I had judged against a WO 66SD and found the 60 mm Asahi-Pentax to be the better scope.

Interesting.

 

I'm curious as to "how" it was "the better". Correction? CA? SA? Baffles? Focuser? Build quality? Usability? Fitness for purpose?

 

Normally you'd expect a "little" APO to wax an achromat. And since it's much shorter the moment arm on the mount, you'd expect it to be more solid on any mount. But an inexpensive manufactured item might lack in quality.

 

add:

I remember when the early Nikon APO's came out, they were f/12 - not much different in focal length than the f/15 achromat's they were replacing. There was a substantial improvement with all three of RGB coming to the same focus.

 

I'd expect that any APO would do the same. Perhaps ... they didn't all come to the same focus?

So you essentially threw your body under the scope to prevent the scope getting damaged. Well done. At least you've got your priorities right.

No I was standing right where the scope fell. I like myself too much to get under something that weighs 200 lbs and is falling. It was just luck that I could prevent it from hitting the ground. If one of the other legs gave out it would have crashed down.
