problem is, the larger the zoom range, the larger the compromises you have to accept.
we're just not going to get huge zooms, large FOV's, flat fields etc - some of these are a trade off against each other. That's where I think the Zeiss probably fails you have noted..
If you want something head upwards of 70-80x zoom, you should consider the Leica or Kowa - both have extenders that you add with minimal loss of resolution. The Kowa's 1.6x extenders can be stacked so the 25-60x becomes 40-96x and with a second extender its 64-154x
From what I've read on an astronomy forum - the image is still usable.....
cheers
