Zoom OCA benefits

It might be interesting to contemplate the potential benefits of a zoom OCA. The device can pay for itself with the elimination of even one set high quality wide-field eps.
Observing targets can be aquired at low power and then zoomed to the desired mag level. On a dob this is very handy,
as most dobs are not tracking mounts,when you change eps you run the risk of losing the object.
Another benfit would be the ability to continously vary the magnification while observing the planets at high power to compensate for variations in seeing conditions. One might be able to see just a little more detail this way.
There are probably some benefits I've overlooked but these are enough to set the imagination on fire. I can hardly wait for Harry to bring this to market.

I really like the idea too - either zoom or switch. I think one important factor would be EASY zooming or switching, whatever the mechanical means. Anything that required too much force would be frustrating at higher powers. While it would save the hassle of switching eyepieces, if the object leaves the field when you switch, it would nuetralize much of the advantage.

As this bino-technology marches foward WE benefit! (Ok, so my wallet doesn't benefit, but my eyes do!)

PS But what happens to all those purdy pairs of eyepieces in my box??!!

Clear, sunny skies.
