I don't understand what you are implying. Regardless, the good news is that I didn't need to wait for a low astigmatism version of the Zeiss 8x25 Terra because the Zeiss 8x25 Victory, which is much better in numerous ways, is very low in astigmatism off-axis. I bought a Terra on sale ($200) as a gift for a 10-year-old--it's great for its reasonable optical quality, smooth easy to reach focus, very close focus, and low IPD. But for myself, I use the worlds better Zeiss 8x25 Victory, with its slimmer design, better ergonomics, and much better optics.
