Cave Astrola 12.5"
This OTA on a current high end mount is a 10 because the optics are simply that good. The mount is insufficient as were all of that era, but even at F5 barlowed up to over 700 X on an ideal night Saturn is like a color picture from Hubble in real time.

Cave Astrola 12.5"
I've owned my 12.5" f7 for over 30 years, In those 30 years I've never seen a CAT of comparable aperture perform anywhere near this scope. The stars came into sharp focus flat across the field as tiny points of light (as it should be).
The only down fall of this great scope is its mount. It shakes in the slightest wind, making it difficult for photography. Even if your 6' tall you'll always need a ladder for viewing near the zenith. They don't make em' like this any more.

Cave Astrola 12.5"
I am the original owner of a 12.5 f7 on transportable mount purchased in 1977 for about $1300. Not having an observatory for it but building a permanent pier for the GEM, it's still a monster to carry around and setup. I added handles to the tube rings so I could carry it myself but I'm not as strong as I was in 1977.
I went for the "electric declination" package but by todays standards it's way behind the times. I miss a lot of faint fuzzies because I don't know exactly where I am. To upgrade the mount with encoders is not worth it because it won't correct for the shake in a slight breeze. What is needed is a Losmandy Atlas or some other huge GOTO GEM for the OTA.
I also own a 12" Meade SCT and even though my Cave has a superior view I've found hundreds of objects that I must of passed right over when I used the GOTO.
If your a purist...the Cave is for you, but make sure you know the sky very well and are in good physical shape.

Cave Astrola 12.5"
Cave Astrola 12.5" F/6 manufactured on Jan 22, 1976 #M761380 engraved on primary mirror. Astrola mount 1.5" shafts, 8" diameter pier, rotating rings, RA drive AC 110v, 8x50 finder and 2'' focuser. This scope is an optical masterpiece. The inside and outside of focus diffraction pattern is identical. The detail on Jupiter is enough to keep you busy for hours. Detail on Ganymede is visible under good seeing conditions. The color variations,contrast and sharpness is excellent. The Encke's division on Saturn is routinely visible and subtle differences of colors are visible on the globe and within the rings. Inner ring divisions give the impression of a "combed" or "raked" effect. The Astrola mount is stable and tracks very well. It's got a little backlash but I can live with that. I'm fortunate to have found this scope. It brings a whole new level of observation for me!
