The Obsession is of a much higher quality overall than the Orion or Meade scopes. Though I really like my 12" Lightbridge, it must be noted that I have had to fix some issues and upgrade it here and there.

Would I be able to pick out minute detail and crisp structures on Jupiter with the 14 when well collimated?

Thank you folks. I've also been debating for about half the price, an Orion XX14i truss dob. Visually how would it compare with the 12.5 Obsession? Some of my favorite objects to observe are the planets. Would I be able to pick out minute detail and crisp structures on Jupiter with the 14 when well collimated?
Given the choice between a 12 inch Obsession and a 14 inch Orion, I would go with the Obsession. The Obsession will be easier to haul, set up, and take down. A lot of people like the Orions, and I am not putting them down. The best thing to do would be to go to a star party and try them both.

I would go with the Obsession.
I think i'd agree with that myself. Even tho it's certainly not a toss-up for price! The ObDob is still waay more... but for *performance*, optical *AND* mechanical, the modest diff in aperture wouldn't be enough to tip my scales toward the larger.
Yet it might be arguable that the 14i's mirror could even be refigured, and other doodads refined, to where the mechanical diff's might not be quite as significant- and this could probably be done for LESS than the cost of the ObDob new...
But i still recall using a 12.5" Obsession for a few minutes... the views were impeccable! And the movements were like soft butter... and the weight of the components was like feathers. The Orion Dob is a beast by comparison! This aspect would weight (pun intended) heavily in *my* choice... but perhaps not everyone's.

The woodwork is very good on the outside, varnish is fine after nine or ten years. The scope is so good now I cant imagine being without it.

Going to a 12.5-inch from an 8-inch will result in a massive difference in what you can see.
Totally true--a 12 incher gathers twice the light of an 8.

Speaking of new scopes...How much did you pay for the 12.5 Porta Ball? I've reached out Mag 1 but haven't heard back from them...Thanks!

The price on the 12.5" Portaball last year was $5,195....
ouch, I think I may need Ocean's assistance...

12.7" is 2.512X the light grasp of an 8" (exactly one magnitude deeper reach), so the 12.5" is very close to gaining a magnitude on the 8". This doubles and more the number of DSOs visible because there is a much larger portion of universe seen. I've estimated the maximum number of objects visible to the experienced observer in pristine skies at ~15000 for an 8" and ~32000+ for a 12.5".
A 12.5" truss scope breaks down into sections that are easy to transport and move (in fact, my 8" LX200 was heavier overall) and will still yield a nice large low power field.

I saw that ad and called and called Starstructure. I was told that they didn't make it any more. David
