Coulter CT-100 4.5", I call it my "laptop" scope

It collapses into two the upper and lower halves which fit in a small leather case. The bar betwixt (betwixt ) the two sections is stored on the stap! Neat.
(The pic shows considerable foreshortening, the two sections are about same size.)

A friend of mine has an early 80s, red sonotube 13.1" Coulter which has a really excellent mirror.
It's a shame that the original company is no longer in business producing these fine old Dob. Newts!
10" F/5 Treckerscope, circa 1956

I didn't have high expectation for this little unit, given the fast design. But, during a quick check out it was pretty good. I was holding by hand, kind of like one would hold a tuba. If mounted, I'm sure I could give a better description of the visual capabilities. Maybe soon.
About 5 of these show up on the Astromart Classifieds going back to 2001. I'm guessing that this may only represent 3 or 4 different scopes. Asking prices range from $90 for one missing the dovetail bar to $500. The others were $295, $350, & $375. One had a helical focuser, which would probably be a nice upgrade. Any focuser would!
I may turn this into double duty as a finderscope!
Astroscan? We ain't got no Astroscan. We don't need no Astroscan! I don't have to show you any stinking Astroscans!

The Swiss Army had a folding scope like this during the '50's, and it still remains hugely collectable (rare) by the militeria folks.

That's a very cool little Coulter. I have seen one of these before somewhere on the web, it may have been your's. I bet if the optics were cleaned and the scope was properly mounted, it should be a good performer.
It would make an interesting Micro-Truss-Dob!
Regards and clear skies,

Other than that it's a nice little scope.
