Does anyone know (have any pics) what variety of sizes Coulter Optical offered for Ortho's?

On the other hand, I could be wrong.......

But the overall build resembles Circle-T products. In the CN link I posted above, the Coulter kellner (not the ortho, my mistake) has the incised line around the lens housing, which, I think, is also typical of UO Circle-T kellners -- altho I don't have an example on hand. So I'm on the fence about whether or not these are Circle-Ts.
Any comments on how the Coulters perform vs. other Japanese volcano tops?

What were those manufacturers thinking? Never put stickers on optics!

On the silver metallic barrel, it clearly says JAPAN then a circle with a T in it. I would not be surprised if they had different makers through the year.
BTW: A good standard ortho, same view as my U.O. volcano top 12.5mm.

The scope is fast, and I use it typically for deep-sky viewing. So I had a fringe-killer filter, a Baader Moon and Skyglow filter and a stop-down mask to get my best views. Had to let the scope cool down for a while, too. The major belts showed some detail and the Great Tan Spot was easily visible at 116x.
A more 'planetary' scope I'm sure would have done even better.
