 to Zhumell Z12 - What to expect?

1. Quality of the Z12? I'm searching now for reviews. Worst thing I've come across is that they often arrive damaged or in damaged boxes.
2. What kind of improvement in view will I see going from 8" to 12"? Will I be able to see more detail/structure in galaxies/nebulae or is that something that requires more aperture (16")?
I realize that some of this comes down to practice at the scope and learning to take the time with each object, just trying to get a handle on what kind of improvement I might expect to see with this change.
There's a pretty good deal on telescopes.com for $699... at least that seems like a good deal, hence my thought to purchase this sooner rather than later.

Expect to be absolutely gobsmacked when you get a dark and steady night. I moved up from a 10" and was blown away by the textures of galaxies and nebula like the Swan, Veil, and Cocoon. Others have posted that the jump from 10 to 12 is moderate- I wholeheartedly disagree. IT IS AWESOME. If you go up from an 8 to a 12, you will have a very hard time ever going back down. You'll become a photon addict.
You can find the Zhumell Mega-Mod thread saved on the Reflectors Forum. You would be joining a community of people who really are attached to the DIY mindset and the bargain-basement access to good, big mirrors. Lots of the posters have included pictures (me included) of their work and offer helpful tips. I hope you'll join us.

In other words, will I look through the 12" and just see slightly brighter objects but no greater detail? My expectation is that the 4" increase will result in at least some increase in the visibility of structure of these objects.

I'm already a photon addict. If I move forward with the purchase I fully intend to see you in the Zhumell Mega-Mod thread!

It sounds like you're already sold but this may clinch it...
the Caldwell Objects start to fall and some are actually fun with a 12 instead of just a challenge to find.

I'm thinking I'll be ordering it tonight

CosmoSat, thanks for the link but the Z12 is already ordered! Should have it by Thursday! Guessing the clouds will roll in about then too!

Hayneedle list it at F/4.93 and 1500mm focal length and 75 lbs.
Interesting, I always thought these were the same scope.
Either there slightly different scopes or somebody is a little off.

Thanks Clay. I am hoping to get a more specific sense of what kind of increased detail I'll be able to see. In other words, when looking at some of the galaxies, will I see structure? Dust lanes? I know I've read that you need a 16" to start seeing the filaments of the Crab Nebula...
In other words, will I look through the 12" and just see slightly brighter objects but no greater detail? My expectation is that the 4" increase will result in at least some increase in the visibility of structure of these objects.
I have both an 8" and 12" inch dob, and these are some of the specific differences I see between the two (from a dark sky site):
1) 12" - The spiral arm on the outer edge of the dust lane of the Andromeda Galaxy is faint in the 12".
8" - Invisible.
2) 12" - The spiral arms of the Whirlpool Galaxy appear with even the slightest averted vision; brighter portions of the arms stand out in moments of good seeing.
8" - The spiral arms are two vague hazes that circle the brighter center.
3) 12" - The brighter arm of the Triangulum Galaxy appears as a lumpy haze that stretches out to NGC 604, the bright star forming region at the end of the arm. NGC 604 itself appears slightly lumpy.
8" - A few of the brightest star forming regions of the spiral arm can be seen with averted vison. NGC 604 is visible, but as a fuzzy blob.
4) 12" - The companion galaxies of NGC 7331 are visible with averted vision.
8" - Forget about it.
6) 12" - The galaxies in Stephan's Quintet can be partly separated in moments of good seeing.
8" - What Stephan's Quintet?.
These are just a few examples of the differences I see, although your results may vary. A 12" will definitely take you into a new range of seeing, just as a 16" will take you into an even higher range. If I didnt' have to drive to a dark sky site, I would have a 16" scope, but as it is, portability is my first concern.

Do you like your 12" Lightbridge? I'm wanting at least a 16" and I'm thinking about getting one. The OP might also want to consider a 12" LB

Very interesting, but what happened to 5?

5 was the black hole at the center of the galaxy.
I like my Lightbridge, and would have no problem buying a 16". With the 10" scope you have now, it might make more sense to save for the 16 - a 2" jump might not be worth the money you could put toward a bigger scope.

Got it tonight with the Z12 on my first serious attempt ever- no filter.

Dennyhenke: The difference will blow your socks off.
Yes, that pretty well sums it up.
