Thankyou for sharing these pictures. I'm sure you've made a lot of people very envious! I know I am.

I just finished building the 6"f/6.5 imaging scope, and am working on the custom filter wheel.
Using it as the counterbalance was a stroke of....well, it works just fine, sine I have no tripod legs to get in the way.
Placing the EP at eye level when viewing objects at zenith is one really great benefit.
Thanks for your comments.

Really, that's a wonderful scope, you have.
Set up time can be used as *cool down time*.
The offer stands. My scopes would luv a new friend.

Because I am one of the many, *you know your...* guys, I almost enjoy setting up as much as viewing. Set up time is like foreplay. Or something like that.
It never takes over 15 minutes to set up *Little Big Man*.
What takes the longest, is waiting for Polaris to become visible to do a polar alignment.

Just a thought, you could probably trade for a tec140 and be pleased with the results, only .5" smaller and better DSO views, and quicker set up time, and still "portable". And you would use more often?

Rob,
Gee...I don't know...I really enjoy viewing at the zenith, especially in cold, snowy weather. Being able to slide around on my knees while viewing is just...so...WRONG!!
I have to sign off now...as a grown man, I'm told that I should not drool this much. What does my boss know, anyway?

I came to the conclusion a long time ago, that bowing before the celestials would be an act of the heart, not of the physical knee, or the back.... Prostrate is just humiliating
Come out one dark clear night, and experience stable, firm Zenal viewing on your feet.

My every intent is to continually *Have a good one*.
Thanks.

Which are the largest aperture Refractors widely available?
I have a 6inch but are 8inch refractors common ?
From what I gather, 6" instruments are becoming the more popular size, due to mobility, and light gathering ability.
D&G make some very nice large aperture refractors, and TMB probably makes the largest APO's in 6"-12" sizes.
Due to the light pollution issue most are dealing with, 6" appears to be the workable limit. Plus, if you have an endless bank account, 6" is about the finacial limit for most.
But lets not forget the mount that is required to run such a scope. they can be more expensive then the scope themselves.
6"-12"=$8000-$40,000 Aprox.
And mounts to put them on are,
Ap900-Paramount/Parallax=$6000-$40,000 Aprox.
So from that, it isn't hard to see how really *common* these rigs are.
You see very fiew at star parties.
