Upgrade 10" to 12"-is this worth?
Posted 03 January 2013 - 05:47 PM
Will be difference noticable, and how much?
I am not interest for 14" or larger mirrors because of weight, size....

Are you saying that your 10 inch mirror housing will hold a 12?
No, upgrade 10" dob with 12" dob!

I made the step up from 10" to 12", but I was mainly moving from an EQ mount to a Dobsonian with GoTo and auto-tracking. The "wow" factor and bang-for-the-buck was in the improvement in ease of use and portability, not the view.
On the other hand, I made the step up to a 12" to hit my maximum for size, weight and ease of use. I knew I'd never be tempted to go larger. It's hard to judge the value of that satisfaction.

More significantly, however, is as was posted above- if your personal weight/size/transport/cost/etc. "limit" is a 12-inch scope, then by ALL means, *DO* maximize! BUT- if at some point in the near future you suspect your head might be turned toward a 14-15 inch scope, then maybe it's better to wait & see what your true limit really is before taking the plunge. Better to make such a jump in one wise step, rather than two poorly considered ones.
Still, nothin' wrong with BVing a 10" scope! I did that for several years, and had a blast- saw lots of amazing stuff!

I don't know if this 6":5" experience would transfer to the 12":10" experience, but I note that the ratio of the surface areas is the same in both cases.

I would sooner observe with a 10" with great optics than a 12" with good optics. Be careful what you are comparing - 10" vs. 12" alone means nothing.
Good point. If you upgrade, get the best optics you can afford. This is an area to do research.

Edit:I still own my 10 and one thing to consider is upgrading some items on your 10 as many here have done.

So, which mirrors, Orion UK with 1/10 lambda and 97% reflectivity, Zambuto mirrors (I did not found their specifications for mirrors), Discovery Telescopes or....

For sure Zambuto mirrors have a great reputation, so much so that I sometimes wonder if it is over the top. However, if one accepts it as deserved (and I am not claiming otherwise) then it seems like getting a Zambuto optic guarantees excellence (c.f. Roland Christen). I am sure that there are others that folks feel just as strongly about, and one or more of them might be near you? Where I am (Vermont), we are fortunate to have a fellow who does outstanding work, and the views with his mirrors are always as good as (or better than) any in the field. Using a locally made mirror is really wonderful, and I suggest you take advantage of that if at all possible.
Finally, the proof is in the views through the eyepiece and not in the name on the mirror.
